The loss of one major corporation may be considered unfortunate, but to lose four, with another resigning its place on the board, looks like carelessness. Apple has joined energy firms Exelon, Pacific Gas and Electric and PNM Resources in quitting the US Chamber of Commerce. Nike has resigned from its post on the board of the Chamber, and two other firms, General Electric and Johnson & Johnson, have expressed their unhappiness with the business body. Why? Because of the Chamber’s opposition to proposed US climate change legislation, including the Waxman-Markey bill, passed earlier this year by the House of Representatives and now before the Senate. One official at the Chamber even went as far as calling for a commission to examine the science of climate change and determine whether humans are warming the planet to dangerous effect. In a letter to the chair of the Chamber, Apple said it ‘supports regulating greenhouse gas emissions, and it is frustrating to find the chamber at odds with us in this effort.’ The Chamber boasts more than three million members, so most have remained silent on its climate stance. A business body is supposed to speak for its members: does that mean corporate America is largely populated by climate-change deniers?
