Limiting global warming to 2 or 1.5°C requires a virtually decarbonized power sector by 2050.The world is not on track to achieve this. In 2018, while renewable energy (RE) generated ¼ of global power, coal produced 38%, and remained the largest source of electricity generation, producing 30% of global carbon dioxide (CO2) emissions.
Limiting warming in line with the Paris Agreement goals requires deep cuts in transport emissions, even as demand for transport continues to grow. Yet under business as usual, emissions are projected to double.
Non–carbon dioxide (CO2) greenhouse gas (GHG) emissions are a substantial driver of climate change and have significant negative impacts on air quality, human health, and food production. In 2014, the last year with official data, non-GHG emissions in China were greater than total GHG emissions in Japan or Brazil.
