CEC releases guidelines to improve estimates of North American black carbon emissions

Report recommends methods to enhance accuracy and comparison of black carbon emission inventories

Montreal, 15 January 2016—The Commission for Environmental Cooperation (CEC) has published a report aimed at improving cross-border comparisons and mitigation assessments of black carbon emission inventories between Canada, Mexico and the United States.

The new CEC report is based on an extensive literature review and comparative evaluation of black carbon and underlying particulate matter emission inventory methods, and provides initial recommendations for “best practice” approaches.

A panel—composed of experts from Environment Canada, Mexico’s Instituto Nacional de Ecología y Cambio Climático (INECC) and the US Environmental Protection Agency (EPA)—provided input on the recommendations. Also consulted were emissions research and inventory development experts from North America, Europe and Asia.

The final report, entitled North American Black Carbon Emissions Estimation Guidelines: Recommended Methods for Estimating Black Carbon, provides robust information for major source-sector categories (residential, biomass, onroad motor vehicles, nonroad mobile sources, power/industrial sources, and others), as well as specific sources for black carbon emission factors, activity and speciation factors. Its goal is to offer sufficient detail to allow inventory experts across North America to develop black carbon emission inventories for all sectors.
