Businesses, by law, have to report on their carbon emissions each year. A variety of sources of data is required in order for them to comply. Reporting on bad data is bad for businesses and could result in a hefty fine or worse still, a black mark against the business ruining brand and reputation.

Mandatory Carbon Reporting – Are You Compliant?
Carbon reporting is no longer optional for large UK businesses. The Streamlined Energy and Carbon Reporting (SECR) framework, introduced in April 2019, requires qualifying companies to disclose their energy use and carbon emissions in their annual financial reports. With UK Sustainability Reporting Standards (UK SRS) aligned to the ISSB framework coming into force in 2026, the regulatory landscape is tightening further.
Catalyst Digital Energy provides end-to-end carbon reporting services, from data collection and emissions calculation through to compliance submission and reduction strategy all powered by our EaaSi Carbon platform.
Who Must Report Under SECR?
Your organisation must comply with SECR if it meets two or more of the following criteria:
-
Annual turnover of £36 million or more
-
Balance sheet total of £18 million or more
-
250 or more employees
Qualifying companies are required to report their Scope 1 and Scope 2 greenhouse gas emissions, total global energy use, and an intensity ratioall published within their annual Directors’ Report. Scope 3 reporting is encouraged, and increasingly expected by investors and supply chain partners.
Failure to report accurately carries significant consequences: regulatory fines, reputational damage and, for businesses seeking government contracts, potential exclusion from public sector procurement under Procurement Policy Note PPN 006.
If you are unsure whether your organisation qualifies, our team can assess your obligations at no cost.
Our Carbon Reporting Services
SECR Reporting
We manage the full SECR reporting cycle on your behalf, collecting Scope 1 and Scope 2 emissions data across your estate, calculating greenhouse gas figures in line with DEFRA conversion factors, producing the required intensity ratio, and preparing compliant disclosures for inclusion in your annual report.
Our EaaSi Carbon platform automates data capture and storage, significantly reducing the time and resource burden on your finance and sustainability teams.
Scope 1, 2 and 3 Emissions Reporting
Beyond mandatory SECR obligations, we support full greenhouse gas reporting across all three scopes:
Scope 1 – Direct emissions from your own operations (gas combustion, company vehicles, on-site processes)
Scope 2 – Indirect emissions from purchased electricity and heat
Scope 3 – Value chain emissions including business travel, supply chain, waste and water
Scope 3 reporting is increasingly required by large corporates from their supply chains and by ESG-focused investors. Our automated approach to data capture makes reporting across all three scopes accurate and auditable.
Carbon Reduction Plans
From April 2023, suppliers bidding for UK government contracts above £5 million per annum are required to publish a Carbon Reduction Plan (CRP) a formal commitment to achieving Net Zero by 2050, backed by current emissions data and interim reduction targets.
We prepare Carbon Reduction Plans that fully conform to the requirements of Procurement Policy Note PPN 006, ensuring your business remains eligible for major public sector contracts. Our plans include a current emissions baseline, reduction commitments, progress reporting methodology and Board sign-off documentation.
Carbon Footprint Reduction
Reporting your emissions is only the first step. We work with clients to identify the most material sources of carbon in their operations and develop practical, cost-effective reduction strategies, covering energy efficiency, procurement of renewable electricity, fleet electrification and on-site generation.
Our Cost Stacker™ and EaaSi™ platforms provide the granular consumption data needed to target reductions accurately rather than relying on estimates.
Carbon Offsetting
Where direct emissions reductions are not yet achievable, verified carbon offsetting provides a compliant route to neutrality. We source high-quality, independently verified carbon credits, aligned to internationally recognised standards, and integrate offsetting into your wider net zero strategy as a bridging measure, not a substitute for genuine reduction.
Net Zero Strategy
Meeting 2050 net zero commitments, and the increasing number of interim targets set by regulators, investors and customers, requires a structured, long-term plan. We develop bespoke net zero roadmaps that set science-aligned reduction targets, identify the most cost-effective decarbonisation levers, and establish a reporting framework to track and communicate progress.
The EaaSi Carbon Platform
At the heart of our carbon reporting service is EaaSi Carbon, our proprietary energy and carbon management platform. Rather than relying on manual data collection and spreadsheet-based calculations, EaaSi Carbon automates the gathering of Scope 1, 2 and 3 data from across your estate, applies current DEFRA emissions factors, and produces audit-ready reports at the click of a button.
For multi-site organisations, EaaSi Carbon consolidates data across all locations into a single reporting environment, eliminating the data quality issues that routinely cause compliance errors and restatements.
Carbon Reporting and the 2026 Regulatory Changes
The UK government is introducing UK Sustainability Reporting Standards (UK SRS) from 2026, aligned with the International Sustainability Standards Board (ISSB) IFRS S1 and S2 frameworks. These new standards will require a significant proportion of UK-listed and large private companies to make consistent, investor-focused climate disclosures covering both financial risks from climate change and their own emissions.
For many organisations, this represents a step change in the scale and rigour of carbon reporting required, moving from a relatively simple SECR disclosure to a comprehensive climate-related financial disclosure aligned with TCFD (Task Force on Climate-related Financial Disclosures) principles.
Our team is already working with clients to prepare for UK SRS compliance, assessing current data infrastructure, identifying reporting gaps and building the systems needed to meet the new requirements from day one.
Frequently Asked Questions
Is carbon reporting mandatory for my business?
SECR applies to UK-incorporated companies that qualify as large under the Companies Act, meaning they meet two of three criteria: £36m+ turnover, £18m+ balance sheet, or 250+ employees. Quoted companies on the London Stock Exchange have additional obligations. If you’re unsure whether you qualify, contact our team for a free assessment.
What is the difference between Scope 1, 2 and 3 emissions?
Scope 1 covers direct emissions you produce, gas boilers, owned vehicles, industrial processes. Scope 2 covers indirect emissions from the electricity and heat you purchase, and the SBTi Corporate Net-Zero Standard is moving towards hourly matching of Scope 2 emissions. Scope 3 covers everything else in your value chain, supply chain emissions, business travel, waste, employee commuting and the use of your products. Only Scope 1 and 2 are mandatory under SECR, but Scope 3 is increasingly expected.
What is a Carbon Reduction Plan and do I need one?
A Carbon Reduction Plan is a formal document setting out your organisation’s commitment to achieving net zero by 2050, backed by a current emissions baseline and interim targets. It is mandatory for suppliers bidding for UK government contracts above £5 million per year under PPN 006. Even outside public sector procurement, CRPs are increasingly requested by large private sector customers and ESG-focused investors.
How long does SECR reporting take?
Without dedicated tools, SECR reporting can take internal teams weeks of data gathering and calculation. Using our EaaSi Carbon platform, the process is significantly faster data is collected automatically throughout the year, and reports are generated from verified data rather than estimates. Most clients complete their annual SECR submission in days rather than weeks.
Can you help if we’ve never reported before?
Yes. We work with many organisations completing their first SECR report. We start with a data audit to establish your baseline, identify any gaps in your energy and emissions data, and build the reporting framework you’ll use going forward. Getting the baseline right is critical it’s the reference point against which all future reductions are measured.
What does carbon offsetting involve and is it credible?
Carbon offsetting involves compensating for emissions you cannot yet eliminate by funding verified projects that remove or prevent an equivalent amount of CO₂ elsewhere such as reforestation, renewable energy development or methane capture. Credibility depends entirely on the quality of the credits. We only source offsets verified under internationally recognised standards, and we are transparent about the role of offsetting as a bridging measure rather than a substitute for genuine reduction.
