Constellation Energy Corporation (CEG) — ESG & Values Scores

Environment story

Constellation operates the largest emissions-free (nuclear-heavy) generation fleet in the U.S., with ~68% of electric supply from nuclear and 2% from renewables, and is investing in physical decarbonization infrastructure (Crane Clean Energy Center restart, Calpine geothermal/battery storage, and CCS R&D). However, Scope 3 (product-use / supply-chain) emissions are not disclosed, no explicit net-zero target year was found in filings, and the Calpine acquisition materially increases the natural-gas-fired share of the fleet. A historical water/habitat controversy at the Conowingo hydroelectric facility (FERC license vacated, subsequent settlement with state regulators and riverkeeper groups) also weighs on the score.

Criticisms on file

Conowingo Hydroelectric Project license dispute — FERC's 2021 50-year license was vacated in December 2022 amid environmental/water-quality concerns; a September 2025 settlement with the Maryland Department of the Environment, Lower Susquehanna Riverkeeper Association, and Waterkeepers Chesapeake allowed resubmission of the license application.

Disclosed initiatives

Crane Clean Energy Center Restart (former Three Mile Island Unit 1)

20-year PPA with Microsoft to restart a retired 835 MW emissions-free nuclear unit; DOE Office of Energy Dominance Financing issued a guarantee for up to $1.0B loan to support the restart.

Adds ~835 MW of physical zero-emissions generating capacity, not offset-based.
Calpine Geothermal & Battery Storage Integration

Acquisition added the Geysers Assets (largest U.S. geothermal portfolio, ~730 MW) and ~800 MW of battery storage, largely in California.

Physical low-carbon and storage infrastructure expansion.
Carbon Capture and Sequestration (CCS) Development

Calpine is cited as developing CCS technology aimed at decarbonizing natural gas generation.

Potential future reduction of direct operational emissions from gas fleet (not yet operational at scale).

Social story

Constellation discloses a perfect (100) HRC Corporate Equality Index score and maintains nine employee resource groups across 67 chapters with over 5,000 participants, alongside stated pay-equity analysis practices. CEO-to-median-worker pay ratio, workforce diversity percentages, and turnover rates were not disclosed in the reviewed filings. A 2026 shareholder proposal from a conservative advocacy group challenged the company's DEI programs as posing litigation/reputational risk; the Board recommended voting against it. Nuclear fuel procurement includes contracts sourced from Russia, a supply-chain sourcing point of geopolitical/human-rights scrutiny not fully detailed in the filings.

Criticisms on file

Governance story

Constellation maintains strong structural governance: 11 of 12 directors are independent (all except the CEO), all Board committees are 100% independent, the Board is fully declassifying after the 2026 Annual Meeting, and executive compensation practices include clawbacks, no hedging/pledging, and no excise-tax gross-ups. No dual-class share structure, antitrust actions, consumer-safety fines, or SEC consent decrees were identified in the reviewed filings. Lobbying expenditure figures were not disclosed. A contested 2026 shareholder proposal on DEI oversight (opposed by the Board) and the historical Conowingo license controversy represent the primary governance friction points identified.

Criticisms on file

Conowingo Hydroelectric Project's FERC license was vacated in 2022, requiring multi-year regulatory settlement negotiations with state and environmental groups.
