Climate Lobbying Overview: Martin Marietta Materials (Martin Marietta) appears to have very limited engagement with climate change policy, and InfluenceMap has found limited evidence of corporate disclosures on climate change. However, the company engaged negatively to influence a controversial US policy on science-based environmental rulemaking, which had the potential to prevent effective government regulation on climate change.

Top-line Messaging on Climate Policy: Martin Marietta appears to have limited top-line communications on climate change policy in recent years. In 2017, the company appeared to express ambiguity in its acceptance of climate change on its corporate website, emphasizing the role of natural cycles in causing climate change. In a 2018 letter to the United States Environmental Protection Agency (EPA), the company supported the limitation of what science can be used in EPA rulemaking. This rule had the potential to prevent effective government regulation on climate change by limiting the data that the EPA could utilize to publicly available data, excluding significant amounts of research from various respected institutions across the US. In recent years Martin Marietta does not appear to have taken a clear position regarding the need for climate regulation, the Paris Agreement, and emissions reductions.

Engagement with Climate-Related Regulations: InfluenceMap was unable to find engagement from Martin Marietta regarding specific climate policies in recent years. The company does not appear to disclose its positions toward, or engagement with, climate-related policy on its corporate website.

Positioning on Energy Transition: InfluenceMap has not found evidence of Martin Marietta’s position on, or engagement with, policy related to the transition of the energy mix.

Industry Association Governance: Martin Marietta does not disclose memberships of industry associations on its website. However, the company is a member of two groups that lobby negatively on climate policy, the Portland Cement Association and the US Chamber of Commerce. The company profile for Martin Marietta CEO C. Howard Nye included information that he serves on the board of directors at both groups. Cummins has not reviewed its alignment with its industry associations, as of March 2021.
