U.S. businesses are serious about addressing climate change. “We’re seeing that [commitment] in many, many ways,” says Todd Stern, U.S. special envoy for climate change.

Eighty-one ways recently.

Just as world leaders were set to gather in Paris for the U.N. conference of parties, known as COP21, to discuss climate action, that many companies — 81 — representing more than $3 trillion in annual revenue expressed support for a global agreement.

They not only look for a successful Paris summit. They #ActOnClimate every day through their business operations, while looking to their own profits and boosting the U.S. economy.

Apple Inc., the world’s largest tech company and maker of the iPhone, is taking a bite out of its carbon emissions. Since 2011, it’s lowered emissions per product and expanded use of renewable energy. Today, 100 percent of Apple’s U.S. operations and data centers run on renewables, some of which it purchases from producers. It plans to produce 280 megawatts of its own clean power by 2017.

Other tech companies, such as Facebook, Google, Microsoft and Intel, include renewable energy in their plans.
