What's next for the U.S. after the Paris climate agreement?

Well before the final negotiations of the COP21 climate talks in Paris, business was already making a big difference on the ground. For the first time, superstar entrepreneurs showed up with plans to fund major initiatives. Giant companies sent CEOs to showcase their results in reducing carbon in their own operations. And entire industries, such as financial services, agriculture and manufacturing, made new commitments to address climate change.

Attending the talks as a business leader, I could tell that positive pressure from the business sector was going to lead to success. The overwhelming message to government leaders was, “we, the international business community, will support you if you make a strong deal.”

But of course talk is cheap — and easy. Now comes the difficult part: turning the agreement into actions that will actually save the planet.

Luckily, business excels at innovating and turning plans – no matter how vague – into practical, achievable results. And American businesses are arguably the best in the world at that.

First, and easiest, is for companies to make or extend individual commitments to reduce carbon. Whether by increasing their usage of renewable energy or energy efficiency, streamlining supply chains – or even steps as small as offering mass transit incentives to employees – companies large and small can take their own steps to cut carbon emissions.

Over and over in Paris, we heard how these efforts actually strengthen the bottom line. We saw many businesses that are committed to doing their part on climate change – like Patagonia, which has installed nearly 500 solar panels at its headquarters.

But as great as the voluntary efforts are, no one believes they will be enough to reach the necessary targets. For significant progress, business needs government to nudge things in the right direction.

For example, take the Clean Power Plan, the EPA’s rules to reduce carbon emissions from power plants. These rules will significantly cut our greenhouse gases, which is a major benefit for every industry. The rules provide states with unprecedented leeway in crafting their own plans, which will result in technological innovation and job creation.

Unfortunately, some in Congress are trying to block the rules as being bad for business. That’s why during the Paris summit, our business group joined with Environmental Entrepreneurs (E2) to announce letters calling on Congress not to derail the talks and get serious about strengthening America’s economy.

Most small business owners agree with us. National, scientific polling found that 64 percent of small business owners support government regulation to cut carbon pollution from power plants.

In fact, many business people want even stronger climate policies, such as carbon pricing.

Major U.S. brands like Ben & Jerry’s and Seventh Generation support putting a market price on carbon. Many more U.S. companies are signing a business letter to Congress showing support for a carbon tax. Internationally, even oil companies are getting behind the idea.

When I was in Paris, I spoke with an executive of a giant European oil company. As she explained, a carbon tax “provides us with a clearer path for making mid-term investment decisions. Whether we invest in another oil field, or move toward more wind depends in large part on what the price of CO2 will be.” This is using the power of the market to determine how to power the economy going forward.

The Paris climate talks resulted in a breakthrough agreement. But it is really just the beginning. Now we all – individuals, government and businesses – need to do everything we can to turn that talk into action. For business leaders, that means not only doing what we can in our business, but it means pushing our elected officials to do what they need to. Paris proved that business support can help in making a deal. To turn that deal into reality, business support will be essential.
