绿色创新发展研究院（iGDP）：2024年中国减少一氧化二氮的努力和前景报告（英文版）

Emissions of nitrous oxide (N₂O), a major GHG, are gaining increased attention. Data from the Global Atmospheric Research Emissions Database (EDGAR) indicates that global N₂O emissions in 2023 reached approximately 2.5 billion tons of carbon dioxide equivalent (CO2e), accounting for 5% of global GHG emissions. This makes N₂O the third largest GHG after carbon dioxide and methane. 1 Although N₂O emissions are relatively lower compared to carbon dioxide, it has a strong warming effect, with a
