ELLISON: Everyone assumes the United States lags the rest of the world in cutting emissions. True? SANDOR: Europe’s not as far ahead as people think and America’s not as far behind … Our baseline is 550 million tons, Europe’s is 2 billion, so actually we’re 25 percent the size of Europe.

How can you be sure that companies are cutting emissions? I called the Financial Industry Regulatory Association and said, “You’re going to be really surprised. I want you to regulate us.” [They] do spot audits.

Will there eventually be a global, regulated market? In the absence of a federal policy, we invent a policy. In Canada, we’ll do what the Canadians want. In India, we will cater it to Indian culture. Even though it’s a global problem, you’ve got to let each country set its own standards. You can’t let the perfect be the enemy of the good.
