New Report Shows Massachusetts as Global Leader in Climatetech With 16 of Top 20 Energy Companies

BOSTON — Governor Maura Healey today highlighted Massachusetts’ continued leadership in the global climatetech economy following the release of a new report identifying the top 20 global companiesleading the energy transition worldwide. The report finds that 16 of those 20 companies have a presence in Massachusetts underscoring the state’s role as a global center for innovation, investment and deployment of clean energy technologies. 



Out of those 16 companies, six specifically have innovation centers, headquarters and regional offices in Massachusetts. That is the most in the nation, tied with California. 



The announcement comes as Massachusetts hosts the annual ClimaTech conference in Boston, bringing together global leaders, innovators, investors and policymakers to accelerate climate solutions and drive economic growth.  



“This report confirms what we’ve been building in Massachusetts – a global hub for climatetech innovation, investment and job creation,” said Governor Maura Healey. “From cutting-edge research to real-world deployment, we are bringing together the companies, workers and ideas that are powering the clean energy transition and lowering costs for residents and businesses. If you want to build, scale and grow in climatetech, Massachusetts is the place to be.” 



The report, released by the Alliance for Climate Transition in partnership with the Dynamic Sustainability Lab at Syracuse University, is the first comprehensive effort to identify and benchmark the global companies driving the energy transition. It highlights companies working across sectors including renewable energy, grid modernization, clean transportation, energy storage and industrial decarbonization. 



Massachusetts stands out as one of the most concentrated hubs for these companies, with a strong presence of global leaders operating innovation centers, regional headquarters, manufacturing facilities and partnerships across the state. 



“As the Iran War makes clear that we need to continue to invest in clean energy technologies to bolster our energy independence and lower energy bills,” said Energy and Environmental Affairs Secretary Rebecca Tepper. “These companies are helping power our communities today and are only expected to grow. As energy demand rises and the need for these technologies increases globally, Massachusetts will be well positioned to capture those new jobs, investment, and innovation.” 



"Massachusetts has long been a magnet for the world's most innovative companies, and this report makes it clear that our climatetech sector is no exception," said Mass Clean Energy Center CEO Ben Downing. "The fact that 16 of the top 20 global energy transition leaders have chosen to put down roots here is a testament to the unmatched talent, research institutions, and innovation ecosystem that our state has built. Massachusetts isn't just participating in the clean energy transition—we're leading it." 



The report finds that 16 of the top 20 companies maintain a presence in Massachusetts through headquarters, regional offices, research facilities, manufacturing or partnerships, including: 




  • Alstom 

  • ABB 

  • BYD 

  • Eaton 

  • Emerson Electric 

  • GE Verona 

  • Hitachi 

  • Iberdrola 

  • Johnson Controls 

  • LG Energy SOolution 

  • Mitsubishi Electric 

  • Rivian 

  • Saint-Gobain 

  • Schneider Electric 

  • Siemens Energy 

  • Tesla 

  • Vestas 



The Healey-Driscoll Administration has made growing this sector a top priority, with a focus on lowering energy costs, strengthening energy independence and creating good-paying jobs. The administration has taken action to accelerate clean energy deployment, invest in workforce training, and support the next generation of climatetech companies through targeted programs, infrastructure investments and economic development initiatives. The report authors specifically point to Governor Healey’s Climatetech Initiative supported by the Mass Leads Act, modeled after Massachusetts’ successful Life Sciences Initiative, as a driving force behind the state’s leadership in this industry. 



These efforts build on Massachusetts’ broader strategy to compete globally by investing in innovation, attracting capital and supporting industries that will define the future economy.
