Greenly is a carbon accounting platform helping SMEs and enterprises measure, reduce, and offset their greenhouse gas emissions with automated data collection and expert guidance.
About
Greenly is a French climate tech company founded in 2019 that has raised over $52M to make carbon accounting accessible to businesses of all sizes. The platform automates greenhouse gas inventory preparation by connecting to accounting software, banking data, and operational systems to collect activity data, then applies emissions factors to calculate Scope 1, 2, and 3 emissions across the full value chain. Greenly targets small and mid-sized businesses that lack dedicated sustainability teams, providing both the software and access to certified carbon experts who guide customers through measurement, reduction planning, and reporting. The company competes with larger enterprise-focused platforms by offering a faster, more automated onboarding experience with expert support that makes carbon accounting achievable for companies with limited resources. Greenly serves over 2,000 customers across Europe and North America spanning retail, hospitality, professional services, and technology. As corporate ESG reporting requirements expand under frameworks including CSRD in Europe and SEC climate disclosure rules in the US, Greenly has positioned itself as the accessible carbon accounting solution for companies beginning their sustainability reporting journey.

About
Constellation Energy Corporation is a Baltimore, Maryland-based clean energy company — publicly traded on NASDAQ (NASDAQ: CEG) as an S&P 500 Utilities component with a market capitalization of approximately $70 billion — operating the United States' largest fleet of carbon-free nuclear power plants with 21 nuclear reactors at 13 generating stations across Illinois, Pennsylvania, Maryland, New Jersey, and New York, through approximately 13,000 employees generating approximately 10% of all clean electricity in the United States. In fiscal year 2024, Constellation Energy reported revenue of $23.6 billion. Constellation was separated from Exelon Corporation in February 2022, when Exelon spun off its power generation business as an independent company while retaining the regulated utility subsidiaries (ComEd, PECO, BGE, Pepco, Delmarva, Atlantic City Electric). CEO Joe Dominguez leads Constellation's strategy of capitalizing on the AI data center electricity demand surge — nuclear power's unique combination of 24/7 carbon-free reliability makes Constellation the preferred clean power supplier for tech companies' 24/7 carbon-free electricity commitments that intermittent wind and solar cannot fulfill. Constellation's landmark achievement was the September 2024 restart of Three Mile Island Unit 1 (renamed Crane Clean Energy Center) — the reactor that operated safely for decades before closing in 2019 due to economic competition from cheap natural gas — under a 20-year power purchase agreement with Microsoft to supply the data center campus supporting Microsoft's Azure AI infrastructure in Pennsylvania.
