The Greenhouse Gas Inventory provides an overview of the town’s emissions in 2022, benchmarking them against the previous 2018 report. Notable progress was made during that time; Harvard has demonstrated leadership in the adoption of heat pumps, EVs and solar installations. Our tree cover and land preservation plays a significant role in offsetting our emissions but emissions from transportation and housing challenges remain. Scroll down to see our progress through 2025.
