SITA's energy data is recorded in our environmental management system throughout the year. It includes actual energy consumption, as well as estimated consumption based on pro-rata occupancy of locations as a tenant. All calculations are made through the environmental management system. Details of flights and the related emissions are provided annually by our travel services provider.
Managing end-of-life IT equipment
In line with the Waste Electrical and Electronic Equipment (WEEE) Directive to promote reuse, recycling and recovery of end-of-life equipment, SITA is committed to the responsible disposal of corporate hardware. We do this by using a carefully selected roster of recycling service providers who in turn ensure our IT equipment is re-used or disassembled and recycled/ disposed of in an environmentally responsible manner and within all applicable legislation. In 2015 we met our target of 100% responsible disposal at our 10 largest offices, and we continue to work toward our aim of zero electronic waste to landfill.
We also engage in responsible recycling when dealing with end-of-life equipment on behalf of our customers. Using our recycling providers, we aim to ensure that IT equipment is managed responsibly – wherever it is in the world.
SITA’s main environmental impacts have been identified as energy consumption and subsequent emissions related to normal business operations, use of materials (such as paper, print toners) and emissions from business air travel. In addition, SITA has some locations with on-site diesel storage and this is recorded as an environmental aspect.
This is less that reported in the previous year. While we were not able to collect data for some sites that were included in the 2014 data when we consider the overall intensity factors a decrease is shown. Throughout the year the benefits of the implementation of low energy lighting, reduced floor space and more energy efficient equipment continue to be realized. In July we completed a refresh on our offices in Atlanta which saw our floor space reduce. This floor space reduction has not been calculated in the overall intensity reports, but will be applied in the 2016 report against the full year data.
SITA reports on indirect emissions – those covered by scope 2 and scope 3 of the GHG protocol – including those related to the consumption of purchased electricity and transport-related vehicles outside our control.
We use DEFRA (2014) GHG factors to calculate the emissions from energy consumption from our operations, with the exception of UAE, Lebanon and Jordan where the International Energy Agency (2014) factors were used. We break down the greenhouse gases into carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O).
Emissions from air travel
Our reporting on emissions from air travel has increased, now including circa 90% of all flights booked – thanks to emissions data collection from our sites in Dubai and South Africa. The figure of 13,960.77 CO₂e for 2015 is 17.7% more than 2014 due to this additional reporting.
The flight emissions intensity figure of 0.000228 represents a 10% increase on the previous year, as a result of the expanded reporting capability. When comparing the 2014 and 2015 flight information (excluding the data from the new sites) a decrease of 0.5% in emissions is recorded.
