Every fall, world leaders meet to discuss climate change. But since last year’s talks, few governments have taken substantial action.
Harry Stevens, graphics reporter at the Washington Post, explained that the purpose of the COP27 climate summit is to gather world leaders and strengthen their commitments to lower greenhouse gas emissions in an effort to combat global warming.
In 2021, 200 countries said that they would make stronger pledges in the next year to help hold global warming at 1.5 degrees Celsius above pre-industrial levels, but only 20 countries actually made stronger pledges.
Projections suggest the Inflation Reduction Act could lower greenhouse gas emissions in the U.S. from 30-40% by 2030, Stevens said.
China has updated its pledge, but it is on track to produce more carbon emissions than would be consistent with holding global warming to 1.5 degrees Celsius, according to Stevens.
