The achievement possibilities of the EU 2 °C climate target have been assessed with the ETSAP TIAM global energy systems model. Cost-effective global and regional mitigation scenarios of carbon dioxide, methane, nitrous oxide and F-gases were calculated with alternative assumptions on emissions trading. In the mitigation scenarios, an 85% reduction in CO2 emissions is needed from the baseline, and very significant changes in the energy system towards emission-free sources take place during this century. The largest new technology groups are carbon-capture and storage (CCS), nuclear power, wind power, advanced bioenergy technologies and energy efficiency measures. CCS technologies contributed a 5.5-Pg CO2 annual emission reduction by 2050 and 12 Pg CO2 reduction by 2100. Also large-scale forestation measures were found cost-efficient. Forestation measures reached their maximum impact of 7.7 Pg CO2 annual emission reduction in 2080. The effects of uncertainties in the climate sensitivity have been analysed with stochastic scenarios. 相似文献

The pesticide atrazine,its degradation products,and 2,6-dichlorobenzamide(BAM) are persistent in groundwater environment.We studied whether their dissipation can be enhanced with a mixture of a complex carbon source and zero-valent iron(ZVI) called EHC.The application rates were 1.0% and 2.0%(by weight) in subsurface sediments slurries(atrazine 30 mg/L),and 2.0% in 1.5 m pilot-scale sediment columns with groundwater flowing through(atrazine 0.08,desethylatrazine DEA 0.03,BAM 0.02 μg/L).In the slurries under aerobic conditions,atrazine of 0.88 ± 0.14 mg/g of EHC was dissipated chemically,as concentrations did not differ significantly between the slurries and their sterilized controls.No degradation occurred in the slurries under anaerobic conditions.In the pilot-scale columns under water-saturated conditions,atrazine,DEA and BAM were not detected in effluents during 33,64 and 64 days from the beginning of the water flow through EHC columns,respectively,but thereafter traces of compounds could be detected.No atrazine or degradation products(BAM,DEA,deisopropylatrazine,desethyldeisopropylatrazine) could be extracted from the column sediments at the end of the experiment.As a result,the sum of dissipated pesticides was about7.6 μg/g of EHC in columns under water-saturated conditions,and 0.88 mg/g of EHC in slurries under aerobic conditions.EHC can be used to enhance the dissipation of studied pesticides in small quantities,preferentially under aerobic conditions. 相似文献
