We are committed to sustainability by the re-use and careful management of existing buildings. We improve and extend the economic life of our buildings.
Energy and greenhouse gas emissions
We report our greenhouse gas emissions in accordance with UK legislation. The figures relate to landlord controlled common parts such as staircases. The numbers are therefore minimal.
Overall, energy consumption has increased by a small amount. Due to the increased use of renewable energy in the national grid, greenhouse gas emissions in the portfolio decreased by 18% from 1,565.5 tonnes to 1,288 tonnes. We continue to prioritise installation of low emission lighting in operational controlled areas and our ongoing programme of refurbishment includes upgrading of boilers and improvements in the inherent efficient operation of the buildings.
Greenhouse gas emissions for the portfolio, head office and refurbishment sites (tCO2e) are set out below. Overall, energy consumption is, in absolute terms, small, covering mainly landlord-controlled areas. The decrease in Scope 1 emissions is attributed to replacing a faulty boiler in Carnaby and improvements as a result of refurbishment of Thomas Neals in Seven Dials.

The chosen emissions intensity is common parts floor areas, which has been measured in 67 of the 125 reported properties with common parts only and the emissions intensity figure has been obtained of 49.5 kgCO2e/m2 (0.05 tonnes CO2e/m2), an increase over last year’s 37.3 kgCO2e/m2 (0.04 tonnes CO2e/m2).

We exceeded our target recycling/composting rate with 57% recycled and composted at Carnaby and Seven Dials. We encourage composting by our restaurant tenants, and active engagement with tenants has increased the proportion to over 10%. The remaining waste is diverted from landfill to energy from waste.
We achieved a 33% recycling rate at Chinatown having introduced segregated waste management facilities at our service yard. Our refurbishment projects diverted, on average, over 98% of waste from landfill.
Use of materials
We maximise the re-use of materials on site in all our refurbishment projects, with a signifi cant proportion of the primary structure and external façade retained. Similarly, our approach is to re-use timber where possible. Timber features such as windows, joists, fl oorboards, staircases and paneling were retained where possible. For the small volume of timber purchased, 92% was Forest Stewardship Council (FSC) certifi ed and overall 96% was sustainably sourced with full chain of custody.
We recognise the importance of promoting biodiversity. The West End is an intensively used urban area, which needs thriving and connected green spaces. This is important for both wildlife and the health and wellbeing of occupiers and visitors. We have continued our membership of Wild West End. West End property owners are working together to encourage wildlife, and create greater connections with nature for residents, visitors and workers to enjoy. This year we made further progress with our goal to improve the biodiversity of empty and inaccessible roof tops, by installing an additional 1,334 sq. ft of sedum pods in Carnaby and 60 additional window boxes were installed throughout the portfolio. This equates to a 16% increase in total area covered from 8,127 sq. ft to 9,461 sq. ft.
WILD WEST END WON BIG BIODIVERSITY CHALLENGE AWARD 2017
The work we are doing for pollinators was acknowledged with a visit by Lord Gardiner of the Department for Environment, Food and Rural Affairs during Bees’ Needs week. We will continue in the year ahead to promote biodiversity initiatives and select similar roofs throughout the portfolio to install larger areas of sedum pods where space allows.
