Carbon accounting software specially built for UK businesses bidding on public sector contracts and reporting under the UK Sustainability Reporting Standards. Measure your Scope 1, 2 and 3 emissions, produce a compliant Carbon Reduction Plan, and get verified, easily.
Three pieces of UK climate reporting have come into force or expanded in the last 24 months. Together, they affect any business that bids for public contracts, sells to the NHS, employs over 250 people, or sits in the supply chain of someone who does.
Any UK government contract above £5 million now requires a Carbon Reduction Plan. PPN 006 (formerly PPN 06/21) sets the format and methodology.
The UK Sustainability Reporting Standards (replacing TCFD) are being phased in for listed companies and larger private businesses. As expectations evolve, Scope 3 emissions is becoming increasingly important. Many organisations are beginning to request this information from their suppliers.
If you employ 250+ people, or turn over £36m+, or have a balance sheet above £18m, you have to report energy use and Scope 1, 2 and some Scope 3 emissions in your annual accounts.These disclosures form part of annual reporting requirements and are reviewed by Companies House and external auditors.
It’s becoming increasingly common for UK businesses to be asked for emissions data as part of tendering and supplier requirements. Larger organisations are placing greater emphasis on Scope 3 reporting, meaning suppliers are increasingly expected to provide reliable emissions information as part of ongoing commercial relationships.
Focus on what matters in practice: the evidence needed for tenders, audits, and supplier approval.
GHG Protocol-aligned, using DEFRA conversion factors. Spend-based and activity-based methodologies for Scope 3, with intelligent estimation where data is incomplete.
Create a carbon reduction plan, compliant with PPN 006, that actually gets you to net zero.
The energy and carbon disclosures you need for your Companies House annual filing, verified by our climate team.
Independent verification of your footprint by our in-house verification team, giving you the assurance you need that your numbers are right.
Send measurement requests to suppliers, monitor responses, and consolidate the data into your footprint. This aligns with the tools increasingly being used across supply chains.
Science-based net zero targets, intervention modelling, and a year-on-year tracking dashboard. Not just a compliance document you file and forget. Beyond a one-off compliance exercise
From self-serve software to fully managed reporting, choose the level of support that matches where your business is.

London's leading full fibre broadband provider has been using Climate Essentials since 2022, moving from active carbon reporting to supplier sustainability clauses, a dedicated Green Team, and measurable emissions reductions.
"Climate Essentials gave us the insight to see where our emissions were actually coming from, and the data to act on it."
A FAQ grounded in what UK businesses are actually asking.
Yes. The Carbon Reduction Plan template we generate as part of our managed services follows the exact structure the Cabinet Office published under PPN 006 (previously known as PPN 06/21). It includes baseline emissions for Scope 1, 2 and the required Scope 3 categories: business travel, employee commuting, upstream transport and distribution, waste, downstream transport and distribution; a stated commitment to net zero by 2050, and the environmental management measures you have in place.
Over a thousand organisations use Climate Essentials, including suppliers who have won government contracts using our outputs.
UK SRS, the UK Sustainability Reporting Standards, is the UK's implementation of the international ISSB standards (IFRS S1 and S2). It is replacing the TCFD framework that UK-listed companies previously reported against.
The biggest practical change: Scope 3 emissions disclosure becomes mandatory, with much greater detail required than under TCFD. If you previously reported under TCFD, UK SRS is the more demanding successor, and it will reach your suppliers too.
Yes, that's exactly who Climate Essentials was built for. The Self-Serve tier starts at just £132/year and is designed for someone in finance or operations (not a sustainability specialist) to complete a full carbon footprint and PPN 006 plan with about two hours of their time.
If you want it done for you, the Managed tier puts a dedicated climate consultant on your account.
We use the UK Government / DEFRA greenhouse gas conversion factors for company reporting, updated annually when the new dataset is published (usually June/July). Spend-based factors are derived from the latest UK Environmentally Extended Input-Output tables.
The Climate Science team at Climate Essentials reviews and implements each annual update — you don't need to. Historical footprints are recalculated using the original year's factors so your year-on-year comparisons remain valid.
Yes. We have an in-house verification service that issues GHG Protocol or ISO 14064-3 aligned verification statements. This matters when a listed customer, auditor or large procurement team asks for third-party assurance on your numbers.
Verification is included in the Managed Service, or as an add-on to Self-Serve.
For most NHS supplier requirements, a PPN 006 Carbon Reduction Plan is the floor, not the ceiling.
NHS England operates the Evergreen Sustainable Supplier Assessment, which expects suppliers to demonstrate ongoing emissions reduction, supply chain engagement, and a credible net zero pathway. Climate Essentials generates the PPN 006 plan you need to bid and the ongoing measurement and reduction tracking the Evergreen assessment expects.
We have a dedicated NHS Suppliers page if your bidding focuses there.
Book a 30-minute demo. We’ll show you how Climate Essentials helps with PPN 006 plan, SECR disclosure, and UK SRS readiness.
