Carbon accounting provides a clear framework for assessing a business’s impact, categorising emissions into three areas: Scope 1 (direct emissions), Scope 2 (purchased energy) and Scope 3 (value chain emissions).

Since establishing our carbon baseline in 2020, Sanderson Weatherall has reduced its overall carbon footprint by 31.7%, from 915 tCO₂e to 625 tCO₂e, while continuing to expand the business and grow our service offering. In 2025/26 alone, we achieved a 13% reduction in total emissions while increasing turnover by more than 10%, demonstrating that commercial growth and environmental responsibility are not mutually exclusive.

Transparency is central to our approach. By understanding where emissions occur across our operations and value chain, we can make better-informed decisions, focus our reduction efforts where they have the greatest impact, and track meaningful progress towards our Net Zero 2035 commitment. Below, we provide an open breakdown of our Scope 1, 2 and 3 emissions, the factors influencing performance during the year, and the actions we are taking to continue reducing our environmental impact.
