Our company’s environmental sustainability vision and strategy are set by a cross-functional team, sponsored by our Executives, with annual oversight by the Board of Directors. This group has directed our focus on the three areas most relevant to our business: water, energy and materials.

In 2014, we achieved carbon neutrality. First we reduced our operational carbon footprint and then funded external renewable energy and offset projects to neutralize the rest of the emissions from sources associated with our business. These included internal operations, purchased electricity, employee commuting and business travel, and suppliers of products and services.

In addition to achieving carbon neutrality, we have set bold environmental milestones for 2020.

Our operational carbon intensity goal is to reduce Scope 1 and Scope 2 GHG emissions intensity by 80 percent by 2020 compared to our 2006 baseline and normalized by revenue. This is equivalent to maintaining 2006 levels of carbon emissions, despite realized and anticipated business growth. Reducing our operational carbon emissions will help us maintain our carbon neutral status.

Our water intensity goal is to reduce our water use by 80 percent by 2020 compared to 2006, normalized by revenue.

For waste, our goal is to achieve zero waste-to-landfill. In 2012, we achieved virtually zero-waste-to-landfill, which is defined as a landfill diversion rate of 98 percent or greater. We also are in the process of developing a new water intensity goal that we plan to release in 2015.

When it makes sense, we also pursue Leadership in Energy & Environmental Design (LEED) certification for some of our owned and leased facilities. We currently operate four energy-efficient buildings with LEED certification. These include two LEED Platinum buildings, one in Weston, Mass. and one in Cambridge, and two Gold certified buildings, including our headquarters in Cambridge, Mass. and a facility in RTP, N.C.
