Martin Marietta

Martin Marietta, a US-based construction materials company, reported approximately 2.9 billion kg CO2e in Scope 1 emissions and 500 million kg CO2e in Scope 2 emissions for 2024. In 2023, its Scope 1 emissions were approximately 4.295 billion kg CO2e and Scope 2 emissions were around 610 million kg CO2e. For 2022, Scope 1 emissions were approximately 4.609 billion kg CO2e and Scope 2 emissions were around 626 million kg CO2e. In 2021, the company's Scope 1 emissions were approximately 4.547 billion kg CO2e and Scope 2 emissions were about 553 million kg CO2e. In 2020, Scope 1 emissions stood at approximately 4.505 billion kg CO2e, with Scope 2 emissions at about 671 million kg CO2e. Limited Scope 3 data is available, with approximately 211.442 million kg CO2e reported for upstream transportation and distribution in 2017.

Martin Marietta has set several climate commitments, including a near-term intensity target to reduce Scope 1 CO2e process emissions from its heritage cement operations by 15% by 2030, against a 2010 baseline. They also aim for a 30% offset or reduction of Scope 2 CO2e emissions by 2030, using a 2021 baseline. Looking further ahead, the company is committed to achieving net-zero Scope 2 CO2e emissions by 2050, and 100% net-zero Scope 1 and Scope 2 CO2e emissions by the same year. These targets are cascaded from Martin Marietta Materials, Inc. Additionally, Martin Marietta Materials, Inc. has near-term Science Based Targets initiative (SBTi) commitments to reduce absolute Scope 1 and Scope 2 GHG emissions by 63.0% by 2035 from a 2023 base year. They also commit to reducing absolute Scope 3 GHG emissions from purchased goods and services, fuel- and energy-related activities, and upstream transportation and distribution by 37.5% within the same timeframe. These SBTi targets are consistent with reductions required to keep global warming to 1.5°C.
