Working for a Better Tomorrow

At Martin Marietta, our pillars of sustainability – safe operations, environmental stewardship, employee well-being and community well-being – guide all that we do.

Our Sustainability Approach

Rooted in our core values and a commitment to being responsible stewards of our natural resources, our sustainability approach allows us to create lasting results that benefit our people, customers and communities.

Safe Operations

Safe Operations

Safety is foundational to how we operate.

At Martin Marietta, it guides every decision, from daily work at our facilities to oversight at the Board level, and shapes a culture where protecting people comes first.

How we put this into practice:

Safety is our first company value and the first agenda item in meetings at every level of the organization.

Every employee is empowered to stop work and address unsafe conditions without fear of repercussion.

Oversight is reinforced through Board-level governance and a dedicated safety leadership structure.
