What does a toaster oven have to do with carbon emissions? This week, Melissa and producer Alexandria Herr dissect one to find out. Turns out carbon emissions are embedded in everything around us – from the clothes we wear to our kitchen appliances.  Melissa also talks to energy expert Chris Bataille about what it will take to decarbonize the heavy industries that produce these everyday objects.  Guest: Chris Bataille is an expert on climate and energy policy. He is an associate researcher at the Institute for Sustainable Development and International Relations in Paris (IDDRI) and a lead author on the Industry chapter of the upcoming Intergovernmental Panel on Climate Change Report.  The Big Switch is produced by Columbia University's Center on Global Energy Policy in partnership with Post Script Media.
