Home is Where the Pipeline Ends

New research by HEET, Harvard, and PSE Health Energy finds chemical contamination in natural gas delivered to homes. Read the study here. Researchers took natural gas samples from kitchen stoves across Greater Boston. In 2015, a natural gas storage facility near…

New Maps: Gas Leaks & Plans for New Gas Pipes in MA 

HEET started mapping gas leaks in 2015, making the magnitude of leaks in our streets visible and accessible to the general public for the first time. Now, we are excited to share an improved format of our annual gas leak…

Gas Leaks at Massachusetts School Properties

Our new report with UndauntedK12 provides the first statewide analysis of gas leaks reported at school properties. There were 91 reported gas leaks at MA schools in 2021 alone. A third of those required immediate attention by utility workers.  Importantly,…

What is the Future of Gas?

This year has been a critical time to consider the future of gas - or the lack of a future for gas! Climate laws across the country are driving states to drastically reduce emissions. To actually achieve those reductions, we…

Energy Efficiency Tip with Jason Taylor

At HEET, we’re all about systems change–and direct carbon-cutting steps are an important part of that process. HEET’s Jason Taylor is here to share some of his extensive knowledge on energy efficiency and simple steps you can take right now…

Six GeoMicroDistrict demos approved for Massachusetts!

As The Boston Globe recently reported, Eversource Gas and National Grid Gas, the two largest utilities in Massachusetts, have both received approval to install demonstration projects using HEET’s GeoMicroDistrict model: non-emitting systems of networked ground source heat pumps.  The Mass. Attorney…

“We’re Aligned 100% With HEET”

Watch Bill Akley, president of Eversource Energy’s gas business unit, announce the GeoMicroDistrict pilots.

Gushing Natural Gas Leaks

Just 7% of natural gas leaks emit fully half of all the methane emissions from Massachusetts’ aging gas distribution system. Methane is a potent greenhouse gas. Fixing these leaks is critical to reducing our emissions.

Large Volume Leak Study

HEET worked with National Grid, Eversource and Columbia Gas to scientifically prove how to identify the largest gas leaks so they can be fixed.

Common Goals, Uncommon Partners

At an MIT summit, HEET and three gas companies announced a plan to fix the largest gas leaks. The plan includes independent verification, data transparency and annual reassessment.

Maura Healey Thanks HEET

Mass. Attorney General Maura Healey thanks HEET for its work to find a way to reduce methane emissions both in this state and nationally.
