In Autumn 2014, TGG released a highly publicized expert report, Economic Costs and Benefits of the Trans Mountain Expansion Project (TMX) for BC and Metro Vancouver, in collaboration with Simon Fraser University’s Centre for Public Policy Research. The report, published in November 2014 and re-released in February 2015, refuted Kinder Morgan’s claims regarding positive economic development benefits of its controversial pipeline project (TMX). Goodman and Rowan of TGG estimated the economic benefits of TMX for BC and Metro Vancouver and compared these benefits to a range of potential costs of bad to worst-case scenarios. TGG demonstrated that the economic benefits of the pipeline were very small and had been significantly overstated by Kinder Morgan, whereas the worst-case costs of a catastrophic spill were very large and had been vastly understated.
