In total, attendee and staff travel accounted for 99.9% of the GWC’s carbon footprint of 74 metric tons. GWC and STOKE searched all over the globe for third-party verified ‘blue carbon’ offsets (carbon sequestration in coastal ecosystems—seagrass, mangroves, etc.), which was an exciting frontier discussed at the conference. However, the two blue carbon projects we did find had no more credits for 2018 and the rest of the market still has another year to mature. Instead, GWC decided to direct attendees to purchase offsets that support reforestation and restoration work in coastal watersheds close to the event at one of The Conservation Fund’s three projects in Northern California. GWC hopes to find a verified blue carbon offset project for the 2020 event.
