Methodological and Practical Considerations for Developing Multiproject Baselines for Electric Power and Cement Industry Projects in Central America

The Lawrence Berkeley National Laboratory (Berkeley Lab) and the Center for Sustainable Development in the Americas (CSDA) conducted technical studies and organized two training workshops to develop capacity in Central America for the evaluation of climate change projects. This paper describes the results of two baseline case studies conducted for these workshops, one for the power sector and one for the cement industry, that were devised to illustrate certain approaches to baseline setting. Multiproject baseline emission rates (BERs) for the main Guatemalan electricity grid were calculated from 2001 data. In recent years, the Guatemalan power sector has experienced rapid growth; thus, a sufficient number of new plants have been built to estimate viable BERs. We found that BERs for baseload plants offsetting additional baseload capacity ranged from 0.702 kgCO2/kWh (using a weighted average stringency) to 0.507 kgCO2/kWh (using a 10th percentile stringency), while the baseline for plants offsetting load-following capacity is lower at 0.567 kgCO2/kWh. For power displaced from existing load-following plants, the rate is higher, 0.735 kgCO2/kWh, as a result of the age of some plants used for meeting peak loads and the infrequency of their use. The approved consolidated methodology for the Clean Development Mechanism yields a single rate of 0.753 kgCO2/kWh. Due to the relatively small number of cement plants in the region and the regional nature of the cement market, all of Central America was chosen as the geographic boundary for setting cement industry BERs. Unfortunately, actual operations and output data were unobtainable for most of the plants in the region, and many data were estimated. Cement industry BERs ranged from 205 kgCO2 to 225 kgCO2 per metric ton of cement.

大气降尘对土壤重金属累积量估算方法探讨——以重庆市綦江县永新冶炼厂为例

中国的有色金属冶炼企业、矿区周围土壤重金属污染日趋严重.本文对可能造成土壤污染的途径进行了简要分析,并以重庆市綦江县永新冶炼厂为例,分析了冶炼厂排放废气中含重金属颗粒物沉降进入土壤的途径,结合厂址周围土壤中镍含量的监测数据,计算分析了冶炼厂投产30年后,受影响区域因大气降尘引起的土壤镍污染分布状况及趋势,估算得出每年大约有250 kg的镍沉降到厂址周围约4 km2范围内的土壤中,自然沉降率约为32%,为区域土壤重金属污染防治提供了科学依据.
