Carbon Checkout is a plug-in software application first launched in 2015, that has since grown into the world's largest carbon offset retail distribution network, now operating in 37 countries. Carbon Checkout and its 2,000+ eCommerce partners, give individuals around the world the convenient option to offset the carbon footprint of any purchase, in one-click at checkout. We aggregate micro-contributions from our global community, and invest directly in renewable energy projects to offset global CO2 emissions. This exchange enables a sizable flow of investment to meaningful projects that would otherwise not be built - showing the power and scale of collective action.
