The environmental movement has made something clear: For the health of the planet, humans need to stop using so much fossil fuel. Period. Many efforts to reduce fossil fuel use focus on consumer behavior — CAFE standards, electric vehicle subsidies, and the like are designed to lessen demand for these polluting fuels. Meanwhile, billions upon billions of dollars are being invested right now in new fossil fuel extraction projects across the globe. This week on Sea Change Radio, we speak with one of the environmental leaders working to stem the supply side of the equation. Today we are speaking with Tzeporah Berman of Stand.earth, and the Fossil Fuel Nonproliferation Treaty Initiative, about the work she and her colleagues are doing to keep fossil fuels in the ground. We examine the current state of pipeline projects in North America, discuss how fossil fuel companies are dealing with slimming profit margins, and look at how changing market realities are affecting the business.
