The company provides an integrated software solution for corporate carbon accounting, ESG reporting, and net-zero planning, serving over 200 companies predominantly in the DACH region and broader Europe. Plan A was one of the early European entrants in the corporate sustainability software market.\n\nThe platform covers the full ESG lifecycle, from data collection and carbon footprint calculation to materiality assessments, ESG scoring, and regulatory report generation. Plan A supports multiple reporting frameworks including GHG Protocol, CDP, GRI, and the EU taxonomy. Its module for double materiality assessment is particularly relevant for companies navigating the CSRD requirements that mandate identifying both financial and impact materiality.\n\nPlan A targets mid-size to large enterprises in Europe that need a comprehensive ESG platform rather than a point solution. It competes with Greenly, Normative, and Sweep in the European market. The company differentiates through its breadth of ESG coverage beyond just carbon, its consultancy network of sustainability experts, and its early mover advantage in the EU regulatory compliance space.

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.
