IDEAS: Let's launch a satellite to track a threatening greenhouse gas

Fred Krupp by TED

When we talk about greenhouse gases, carbon dioxide gets the most attention -- but methane, which often escapes unseen from pipes and wells, has a far greater immediate impact on global warming. Environmentalist Fred Krupp has an idea to fix the problem: launch a satellite that tracks global methane emissions, and openly share the data it collects with the public. Learn more about how simple fixes to cut down on this invisible pollutant can help us put the brakes on climate change. (This ambitious plan is one of the first ideas of The Audacious Project, TED's new initiative to inspire global change.)

Fred Krupp is a leading voice on climate change, energy and sustainability, and a champion for harnessing the power of the marketplace to protect our environment.
