Corporations are finally starting to quit carbon.
The number of companies putting a price on their own carbon emissions has tripled since last year, according to a report released Sunday by the environmental data nonprofit CDP.
By assigning a cost to the production of greenhouse gases, companies hope to establish a financial incentive to wean themselves off fossil fuels. In-house carbon pricing also helps mitigate the effects of current or potential regulation. Carbon prices range from $1 per metric ton of carbon dioxide to $357.
