Summit Materials's reported carbon emissions
In 2023, Summit Materials reported total carbon emissions of approximately 2,010,000,000 kg CO2e. This figure includes about 1,730,000,000 kg CO2e from Scope 1 emissions and approximately 280,000,000 kg CO2e from Scope 2 emissions. The combined Scope 1 and 2 emissions totalled 2,010,000,000 kg CO2e, reflecting the company's ongoing operational impact on climate change. Summit Materials has set ambitious reduction targets for its emissions intensity. By 2030, the company aims to achieve a cement emissions intensity of 0.65 metric tons CO2e per metric ton produced, representing a 25% reduction from its 2020 baseline. Furthermore, the long-term goal is to reach an intensity of 0.25 metric tons CO2e per metric ton produced by 2050, which would require a 50% reduction, with offsets to achieve net-zero emissions. In alignment with broader climate commitments, the United States has pledged to reduce greenhouse gas emissions by 50-52% by 2030 under the Paris Agreement, which Summit Materials supports through its own reduction initiatives. The company has not disclosed Scope 3 emissions data, indicating a focus on direct and indirect emissions from its operations.
