2.1 An industry is composed of eight firms. The CEOs of these firms realize that their industry creates air pollution and contributes to climate change. Dismayed at this thought, they meet and decide to do something about it. But reducing pollution is expensive, so the CEOs agree to boost their prices by 2 percent and use the extra revenue to combat their pollution. All of the CEOs abide by this agreement and significantly decrease their contributions to air pollution.

Would this agreement violate the Sherman Act?

Why or why not?
