Costain has committed to ambitious climate targets. The company aims for net-zero greenhouse gas emissions across its entire value chain by 2050, as validated by the Science Based Targets initiative (SBTi). This commitment includes both near-term and long-term goals.

For near-term reduction, Costain Group PLC commits to reducing absolute Scope 1 and 2 GHG emissions by 42% by 2030, from a 2021 base year. Concurrently, it aims to reduce absolute Scope 3 GHG emissions by 42% within the same timeframe.

For long-term reduction, Costain Group PLC targets a 90% reduction in absolute Scope 1 and 2 GHG emissions by 2050, from a 2021 base year. Similarly, it plans to reduce absolute Scope 3 GHG emissions by 90% by 2050. The company also independently aims to achieve net-zero for Scope 1 and 2 emissions by 2035, and to reduce indirect absolute Scope 3 GHG emissions by 90% to reach net-zero by 2045, both from a 2021 base year. Furthermore, Costain has signed The Climate Pledge, committing to net-zero carbon by 2040.
