Carbon credits are tradable certificates entitling the bearer to emit one metric ton of carbon dioxide or its equivalent. In 2018, 98.4 million metric tons of CO2 (MgCO2) were marketed for a value to the seller of $296 million. A third of those credits were generated by a program called Reducing Emissions from Deforestation and Degradation (REDD+). Does this market solution reduce our carbon footprint, or are we looking at something Bernie Madoff or Sam Bankman-Fried might be offering?
