Canadian tar sands to their full potential would be sufficient to bring about what they described as "runaway climate change". The Co-operative Bank were also vocal supporters of the Beaver Lake Cree Nation's legal action against expanding oil extraction in Alberta, raising and donating over C$400,000 to support the BLCN legal case and focusing media attention in the UK – which led to a protest outside the Canadian Embassy in London. Colin Baines, Campaigns Manager at The Co-operative Group described the Beaver Lake Cree Nation legal action as "perhaps the best chance we have to stop tar sands expansion". In 2013, the court ruled in favour of the Beaver Lake Cree on appeal. The Co-op were also involved in shareholder resolutions at BP and Shell's 2010 AGM over this issue of tar sands extraction. A further report published with the WWF was critical of the prospect of carbon capture and storage (CCS) technology being used to reduce the release of carbon dioxide into the atmosphere to a level comparable to that of other methods of oil extraction. In the report they claimed that it was this belief in CCS that the oil industry were using to justify their continued investment in the tar sands. In 2011, The Co-operative Group called for a moratorium on fracking in the UK "at least until all the associated risks are fully exposed and understood". This position was based upon a report which the Co-op commissioned and which was produced by the Tyndall Centre for Climate Change Research. The report concluded that the implementation of fracking in the UK posed three potential problems: the likelihood of increased greenhouse gas emissions; the potential for contamination of groundwater by heavy metals and chemicals used in the hydraulic fracturing process; and the diversion of investment funds away from renewable energy research and development. Another Co-op funded report concluded that the hypothesised emissions benefits from converting from coal to gas (from fracking) had been overstated. As a part of their attempts to increase public awareness of fracking in the UK, the Co-op encouraged members to organise screenings of the film Gasland across the UK. This move received some criticism, notably from The Daily Telegraph due to perceptions of bias in the film Gasland. The Co-operative Group has been a vocal supporter of community-owned renewable projects for a number of years as a way to combat climate change and fuel
