Many of the largest corporations in the United States including Walmart and Apple will stick to the pledges they made to fight against climate change even though President Donald Trump is gutting the environmental policies of his predecessor.

Companies say promises they made, coordinated with the previous White House administration, reflect pushes they have made to cut cost in energy consumption, head off pressure from activists and address risks to their bottom in the years ahead.

Walmart and 80 other companies promised to lower emissions prior to the Paris global emission summit in 2015. The company increased its targets in November of 2016 saying it would receive 50% of its power from sources that were renewable by 2025.

Trump on Tuesday signed an executive order that tells the EPA to reconsider former President Obama’s rules on climate change and it rescinds a number of orders Obama had issued to embed the consideration of climate change in actions of the government from places to lease buildings to whether to approve oil pipeline construction.

Companies must move forward on climate change regardless of what the current White House administration does said a professor in New York on Thursday.

Former EPA head Gina McCarthy said companies do not have the luxury of denying the facts and must invest wisely.

The largest lobbying force in business supports the president on the issue. The United States Chamber of Commerce was pleased with the order made by Trump calling it vital to help stimulate growth.

The chamber argues that the regulations placed by Obama held economic growth back preventing owners of businesses from building much needed roads, pipeline and other types of infrastructure.

The chamber warned as well that the push against climate change would lead to energy prices increasing.

However, many of the members of the group and other titans in the corporate world supported Obama and his Clean Power Plan and if not set up their own climate goals.

Anheuser-Busch InBev, the largest beer maker in the world announced this week it would get 100% of its energy from renewable sources before 2025.

Close to 90 companies made pledges that were similar said an environmental group. CEO at General Electric Jeffrey Immelt in a prepared statement said the company believes that climate change is real and is well accepted scientifically. He added that GE hopes the U.S. will continue to play a role in furthering solutions to these challenges.
