I recently came across a very intriguing speech by Sir Terry Leahy, the head of Tesco PLC. Tesco is a British based supermarket and consumer goods retailer which recently announced the opening of a zero carbon supermarket in Ramsey England. In the speech before the Sustainable Consumption Institute scientific conference at the Royal Academy, Sir Leahy lays out both the imperative to control carbon emissions and a vision of the role of business in achieving an 80% reduction in carbon emissions by 2050. I do not hear big business leaders in the U.S. articulating this kind of vision. Sir Leahy would be an excellent guest on a future program focusing on climate change and Copenhagen.
