On the first day of administration President Joe Biden has reversed Trump’s withdrawal from the Paris Climate Accord. The purpose of the Paris Climate Accord is to set out a global framework to avoid dangerous climate change by limiting global warming to below 2°C and pursuing to limit it to 1.5°C. It also aims to strengthen countries’ ability to deal with the impacts of climate change and support them. It will take approximately 30 days for the U.S. to officially rejoin the agreement, but meeting these goals is going to be a difficult task. The U.S. is the second-largest producer of carbon emissions, behind China, and has contributed more to global climate change over time than any other country. Biden pledged to cut all greenhouse gas emissions from the nation’s electric sector by 2035 and to make the country carbon-neutral by 2050. Carbon emissions have been decreasing from the country’s electricity sector as coal plants have been cast aside over the last decade and utilities increase their reliance on renewable energy sources like wind and solar. Industrial and transportation sources of carbon emissions are going to be much harder to reduce. In 2017, transportation overtook electricity generation as the largest source of greenhouse gas emissions in the United States. However, the United States has pledged to do everything in their power to try and reduce these shocking increases of emissions. The United Nations Secretary General Antonio Guterres welcomed the American re-entry into the climate agreement. In an emailed statement, he wrote: “We look forward to the leadership of the United States in accelerating global efforts towards net zero.” Biden rejoining the Paris Climate change reflects to the world that the United States remains invested in making our planet a better and safer place.
