Many companies are supporting cap and trade because they will make lots of money if it passes (e.g. General Electric) or they think it is better for their bottom line to be at the table working out this bad policy instead of fighting it.  I’m sure there are other self-serving reasons as well that are motivating some of these companies, such as public relations. 

Regardless, these companies, by supporting cap and trade, are supporting:

– Higher energy prices
– Less disposable income
– Weakening the economy
– Fewer jobs
– Hurting the poor (since a cap and trade is regressive)

You can see lists of many of these unethical companies here.  The organization that has developed these lists, called the No Cap and Trade Coalition, is asking people to boycott these companies.
