China's pledge to cut CO2 emissions leaves total undetermined

China plans to cut its greenhouse gas production from the country’s 2005 CO2 level by 60-65% per unit of economic growth in a new pledge ahead of the United Nations climate change talks in Paris later this year, The Guardian reported, citing China’s written submission to the UN. However, China’s is the only national plan submitted that does not set a target based on a fixed value taken from a previous year’s emissions. Instead, the economic carbon intensity range that China has submitted in its latest pledge can vary substantially based on GDP growth rate figures.
