As of 2025, Martin Marietta Materials has set greenhouse gas (GHG) emissions reduction targets that cover both its operational emissions (Scope 1 and 2) and value chain emissions (Scope 3), offering a comprehensive view of its total carbon footprint.a
As of 2025, Martin Marietta Materials has set a target to reduce its operational greenhouse gas (GHG) emissions, specifically those from Scope 1 and Scope 2 sources.a
Martin Marietta Materials's most ambitious operational target is to reduce these emissions by 23% by 2030, compared to a baseline of 0.846 Metric Tonnes of CO2 equivalent (mtCO2e) per Metric Tonne (mt) of Cement Produced/Manufactured in 2010.a
Martin Marietta Materials has already surpassed its operational emissions reduction target, with 2025 levels falling below the 2030 value, achieving its climate goal ahead of schedule.a
