Greentown LabsESG & Sustainability Jobs

Nonprofit climatetech incubator with labs in Boston and Houston supporting startups across energy, buildings, agriculture, and transportation

Greentown Labs is a 501(c)(3) nonprofit that runs physical incubator spaces in Somerville, MA and Houston, TX for climatetech startups. Member companies work across sectors including electricity, buildings, agriculture, manufacturing, transportation, and resiliency. Greentown provides lab and office space, a peer network, mentorship, and connections to corporate partners and investors.

Why it matters

The organization's model is built on the idea that climatetech commercialization requires a full ecosystem - founders, corporations, capital, and policy - working together. By co-locating startups and facilitating structured engagement with industry partners and investors, Greentown aims to accelerate the path from prototype to deployed product. Its stated mission ties climate impact directly to economic outcomes: more clean energy, cleaner air, and job creation in the climatetech sector.

With two campuses and a membership spanning multiple climatetech verticals, Greentown operates as a hub for early- and growth-stage companies trying to move hardware and software climate solutions out of the lab and into commercial use.

How this is measured

We fetch every open role a company publishes and classify each one with an automated keyword-and-context filter. Roles that match sustainability, climate, environmental, or governance criteria are kept and counted as active; the rest are filtered out. This is one transparent signal of how much of a company's current hiring is sustainability-focused - it is not a verdict on the company, and it reflects only public job postings we have tracked, not the company's full operations.

The classifier is automated and imperfect: it can occasionally mis-classify an individual role, so treat small differences as noise. We only show this signal when we have screened enough roles for the numbers to be meaningful.
