Driving it Home: Choosing the Right Path for Fuelling North America's Transportation Future, describes the stark energy crossroads that North America faces. Researched and written by the NRDC, Western Resources Advocates (WRA) - both American-based environmental groups - and the Calgary-based Pembina Institute, the report details the clear linkage between growing American demand for transportation fuels and the runaway growth of tar sands development in Alberta's boreal forest. Currently, approximately 60 per cent of tar sands oil production is exported to the United States, but this figure is projected to increase to 75 per cent by 2010. The report can be downloaded from NRDC's website.
