According to the Centre for International Climate Research, carbon emissions have increased by about 0.6% over the course of 2019. The 2019 estimate is based on data through the first nine to ten months of the year, with a few national estimates based only on six months of data. Both the United States and the European Union saw emissions drop 1.7% from 2018 to 2019, but China saw a 2.6% increase and India had a 1.8% rise. China is by far the biggest carbon polluter, with 28% of the 2019 emissions. The United States is No. 2 at 14.5%.
