Climate Change Lobbying

Given our businesses’ relatively low GHG emissions profile, Martin Marietta does not conduct, at the federal or state level,
any direct lobbying on climate change. We are a member of only three national trade associations (two of which
represent the aggregates and ready mix industries) in addition to the U.S. Chamber of Commerce. We periodically review
lobbying registrations submitted by these associations, and do not believe that any have taken any position as part of its
lobbying efforts that is inconsistent with the Paris Agreement.

• The Portland Cement Association (PCA), a major industry • The U.S. Chamber of Commerce, which represents U.S.
group for U.S. cement manufacturers (and the only businesses across all sectors, has stated since 2019 its
cement industry association in which we are a member), support for U.S. participation in the Paris Agreement as
recently announced its commitment to helping its well as its position that our climate is changing, that
member companies achieve carbon neutrality across the humans are contributing to these changes and that
value chain by 2050. To this end, the PCA expects to mitigating GHG emissions, increasing fuel efficiency and
adopt and publish its own roadmap to carbon neutrality use of renewable fuels and investing in commercially-
later this year. viable technological solutions for lower-carbon
infrastructure and carbon capture or storage, are
essential for managing climate risks.

As recognized by a number of international organizations (including the International Energy Agency) as well as various
industry associations, the cement sector’s ability to contribute to limiting GHG levels in a manner consistent with the goals
of the Paris Agreement depends on successful future development and implementation of carbon capture and
sequestration (CCS) technologies on a commercial scale. Similarly, acceptance of lower clinker content cements by
Departments of Transportation and ASTM in the United States will also be critical in allowing the cement sector to achieve
carbon neutrality across the value chain by 2050. We are monitoring these developments closely.
