The Mapbox garage in Washington, DC is 100% powered by renewable wind energy – an average of 3,600 kilowatt hours per month of clean power from Clearview Energy. Those wind farms you see in our satellite imagery? Yeah, they're keeping the lights on.
In San Francisco, we've pre-enrolled in the SF Public Utility Commission's CleanPowerSF initiative. Until we can power the office with renewables, we're buying RECs from TerraPass that are Green-e certified, as recommended by the Natural Resources Defense Council.
Because our team is global, we also fly a lot for events and project sprints. Every flight has huge environmental costs – flying one team member from Washington, DC to San Francisco generates 0.62 tons of CO2, according to the International Civil Aviation Organization. We've offset our flights stretching back to January 1, 2014 with Climate Action Reserve and Verified Carbon Standard carbon offsets, which fund afforestation in California, landfill methane capture in Maryland, and waste-to-energy projects on Michigan farms. In 2015, we offset a total of 104.6 tons of CO2 from air travel.
