Research and suggestions on achieving carbon neutrality in China's nitrogen fertilizer supply chain
China is a major producer and user of nitrogen fertilizer in the world.The greenhouse gas emissions and intensity of nitrogen fertilizer production and application process are both high.The greenhouse gas emissions throughout the entire lifecycle of the nitrogen fertilizer industry are sorted out,and low-carbon development paths for China's nitrogen fertilizer industry are proposed,including improving nitrogen fertilizer use efficiency,optimizing energy structure and improving energy efficiency,and establishing a carbon trading system.Based on the existing research,the pathway and timetable for the implementation of carbon neutrality in China's nitrogen fertilizer industry are formulated.
