The Trump administration has given corporations plenty of convenient excuses to retreat from their climate commitments, with its moves to withdraw from the Paris Agreement, roll back emissions regulations, and scale back clean energy incentives.

But will the world's largest corporations follow its lead?

Some multinational companies have indeed scaled back. For instance, Wells Fargo dropped its goal for the companies the bank finances to reach net-zero emissions by 2050, saying the conditions necessary for meeting that goal, such as policy certainty, consumer behavior and the pace of clean technology development, hadn't fully materialized. Oil giant BP told investors that earlier optimism about a fast transition to renewable energy was "misplaced" given the changing regulatory environment.

However, many others, including the world's largest retailer, Walmart, aren't trading their long-term risk planning for Washington's focus on short-term cost savings. They are continuing their climate policies, but often doing so quietly to avoid scrutiny.

These companies still face ongoing pressure from state and local governments, the European Union, customers and other sources to reduce their impact on the climate. They also see ways to gain a competitive advantage from investing in a cleaner future.
