Greentown Boston
At Greentown Labs we partner with TripZero to provide attendee-only hotel deals and mitigate the carbon footprint created by travel to the Climatetech Summit.
The average attendee will create almost 400 pounds of CO2 in transit. We'll offset all of it with Certified Carbon Offsets.
Your booking enables us to offset your travel footprint through the purchase of Certified Carbon Offsets (at no cost to you).
These offset purchases finance amazing renewable energy, methane reduction and forestry projects that remove CO2 from the atmosphere. In turn, they render your trip carbon-neutral and benefit local communities.
