Climate change is one of the greatest challenges for human beings in the 21st century. The Paris Agreement proposed that all countries should work together to keep global temperature rise this century well below 2 degrees Celsius, and even more aggressively, to limit it within 1.5 degrees Celsius. Chinese government has integrated climate change into national economic and social strategic plans, granting green development as a cornerstone of high-quality economic growth. Through high-quality data and rigorous research, we strive to support China’s energy transition and long-term decarbonization by providing insights and recommendation to decision-makers, helping the country peak its carbon dioxide emissions as early as possible and achieving the ambitious carbon neutrality goal and vision towards long-term resilient development. Since 2008, our Climate and Energy Program has been working with relevant government agencies, research institutes and business to support national 30·60 targets and explore sustainable options for climate change.
