[ GHG Emissions in Major World Blocs ]
The data from the table shows the evolution of greenhouse gas emissions from a historical perspective to the year 2021. Notably, China's emissions increased dramatically from 13% historically (1850–2021) to 30% in 2021. The United States saw a reduction from 19% historically to 11% in 2021. The EU27 also reduced its share from 13% to 7%. India's share grew from 4% historically to 7% in 2021. The 'Rest of G20' and 'Rest of world' categories saw decreases in their emissions shares from historical levels to 2021, from 25% to 18% and 20% to 21%, respectively.
The table presents data on greenhouse gas emissions across various regions. It has three columns: the first column lists the regions, including Russia, China, the United States of America, EU27, India, Rest of G20, and Rest of world. The second column shows historical carbon dioxide emissions from 1850 to 2021, and the third column displays greenhouse gas emissions for the year 2021.
