The current reporting period is 1 January to 31 December 2022, which is aligned to the Group financial year. This is compared against a fixed base year, which is selected as 1 January to 31 December 2021. The 2021 base year is selected as this is the earliest year that a complete scope 1, 2 and 3 GHG inventory is available. The base year has been adjusted to include full annual emissions of the acquisitions DB Group (Europe) Limited (joined February 2022) and Powerful Allies (joined June 2022) in accordance with our base year recalculation policy.

Total gross location-based and marketbased emissions have increased 21% and 25% respectively this year. This compares to an increase in the employee intensity ratio of 5% and 8% for location-based and market-based emissions respectively. The relatively small increase in employee intensity ratios reveals that some of the gross emission increase correlates to an increase in employee numbers. The largest contributions to increases in emissions is scope 3 business travel and employee commuting, resulting in an increase of 119.2 tCO₂e (136%) and 98.9 tCO₂e (107%) respectively. This is to be expected as business operations pick up again following the COVID-19 pandemic and employees return to the office. Nevertheless, homeworking remains at levels much higher than pre-pandemic.

The largest contributions to reductions in scope 3 emissions is purchased goods and services and capital goods, resulting in a decrease of 75 tCO₂e (35%) and 42.5 tCO₂e (46%) respectively. Electricity energy consumption (kWh) has increased 5% this year. Due to a lower electricity emission factor, this translates to a 3% decrease in scope 2 location-based emissions. Scope 2 market-based emissions are influenced by contractual emission factors that are more volatile, meaning these emissions have increased 65%. This is predominantly due to the Brierley Hill office, which has increased electricity usage as well as a high-carbon contract controlled by the landlord. Gas energy consumption (kWh) has reduced by 33% this year, contributing to a 36% reduction in overall scope 1 emissions.
