This report was created as part of one of the demonstration projects of the Black Carbon Diesel Initiative in the Russian Arctic.
The report considers options for black carbon emission reductions through engine repowering, vehicle replacement and engine retrofits. The report found that it is cost-effective for mining companies to replace engines without emission controls with Tier 2 engines. Though Tier 2 engines are more expensive, they are also more reliable, more fuel efficient and cleaner. The analysis shows that mines can recover the additional cost for replacing Tier 0 engines with Tier 2 ones through fuel savings.You may need a PDF reader to view some of the files on this page.
