Our performance

 

As a responsible business it is essential that we look to reduce resource consumption, both through our managed properties and also our development programme.

Measuring and managing resource consumption

Sustainability Data Performance Report 2019

We monitor energy and water consumption at our managed buildings as well as waste produced and its disposal route. By monitoring energy and water usage, we are able to identify opportunities to make savings, reducing operational costs for our occupiers and mitigating our impact on the environment.

We provide consumption information to our occupiers at Environmental Working Groups and occupier meetings. These meetings help identify opportunities to work together to reduce our impact on the environment and inform our occupiers own sustainability policies.

Whilst the carbon emissions and resource consumption from our development sites are not directly attributable to us, we recognise our contribution in producing these emissions and require our contractors to monitor and manage their consumption.

Providing performance data

The figures below provide headline analysis of energy and water consumption, carbon emission and waste collected, using the operational control approach outlined in EPRA guidelines.

For further details on our Basis of Reporting, absolute information and more detailed analysis, please refer to our Sustainability Data Performance Report.

Occupier sub-metered usage from landlord energy supplies is now included in our scope 3 emissions reporting in line with EPRA reporting guidelines. For carbon emissions related to our tenant electricity usage refer to our Greenhouse Gas Emissions Statement in the Annual Report and Accounts.

Carbon emissions factors decreased during the year and for the first time we have been able to report market-based factors emissions, which provides the carbon emissions associated with the electricity supplies purchased by us as landlord. Our gross emissions decreased by 23% due to a significant asset disposals.

There has been a significant increase in carbon emissions at our development sites due to the number of projects on site during the year. There was also a significant increase in Scope 3 emissions attributable to an increase in travel in Europe to verify the origin of development materials.

For Scope 3 emissions in connection with water consumption and waste treatment please refer to the water and waste table.

Our plans for the future

Following our materiality review and climate risk modelling, we have set new longer term energy and carbon targets for our portfolio to:

  • Reduce our energy intensity (kwh/m²) by 40% and our carbon intensity (kgCO2/m²) by 69% by 2030
  • For all new build developments to be net zero carbon from 2030 onward

Additionally, during the forthcoming year, we will be setting out our approach and timescales to become a net zero carbon business.
