　　Last month BSkyB, a British satellite-television company chaired by Mr Murdoch and run by his son, James, declared itself “carbon-neutral”, having taken various steps to cut its discharges of carbon into the atmosphere.

　　The army of corporate greens is growing fast. Late last year HSBC became the first big bank to announce that it was carbon-neutral, joining other financial institutions, including Swiss Re, a reinsurer, and Goldman Sachs, an investment bank, in waging war on climate-warming gases. Last year General Electric (GE), an industrial powerhouse, announced that it will cut its output of greenhouse gases and to invest heavily in clean technologies. In October Wal-Mart announced a series of environmental schemes, including doubling the fuel-efficiency of its fleet of vehicles within a decade. Tesco and Sainsbury, two of Britain's biggest retailers, are competing fiercely to be the greenest. And on June 7th some leading British bosses lobbied Tony Blair for a more ambitious policy on climate change, even if that involves harsher regulation.
