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 2018

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 tenant 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.

Tenant submetered usage from landlord energy supplies is included in our emissions reporting in line with EPRA reporting guidelines.

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 18% due to a reduction in gas consumption.

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 to investor meetings in the United States during the year.

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

For the year ending 31 March 2018 we plan to reduce our energy consumption by 2.5% on a like-for-like basis with a view to achieving similar reductions year-on-year until 2020.

We also plan to achieve an annual carbon intensity reduction of 6.3% and reduce our carbon emissions intensity by 40% by 31 March 2022.
