Decarbonising our portfolio

We're committed to playing our part in tackling the climate crisis. 

Throughout the past decade, we’ve established ourselves as a global sustainability leader in our sector. We’ve set and achieved ambitious science-based carbon targets, reduced energy use in our buildings, and invested in renewable energy on our transition to net zero.

Key milestones

Transitioning to net zero carbon

To support the world in limiting global warming to 1.5ºC we are committed to transitioning to net zero by 2040, whilst building resilience to climate change. Our ambitious science-based carbon reduction target (SBT) will see us reduce our scope 1, 2 and 3 emissions by 47% by 2030 and by 90% by 2040 from a 2019/20 baseline.

Starting with The Forge, the UK’s first commercial development to have been designed in line with the UK Green Building Council’s definition of a net zero building, all our future developments will be net zero.

 

Our net zero transition investment plan 

Our £135m Net Zero Transition Investment Plan (NZTIP), launched in 2021, is key to achieving our SBT and we are making strong progress. To date, we have invested £32m, including transforming our office buildings by replacing existing heating and cooling systems with air source heat pumps (ASHPs) and installing Solar PV across our retail sites. Our portfolio is 100% compliant with the 2023 MEES EPC E or above requirements. In addition, 56% of our portfolio – 51% of offices and 61% of retail - is already EPC B or above.

Following the publication of the Transition Plan Taskforce (TPT) Disclosure Framework in October 2023, we have been developing our Climate Transition Plan, mapping out the actions we need to take to decarbonise our business and reach net zero across our value chain by 2040.
 

Here’s how we’re doing it:

Tackling our full carbon footprint

We recognise that we also have an important role to play in influencing emission reduction of our supply chain and customers.

Every year we report on the entire range of measurable carbon emissions associated with our business, including the energy we use heat and power our managed properties, as well as indirect emissions such as embodied carbon produced by our suppliers.

Here are some of the ways we're tackling our full carbon footprint:

Designing and developing our new schemes sustainably

Nearly 50% of whole life carbon emissions of a building occur before it even completes and this proportion is growing as the UK grid decarbonises. We therefore continue to design and construct our buildings to be net zero and in 2023 set an ambitious target to Reduce average embodied carbon by 50% compared with a typical building by 2030.

In 2023, we delivered The Forge in Southwark, the first UK net zero commercial building constructed and operated in line with the UK Green Building Council's (UKGBC) framework definition for net zero buildings. We continue to design and build net zero buildings.

We have made considerable progress in reducing upfront embodied carbon across our development pipeline, achieving a 40% reduction compared to a typical building. We monitor embodied carbon from the outset of each scheme, and collaborate with our supply partners to reduce emissions through:

• Structural retention and material reuse 
• Designing-out material 
• Changing our specifications to low-carbon materials alternatives

Our Materials Brief, launched in 2024, is proving instrumental in shaping our developments, driving embodied and whole-life carbon reduction. It guides our design team to identify key opportunities for material reuse, alternative materials and innovative solutions in collaboration with our supply partners. The brief also helps align our developments to green building certification requirements, promotes use of local suppliers, and upholds ethical sourcing and human rights standards. This holistic approach is supporting our commitment
to creating sustainable places

We continue developing our net zero carbon strategy for our mixed-use urban neighbourhoods, aiming to apply the same level of diligence on our residential-led projects as we do for our offices. We looked at the life-cycle impact of our masterplans and set targets for embodied and operational carbon based on in-depth modelling and financial appraisal. We are confident that this sets us on a path to providing climate-resilient homes that will stand the test of time. 

Credible carbon offsetting

We recognise that despite our plans to transition to net zero, we’ll need to offset some unavoidable remaining emissions from our development activity. We’re focused on ensuring each credit is independently verified, transparent and traceable meeting UKGBC and SBTi principles. As such, we’ve joined The Lowering of Emissions by Accelerating Forest Finance (LEAF), a public-private coalition, supported by governments (UK, US and Norway), that seeks to mobilise finance to protect tropical forests at huge scale. LEAF carbon offsets are verified by Architecture for REDD+ Transactions (ART).

Resilience

To ensure we have resilient assets that meet the changing needs of our people and customers, we invest in low-carbon, energy efficient buildings and we’re moving from dependence on gas towards all-electric solutions like air source heat pumps.

Part of becoming more resilient is being aware of the physical risks of climate change, like flooding, sea level rise and overheating. As the climate becomes hotter and wetter, we need to be sure our assets still deliver the same quality of experience to our customers. 

We assess physical risks based on the location of assets and their exposure to individual hazards resulting from climate change. In 2024/25 we partnered with Munich Re to improve the assessment of portfolio exposure to these risks. The assessment of current risk exposure utilises Munich Re’s proprietary models and loss data, which weight hazards based on their damage potential, normalising the average annual loss rates for property damage within each hazard zone for the respective perils (earthquake, storm/tropical cyclones/tornadoes, flood/storm surge).

As one of the founding signatories of the Better Buildings Partnership (BBP) Climate Commitment, we align with the BBP’s definition of climate resilience. As such, we have a strategy in place to:

  • mitigate the worst impacts of climate change by becoming net zero carbon by 2040, in line with our science-based target
  • adapt to operating in a world in which climate-driven disruption is more frequent and severe, ensuring assets exposed to climate risks have adaptation measures in place
  • disclose climate-related information to investors, regulators and other stakeholders in a useful and timely way, reporting in line with TCFD since 2017

TCFD

The Task Force for Climate-related Financial Disclosures (TCFD), launched in 2017, encourages businesses to build resilience to the possible outcomes of climate change. In line with the Task Force on Climate-related Financial Disclosures’ (TCFD) recommendations, since 2017 we’ve committed to assessing and reporting on material climate change risks across our portfolio, ensuring we have the appropriate strategy and mitigation plan in place. Our full TCFD disclosure can be found in our Annual Report.
