President Joe Biden will pledge to cut U.S. greenhouse gas emissions at least in half by 2030 as he convenes a virtual climate summit with 40 world leaders, according to three people with knowledge of the White House plans.
The 50% target would nearly double the nation's previous commitment and help the Biden administration โปรโมชั่น slotxoprod other countries for ambitious emissions cuts as well. The proposal would require dramatic changes in the power and transportation sectors, including significant increases in renewable energy such as wind and solar power and steep cuts in emissions from fossil fuels such as coal and oil.
The nonbinding but symbolically important pledge is a key element of the two-day summit, which begins Thursday as world leaders gather online to share strategies to combat climate change.
The emissions target has been eagerly awaited by all sides of the climate debate. It will signal how aggressively Biden wants to move on global warming, a divisive and expensive issue that has riled Republicans to complain about job-killing government overreach even as some on the left worry Biden has not gone far enough to address a profound threat to the. planet.
The three people who know about the White House plans spoke on condition of anonymity on Tuesday because they were not authorized to discuss the pledge ahead of Biden's announcement.
Biden has sought to ensure that the 2030 goal, known as a Nationally Determined Contribution, or NDC, is aggressive enough to have a tangible impact on climate change efforts - not only in the US but throughout the world - while also being achievable under a closely. divided Congress.
The climate target is a key requirement of the 2015 Paris climate agreement, which Biden rejoined on his first day in office. It s also an important marker as Biden moves toward his ultimate goal of net-zero carbon emissions by 2050.
Scientists, environmental groups and even business leaders had called on Biden to set a target that would cut U.S. greenhouse gas emissions by at least 50% below 2005 levels by 2030.
“Wow. That s ambition with a capital A, "Georgia Tech climate scientist Kim Cobb said Tuesday after learning of Biden's plans.“ That target would put us roughly in line with the most ambitious emissions reductions targets ”projected by scientists and environmentalists.作者: xiaocong7915 時間: 2021-4-29 09:07
