Summit Materials

Summit Materials, a US-based construction materials company, has reported its carbon emissions for recent years. In 2023, the company's Scope 1 emissions were approximately 1,730,000,000 kg CO2e, and its Scope 2 emissions were about 280,000,000 kg CO2e. This marks a decrease from 2022, when Scope 1 emissions stood at approximately 1,870,000,000 kg CO2e and Scope 2 emissions at 260,000,000 kg CO2e. In 2021, Scope 1 emissions were reported as 1,890,000,000 kg CO2e and Scope 2 emissions as 310,000,000 kg CO2e. For 2020, Scope 1 emissions were approximately 1,960,000,000 kg CO2e, with Scope 2 emissions at 230,000,000 kg CO2e.

Summit Materials has set climate commitments, aiming for an absolute reduction of approximately 25% of its 2020 baseline impacts by 2030 across Scope 1 and Scope 2 emissions. Additionally, the company has set an intensity target for its cement production, aiming for a cement emissions intensity of 0.65 metric tons CO2e per metric ton produced by 2030. Looking further ahead, Summit Materials has a long-term target of 0.25 metric tons CO2e per metric ton produced for cement emissions intensity by 2050, with offsets to achieve net-zero.

It's important to note that the emissions data reported by Summit Materials are inherited from Summit Materials, Inc., its parent organisation, at cascade level 1. Scope 3 emissions data are not currently disclosed.
