Evolution of China's NO emission control strategy during 2005∼2020 over coal-fired power plants: A satellite-based assessment.

Since especially the 12th Five-Year Plan (2011-2015), China has made great efforts to reverse the increasing trend of NO emissions through end-of-pipe measures. With the Ozone Monitoring Instrument (OMI) level 2 swath product of tropospheric NO this study explores the temporal-spatial patterns of NO concentrations over China's coal-fired power plants from 2005 to 2020 and investigates the evolution of its control strategy. The nationwide deployment of flue-gas denitration facilities was a critical measure to mitigate NO emissions from coal-fired power plants, while this study externally assesses the implementation gap of their operation.

Evaluating national and subnational CO mitigation goals in China's thirteenth five-year plan from satellite observations.

Good-quality emission data are essential to validate national climate commitments and implement domestic policies. However, conventional bottom-up data collection is costly and subject to potential manipulation by stakeholders when data pass through their hands, which could pose challenges on the efficiency and effectiveness of compliance monitoring especially in developing countries. Satellite observations, specifically OCO-2 XCO measurements, are utilized in this study to develop a relatively independent and timely dataset for screening the attainment statuses of national and subnational CO mitigation goals in China's 13th Five-Year Plan (FYP, 2016-2020).

The potential of CO satellite monitoring for climate governance: A review.

Good-quality CO emission data are fundamental for effective climate policy and governance. Data manipulation should be deterred, while developing countries are generally weaker than developed countries in compiling bottom-up CO emission inventories due to less adequate data collection capacity. This paper assesses the capabilities of CO satellites as objective, independent, potentially low-cost and external data sources for monitoring energy-related anthropogenic CO emissions at regional/national, megacity and point-source geographical scales.
