Since FY2011, PwC has seen the growth of its business progressively decouple from its energy consumption. The graph above highlights how over the past six years our organisation has continued to grow (# of employees), while the growth of our electricity consumption (MWh) has been slower. Our energy intensity per employee has decreased by 29%, compared to our baseline year.
We believe this trend is linked to a number of improvements in our operations which reduce our operational costs and our environmental impacts.
One of these improvements is the investment in more sustainable buildings. In recent years, we have made sure that where possible, our new offices are LEED certified. LEED is an internationally recognised green building certification that provides third-party verification that a building has been designed and built using strategies aimed at reducing energy and water usage, promoting better indoor air quality, and improving quality of life. To date, we are proud to say that we have one LEED Certified office, one LEED Silver office, nine LEED Gold offices, and one office in a LEED Platinum building.
We have also searched to find new ways to reduce our energy consumption in existing workspaces. In 2015, with the support of local government subsidies, we rolled out a pilot project to progressively upgrade the lights in our Beijing office to LED lighting. Unlike older forms of lighting, LED lights are more energy efficient, have a longer lifespan, and are more ecologically friendly than fluorescent or incandescent lamps. Due to the success of this pilot project, we are now looking into opportunities to upgrade some of our other offices including in Shanghai and Hong Kong.
Another significant contributor to our reduction in energy intensity is the adoption of hotelling. Hotelling is a more flexible approach to office management, where our staff no longer have assigned seats but instead check-in to an office or workspace for a certain duration of time and then check-out when they leave. This has also given the opportunity for us to reduce the size of individual work stations so we can house more people in dynamic and collaborative environments.
Combined, these innovations and upgrades allow us to reduce our impacts on the environment and are aligned with our commitment to measure and manage our environmental impacts.
