Summary of the contracting process

The Department for Energy Security and Net Zero seeks to digitally upgrade the UK’s National Atmospheric Emissions Inventory System. The contract, focusing on information technology services, involves a comprehensive rebuild to ensure the system's robustness and up-to-date functionality. The procurement, at the award stage as of 3rd April 2025, commenced on 23rd October 2023 and is set to conclude by 30th September 2026. Key contractors, including KPMG LLP, Mott MacDonald, and Aether Limited, will simplify the current system, build a modular new system, and ensure transparent emissions calculation processes. This project covers the entire UK region and is aligned with the statutory requirements for reporting greenhouse gas and pollutant emissions.

This tender offers substantial opportunities for technological companies specialising in system architecture, data analysis, and software development. Businesses with expertise in modular software systems, environmental data processing, and compliance with international emission reporting standards are well-suited to compete. The successful enhancement of the NAEI system will provide critical support to the UK Government’s climate commitments, offering long-term collaboration potential for businesses capable of ensuring high standards in technology and environmental science.

Notice Title

Digital Upgrade of the UK's National Atmospheric Emissions Inventory System Contract Modification

Notice Description

DESNZ are procuring services to substantially upgrade & improve the software system used to generate annual estimates of Greenhouse Gas & pollutant emissions across the UK. Currently a set of XLS files, Access databases & SQL, with other software linking these, are used to store, process & report data. Outputs from this system are used by UK Gov to report against our emissions targets (inc. Carbon Budgets, Paris Agreement). Based on a requirement that will be provided you will develop a new software approach which streamlines the system, using standard architecture across all inventory sectors to store, analyze, and report emissions.

Lot Information

Digital Upgrade of the UK's National Atmospheric Emissions Inventory System

The National Atmospheric Emissions Inventory (NAEI) quantifies national emissions of a range of greenhouse gases (GHGs) and air pollutants to the atmosphere from a variety of sources. The NAEI, which includes over forty different pollutants, is updated and published annually, and charts the history of the UK's atmospheric emissions since 1970. The current digital architecture of the NAEI system has evolved across the last 20+ years in a stepwise manner according to the growth of the system and the increasing scientific and technical complexity of the emissions calculations. The system is made up of a mix of technologies (covering Excel, Access, MySQL, R and Python scripts) and is now in need of a wholesale rebuild to make the system more robust, consistent and up to date. This contract delivers the following: * Simplify the technology suite used in current system * Build the new system in a modular way * Ensure the end-to-end process for calculation of emissions is transparent and traceable
