Halogenated compounds and climate change: future emission levels and reduction costs

OBJECTIVES: This work assesses the contribution to climate change resulting from emissions of the group of halogenated greenhouse gases. METHODS: A bottom-up emission model covering 22 technological sectors in four major regions is described. Emission estimates for 1996 and projection for 2010 and 2020 are presented. The costs for deep cuts into projected emission levels are calculated. RESULTS: The substances covered by this study have contributed emissions of 1100 +/- 800 MT CO2 equivalents per year in 1996. In terms of their relative contribution to emissions of CO2 equivalents, this corresponds to 3 +/- 2% of global emissions of all anthropogenic greenhouse gases. The wide range of uncertainty is due to the poorly quantified net global warming potential of the ozone depleting substances, which have an indirect cooling effect on climate through the destruction of stratospheric ozone. For annual emissions of HFCs, PFCs and SF6 (which are regulated under the Kyoto Protocol and for which global warming potentials are well defined), the relative contribution is projected to increase to 2% (600 MT CO2 eq.) of global greenhouse gas emissions by 2010. This trend is expected to continue, emissions are projected to grow to a contribution of roughly 3% (870 MT CO2 eq.) in 2020 compared to 0.9% (300 MT CO2 eq.) in 1996. For HFCs, PFCs and SF6, this study identifies global emission reduction potentials of 260 MT CO2 eq. per year in 2010 and 640 MT CO2 eq. per year in 2020 at below US$ 50 per ton. These values correspond to roughly 40% and 75% of projected emissions in 2010 and 2020, respectively.     

COS,CS2 and SO2 in aluminium smelter exhaust

Measurements of carbonyl sulfide (COS) and carbondisulfide (CS₂) were carried out on samples drawn from a smoke stack of an aluminium smelter. Volume mixing ratios of 6 ppm COS and 0.1 ppm CS₂ were measured for gases from the electrolysis unit that had previously passed an Al₂O₃ fluid bed reactor and electrostatic precipitators. Specific emissions of 1.6 kg COS and 0.03 kg CS₂ per ton of primary aluminium were found. Extrapolating from this particular smelter’s conditions to a world mix specific COS emissions of about 4 kg/t(Al) are calculated resulting in emissions of annually 0.08 Tg COS into the atmosphere due to electrolytic aluminium production in 1995. Besides the photochemical conversion of anthropogenic CS₂ aluminium production is established to be the second major industrial source of COS probably exceeding automotive tire wear’s and coal combustion’s contributions.     

交通污染区城市绿化植物硫含量分布

为探讨城市绿化植物对交通环境中SO2的响应，以远离城市道路的相对清洁区公园生长的植物为对照植物，采集了广东省被广泛栽种的18种园林绿化植物的不同方位的叶片和树皮样品，用硫酸钡比浊法测定了每种植物样品在交通污染区面向机动车行驶方向、面向人行道方向及相对清洁区的植物样品等不同方位的植物叶片和树皮硫含量，分析了绿化植物在同一株植物的不同生长部位和不同环境中硫含量的分布特征。结果表明，交通污染区所有样品的叶片硫和树皮硫含量均高于相对清洁区的样品。其中，远离工厂的交通污染区生长的同一株植物，离机动车道越近，硫含量越高；靠近工厂的交通污染区的同一植物，离工厂近的部位的植物树皮硫含量高于面向机动车道一侧的植物硫含量。
