Our Carbon Footprint: 2017

Every two years, we conduct a carbonfootprint analysis of our offices to determine the amount of greenhouse gas emissions associated with their electricity use, waste, heating fuel, employee commuting and air travel. Our latest assessment was completed in 2016, and the next one is planned for 2018. For this report, we have updated our 2016 calculations with 2017 data on air travel and offsets, and with new data on electricity use and green power purchases for some locations. Thornton Tomasetti aspires to achieve carbon-neutral business operations by 2030. In 2012, when we first began performing these analyses, we set a short-term goal of achieving a per capita carbon footprint of 4.0 metric tons of CO2 by December 2018. We surpassed this goal early, in 2016, and have continued to exceed it, achieving a carbon footprint (with offsets) of 2.9 metric tons of CO2 per employee. Between 2016 and 2017, very little change occurred in our total carbon footprint, which remains at around 3,000 metric tons of CO2 (with offsets). However, we recorded a drop in CO2 of about 400 metric tons, attributable to an increase in our purchases of green power.

Air Travel Offsets

In 2014, we began purchasing carbon offsets to neutralize greenhouse gas emissions from our business-related air travel. By donating to our offsets provider, Carbonfund.org, we support renewable energy and energy-efficiency projects that eschew the burning of fossil fuels. To ensure that we offset all our air travel, our comprehensive analysis accounts for every flight expensed by employees.

Because air travel is necessary for us to conduct essential business, we have chosen to offset its related emissions to meet our climate-neutrality goals. In 2017, we offset 1,317 metric tons of CO2 from more than 3,000 flights. This year, air travel represented 23 percent of our footprint, but through the purchase of carbon offsets, we were able to reduce its impact to zero.
