Climate Lobbying Overview: Martin Marietta Materials (Martin Marietta) appears to have limited transparent engagement with climate change policy. However, the company retains board membership of several key industry associations which are engaging negatively on US climate policy.

Top-line Messaging on Climate Policy: Martin Marietta appears to have limited top-line communications on climate change policy between the years 2018 and 2022. The company does not appear to take positions on the need for climate regulation, the UN Paris Agreement, nor long-term emissions reductions.

Engagement with Climate-Related Regulations: Martin Marietta appears to have had limited transparent engagement with specific climate policies since 2018. The company stated in its 2020 Sustainability Report, published in 2021, that it does not engage on climate policy.

Positioning on Energy Transition: Martin Marietta appears to have limited engagement with policy related to the transition of the energy mix, although taking negative positions on a range of issues. In its 2020 Sustainability Report, published in 2021, the company advocated for the removal of regulatory constraints on alternative fuels, without defining what this includes, and for policies to support Carbon Capture and Storage. It described its position on technologies needed to reduce emissions in the cement sector in broad terms, without elaborating on specific policies or describing engagement activities. In a press release, published in March 2022, Martin Marietta supported the Mountaineer Xpress Pipeline in West Virginia, a fossil gas pipeline which will lock in unabated fossil fuels, including fossil gas.

Industry Association Governance: Martin Marietta disclosed membership of industry associations in its 2021 Sustainability Report, describing the associations’ positions and how it is attempting to influence them. However, it did not disclose the engagement activities of the associations, nor has it published a review of alignment with associations. The company is a member of two US groups that lobby negatively on climate policy, the Portland Cement Association, in which a senior executive is on the board, and the US Chamber of Commerce, in which the CEO is on the board of directors.
