The White House has mobilized 68 more companies to sign its “American Business Act on Climate Pledge,” in an effort to get U.S. businesses to cut emissions and improve the environment.

The new batch of companies, which include Facebook, Dell, GE, HP, Qualcomm and Intel, join the 13 firms that signed the pledge during the summer. The pledge is a White House-led initiative that commits companies to pushing for a strong climate change agreement at the Paris Climate Summit in late November through early December.

We do believe that business and climate change can go hand-in-hand.

By signing the pledge, the companies are promising to take specific actions to lower their own greenhouse gas emissions. Their promises range from investing in low-carbon forms of energy to making their supply chains — the process by which they create and deliver products — more efficient.
