Carbon capture and storage (CCS) involves capturing carbon dioxide released by power stations and other industrial sources, and burying it deep underground. The report shows that while CCS may have an overall positive effect on air pollution, emissions of some pollutants may increase.
An offset is a measurable reduction, avoidance, or sequestration of GHG emissions from a source not covered by an emission reduction program. In this way, offsets would complement the more traditional emissions trading that can occur between two covered sources. what would have happened anyway).
A two-year study led by researchers at the University of Toronto has found large trucks to be the greatest contributors to black carbonemissions close to major roadways. The difference between emission levels across the sites was more correlated with the number of large trucks on the road rather than number of cars. 8b01914.
