Many world leaders are gathering in Madrid, Spain to discuss how to reduce the world’s temperatures. As they meet, China is expected to receive a lot of attention. China is the largest producer of carbon gases linked to rising temperatures. China burns about half the coal used in the world each year. Coal is a fossil fuel that releases carbon dioxide and other gases when it is burned. Between 2000 and 2018, China’s yearly carbon gas emissions increased by nearly two hundred percent. China now releases about 30 percent of the world’s total. However, China is also the leading market for solar energy devices, wind turbines and electric vehicles.
