On April 22, 2021, President Joe Biden pledged to cut greenhouse gas emissions by 50 to 52% in 2030, compared to 2005 levels.
A statement from the White House writes:
Today, President Biden will announce a new target for the United States to achieve a 50-52 percent reduction from 2005 levels in economy-wide net greenhouse gas pollution in 2030 – building on progress to-date and by positioning American workers and industry to tackle the climate crisis.
According to the Center for Climate and Energy Solutions, net emissions in 2017 were 5,743 million metric tons of CO₂ equivalents, 12% lower than in 2005. Net emissions in 2020 were 21% below 2005 levels and 10.3% lower than 2019 levels, according to a preliminary report by Rhodium Group, but emission levels are expected to rise in 2021 as pandemic lockdown measures are reduced.
Will US greenhouse gas emissions be halved by 2030?
This question resolves positively if there is any year between 2022 and 2030 (inclusive) in which the US levels of economy-wide net greenhouse gas emissions (in terms of CO₂ equivalents) is at least 50.00% lower than 2005 levels, according to a reliable source that is not heavily disputed by other reliable sources. The question resolves negatively if all reliable reports (that Metaculus users can find) say that the US net emissions in each year between 2022 and 2030 were greater than 50% of 2005 levels, and there is at least one reliable report about net emission levels in 2030. (If there is no report about net emission levels in 2030, we should wait for one rather than resolving this question ambiguously.)
If the US gains or loses territories between now and 2030, ideally only the net emissions from the current territories should be considered.
