The world’s top carbon polluters – China and the United States – have reached a landmark agreement on greenhouse gas emissions, with both countries pledging to curb them by about a third by 2030.
Under the agreement, which was announced by President Obama and President Xi Jinping in Beijing, the United States pledges to reduce the level of its greenhouse gas emissions – based off 2005 levels – by 26 to 28 percent by the year 2025. Ultimately, the goal for American policy makers is to reduce emissions 80 percent by 2050.
For its part, China has pledged to stop its emissions from rising by 2030 – the first time the country has ever promised to reach such a goal. President Xi said that in order to successfully accomplish this, 20 percent of China’s energy needs will come from alternative sources by 2030, such as solar power and wind energy.
