Primary environmental data covers 83% of floor space. Non-reporting locations include small serviced offices from which it is difficult to collect accurate data. To ensure reporting on the full extent of our environmental impact, we estimate energy consumption, water usage and waste disposal at these locations, based on our primary environmental data.

Our car fleet constitutes nearly half of our Scope 1 emissions. Through the expanded coverage of green car policies at a local level, we increased the global average car efficiency (123g/ km in 2015 from 127g/ km in 2014). This helped to achieve a 48% reduction in car fleet emissions since 2010. Reed Messe Wien exhibition and conference centre has 23 charging stations for electric vehicles, making it one of the largest recharging stations in Austria.

Total Scope 1 emissions decreased by 17% from 2014, due primarily to mild weather across North America where we have the majority of our offices. We continue the overall trend of reducing Scope 1 emissions (43% between 2010 and 2015).

Scope 2 (gross) emissions are responsible for the greatest share of operational GHG emissions. Efficiency projects in data centres and office locations and continued consolidation of space achieved a 35% reduction in absolute terms and 34% in emissions intensity since 2010.

Scope 3 business travel data is collected through our travel provider, BCD, and covers 90% of our operations by revenue. We use the radiative forcing (RF) emissions factors provided by the Department for Environment, Food & Rural Affairs for calculating business travel emissions which take account of the full environmental impact of air travel (e.g. water vapour, contrails, nitrogen oxide emissions, etc.). We continue to promote travel alternatives such as videoconferencing; in 2015, we held more than 10,800 meetings via videoconference, including through new desktop videoconferencing facilities.

Our Climate Change Statement indicates our support for the globally recognised target of an 80% absolute reduction in CO2 emissions by 2050. It also outlines our commitment to mitigation and adaptation and our belief in the need for an ambitious, robust and equitable policy on climate change. As such, we continue to engage with governments on climate change regulation. As an endorser of the UN Global Compact’s Caring for Climate and through the European Network for Sustainable Business, we share good practice with others and support voluntary codes of practice.
