"This forms our benchmark going forwards, allowing us to reduce the footprint of our buildings, and recognise those in our supply chain with our own high sustainability aspirations."

Summary
This project forms an ongoing embodied carbon benchmark for Development Securities, allowing them to target embodied carbon reductions and responsible supply chain members for future developments.
Objectives
- Engage with the supply chain to gain quantities for site
enabling, building envelope and fit-out - Measure material delivery methods and distances
- Measure onsite waste, fuel, electricity and office visitors
- Provide a full embodied carbon footprint from cradle to
grave for the building and onsite contractor activities - Provide geocarbon maps demonstrating carbon
intensities of delivery emissions - Map the supply chain to two levels, including the relative
carbon contribution for each supplier - Recommend reductions of the embodied carbon footprint
for future builds - Provide an embodied carbon benchmark for future builds
Strategy/Delivery
This project engages the supply chain to provide data to Development Securities on the carbon intensity of the building. Suppliers were engaged through onsite meetings and presentations to demonstrate the importance of
embodied carbon.
Full carbon emissions were measured for onsite activities using well-established environmental management systems of the main contractor, Skanska.
The supply chain was fully mapped with regards to carbon, including the impact of varying delivery distances and methods. The costs of offsetting were also compared to the full financial costs for the build – carbon costs were under one percent of the total cost of this development.
Results
Total embodied carbon emissions (cradle to grave) 24,815 tonnes CO2e.
