Carbon Reduction Plan
Commitment to achieving Net Zero
TSO is part of Williams Group Limited. Williams Lea is committed to achieving Net Zero emissions by 2050.
Baseline Emissions Footprint
Baseline emissions are a record of the greenhouse gases that have been produced in the past and were produced prior to the introduction of any strategies to reduce emissions. Baseline emissions are the reference point against which emissions reduction can be measured.
Baseline year: 2023
Williams Lea completed its first global greenhouse gas accounting process for scope 1, 2 & 3 emissions using 2022 data but refined this in 2023 due to structural changes and a closer reflection of normal operations after the Covid-19 pandemic.
Baseline year emissions:
Scope 1: Total (tCO2e) 177
Scope 2: Total (tCO2e) 2,085
Scope 3: Total (tCO2e) 30,648
Total emissions: 32,831
Current Emissions Reporting - Reporting year: 2024
Scope 1: Total (tCO2e) 225
Scope 2: Total (tCO2e) 2,598
Scope 3: Total (tCO2e) 28,165
Total emissions: 30,987
Emissions Reduction Targets
The targets set by Williams Lea to reduce its GHG emissions in line with the latest climate science are:
Overall Net-Zero Target:
Williams Lea commits to reach net-zero greenhouse gas emissions across the value chain by 2050
Near-Term Targets:
Williams Lea commits to reduce absolute scope 1 and 2 GHG emissions 58.8% by 2034 from a 2023 base year
Williams Lea also commits to increase active annual sourcing of renewable electricity from 11.3% in 2023 to 100% by 2030
Williams Lea further commits to reduce scope 3 GHG emissions 63.8% per EUR value added by 2034 from a 2023 base year
Long-Term Targets:
Williams Lea commits to reduce absolute scope 1 and 2 GHG emissions 90% by 2050 from a 2023 base year. Williams Lea also commits to reduce absolute scope 3 GHG emissions 90% within the same timeframe.
Carbon Reduction Projects
Completed carbon reduction initiatives:
The following environmental management measures and projects have been completed or implemented since the 2023 baseline. The carbon emission reduction achieved by these schemes equate to 51 tCO2e, a 0.15%ge reduction against the 2023 baseline and the measures will be in effect when performing the contract.
Consolidation of office space in Norwich average annual reduction of 2.5tCO2e of natural gas use.
Consolidation of office space in Norwich average annual reduction of 41tCO2e of electricity use.
Consolidation of office space in Bristol average annual reduction of 2.2tCO2e of natural gas use.
Consolidation of office space in Bristol average annual reduction of 4.2tCO2e of electricity use.
Consolidation of office space in Alloa average annual reduction of 1.1tCO2e of electricity use.
Installation of LED lighting at the DPC London facility average annual reduction of 1.3 tCO2e of electricity.
Continued accredited certification to ISO 14001:2015 for our Environmental Management System.
Completion of the Energy Savings Opportunity Scheme (ESOS) phase 3 audits.
Verification of our global Scope 1, 2 & 3 Greenhouse Gas emissions data to reasonable assurance level in accordance with the ISO 14064-1:2019 standard.
Validation of our GHG reduction targets by the Science Based Targets initiative (SBTi).
In the future we hope to implement further measures such as:
Purchase 100% renewable energy for all Williams Lea locations globally.
Increase supplier engagement to enhance data quality.
Reduce our scope 1 fuel use in the US to electric vehicles.
Replace lighting with high efficiency LED technology.
Declaration
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 (or equivalent management body).
