AHMM Publishes annual carbon emissions report 02.10.24

AHMM has published its annual carbon emissions report, as part of its commitment to the Science Based Targets initiative (SBTi).

The AHMM Carbon Emissions Annual Report 2023 includes an overview of the company’s Scope 1, 2, and 3 operational emissions for 2023, as well as the upfront carbon emissions of its architectural projects that achieved practical completion in 2023. These figures are reported in comparison to the previous year, as the baseline for the practice’s reduction pathway and carbon disclosure is the calendar year 2022. In recognition of the difference in scale of carbon emissions between projects and company operations, the report reviews the two measurements and their contributing factors separately.

The report shows that from 2022 to 2023 the company’s total operational emissions have reduced from 1406 tCO2e to 1006 tCO2e, with the 2023 figure being 323 tCO2e below target based on AHMM’s net zero trajectory plan. The biggest savings in operational carbon have been made in Scope 3, with a total reduction of 513 tCO2e; this has been attributed to changes made in IT equipment purchasing and the studio’s events programme. Scope 1 and 2 emissions, which derive from the gas boilers at AHMM’s London headquarters and purchased electricity across all location, have increased in 2023, which is a result of more staff returning to the office following the pandemic.

Although not a requirement of the SBTi, the report also includes the upfront carbon emissions of AHMM’s projects that achieved practical completion in the reporting periods, with a reduction trajectory target based on the upfront carbon intensity of AHMM’s 2022 buildings and working to LETI 2030 targets. This sets a target for 593 kgCO2e/m2 GIA for 2023. The report shows that the total upfront carbon emissions of AHMM’s projects that achieved practical completion increased from 80351 tCO2e to 102893 tCO2e from 2022 to 2023, but the carbon intensity of the projects reduced from 628 kgCO2e/m2 GIA to 553 kgCO2e/m2 GIA. This is due to AHMM delivering an increased proportion of retrofit projects, and buildings with larger footprints but greater carbon efficiency.
