Following the money on climate action

Bill Gates and Mark Zuckerberg made headlines this week when they announced a new billion-dollar clean energy fund, which comes in the wake of several other 12-figure green energy commitments by Wall Street Banks. Despite the many public announcements, government delegates from developing countries continue to express concerns about a dearth of international funding for climate adaptation.

Prime time for public-private partnerships

One way the road to Paris has been differed from past climate summits is the emphasis on bringing corporations into the process. The issue: A continued lack of international clarity on issues like carbon pricing continues to hamstring businesses and regulators alike.

Featured stories

An in-depth look at two stories changing the game for green business.

Climate innovation

Senior Writer Barbara Grady recently headed across San Francisco Bay for a summit on social innovation, including unconventional ways for putting unused capacity to work for social good.  The verdict? Creative financing to draw funds to environmental conservation and using social media and design thinking to gather talent and ideas for problems that need solving. 

Meg Garlinghouse of Linkedin for Good, Sarah Heard from the Nature Conservancy and Jason Rissman of OpenIDEO all spoke about their contributions to the field.

The materials matchmaker

How do you get businesses to act on the ideals of the circular economy? One answer: corporate materials marketplaces.
