Summary of the contracting process

The Department for Energy Security & Net Zero is procuring research services for the second UK Greenhouse Gas Inventory Improvement Programme. This requirement covers greenhouse gas emissions reporting for the energy, waste, and industrial processes and product use sectors, excluding agriculture, although knowledge of agriculture is essential. The appointed supplier or consortium will lead the programme, develop methodologies, carry out sector-specific original research, engage stakeholders, and generate new or updated emission factors and activity data. Work will use desk-based analysis, modelling, laboratory testing, fieldwork and collaborative research, supported by rigorous quality assurance. The intended result is a more scientifically robust, transparent and resilient UK greenhouse gas inventory, with improved treatment of diffuse sources and emissions uncertainty. Delivery is across the United Kingdom.

The procurement has reached tender: the buyer invited offers through an open procedure, with electronic submission allowed in English. It is one lot, with an estimated value of £3,010,000 excluding VAT, or £3,612,000 including VAT. The contract period is 30 November 2026 to 31 March 2030. The deadline for clarification enquiries is 14 August 2026 at 17:00, and the tender submission deadline is 27 September 2026 at 16:00. The anticipated award decision date is 27 October 2026. Evaluation is weighted 80% technical delivery, 10% social value and 10% value for money; price is assessed separately through the pricing schedule. The lot is identified as suitable for SMEs and VCSEs.

This opportunity suits a lead organisation able to assemble and manage a multidisciplinary research consortium. Relevant capability includes climate science, greenhouse gas inventory development, mathematical emissions modelling, Intergovernmental Panel on Climate Change guidelines, United Nations Framework Convention on Climate Change accreditation, and international emissions reporting standards applied to sectoral processes. Suppliers need experience developing methodologies, emission factors and activity data, alongside qualitative and quantitative research, stakeholder engagement, laboratory testing, fieldwork and model development. A dedicated programme management office is required to coordinate delivery, and strong quality assurance and quality control arrangements are expected. Proposals should demonstrate effective involvement of SMEs, academic and research institutions and diverse suppliers, with measurable social value outcomes, proportionate resourcing, cost control, risk reduction and clear reporting arrangements.

Notice Title

Greenhouse Gas Inventory Improvement Programme - 2 Energy, Waste, and Industrial Processes and Product Use

Notice Description

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.
