煤炭生产企业碳排放状况分析研究

通过对原煤开采环节能源消耗构成和副产物排放的分析研究,提出把煤炭开采环节的碳排放分为能源消耗产生的碳排放和系统副产排放产生的碳排放两大类。详细分析了原煤开采过程中电力消耗的碳排放、煤炭消耗的碳排放、油品消耗碳排放及煤层气排放所引起碳排放的排放源和排放量及其核算方法,简单介绍了伴随煤矸石与矿井水排产生的少量碳排放。提出煤炭生产企业的碳排放总量的计算公式为：Q=Q1＋Q2＋Q3＋Q4＋Q5＋Q6＋Q7。     

武汉市道路交通业CO_2排放与减排潜力分析

为了促进武汉市低碳经济发展,减少交通出行带来的碳排放压力,核算了武汉市道路交通出行的CO2排放量,并采用低度、中度和强化3种减排情景模式对武汉道路交通出行的碳减排潜力进行了测算,计算出了不同情景下武汉市道路交通出行的碳减排强度。结果表明,2005年以来道路交通业CO2排放总量呈显著增长趋势。私家轿车的CO2排放量增加速度最快,大货车的CO2排放量在各类交通工具排放量中占比最大,公交车和出租车的CO2排放量所占比例较小。对3种不同情景的模拟结果表明,在低度减排情景减排效果有限,强化低碳情景下才能达到减排效果。建议采取以下减排措施:改进基础设施,创建良好的出行环境;推进技术创新,降低机动车能耗污染;提升公民素质,加大碳减排的宣传力度;优化道路运输的能效和经营效率管理等。

哈尔滨市节能环保产业发展现状及对策

在国家大力推行节能减排的形势下,哈尔滨市节能环保产业规模日益壮大,总体水平有所提升,但还存在产业结构不完善、产业规模小、技术水平不高、资金投入不足等问题。就目前国家形势和市场环境来看,节能环保产业未来发展前景良好。在发展对策上,建议制定产业规划,开拓融资渠道,制定税收优惠政策,提高企业技术水平,发挥大型企业的带动、支撑作用,加大对节能环保产业的扶持力度,使其逐步成为哈尔滨市支柱产业。     

A review and evaluation of nonroad diesel mobile machinery emission control in China

China’s emission control for nonroad diesel mobile machinery (NDMM) must deal with a fast increase in stock as well as regulations that are two decades behind those for on-road vehicles.This study provides the first large-scale review and evaluation of China’s NDMM policies,along with emission measurements and an investigation on diesel fuel quality.The sulfur contents of the investigated diesel declined from 430 ppm (median value) in 2011 to6-8 ppm during the 2017-2018 period.The emission contr...     

Suggestion on further strengthening ultra-low emission standards for PM emission from coal-fired power plants in China

China has established the largest clean coal-fired power generation system in the world by accomplishing the technological transformation of coal-fired power plants(CFPPs) to achieve ultra-low emission. The potential for further particulate matter(PM) emission reduction to achieve near-zero emission for CFPPs has become a hotspot issue. In this study,PM emission from some ultra-low emission CFPPs adopting advanced air pollutant control technologies in China was reviewed. The results revealed tha...     

Advances in air pollution control for vessels in China

Vessel emissions have contributed a great deal to air quality deterioration in China. Hence,the Chinese government has promulgated a series of stringent emission regulations. It is in this context that vessel emission control technology research is in full swing. In particular,during the 13th Five-Year Plan, the air pollution control technology of vessels has greatly improved. Vessel emission control has followed two main governance routes: source emission reduction and aftertreatment technology...
