This public procurement process falls under the services category with a CPV code of 73110000 for research services, using an open procedure. Interested parties should participate before the enquiry deadline on 14th August 2026, with submissions due by 27th September 2026. The project, centralised in the UK, aims to enhance the UK's GHG inventory alignment with international standards, with the entire programme active from 30th November 2026 to 31st March 2030. This tender presents a substantial opportunity for businesses specialising in environmental research, emissions modelling, and international emissions reporting standards to engage in a high-impact national programme. Ideal participants would be multidisciplinary teams with expertise in climate science, IPCC guidelines, and emissions modelling. The contract's requirement for a dedicated programme management office implies suitability for businesses with robust project management skills and experience in coordinating large-scale research initiatives. This enhances opportunities for SMEs and VCSEs to partner with academic institutions and diverse supply chains, leveraging collaboration for innovative research contributions and strengthening their market presence. The estimated value of the contract is approximately £3,612,000, providing significant growth prospects for qualifying suppliers. ## Notice DESNZ is seeking to procure a supplier(s) to deliver and lead the second UK Greenhouse Gas (GHG) Inventory Improvement Programme of research (IIP-2). The research programme will involve an organisation with expert technical understanding of inventory issues as they relate to issues across the UK economy leading a consortium to develop methodologies, deliver sector-specific original research and engage relevant stakeholder, generating new or updated emission factors and activity data. This will continue to ensure that the UK GHG inventory is in alignment with Intergovernmental Panel on Climate Change guidelines and reflects government decarbonisation efforts. This programme is being published as two procurements. This one is the Energy, Waste, and Industrial Processes and Product Use (IPPU) emissions reporting sectors. Refer to Page 55 of the ITT Document Both programmes will require a multidisciplinary teams with expertise spanning but not limited to climate science, mathematical emissions modelling, IPCC guidelines, UNFCCC accredited experts and international emissions reporting standards, specifically as applied to sectoral processes (excluding the agriculture sector but a knowledge of the agriculture sector is essential). In addition, a dedicated programme management office will be essential to coordinate and oversee delivery. To ensure comprehensive and high-quality outcomes, the programme will employ a blend of qualitative, quantitative, modelling, and collaborative research approaches. These will include desk-based analysis, stakeholder engagement, laboratory testing, model and methodology development, fieldwork, and rigorous QA/QC procedures. The intended outcome is a scientifically robust and transparently enhanced UK GHG inventory. The inventory will be more resilient to future changes and capable of quantifying emissions uncertainty in a reproducible and interpretable manner. It will also improve the representation of emissions from diffuse sources, using open and transparent models and methods that allow for the identification and correction of risks and weaknesses. ## Key Details | Field | Value | | --- | --- | | Publication source | Find A Tender Service | | Latest notice | https://www.find-tender.service.gov.uk/Notice/073067-2026 | | Notice type | UK4 - Tender Notice | | Procurement type | Standard | | Procurement category | Services | | Procurement method | Open | | Procurement method details | Open procedure | | Tender suitability | SME, VCSE | | Awardee scale | Not specified | | All stages | Tender | ## Dates | Field | Value | | --- | --- | | Publication date | 3 Aug 2026 | | Submission deadline | 27 Sep 2026 | | Future notice date | Not specified | | Award date | Not specified | | Contract period | 30 Nov 2026 - 31 Mar 2030 | | Recurrence | Not specified | ## Values | Field | Value | | --- | --- | | Tender value | £3,010,000 | | Lots value | £3,010,000 | | Awards value | Not specified | | Contracts value | Not specified | ## Status | Field | Value | | --- | --- | | Tender status | Active | | Lots status | Active | | Awards status | Not specified | | Contracts status | Not specified | ## Buyer | Field | Value | | --- | --- | | Main buyer | DEPARTMENT FOR ENERGY SECURITY & NET ZERO | | Locality | LONDON | | Post town | South West London | | Postcode | SW1A 2HP | | Country | England | | ITL 1 | TLI London | | ITL 2 | TLI3 Inner London - West | | ITL 3 | TLI35 Westminster and City of London | | Local authority | Westminster | | Electoral ward | St James's | | Westminster constituency | Cities of London and Westminster | | Delivery location | Not specified | ## CPV Codes ### Divisions - 73 - Research and development services and related consultancy services ### Codes - 73110000 - Research services ## Release History - 3 Aug 2026 at 10:05 - Tender - UK4 - Tender Notice - https://www.find-tender.service.gov.uk/Notice/073067-2026 ## Documents - https://www.find-tender.service.gov.uk/Notice/073067-2026 3rd August 2026 - Tender notice on Find a Tender ## Notice URLs - https://beisgroup.ukp.app.jaggaer.com/esop/guest/go/public/opportunity/current - https://www.legislation.gov.uk/ukpga/2023/54/contents ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
