In its first-ever corporate sustainability report, Deloitte Touche Tohmatsu reveals that it used more than 308 million kilowatt hours of electricity in 2008, or about 2.59 megawatt hours per employee.
The company derived the above and below figures based on reporting from 15 large member firms, out of 35 total member firms. Those 15 firms generated 1.31 metric tons of GHG emissions per employee, or 155,860 metric tons total, according to the report (PDF).
Business air travel among the 15 large firms totaled 1.694 billion kilometers, or about 14,220 kilometers per employee. That amounts to more than 197,000 metric tons of CO2 in total, and 1.66 metric tons of CO2 per employee.
In total, the firm has 168,000 employees in 140 locations.
Various Deloitte offices are trying different methods to reduce the company’s impact on emissions from commuting.
Deloitte Germany, for instance, has a tiered incentive program that sets a minimum efficiency level. Cars that do not surpass a higher threshold must pay about $3,000. By choosing a high-efficiency model, however, partners and directors can get a one-time bonus of about $6,000.
Deloitte offices in the UK and Belgium have set emissions standards for fleet vehicles, meanwhile.
Elsewhere throughout Deloitte operations, there are a range of efforts to reduce energy and water use.
Deloitte Netherlands gets about 60 percent of its electricity from renewable sources.
