Greenhouse gas emissions
Through our materiality assessment, we identified the wider impacts of a changing climate and greenhouse gas (GHG) emissions as our most significant environmental issue – for our own performance and across our value chain.
We believe businesses can become more resilient by identifying and adapting to climate change risks in their value chain. We are therefore leading the way in the development of methodologies for companies to use for this purpose. As an example, we co-authored a report with the World Business Council for Sustainable Development (WBCSD) entitled Building Resilience in Global Supply Chains that includes a number of case studies to illustrate the value of this approach to clients.
We strive to grow our business while reducing our GHG emissions per employee. In FY16, we saw a decrease of 2 percent in our emissions intensity, from 5.0 tCO2e emissions per FTE down to 4.9 tCO2e emissions per FTE.
Our total GHG emissions fell to 22,736 tCO2e in FY16, a decrease of 1.3 percent from 23,026 tCO2e in FY15. Our largest source of GHG emissions is business travel, accounting for 54.5 percent of total emissions. GHG emissions from energy consumption, including electricity and fuel consumption in buildings in which we lease office space, account for 24 percent of total emissions. This includes GHG emissions associated with heating, ventilation and cooling systems, and shared and common areas of our offices. Direct office electricity and fuel consumption accounts for 20.3 percent of total emissions.
The nature of our business often requires our people to travel significant distances to undertake work for clients. Where possible, we focus our efforts on using more environmentally friendly modes of transport to client sites, and on continuing to reduce the amount of travel associated with internal meetings. For example, we continue to invest in technology that enables meetings and other forms of engagement to be conducted via video conferencing and other virtual tools.
In FY16, we generated 12,398 tCO2e emissions via business travel, a 2.6 percent decrease from FY15. The majority of these emissions resulted from air travel, which accounts for 66.6 percent, or 8,257 tCO2e, of our business travel emissions.
