I don’t think “kill fewer people” is splitting hairs.
https://www.washingtonpost.com/climate-environment/2024/08/16/biden-oil-drilling-production/ :
As he campaigned for president in 2020, Joe Biden made a bold promise at a New Hampshire town hall, adding repetition for emphasis: “No more drilling on federal lands. Period. Period. Period. Period.” […] The Biden administration has now outpaced the Trump administration in approving permits for drilling on public lands, and the United States is producing more oil than any country ever has. […] The country is expected to produce 13.2 million barrels of oil per day on average this year — millions of barrels more than Saudi Arabia or Russia.
"producing more oil than any country ever has" is making the biosphere unlivable, and causing a mass extinction which will kill more people.
If enough people vote for green parties, we can reverse anthropogenic climate change and stop the anthropocene extinction. If however we keep voting for the omnicidal lesser evil, then we're voting for omnicidal evil, and complicit in killing more people.
So about 0.272 tonnes of CO2e per year per https://climate.mit.edu/ask-mit/how-much-ton-carbon-dioxide ?
Of a total of about "2.1 tonnes per person annual emissions budget necessary by 2050 to meet the 2 °C climate target (Girod et al 2014)" per https://iopscience.iop.org/article/10.1088/1748-9326/aa7541#erlaa7541r22 (Girod 2014 seems to be paywalled).
That total seems below the 2.1 tonnes of CO2e per year sustainable target per person by 2050.
