MARTIN MARIETTA MATERIALS INC is screened out under 2 exclusion reasons spanning 1 issue category.
This page is part of our public exclusion list — a transparency tool that shows which companies we screen out and why. It is not investment advice, and it is not an accusation. It is a statement of values.
Martin Marietta Materials exhibited very limited engagement with climate change policy in 2023-25, taking positions that are broadly unsupportive of climate regulation according to independent assessments. The company’s primary climate commitment is a 2030 science-based target for Scope 1 and 2 emissions, but this excludes its most material emission source: Scope 3 emissions from the downstream use of its cement and aggregates. Cement production, a core business line, is a chemically intensive process that generates significant greenhouse gases. By omitting these value chain emissions, which constitute the largest portion of its carbon footprint, the company’s public climate pledge presents a misleading picture of its full climate impact. This pattern aligns with broader industry findings where major corporations use incomplete or ambiguous climate claims.
Martin Marietta Materials Inc. agreed to pay a $2.4 million penalty and invest approximately $4 million in pollution controls to settle Clean Air Act violations at its facilities in 14 states.

The Naughty List
A digest of changes to our exclusion list — new additions, removals, and the evidence behind them. We review the list continuously as new evidence surfaces.
Companies appear on our exclusion list based on our investment judgment — not because they've done anything illegal. This is a difference of values and opinion, not an accusation of wrongdoing. Exclusion does not constitute a recommendation against investing in any company, and absence from the list does not constitute a recommendation to invest.
