The Energy, Sustainability, and Environmental practice at C&V is extensive, and has grown significantly since the firm’s founding. Members of the Constantinople & Vallone team have been featured in City & State’s “Energy and Environment Power 100” list in 2020, 2021, 2022, and 2023, and named among the “Trailblazers for Clean Energy” in 2024 and 2025. Members of our team currently serve on both the Statewide and New York City Boards of the League of Conservation Voters.
