The Commission for a Sustainable London 2012 has been bruised by criticism over Dow’s sponsorship of the wrap that will surround the Olympic stadium, particularly since commissioner Meredith Alexander last month resigned in protest. Campaigners believe that Dow has ongoing liabilities relating to the 1984 Bhopal disaster that resulted in the deaths of an estimated 20,000 people and the serious injury of tens of thousands more. Dow, which bought the owner of the plant in 2001, insists that all liabilities have been settled in full. Commission chairman Shaun McCarthy said that its tight sustainability remit did not extend to acting as moral guardian of the Olympic movement but that it would press for such a role to be created when evaluating sponsors for future Games. In addition to sponsoring the 7m pounds wrap that will surround the Olympic Stadium, Dow has a separate 100m dollars sponsorship deal with the IOC that was signed in. But McCarthy also defended the commission ’s role in evaluating the Dow deal, after Amnesty International wrote to London 2012 chairman Lord Coe to raise the issue. “What has been lost in all of this story is that a really excellent, sustainable product has been procured, we looked at Locog ’s examination of Dow Chemical ’s current corporate responsibility policies and, again, Dow achieved that highest score in that evaluation. We verified that. ” said McCarthy. “As far as the history is concerned and issues around Bhopal, there is no doubt Bhopal was a terrible disaster and snore injustice was done to the victims. Who is responsible for that injustice is a matter for the courts and a matter for others. We have a specific remit and terms of reference that we operate under and we have operated diligently under those terms. ” The commission will on Thursday release its annual review. It finds that “good press” has been made to wands many of Locog ’s sustainability target, but that “major challenges” remain. In particular, the commission found that there was no coherent strategy to achieve a 20% reduction in carbon emissions after an earlier scheme to use renewable energy feel through when a wind turbine on the site proved impractical. “We had conversations with Locog over a year ago about this and said they had to demonstrate how they were going to achieve at least 20% carbon reductions through energy conservation if they ’re not going to do it through renewable energy, ” said McCarthy. “There are some good initiatives, but quite frankly they just haven ’t done it.” Why was Dow ’s sponsorship criticized according to the passage？ A.The products are not sustainable. B.It was related to Bhopal disaster. C.It bribed the London Olympic committee. D.It can ’t reduce 20% of the carbon emission.
