Managing our Climate Impacts


As industry leaders, we are committed to operating our businesses in a socially responsible and sustainable manner. Our company policies guide our clean energy and climate strategy and reinforce our commitment to support meaningful climate action, within our own operations and beyond.

Constellation's climate goals were developed with consideration of Constellation's fleet and customers only. Given the transaction with Calpine, Constellation will necessarily re-evaluate its climate goals based on the combined company's portfolio. What's not changing is that we remain a company focused on sustainability and providing customers and our nation with the most important commodity in the world today – energy that is clean and reliable.
