SECR statement for accounting period May 2024 – April 2025 Reporting and performance
Emissions statement continued In January 2025, our Scope 1 and 2 emissions for our financial year 2023/24 obtained limited assurance from Achilles as part of their Carbon Reduce certification. This identified some minor errors in our data. The audited data for 2023/24 is shown in this report. These errors relate to a change of -1,007.35t CO 2 e or -4%. Over the last financial year, we have made three acquisitions – RJ McLeod (June 2024), Purestream (September 2024) and McCormack Drilling (October 2024). This has led to an overall increase of 69% in our Scope 1 and 2 emissions. As this is greater than 5% we will recalculate our baseline next financial year once we have a full twelve months of data for these acquisitions. Overall, our Scope 1 and 2 emissions have gone up by 63% in absolute terms and 13% in intensity (tCO 2 e/£m revenue). This is primarily due to business growth through acquisition over this financial year. When we recalculate our baseline next year to incorporate our acquisitions we will be able to do a more like-for-like comparison. Scope 3 emissions For the first year we can report our Scope 3 emissions in line with the Greenhouse Gas Protocol for categories 1 to 7. All other Scope 3 categories are seen as not applicable or de minimis. The applicability of the categories will be reviewed annually and data reported on any additional categories as identified going forward.
Assurance This data has received limited assurance by Achillies, having met the requirements of Carbon Reduce certification, confirming we have measured our greenhouse gas emissions in accordance with ISO 14064 Part 1 2018 and are committed to managing and reducing our emissions in respect of our operational activities. Energy efficiency activities During the 2024/25 assessment period, OCU Group undertook several initiatives to enhance our energy efficiency, including: • Continuing to transition to hybrid and electric vehicles. • Procuring 18 gas-free e-hotboxes. • Installing further EV charging points at key locations in our site network. • Completing the rollout of Samsara telematics. • Investing in George, our new and more efficient pipe pusher. • Trialling new technology such as electric mini‑excavators. Further information on this can be found on page 63. Future changes to our reporting As part of our commitment to continuous improvement, we will adjust our base year emissions inventory to account for significant changes that result in an increase or decrease in emissions of greater than 5%. Additionally, we may choose to recalculate our baseline for changes less than 5%, particularly when structural changes occur.
Structural changes , such as acquisitions, divestitures, or mergers of businesses or facilities, will be factored into our emissions inventory adjustments. This makes sure that our data remains accurate and consistent. Methodology changes include updates to emission factors, enhanced data access, and revised calculation methods or protocols. We follow Defra guidance to recalculate previous years’ emissions whenever new emission factors are released, ensuring our reporting stays current and reflects the best available data. Discovery of significant errors: If we identify a significant error or a series of cumulative errors, we will recalculate our emissions to correct these discrepancies. Change in organisational boundary: Any changes in our organisational boundary will prompt a recalculation of our emissions to make sure our reporting encompasses all relevant operations. Change in operational boundary: Similarly, changes in our operational boundary will be reflected in our emissions inventory to maintain accuracy and comprehensiveness. OCU Group is committed to continuous improvement in our environmental reporting and management practices. We will continue to refine our data collection methods and reporting accuracy to better understand and mitigate our environmental impact.
