The primary sources of greenhouse gas emissions by economic sector in the United States are:
Transportation (28% of 2021 greenhouse gas emissions) – The transportation sector generates the largest share of greenhouse gas emissions. Greenhouse gas emissions from transportation primarily come from burning fossil fuel for our cars, trucks, ships, trains, and planes.
And
The largest sources of transportation greenhouse gas emissions in 2021 were light-duty trucks, which include sport utility vehicles, pickup trucks, and minivans (37%); medium- and heavy-duty trucks (23%); passenger cars (21%); commercial aircraft (7%); other aircraft (2%); pipelines (4%); ships and boats (3%); and rail (2%). In terms of the overall trend, from 1990 to 2021, total transportation emissions have increased due, in large part, to increased demand for travel. The number of vehicle miles traveled (VMT) by light-duty motor vehicles (passenger cars and light-duty trucks) increased by 45% from 1990 to 2021, as a result of a confluence of factors including population growth, economic growth, urban sprawl, and periods of low fuel prices. Between 1990 and 2004, average fuel economy among new vehicles sold annually declined, as sales of light-duty trucks increased.
In the US, cars and the car-centric sprawl it encourages is absolutely the largest single contributor to carbon emissions.
There's a reason that the per capita emissions of the Netherlands are literally half of what they are in the states. It's the cars.
This kind of accounting is about generating clicks, ultimately.
We know the actual fixes for this.
Cap and trade fixed acid rain. Pigouvian taxes like a carbon tax work. Even a revenue-neutral carbon tax and dividend where you split the taxed money evenly among everyone works; it literally pays people to not pollute.
The Green New Deal is a fix.
Novel accounting schemes that generate headlines like this are explicitly not a fix because literally all they do is generate bad publicity for billionaires and ad revenue for the paper. There's nothing real here.
