Columbia Business School’s Professor Gernot Wagner spoke with Washington Post climate reporter Michael Coren about practical home improvements that can significantly reduce carbon emissions. Wagner highlighted the climate benefits of upgrades such as heat pumps, induction stoves, improved insulation, and rooftop solar, noting that these investments not only cut emissions but also lower long-term household energy costs. He emphasized that decarbonizing homes is a critical piece of broader climate action, especially as residential energy use accounts for a substantial share of emissions.
