Electricity consumption is our second largest source of greenhouse gas emissions. As the cost of electricity rises, making our buildings and operations more energy efficient is a priority. Our indirect emissions (which are primarily derived from using electricity) in 2017 were 608,516 tonnes of CO2e, a 1.5% decrease from 2016. This decrease primarily reflects improvements in energy efficiency at Swire Properties’ portfolio in Mainland China.
Our operating companies exchange information about energy efficiency (from this year through the Carbon Working Group under SwireTHRIVE). The Swire Properties sustainable building design policy requires new and substantially renovated buildings to try to obtain the highest or, as a minimum, the second highest international or local building environmental certification. At the end of 2017, 54 buildings, representing 64% of Swire Properties’ portfolio, had been certified or provisionally certified as green buildings under BEAM, BEAM Plus and LEED independent rating systems. Some other buildings were renewing their BEAM Plus Existing Buildings ratings.
Operating companies are encouraged to reduce energy use and to set energy efficiency targets. Since 2008, Swire Properties has reduced its annual energy consumption in its Hong Kong portfolio by 53 million kWh, which is in line with its 2020 target. In its Mainland China portfolio, it has reduced its annual energy consumption by 17 million kWh from the consumption which would have occurred if no changes had been made, putting it on track to meet its 2020 target.
As part of its SD2030 strategy, Swire Properties is committed to the following by 2020:
2017 progress update
Reduced the carbon intensity of its Hong Kong portfolio by 23%
A 27% reduction in carbon intensity in its Hong Kong portfolio
Reduced the energy intensity of its Hong Kong portfolio by 29.5%
A 29% reduction in energy intensity in its Hong Kong portfolio
Reduced the energy consumption of its Mainland China portfolio by 17 million kWh/year
A reduction in energy consumption in its Mainland China portfolio of 23 million kWh/year
Swire Properties offers free energy audits to tenants. Since 2008, audits have covered 468,000 m2 of commercial space, identifying potential annual energy savings of 7.9 million kWh.
Swire Properties has obtained ISO 50001:2011 certifications for its energy management systems in all its Hong Kong portfolio and at its Taikoo Li Sanlitun, Beijing and TaiKoo Hui, Guangzhou developments in Mainland China.
The principal companies in the HAECO Group carry out energy audits every five years, with the view to save energy and manage its impact on the environment. HAECO’s hangars need a lot of light so that defects in aircraft can be seen and repairs can be made. Lighting accounts for 40% of HAECO’s electricity consumption. More natural light means less energy used to produce artificial light. HAECO Xiamen has installed light sensors to control the amount of artificial light. This reduces electricity consumption by around 160,000kWh a year.
Swire Waste Management is replacing its Euro II tractors with Euro V tractors. Swire Resources is using more energy efficient LED lights in its warehouses. Cathay Pacific Catering Services has saved over 800,000 kWh of electricity by streamlining its chiller systems and optimising its ventilation control system.
