I don't understand how these numbers work. When we commit to cutting emissions by 50%, what is the base of that number? Our total emissions today? If a significant part of this involves electric vehicles, that means at least 25% of all vehicles on the road probably need to be electric, including semis (currently it's 1%).
All of this just seems unrealistic right now with 7 years to go. Without a way to limit consumption through carbon tax, I don't see how the status quo really changes. All of this seems ripe for playing number games.
These things remind me of someone commiting to lose weight for their new years resolution.
Drilling into the linked sources a little bit, the baseline is 2005 emissions, which is roughly the peak of US CO₂-equivalent emissions. Right now, we're ~15% below 2005 emissions.
But... are we actually 15% below in total, or just per capita? I've heard/read both from various places (all of which escape me now). We might still be emitting more in total, but because of population increase, we're considered 'down' from 2005.
(And shale gas is one of the reasons for the drop... gas power does better for CO₂ emissions than coal is, and the fracking boom basically killed a lot of the coal industry.)
Per capita, the US is down ~25% from 2005 levels (from ~20t to ~15t).
> (And shale gas is one of the reasons for the drop... gas power does better for CO₂ emissions than coal is, and the fracking boom basically killed a lot of the coal industry.)
Natural gas is better in isolation at point-of-use, but that assumes that none of it escapes into the atmosphere at any point along the (literal) pipeline - which, as it turns out, is not a safe assumption, due to shoddy pipelines. As a greenhouse gas, natural gas is actually a few orders of magnitude worse than carbon dioxide[0], so if even a very small amount leaks out it not only wipes out any gains you get from using natural gas instead of coal, but quickly becomes a solution that's worse than the problem.
We probably haven't seen the worst of it yet: in practice, companies have very little long-term liability for the environmental impact of the mining infrastructure as it ages and after it is abandoned, at which point it becomes an effective pump of greenhouse gases into the atmosphere. With nobody else responsible for the expensive task, it will probably be up to the government to clean it all up.
Methane is a strong GHG with a global warming potential 84 times greater than CO2 in a 20-year time frame. Methane is not as persistent a gas and tails off to about 28 times greater than CO2 for a 100-year time frame.
So, methane is shorter-lived in the atmosphere than CO2. We need good numbers, of course, to have a good decision.
> Methane is a strong GHG with a global warming potential 84 times greater than CO2 in a 20-year time frame. Methane is not as persistent a gas and tails off to about 28 times greater than CO2 for a 100-year time frame.
That was already discussed in the article I linked. A 100-year timeframe is not relevant for either the 2005-present timeframe or the 2050 goal, which are the benchmarks being discussed.
It wasn't mentioned in the comment itself. And of course 100-year timeframe behavior can hint at much shorter timeframe behavior, which is quite relevant.
Terrible idea: grassroots movement that releases the highest short-term GWP but shortest-lived gas into the atmosphere (Hydrogen?). The idea being humanity isn't going to seriously address the topic until the pain ramps up to a certain level, and that happening from a gas that will dissipate by itself leaves us in a much better position than carbon dioxide that will have to be sequestered to remove it.
EVs are getting so much cheaper so fast that they'll overtake ICE and hybrid sales soon... but vehicle stock in the US turns over slowly
I've seen predictions that at some point it'll be cheaper to get a new EV than to even keep gasoline in an old ICE car, and once we hit that point it'll flip quickly. 7 years feels tight for that, but not impossible
There is zero chance of mainstream manufacturers being able to reach 50% EVs in 7 years. The supply chain capacity for batteries and other components simply can't ramp up that quickly regardless of customer demand.
The mainstream manufacturers have invested a lot very quickly into the supply chain for batteries. It is ramping up extremely fast. Many of the current supply issues seem to be that it is ramping up too fast and there is a bit of a "hysteresis effect" as new plants come online with early plant quality issues that just need time to smooth out.
Several of the mainstream manufacturers have 100% EV goals in 7 years or less. (All of the German manufacturers do, and GM is said to internally have a similar goal despite the kid gloves they treat their shareholders with because US shareholders have too much love for ICE and would tank GM's stock if GM actually said that out loud.)
I simply don't believe your claim that GM is misleading their shareholders about EV plans. The Board isn't stupid enough to commit that type of securities fraud. Citation needed.
Sorry, I don't think they are "lying" about anything to their shareholders and "kid gloves" was an attempt to describe what I think they are doing. I think they are playing a PR game trying to A/B test PR messages depending on the shareholders in question. Some PR messages are about GM is on a very fast track to electrification. Some PR messages are about GM still believes in ICE. Investors that were leaving in droves for Tesla or Rivian stock want to hear the first message. The big investors that are also dealers want to hear the second message for the time being (until they feel more comfortable selling EVs, and/or find ways to better monetize EV-related "services" in the ways they make most of their money selling ICE, and/or GM finally buys those dealers out in one way or the other).
In neither side of the A/B test do they make too many "definite" statements of what their timelines are for full electrification or for selling their last ICE. Reading between the lines of the EV statements (as the type of investor that believes EVs are the present), their electrification speed has been mostly remarkable and leaves the impression that the GM board isn't as stupid as previous decades' boards have been and knows what the German timescales are (and has some idea of the existential threat of the Chinese car manufacturers that are 100% EV already today) and is trying to stay relevant/competitive in modern timescales. That's admittedly a very personal gut reaction of "hearsay" to intentionally wishy washy PR statements.
You're not making any sense. What are the actual conflicting messages? None of GM's franchised dealers are also major GM shareholders. The real major shareholders are more concerned about labor costs and strikes than about the pace of electrification.
"We are also moderating the acceleration of EV production in North America to protect our pricing, adjust to slower near-term growth in demand, and implement engineering efficiency and other improvements that will make our vehicles less expensive to produce, and more profitable."
I just came back from a road trip to the US. It seems a lot of people there drive insanely big pickup trucks for no other reason than fancying big stuff. I wonder how EVs fit into that picture. Are we talking very big electric cars or are we expecting them to transition to small + electric at the same time?
Actually, even in Europe, cars are getting bigger and bigger. SUVs are very much on the rise, and small cars are getting bigger too.
It's not so much a technical issue than consumer preferences at that stage. Without financiary incentives, I don't see consumers shifting to small/EVs cars
The F150 Lightning sold so well they stopped taking preorders because the production was fully booked for more than a year. There will certainly be holdouts but folks that want huge vehicles will still get them but electric. Nothing but cost prevents big electric cars, and those gas trucks already often cost 60k+
> lot of people there drive insanely big pickup trucks
Depends on the region. By just solely concentrating on drivers in urban areas like the Bay Area, LA-SD Metro, Mid-Atlantic, and Chicagoland you can make a large enough dent to impact emissions.
Most of these metropolitan areas are a good fit for electric cars, and in some of these (Bay Area and DMV) around 20-30% of the cars I'd see are Teslas alone.
In general, a road trip within the US won't be a representative slice of the US as most of the population is concentrated in the Mid-Atlantic (Boston, NYC, DC), California (LA, SD, Sacramento, Bay Area), Chicagoland, and Texas (Austin, DFW, Houston).
I think there must be a cost-per-kwh where big trucks just get big batteries, and fast chargers get fast enough to push them. but we don’t seem to have hit that yet

P.S Start to look for the pattern in the rest of life, it makes things interesting...
Care putting those numbers into perspective with say, the amount of money the government has poured into the housing bubble over the past twenty years? A quick search says the current balance sheets of Fannie and Freddie are $5T. Money, especially fiat money that is conjured on a whim, is an abstraction and I'd say it's much better to have it directed to strategic purposes than squandered as aimless handouts to asset holders.
We could easily get to net zero much, much sooner than 2050 by planting a lot more trees. It would be fun and planting trees has many other benefits besides capturing CO2.
Planting more trees (and, more important, preserving existing trees) is an important tool in the toolkit, but shouldn't be overestimated, and I don't think the word "easily" is warranted.
Project Drawdown estimates that 3.2 to 4.96 Gt CO₂/y could be sequestered (through 2050) using a combination of tropical forest restoration, temperate forest restoration, and tree plantations on degraded land. The upper figure is only about 10% of worldwide emissions: significant, but not a game-changer. And the projects involved would be nontrivial, to say the least.
This is the kind of thinking that happens when consultants, smart people, environmentalists, statisticians, and politicians get in the same room to write a report to save the planet.
Planting a tree to save the environment is not simply about the carbon it "sequesters". There are huge positive externalities to planting a tree that come in various forms.
E.g. Something as simple as planting a fruit tree in your backyard. Just imagine these effects:
1. Buying less fruit at shops
2. Less fruit being transported
3. Kids growing up with free food grown from the land
4. People buying land that allows planting a fruit tree
5. People (and their kids that watch) learn about taking care of their surroundings
6. Responsibility to care, prune and water a fruit-bearing tree.
7. Poor communities fed by a tree mean less aid means less 1st world carbon spending for fake 3rd world "feed the poor" brownie points.
8. More fruit rotting on the ground means less fertilizer.
9. More fruits means more birds means more seeds being peppered along the landscape.
Sadly, as with carbon credits, this tree planting concept has been "captured" by opportunists and they just have you give them money so they can "plant" a tree easily on your behalf somewhere halfway around the world so you don't have to worry about it.
I'm honestly not sure what your point is. Are you saying that, if there was less cold quantitative analysis of the global CO2 potential from forest management, people would be planting more trees in their local neighborhoods?
Absolutely, trees can provide many benefits separate from CO2 absorption. I was simply responding to GravityLab's comment about CO2. However, it's also worth noting that planting the wrong trees or in the wrong place can backfire: displacing more appropriate vegetation; fire risk; etc.
Yes, planting trees is easy but it is the maintenance. To make sure the trees planted are taken care off until they are grown enough to survive on their own is a task and an expense.
It's a significant amount of trees - smaller than I thought, but perhaps the largest megascale project ever attempted. ~230B trees which is ~7.6% of the global tree stock.
Another advantage to grasslands is that grasslands help control the tick population. Ticks like shady spots like trees and bushes. They dry out in grasslands.
Every square meter of forest absorbs enough CO2 to offset about 1 Watt of carbon fuel use. The average US inhabitant uses about 10kW on average. About half of US energy use is from fossil sources and the population is about 300 million. So we'd need 150 million new hectares of forest, growing forested land from 1/3 of the country to 1/2. Which is honestly a lot more doable sounding than I'd thought it would be before running the numbers.
EDIT: Eventually the forest will climax and start emitting as much CO2 as it absorbs but that's a lot of time to solve the problem at a more fundamental level.
Even in the US, "IRA" commonly means "Individual Retirement Account" … which of course makes no sense in context. (Or, the IRA you're thinking of, too, isn't that unfamiliar.)
Even the correct expansion, "Inflation Reduction Act" … doesn't really seem to fit.
When I lived an hour from Boston (where a lot of Irish people with money used to send money to the Irish Republican Army) there was the joke that "Contributions to the IRA are not tax deductible" based on the double meaning such that contributions to an Individual Retirement Account are tax deductible.
> A 600-plus-page report from the National Academies of Science includes 80 recommendations for how the U.S. can achieve its target of net-zero emissions by 2050.
The National Academies of Sciences, Engineering, and Medicine release a 600-page report:
> Addressing climate change is essential and possible, and it offers a host of benefits - from better public health to new economic opportunities. The United States has a historic opportunity to lead the way in decarbonization by transforming its current energy system to one with net-zero emissions of carbon dioxide. Recent legislation has set the nation on the path to reach its goal of net zero by 2050 in order to avoid the worst consequences of climate change. However, even if implemented as designed, current policy will get the United States only part of the way to its net-zero goal.
It looks like there was a huge windshield bias among the authors. In the chapter on Transport, they describe transit as a targeted subsidy only for those unable to afford EVs, instead of what it should be, which is the central feature of the transportation system that is enjoyed by everyone. They barely mention bicycling and do not mention e-bikes which are hugely outselling EVs.
FTA: It also estimated that there were nearly 25,000 emergency room visits for e-bike injuries more broadly in 2022. The two-wheelers also have been involved in a spate of high-profile fatalities in recent years, especially in the Big Apple.
--
in my opinion, ebike accidents are following the same pattern as motorcycle accidents pre-hurt report. make sense. From a road handling perspective, both vehicles are functionally identical. Singletrack, small contact patch, counter steering, navigation, situational awareness, and braking skills. It's long past time requiring a ebike driver's license showing that one has taken a skills focused training course like the MSF program.
That report is impressively vague about the cause and characteristic of these non-fatal injuries. The CPSC is obviously looking at this from a product safety lens, but that isn't necessarily the true picture from a holistic perspective. At least they're quite clear when it comes to the fatalities:
>Collisions with motor vehicles were the leading cause of death associated with e-bikes
>Motor vehicle accidents were the leading cause of death associated with e-scooters
So is the potentially unsafe product we should be concerned about e-bikes and scooters? Or is it actually motor vehicles?
The product we should be concerned with is the ebike operator In the quote below, the issues of loss of control, single bicycle accidents etc. all parallel the data found in the Hurt report on motorcycle accidents. Motorcycle riders were able to drop their accident and injury rate by better training of the rider.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9100098/
>Current research mainly analyzes injury-monitoring data. Studies have shown that 27.6% of fatal bicycle accidents in the Netherlands involved EB in 2017 [10]; in Israel, a total of 3686 hospitalized cases were related to EB during 2014–2019 and 84.92% oral and maxillofacial injuries were attributed to EB [11]; and in the United States, there were 130,000 ERTI cases from 2000 to 2017, accounting for 5.3% of the total number of injuries in the emergency department. Among them, 17% of EB caused serious injuries such as traumatic brain injury and internal hemorrhage [12]; in Switzerland, the incidence of ERTI is 17%, and the main causes of injuries are road skidding, riding too fast, and being unable to maintain balance [13]. Langford used GPS technology to analyze the safety behaviors of EB cyclists in a complex traffic environment. The results showed that violations of traffic lights and driving on motorways are high-frequency dangerous riding behaviors [14]. Haustein et al. conducted a questionnaire survey on EB users in Denmark, and the results showed that the riding attitude of cyclists has a significant impact on heavy ERTIs [15]. After analyzing the accident data recorded by the Swiss police in 2011 and 2012, Weber et al. found that ERTI was dominated by Single-Bicycle Crashes (SBCs) [16].
Considering that the linked study doesn't even bother defining e-bike, and the study setting is China, I am unwilling to imbue the report with the meaning that you intend.
Increased injury severity and hospitalization rates following crashes with e-bikes versus conventional bicycles: an observational cohort study from a regional level II trauma center in Switzerland
The fastest certified off-the-shelf e-bike goes to 28 mph and usually max out at 20mph, which is far below the usual speed of motorcycles. Of those 25,000 ER visits, very few are fatal, and of 1,260 bicyclist deaths in 2020, 806 were from collisions with vehicles. It seems cars are the problem, and this can easily be addressed by adding protected bike lanes and dedicated bike paths. By providing safe cycling routes, other countries such as the Netherlands have been able to see a large-scale transition from auto transportation to cycling with very few accidents, ebike or not.
Compare these numbers with motor vehicles (especially how pedestrian deaths by motor vehicle are skyrocketing), and it's clear that our priorities should be placed on safe pedestrian and cycling infrastructure, not by regulating ebike usage.
To point, it doesn't matter how fast you going. If you follow the bike, you have a higher G Force just from the vertical drop. Your head and body don't decelerate that fast sliding forward. You will get the same amount of road rash if you fall off and e-bike or a motorcycle one at the same speed.
The number 1 best way to reduce accidents between different kinds of vehicles is training people to drive consistently and predictably. Personally I think someone should not get a license to drive until they've shown have mastered driving three types of vehicles (singletrack, dual track light weight, dual track-heavyweight).
What are you talking about? Your response ignores the most basic facts about physics (kinetic energy = (1/2)mv^2) and vehicular safety (speeding kills). And what do you mean by 3 types of vehicles? Did you have ChatGPT generate your response or something?
From a naïve perspective, you are right. However, the physics of falling off a moving vehicle is more complicated. You have the downward G forces under gravity which do not change with forward motion. The deceleration going forward is a function of how how much your skin/clothing adds friction. The curbstone/light posts scenarios do happen but ERs are not filled with those cases. It's the road rash cases.
Three types of vehicles are singletrack like motorcycle, bicycle. Two wheels oriented on on the same line in the direction of travel. uses countersteering., Dual track, four wheels relatively light mass such as cars or small pickup trucks. Dual track heavyweight which may not be something are familiar with if you didn't grow up with trucks. It's a truck with two wheels in the front and four or eight wheels in the back. Usually require CDL to drive. All of these vehicles handled differently under the same road and weather conditions.
If you train and build skills outside of your normal day-to-day usage, you'll build a cope with the unusual more easily and in this case, be a better driver.
As for your speed kills simplification, it's momentum that kills. How fast you decelerate. Speed kills is for people who aren't knowledgeable of physics and how it applies to their day-to-day life.
I think it is underappreciated how an incentive to reduce emissions from a particular government often shift emitting activities to a different place rather than reducing emissions.
Given that there would be little agreement for a new universal governance of human activity, one might think using existing governance structures might be a route. Unfortunately this may not the case. As an example, the recent changes in cargo ship fuel sulfur emissions may have just shifted emissions from atmospheric to oceanic. [0]
IMHO the best way forward is to lean into diffusing technological progress so that the most economic method of different human activities is also the least emitting. These methods may sometimes be initiated or gestated by subsidy but ultimately have to stand on their own, and they must be evaluated by total impact, not just shifting impact.
This is far from true. China has invested the most of any country into both renewables and nuclear power. Their per-capita emissions are far below that of other industrialized countries, and they are now leading the way in technology. That said, they still remain a large user and importer of coal, especially inland (where they are focusing on transitioning to nuclear).
The atmosphere does a very good job of mixing CO2, so that a ton of emitted CO2 does the same harm to everyone no matter who emitted it.
It follows then that unless you can make a good case that some people have some sort of natural or divine right to emit more CO2 (and thus cause more harm) than do others the correct way to allocate whatever total worldwide CO2 budget we have is to give each person an equal share.
It follows then that each country's fair share of the worlds total CO2 budget is proportional to the population of the country. China has 4.2x the population of the US, but is only emitting 2.2x as much.
Both are over their far share of the world's current emissions, but the US is more over. China's emitting 85% more than their fair share. The US is emitting 207% more than their fair share.
> Their per-capita emissions are far below that of other industrialized countries
Not really. Here's per capita CO2 emissions of the 10 countries with the highest industrial outputs, plus the EU as a whole and the world as a whole.
14.44 United States
12.13 South Korea
10.8 Russia
8.73 China
8.46 Japan
8.33 Germany
7.77 EU
6.12 France
5.2 United Kingdom
5.03 Italy
4.7 World
2.29 India
> Their per-capita emissions are far below that of other industrialized countries
Per-capita emissions don't matter. Every ton of CO2 contributes the same to global warming regardless of the population of the country that emitted it.
It's because "per-" means different things in "per-capita" and "per-country". In "per-capita", we're dividing emissions by population to get a single number. In "per-country", we're listing the individual emissions of each country. If "per-country" were instead just the total global emissions divided by the number of countries of Earth, then it indeed wouldn't matter either.
> Is Vatican City the best model of a sustainable climate paradise?
Not necessarily, but it is the wrong place to focus if your goal is to reduce total emissions. Imagine trying to optimize a computer program that takes 4 hours to run. If one function's total runtime during the program's execution is 100 milliseconds, even if it's super inefficient and could be rewritten to run in 1 millisecond instead, doing so is not useful progress in speeding up the whole program.

I'm glad the other meaning is being forgotten.
Project Drawdown estimates that 3.2 to 4.96 Gt CO₂/y could be sequestered (through 2050) using a combination of tropical forest restoration, temperate forest restoration, and tree plantations on degraded land. The upper figure is only about 10% of worldwide emissions: significant, but not a game-changer. And the projects involved would be nontrivial, to say the least.
If you're interested, I dug into this topic in some depth in a blog post a little while back: https://climateer.substack.com/p/forestation-2.
Planting a tree to save the environment is not simply about the carbon it "sequesters". There are huge positive externalities to planting a tree that come in various forms.
E.g. Something as simple as planting a fruit tree in your backyard. Just imagine these effects:
1. Buying less fruit at shops
2. Less fruit being transported
3. Kids growing up with free food grown from the land
4. People buying land that allows planting a fruit tree
5. People (and their kids that watch) learn about taking care of their surroundings
6. Responsibility to care, prune and water a fruit-bearing tree.
7. Poor communities fed by a tree mean less aid means less 1st world carbon spending for fake 3rd world "feed the poor" brownie points.
8. More fruit rotting on the ground means less fertilizer.
9. More fruits means more birds means more seeds being peppered along the landscape.
Sadly, as with carbon credits, this tree planting concept has been "captured" by opportunists and they just have you give them money so they can "plant" a tree easily on your behalf somewhere halfway around the world so you don't have to worry about it.
Absolutely, trees can provide many benefits separate from CO2 absorption. I was simply responding to GravityLab's comment about CO2. However, it's also worth noting that planting the wrong trees or in the wrong place can backfire: displacing more appropriate vegetation; fire risk; etc.
https://en.wikipedia.org/wiki/Team_Trees
A far cry from 230 billion, but enough that it wouldn't seem like an impossible project for a few world governments to collaborate on.
Another advantage to grasslands is that grasslands help control the tick population. Ticks like shady spots like trees and bushes. They dry out in grasslands.
EDIT: Eventually the forest will climax and start emitting as much CO2 as it absorbs but that's a lot of time to solve the problem at a more fundamental level.
Even the correct expansion, "Inflation Reduction Act" … doesn't really seem to fit.

The National Academies of Sciences, Engineering, and Medicine release a 600-page report:
> Addressing climate change is essential and possible, and it offers a host of benefits - from better public health to new economic opportunities. The United States has a historic opportunity to lead the way in decarbonization by transforming its current energy system to one with net-zero emissions of carbon dioxide. Recent legislation has set the nation on the path to reach its goal of net zero by 2050 in order to avoid the worst consequences of climate change. However, even if implemented as designed, current policy will get the United States only part of the way to its net-zero goal.

FTA: It also estimated that there were nearly 25,000 emergency room visits for e-bike injuries more broadly in 2022. The two-wheelers also have been involved in a spate of high-profile fatalities in recent years, especially in the Big Apple.
-- in my opinion, ebike accidents are following the same pattern as motorcycle accidents pre-hurt report. make sense. From a road handling perspective, both vehicles are functionally identical. Singletrack, small contact patch, counter steering, navigation, situational awareness, and braking skills. It's long past time requiring a ebike driver's license showing that one has taken a skills focused training course like the MSF program.
>Collisions with motor vehicles were the leading cause of death associated with e-bikes
>Motor vehicle accidents were the leading cause of death associated with e-scooters
So is the potentially unsafe product we should be concerned about e-bikes and scooters? Or is it actually motor vehicles?
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9100098/ >Current research mainly analyzes injury-monitoring data. Studies have shown that 27.6% of fatal bicycle accidents in the Netherlands involved EB in 2017 [10]; in Israel, a total of 3686 hospitalized cases were related to EB during 2014–2019 and 84.92% oral and maxillofacial injuries were attributed to EB [11]; and in the United States, there were 130,000 ERTI cases from 2000 to 2017, accounting for 5.3% of the total number of injuries in the emergency department. Among them, 17% of EB caused serious injuries such as traumatic brain injury and internal hemorrhage [12]; in Switzerland, the incidence of ERTI is 17%, and the main causes of injuries are road skidding, riding too fast, and being unable to maintain balance [13]. Langford used GPS technology to analyze the safety behaviors of EB cyclists in a complex traffic environment. The results showed that violations of traffic lights and driving on motorways are high-frequency dangerous riding behaviors [14]. Haustein et al. conducted a questionnaire survey on EB users in Denmark, and the results showed that the riding attitude of cyclists has a significant impact on heavy ERTIs [15]. After analyzing the accident data recorded by the Swiss police in 2011 and 2012, Weber et al. found that ERTI was dominated by Single-Bicycle Crashes (SBCs) [16].

Must-Know E Bike Accident Statistics [Latest Report]

look at solo bike accident rates. you will see this kinds of accident reports increase until we change how we train how people ride.

Compare these numbers with motor vehicles (especially how pedestrian deaths by motor vehicle are skyrocketing), and it's clear that our priorities should be placed on safe pedestrian and cycling infrastructure, not by regulating ebike usage.

Some hard data on the bike accidents and the kind of injuries that occur. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9100098/ then read the Hurt report
The number 1 best way to reduce accidents between different kinds of vehicles is training people to drive consistently and predictably. Personally I think someone should not get a license to drive until they've shown have mastered driving three types of vehicles (singletrack, dual track light weight, dual track-heavyweight).
https://nacto.org/publication/city-limits/the-need/speed-kil...
Three types of vehicles are singletrack like motorcycle, bicycle. Two wheels oriented on on the same line in the direction of travel. uses countersteering., Dual track, four wheels relatively light mass such as cars or small pickup trucks. Dual track heavyweight which may not be something are familiar with if you didn't grow up with trucks. It's a truck with two wheels in the front and four or eight wheels in the back. Usually require CDL to drive. All of these vehicles handled differently under the same road and weather conditions.
If you train and build skills outside of your normal day-to-day usage, you'll build a cope with the unusual more easily and in this case, be a better driver.
As for your speed kills simplification, it's momentum that kills. How fast you decelerate. Speed kills is for people who aren't knowledgeable of physics and how it applies to their day-to-day life.
Given that there would be little agreement for a new universal governance of human activity, one might think using existing governance structures might be a route. Unfortunately this may not the case. As an example, the recent changes in cargo ship fuel sulfur emissions may have just shifted emissions from atmospheric to oceanic. [0]
IMHO the best way forward is to lean into diffusing technological progress so that the most economic method of different human activities is also the least emitting. These methods may sometimes be initiated or gestated by subsidy but ultimately have to stand on their own, and they must be evaluated by total impact, not just shifting impact.

Why inflict enormous economic damage on the U.S. when any benefit will be drowned in the actions of the rest of the world?
Place your effort where the problem is.

It follows then that unless you can make a good case that some people have some sort of natural or divine right to emit more CO2 (and thus cause more harm) than do others the correct way to allocate whatever total worldwide CO2 budget we have is to give each person an equal share.
It follows then that each country's fair share of the worlds total CO2 budget is proportional to the population of the country. China has 4.2x the population of the US, but is only emitting 2.2x as much.
Both are over their far share of the world's current emissions, but the US is more over. China's emitting 85% more than their fair share. The US is emitting 207% more than their fair share.
Not really. Here's per capita CO2 emissions of the 10 countries with the highest industrial outputs, plus the EU as a whole and the world as a whole.
Per-capita emissions don't matter. Every ton of CO2 contributes the same to global warming regardless of the population of the country that emitted it.
It's because "per-" means different things in "per-capita" and "per-country". In "per-capita", we're dividing emissions by population to get a single number. In "per-country", we're listing the individual emissions of each country. If "per-country" were instead just the total global emissions divided by the number of countries of Earth, then it indeed wouldn't matter either.
> Is Vatican City the best model of a sustainable climate paradise?
Not necessarily, but it is the wrong place to focus if your goal is to reduce total emissions. Imagine trying to optimize a computer program that takes 4 hours to run. If one function's total runtime during the program's execution is 100 milliseconds, even if it's super inefficient and could be rewritten to run in 1 millisecond instead, doing so is not useful progress in speeding up the whole program.
