Publication Date: October 2025

Commitment to achieving Net Zero Recognising that climate change poses a threat to the economy, nature and society-at-large, AWW commits to take action in order to (as a minimum): 1. Halve our greenhouse gas emissions before 2025; 2. Achieve net zero emissions before 2030; 3. Disclose our progress on a yearly basis. In doing so, we are proud to be recognised by the United Nations Race to Zero campaign, and join governments, businesses, cities, regions, and universities around the world with the same mission.

Baseline Emissions Footprint

Emissions Reduction Targets

Baseline Year: 2020/21 (05.04.2020 - 04.04.2021)

Target 1: Halve our greenhouse gas (GHG) emissions before 2025

Additional Details relating to the Baseline Emissions calculations: AWW Baseline is measured from the company’s first carbon accounting period of 5.4.2020 to 4.4.2021.

AWWreduced Carbon Account: Act Since the 20/21 baseline, reported GHG emissions have been from 65.151 tCO2e to 34.764 tCO2e 80 70

This is a reduction of approximately 46.64% 60

The usable data available at the time was limited to AWW business energy use, and business car travel. Since the 20/21 report was published, the data pool has been increased as a consequence of the AWW Carbon Action Plan, and includes additional Scope 3 Items.

Acknowledging the later datasets being more extensive, the decision was made to continue to use the 20/21 reporting period as the baseline total tCO2e figure from which to assess future progression.

Carbon Reduction Projects Completed Carbon Reduction Initiatives The following environmental management measures and projects have been completed or implemented since the 2020/21 baseline.

The carbon emission reduction achieved by these schemes equate to 30.39 tCO2e, a 46.64% reduction against the 2020/21 baseline and the measures will be in effect when performing the contract.

Since AWW’s first Carbon Action Plan in 2021, the following carbon reduction projects have been planned/progressed/completed (as indicated below): Scope & Description Scope 1 Vehicle fleet

Scope 2 Office premises electricity use Scope 2 Office premises electricity use Scope 2 Office premises electricity use Scope 2 Office premises electricity use Scope 3 Reporting General

Action Reduce by 1/3 and replace diesel/petrol with electric/hybrid / reduce personal car usage (personal car usage increase is the reason for the Scope 1 increase in 24-25) Reduce through floorplate planning efficiencies Reduce through better data collections and efficiency improvements to server and equipment Changing supplier/lease to reduce carbon factor Introduce electricity monitor to each office to help control and limit use Increase accounting of Scope 3 emissions year-on-year Increase frequency to quarterly internal reporting to evaluate data and action more regularly

Declaration and Sign Off This Carbon Reduction Plan has been completed in accordance with PPN 06/21 and associated guidance and reporting standard for Carbon Reduction Plans.

Emissions have been reported and recorded in accordance with the published reporting standard for Carbon Reduction Plans and the GHG Reporting Protocol corporate standard and uses the appropriate Government emission conversion factors for greenhouse gas company reporting.

Scope 1 and Scope 2 emissions have been reported in accordance with SECR requirements, and the required subset of Scope 3 emissions have been reported in accordance with the published reporting standard for Carbon Reduction Plans and the Corporate Value Chain (Scope 3) Standard.

This Carbon Reduction Plan has been reviewed and signed off by the Board of Directors.
