Goals

Driving Toward a Better Future for Everyone

As part of our commitment to corporate sustainability and environmental stewardship, we have set ambitious sustainability targets for 2030 and 2050, including a path toward net zero emissions by 2050. We believe that not only are these goals achievable, but they are vital for protecting the people and the environment in the communities where we work.

Near-term Priorities

Increasing alternative fuel usage and fuel efficiency
Water metering and conservation
Front line employee development
Environmental product declarations
Embodied concrete and methane capture

Long-term Opportunities

Increasing alternative fuel usage and fuel efficiency
Standardized reclamation plans
Exploring pilots for carbon capture and storage
100% closed loop water systems across the business
Renewable power agreements with utility partners

We strive to meet and exceed these goals by setting our sights firmly on a better future for our company, our communities and our planet.

Carbon Reduction

Customers and investors have set a goal: attaining a lower carbon future is not an aspiration, it’s a necessity. That is why we have made it a priority to achieve net zero carbon emissions by 2050.

We aim to ensure that Summit is a leader in our industry’s decarbonization efforts through product and operational innovation. We believe that with currently available technologies, approximately 25% of our 2020 baseline impacts can be addressed by 2030, and 50-75% of those impacts can be addressed by 2050. As an interim step, we plan to address the balance of those impacts with market-based offsets and credits in order to achieve net zero emissions.
