Summary of the contracting process

The Department for Energy Security & Net Zero is commissioning research services for the second UK Greenhouse Gas Inventory Improvement Programme. This procurement covers greenhouse gas emissions reporting for the energy, waste, and industrial processes and product use sectors. The appointed supplier or consortium will lead the programme, develop methodologies, undertake sector-specific original research, engage stakeholders, and generate new or updated emission factors and activity data. The work is intended to improve the scientific robustness, transparency and resilience of the UK greenhouse gas inventory, including its treatment of diffuse emissions and uncertainty. Delivery will take place across the United Kingdom. The requirement includes desk research, modelling, laboratory testing, fieldwork, methodology development and quality assurance. It is a services opportunity classified as research services.

The buyer has reached the tender stage and invited offers through an open procedure. Questions must be submitted by 14 August 2026 at 17:00, and tenders must be submitted by 27 September 2026 at 16:00.

The contract is planned to run from 30 November 2026 to 31 March 2030, with the award decision due by 27 October 2026. There is one lot. Evaluation is based on technical quality at 80%, social value at 10%, and value for money at 10%; price is assessed separately through the pricing schedule. Electronic submission is allowed in English.

This opportunity suits a multidisciplinary organisation able to lead a consortium and manage a complex, research-led programme. Relevant capability includes climate science, mathematical emissions modelling, greenhouse gas inventory methodology, Intergovernmental Panel on Climate Change guidelines, United Nations Framework Convention on Climate Change accreditation, and international emissions reporting standards. Experience across energy, waste and industrial processes and product use is central, while knowledge of agriculture is also essential. Suppliers should be able to combine qualitative and quantitative research, desk analysis, stakeholder engagement, laboratory testing, fieldwork, model development and rigorous quality assurance and quality control. A dedicated programme management office is required. Strong bidders will also demonstrate academic, research institution, SME and diverse-supply-chain participation, measurable social value outcomes, proportionate resourcing, cost control and risk reduction.

Notice Information

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.
