Tetra Tech's reported carbon emissions

Tetra Tech, headquartered in the US and operating within the "Other business services (74)" industry, has reported significant progress on its climate commitments. **Emissions Data:** In 2024, Tetra Tech reported total emissions of approximately 76.1 million kg CO2e, comprising Scope 1 emissions of about 10.3 million kg CO2e, Scope 2 emissions of approximately 17.7 million kg CO2e, and Scope 3 emissions totalling around 48 million kg CO2e. The previous year, 2023, saw total emissions of approximately 75.9 million kg CO2e. This included Scope 1 emissions of about 12.5 million kg CO2e, Scope 2 emissions of approximately 22.2 million kg CO2e, and Scope 3 emissions of roughly 41.2 million kg CO2e. For 2022, total emissions were approximately 48.2 million kg CO2e, with Scope 1 at about 9.4 million kg CO2e, Scope 2 at approximately 15.2 million kg CO2e, and Scope 3 at roughly 23.6 million kg CO2e. In 2021, Tetra Tech's total emissions were approximately 44.7 million kg CO2e, consisting of Scope 1 emissions of about 7.3 million kg CO2e, Scope 2 emissions of approximately 22 million kg CO2e, and Scope 3 emissions of roughly 15.4 million kg CO2e. **Climate Commitments and Targets:** Tetra Tech has established ambitious climate targets aligned with global efforts to mitigate climate change. The company has committed to a 50% reduction in absolute Scope 1 and 2 greenhouse gas (GHG) emissions by 2030, using 2021 as the baseline year. This target is consistent with a 1.5°C warming scenario. Furthermore, Tetra Tech has pledged to reduce absolute Scope 3 GHG emissions by 50% within the same timeframe (by 2030 from a 2021 baseline). This comprehensive approach acknowledges the significant impact of value chain emissions. In addition to operational and value chain reductions, Tetra Tech aims to achieve net-zero emissions by 2050. To support these goals, Tetra Tech is also focused on engaging its supply chain. The company commits that 60% of its suppliers, by spend, covering purchased goods and services will have science-based targets by 2027. Tetra Tech's climate commitments are publicly available through various reporting channels, including their sustainability reports and submissions to organisations like the Science Based Targets initiative (SBTi). The company's emissions data and reduction efforts are managed internally, with no indication of data cascading from a parent organisation.
