Preoptima

Preoptima is a science-driven software provider dedicated to advancing whole life carbon (WLC) compliance in the built environment. Our innovative digital tools bridge the gap between design, planning, and carbon policy implementation, empowering stakeholders across both the private and public sectors.

Our PACER (Planning Application Carbon Evaluation and Reduction) product directly supports digital planning by automating the review of whole life carbon assessments (WLCAs) submitted as part of planning applications. Developed in collaboration with Westminster City Council and funded by Innovate UK, PACER enables Local Planning Authorities (LPAs) to streamline compliance checks, evaluate projects against benchmark data, and enforce WLC policies more efficiently. The platform reduces reliance on specialised personnel by upskilling case officers and acting as a ‘technical co-pilot,’ ensuring consistency and accuracy in planning processes.

By addressing critical resource and expertise gaps, PACER enables LPAs to meet evolving regulatory demands and national carbon targets, helping embed sustainable decision-making into planning workflows. Additionally, PACER generates valuable data for future policy development, making it a vital tool for delivering Net Zero-aligned urban development.

Over 40 LPAs and public sector organisations have been involved in the development of PACER, ensuring it is a scalable solution that can be customised to LPAs at any stage of their sustainability journey.

Preoptima’s mission is to simplify carbon compliance, ensuring it becomes an integral part of the planning system and enabling authorities to lead the way in sustainable development.
