Many of America’s biggest corporations including Apple Inc. and Wal-Mart Stores Inc. are sticking by their pledges to fight climate change even as President Donald Trump guts his predecessor’s environmental policies, Bloomberg reports.

Companies say their promises, coordinated by the Obama administration, reflect their push to cut energy costs, head off activist pressure and address a risk to their bottom line in the decades to come.

“This work is embedded in our business,” Wal-Mart spokesman Kevin Gardner said in an email. It’s “good for the business, our shareholders and customers; if ultimately we are able to positively impact the environment in the process, that’s a win too.”

Wal-Mart was one of 81 companies that promised to reduce emissions in the run up to the 2015 Paris global climate negotiations. The company upped its targets last November, saying it would get half its power from renewable sources by 2025.

Trump signed an order Tuesday that tells the Environmental Protection Agency to reconsider former President Barack Obama’s climate rules, and rescinds a series of orders Obama issued to embed consideration of climate change in government actions from where to lease buildings to whether to allow oil pipelines to be built.
