Toxic and Fine Particulate Emissions from U.S. Refinery Coking and Cracking of 'Tar Sands' Oils.

The Natural Resources Defense Council sponsored this research to develop a quantitative estimate of potential greenhouse gas co-pollutant emissions from a possible future shift to Canadian heavy oil feedstock across the U.S. refining sector.  Access the report.


Testimony regarding the Interim Investigation Report, Chevron Richmond Refinery Fire.

The U.S. Chemical Safety Board invited this expert testimony, which helped to support new local and state requirements for inherently safer oil refining technology, in its April 2013 hearing on this catastrophic pipe rupture and fire.  Access the written testimony document.

Combustion Emissions from Refining Lower Quality Oil: What Is the Global Warming Potential?
