By Katie Fehrenbacher, Fortune.

A handful of some of the largest U.S. companies including WalmartNikeStarbucks, and Salesforce have committed to buying clean energy that comes from solar and wind.

The nine mostly Fortune 500 companies took a pledge on Wednesday to join what’s called the “RE100,” a campaign created by the non-profit advocacy organization The Climate Group and environmental data company CDP. The announcement coincided with Climate Week NYC, a week-long event in New York focused on climate change, organized by The Climate Group.

The companies, which also include Johnson & Johnson, Goldman Sachs and Procter & Gamble, plan to buy clean energy to reduce corporate carbon emissions, as well as align their corporate image with the environment.
