06.05.20  LETI 2020 Workstreams

27.01.20  Climate Emergency Design Guide

We've launched our Climate Emergency Design Guide, which sets out the approach, targets and benchmarks that developments in the UK need to achieve to reach Net Zero in operation. This means that the developers, consultants and policy officers in the UK will have a reference point to define what their developments should achieve to ensure our climate change targets are met.

This is required, as LETI believes that by 2030 100% of all new buildings will need to operate at Net Zero, which means that by 2025 100% of all buildings must be designed to Net Zero. This will give 5 years to sense check, refine and validate this approach.​

Supplementary guidance to the guide is provided in our Embodied Carbon Primer.
