Environmental Stewardship

We have made the following enhancements to our Sustainability activities:

• In our 2021 Sustainability Report, issued in April 2022, we expanded our roadmap for achieving our stated Scope 1
greenhouse gas (GHG) emissions targets for 2030, increased disclosure about Board of Directors’ governance of our
sustainability efforts, and released new targets for Scope 2 emissions, including a net zero 2050 target. While our Scope 2
emissions are a small component of our GHG footprint, establishing relevant targets is an important part of our sustainability
journey for the future.
• We continued our work during 2022 to reach our 2030 goals for Scope 1 reductions through efficiency projects,
equipment optimization and the rollout of Portland Limestone Cement (PLC) or Type 1L in Texas.

• All necessary local approvals were obtained for a wind turbine project that will supply a significant portion of electrical
energy needed for our quarry in Woodville, Ohio. The new wind turbines will provide an emission-free and renewable
source of energy for the plant going forward.
• Our participation in the recycled aggregates market grew with the acquisitions of recycling assets in Texas, California
and Minnesota in recent years, and we processed and shipped 3.4 million tons of concrete and asphalt generated from
various construction and demolition projects in 2022.
• During 2022, our Chairman and CEO, joined by other senior managers, engaged with an increased number of investors
and others relating to our Sustainability story. This specific outreach in 2022 included detailed phone conversations,
written communications, and in-person meetings with more than 30 investors and groups. In total, we discussed our
sustainability strategy, commitments and achievements with almost all of the approximately 200 investor groups we met
with through personal conversations, virtual conferences, roadshows, field trips, and group meetings during the year.
