Martin Marietta's Climate Commitments and Emissions Data

In its 2024 reporting year, Martin Marietta, a US-based company in the construction materials industry, reported Scope 1 emissions of approximately 2,900,000,000 kg CO2e and Scope 2 emissions of approximately 500,000,000 kg CO2e, totaling approximately 3,400,000,000 kg CO2e for these scopes. This contrasts with 2023, when Scope 1 emissions were approximately 4,295,000,000 kg CO2e and Scope 2 emissions were around 610,000,000 kg CO2e. In 2022, the company reported Scope 1 emissions of approximately 4,609,000,000 kg CO2e and Scope 2 emissions of approximately 626,000,000 kg CO2e. Prior to this, in 2021, Scope 1 emissions stood at approximately 4,547,000,000 kg CO2e with Scope 2 emissions at approximately 553,000,000 kg CO2e. In 2020, Scope 1 emissions were reported as approximately 4,505,000,000 kg CO2e, and Scope 2 emissions were approximately 671,000,000 kg CO2e.

Martin Marietta is actively pursuing climate mitigation strategies. The company has set a near-term target to reduce the intensity of its Scope 1 CO2e process emissions from cement operations by 15% by 2030, using 2010 as a baseline. Additionally, there is a commitment to offset or reduce Scope 2 CO2e emissions by 30% by 2030, relative to a 2021 baseline. For the long term, Martin Marietta aims for net-zero Scope 2 CO2e emissions by 2050, and intends for 100% of its Scope 1 and Scope 2 CO2e emissions to be net-zero by 2050.

More recently, through the Science Based Targets initiative (SBTi), Martin Marietta Materials, Inc. has committed to reducing absolute Scope 1 and 2 GHG emissions by 63.0% by 2035, based on a 2023 baseline. This also includes a commitment to reduce 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 considered to be consistent with limiting warming to 1.5°C.

While Scope 3 emissions data is not extensively detailed for all reporting years, there is a recorded Scope 3 emission value of 211,442,000 kg CO2e for upstream transportation and distribution in 2017. Data for 2019 and 2018 does not show disclosed emissions figures.

Martin Marietta's climate commitments and targets are established in line with its overall corporate sustainability strategy. The company operates within the construction materials sector, which is recognised for its material contribution to global greenhouse gas emissions.
