Abstract. A long-term, robust observational record of atmospheric black carbon (BC) concentrations at Fukue Island for 2009–2019 was produced by unifying data from a continuous soot-monitoring system and a multi-angle absorption photometer. This record was then used to analyze emission trends from China. We identified a rapid reduction in BC concentrations of (−5.8 ± 1.5) % y−1 or −48 % from 2010 to 2018. We concluded that an emission change of (−5.3 ± 0.7) % y−1, related to changes in China of as much as −4.6 % y−1, was the main underlying driver. This evaluation was made after correcting for the interannual meteorological variability, by using regional atmospheric chemistry model simulations (WRF/CMAQ) with constant emissions. This resolves current fundamental disagreements about the sign of the BC emission trend from China over the past decade, assessed from bottom-up emission inventories; our analysis supported inventories reflecting the governmental clean air actions after 2010 (e.g., MEIC1.3, ECLIPSE v5a and v6b, and REAS updated) and recommended revision to those not (e.g., CEDS). Our estimated emission trends were fairly uniform over seasons but diverse among air-mass origins. Stronger BC reductions occurred in regions of South-Central East China, accompanied by CO emission reduction, while weaker BC reductions occurred in North-Central East China and Northeast China. Prior to 2017, the BC and CO emission trends were both unexpectedly positive in Northeast China during winter months, possibly influencing climate at higher latitudes. The pace of emission reduction over China surpasses those of SSP1 scenarios (SSP: shared socioeconomic pathways) for 2015–2030, suggesting highly successful emission control policies. At Fukue Island, the BC fraction of PM2.5 also steadily decreased over the last decade, suggesting that BC emission reduction started without significant delay with respect to other pollutants, such as NOx and SO2, which are among key precursors of scattering PM2.5.

To reach the peak of carbon emission in China, the energy and power industry has the most arduous task and the heaviest responsibility. It should not only ensure efficient economic development, but also complete the arduous task of energy conservation and emission reduction. It is the main force in helping reach the peak of carbon emission. Taking the achievement of carbon peak in China’s power industry as the research object, this paper utilizes time series analyses to establish CO2 emission prediction models for China and its power industry under two scenarios: with and without a carbon peak target. The paper analyzes the current status of achieving carbon peak in China’s power industry and puts a forward CO2 emission reduction scheme for China and its power industry in the future. On this basis, countermeasures for China’s power industry to deal with carbon peak are explored.

The intellectual environmental management can be realized accurately by applying the technology of the Internet of Things (IOT) to sense the environmental monitoring object and to precede the data mining application based on the monitoring. Taking Shanxi Province’s environmental IOT system as an example, this system had been achieved real time monitoring .The monitoring data has been applied to the total pollutant emission reduction verification, pollutant emission charge, administrative penalties, total pollutant emission dynamic management, pollutant emission allowance trade, and environmental mobile law-enforcing system, which provides a solid platform for the environmental management .Applying the technology of the IOT, using the “Whole Circle”environmental management, combining the environmental economic means, the innovation in methods, mechanism and supervision of environmental protection system can be realized.

In this paper, in considering the influence of interaction and material decomposition, the generation of NOx inside the rotary kiln and precalciner, which are the main NOx emission equipments in cement production process, are simulated by CFD technology, and the results is tally with the actual situation. This shows that numerical simulation can be a very good guidance on NOx emission reduction technology and staged-combustion precalciner structure design, and we can design and optimize the NOx emission reduction scheme based on numerical simulation to achieve the purpose of reducing NOx pollution in cement production.
