Carbon Credits and RECs are essential climate tools with distinct roles. Carbon Credits, issued by registries like Verra, represent one metric ton of CO2e reduced, offsetting unavoidable emissions through projects like reforestation. RECs, issued by systems like Green-e, certify one MWh of renewable electricity, promoting clean energy markets. Companies use Credits to offset emissions (e.g., travel) and RECs to claim renewable energy usage (e.g., office electricity). While Credits directly cut emissions, RECs support renewable growth. Combining both helps firms meet net-zero goals, balancing direct reductions with clean energy adoption for broader impact.

Carbon credits are vital for tackling climate change, representing one metric ton of CO2 reduced or removed. They enable businesses to offset unavoidable emissions by supporting projects like reforestation or renewable energy. Compliance markets, like the EU ETS, drive industrial emission cuts (47% since 2005), while voluntary markets help companies like Microsoft achieve carbon negativity. Buyers include corporations, governments, and airlines; sellers are project developers. Standards like Verra ensure credit quality through rigorous verification. Despite criticisms of over-reliance, credits complement decarbonization, with global markets expanding via initiatives like CORSIA and Paris Agreement’s Article 6, fostering innovation and sustainability.
