Martin Marietta aims at reducing its scope 1 emissions by 15% for its cement operations and by 10% for its magnesia specialties business by 2030 compared to 2010. The company has recently set a target for net-zero scope 1 and 2 emissions by 2050. Regardless, the emissions intensity trend of Martin Marietta’s cement production decreased by less than 1% per year between 2019 and 2022. The company does not report emissions data for earlier years.

Martin Marietta has linked incentives for various board-level positions with long-term climate-related targets by establishing key performance indicators. Additionally, the company has completed scenario analysis to test its low-carbon transition plan, but it can strengthen its analysis by including a 1.5°C scenario. There is no evidence that the company has obtained significant results as yet from creating or expanding low-carbon business models or implementing actions to decarbonise activities within its existing business models.

Martin Marietta has invested in tyre handling systems for its Midlothian and Hunter Cement plants, for which tyres represented 25% of energy consumption in 2022. The company’s disclosures, however, do not allow for estimating the current share of alternative fuels it uses to replace coal as an energy source to produce clinker. Moreover, the company does not disclose its research and development (R&D) expenditure in the last three years, nor does it provide quantitative data on its investment in low-carbon technologies.

Martin Marietta does not publicly disclose strategies for engaging suppliers and clients to promote emissions reduction and the low-carbon transition. No evidence was found to indicate that the company opposes climate-aligned policies. However, Martin Marietta can increase its credibility by publicly publishing and demonstrating its support for climate policies, such as the Paris Agreement.

The emissions reduction targets set by the company for 2030 are lacking in ambition. The company also does not mention the extent to which it will rely on carbon offsets to reach its 2050 net-zero scope 1 and 2 emissions target.

There is a huge gap between the company’s short-term emissions reduction ambition up to 2030 and long-term ambition up to 2050. This casts doubt on Martin Marietta’s motivation to quickly and significantly decarbonise its activities.

Martin Marietta has not been able to significantly reduce the emissions intensity of its cement production in the last three years. The choice to set targets against the distant base year 2010 also calls into question the company’s ambition regarding its low-carbon strategy.

Martin Marietta has partially replaced coal with alternative fuels to produce clinker and is progressively replacing its Portland cement with lower emissive Portland-limestone cement (PLC). The company has also implemented some actions to lower emissions from some of its operations, such as transportation.

The company discloses limited information regarding future actions and plans and instead focuses on past and current performance. Without financial disclosure of its planned investments and the expected contributions of its emissions reduction actions, Martin Marietta’s transition roadmap lacks robustness.

No evidence was found of the company’s commitment to social dialogue or of the categories of stakeholders the company engages with on a just transition. Furthermore, no evidence was found to demonstrate the company’s ongoing social dialogue and meaningful engagement with affected stakeholders.
No evidence was found of the company undertaking low-carbon transition planning to mitigate the social impacts of the transition on workers, affected stakeholders and its business relationships. Additionally, no evidence was found to demonstrate the company’s engagement in social dialogue and with stakeholders in its just transition planning.

No public commitment by the company was found stating its intention to create and support access to green and decent jobs as part of the low-carbon transition. Moreover, no evidence was found of the company’s action to promote these jobs in a way that ensures gender balance and inclusion of vulnerable groups.
No relevant disclosure was found of the company’s assessment of employment dislocation risks. Moreover, no public commitment by the company was found stating its intention to reskill and upskill workers displaced by the transition to a low-carbon economy. Additionally, no evidence was found that the company reskills and upskills workers in a way that ensures gender balance and inclusion of vulnerable groups.

The company contributes to closing the social protection gap for affected stakeholders by offering a scholarship programme for the residents of Woodville, Ohio where it is changing its business to reduce carbon emissions and installing new wind power. However, no other relevant disclosure was found to show if the company works to identify the impacts of the low-carbon transition on social protection for workers and affected stakeholders.
No relevant disclosure was found to show how the company identifies any misalignment of its lobbying activities with policies and regulations that support the just transition, nor of the measures it takes to address misalignment. Furthermore, no evidence was found that the company lobbies for policies and regulations for green and decent job creation; retention, education and reskilling; and social protection for workers.

The company has a grievance mechanism for human rights related issues available to workers and external stakeholders. However, no other company policies or commitments related to respect for human rights were found in the public domain. This includes the necessary policies and systems by which the company can ensure respect for basic human rights in its operations and supply chain.

The company commits to respecting the health and safety of its workers and expects the same commitment from its business relationships. Additionally, the company discloses statistics on the gender of its workforce by employee category. However, the company can strengthen its disclosure on these subjects as well as on other key decent work issues, such as collective bargaining, living wages and working hours.

The company has a policy prohibiting bribery and corruption, and it includes corresponding clauses in its business relationship contracts. Additionally, the company has a public commitment to protect personal data. However, the company can strengthen its disclosure on these and other key ethical business topics, such as lobbying, political engagement and responsible tax practices.
