When Covid disrupted the economy and shifted energy use, it sharply brought down economy-wide carbon emissions. Many wondered: would the pandemic-related changes to our energy system help or hurt the path to a net-zero carbon economy? Two years later, we have clearer data: a new report from the Rhodium Group on how emissions from fossil fuels have shifted since the pandemic started. In some cases, they've roared back faster than expected. This week on The Carbon Copy: what the latest emissions data tells us about what has shifted -- and what hasn't -- across America's carbon-dependent economy. Guest: Melissa Lott, Senior Research Scholar at Columbia University and host of The Big Switch.  The Carbon Copy is a co-production of Post Script Media and Canary Media. Support for Carbon Copy comes from Climate Positive, a podcast from Hannon Armstrong, the first U.S. public company solely dedicated to investing in climate solutions.
