28 Massachusetts companies named to Time Magazine’s Top GreenTech Companies

Boston — Today, Governor Maura Healey hosted a celebration of the Massachusetts climate tech industry leaders that were named to TIME Magazine’s Top GreenTech Companies for 2024. All 28 companies, spanning across the state, were recognized with a Governor’s Citation for their contributions to Massachusetts’ economy and competitiveness. Lieutenant Governor Kim Driscoll, Economic Development Secretary Yvonne Hao, Energy and Environmental Affairs Secretary Rebecca Tepper, Massachusetts Clean Energy Center CEO Emily Reichert, and Climate Chief Melissa Hoffer also participated in the celebration.

Governor Healey has aimed to make Massachusetts a global leader in climatetech through a $1 billion investment in her Mass Leads Act. A UMass Donahue Institute analysis found the proposal could generate $16.4 billion in economic activity – representing a 12-to-1 return on investment – and create 6,670 new jobs.

“I’ve had the opportunity to visit many of these climatetech companies over the past few months, and I have been so impressed by the cutting-edge work that they’re doing in communities across the state,” said Governor Healey. “Massachusetts already has the foundation to be the climate innovation hub for the world – innovative incubators and start-ups and unmatched talent. Our administration is putting in the investment necessary to grow this industry to the next level, help these 28 companies continue to grow, and attract new businesses to Massachusetts.”

“We’re thrilled to have the opportunity to congratulate these 28 companies for their leadership in the climatetech industry,” said Lieutenant Governor Driscoll. “They are driving the solutions we need to confront climate change and move toward mitigation, adaptation and resilience – and they’re strengthening our economy while they do it.”

“These companies are proving that climate action is good for business,” said Energy & Environmental Affairs Secretary Rebecca Tepper. “Each of these 28 companies is developing a technology we need to drive down emissions, promote food security and public health, and protect our vulnerable natural resources. Many of these technologies are being piloted right now in Massachusetts, helping us meet our climate goals and creating good-paying jobs along the way. The world is watching Massachusetts and our ingenious entrepreneurs.” 

“Massachusetts has all the right ingredients to become the climatetech innovation hub for the world, starting with the companies and businesses based here in our state that are leading the way with groundbreaking climate solutions,” said Economic Development Secretary Yvonne Hao. “We are grateful for the companies being honored today for their dedication to fighting climate change and strengthening our state’s position as a leader in the green economy.”

“Today, we’re celebrating 28 awesome companies who are showing the world that solving for climate and building a successful business go hand-in-hand,” said Climate Chief Melissa Hoffer. “These are the companies that are building a better world, today – driving climate innovation, creating good-paying climate careers, and helping Massachusetts lead the world in climatetech!” 
“These companies represent the promise of the Commonwealth’s growing climate corridor, a sector that is tackling the climate challenge with technologies that reduce carbon emissions and helping communities and infrastructure adapt to the impacts of climate change,” said Massachusetts Clean Energy Center CEO Dr. Emily Reichert. “MassCEC has supported a majority of these innovators through our emerging technology grants, 2030 Investment Fund, and climatetech internship program.”
