SHRP 2 L11: Final Appendices • Efficiency: Employees telecommuting two days a week can save companies 15 to 25 percent in higher productivity, as well as decrease turnover, reduce space requirements, and decrease sick-time usage by two days, resulting in a total savings per employee of an estimated $12,000 annually (71). The telecommuting program at the city of Los Angeles resulted in a $6,100 annual cost-benefit to the city per telecommuter (74). Georgia Power, Located in Atlanta implemented a pilot telecommuting program in 1992. This pilot program saved approximately $100,000 in leased office space (74). Move Media, which is located in West Hollywood, was estimated to have saved approximately $30,000 per year in reduced overhead expenses through telecommuting efforts (74). • Energy/Environment: 69. Vanpooling in the Puget Sound region, Washington, had significant environmental benefits including annual reductions in tailpipe emissions of 370 tons and annual reductions in greenhouse gases of 63,475 tons in 1999 alone (69). A study done by the Metropolitan Washington Council of Governments of four transportation emission reduction measures found that its Telework Resource Center (a program that assisted businesses in implementing telecommuting) was estimated to reduce NOx emissions by .9 tons per day, and VOC by .5 tons per day (71). A survey of an AT&T Telework Program indicates that in 2000 the program saved 5.1 million gallons of gas and also resulted in a reduction of 50,000 tons of carbon dioxide emissions (72). A 1993 US Department of Transportation study estimated that 5.2% of the work force telecommuting 3–4 days/week would save 1.1% of national fuel consumption (72). • Customer Satisfaction: BC Tel/Telus has had a ridesharing program in place since the 1970s and more than one-third of its employees participate in registered carpools. According to a survey in 2000, 98 percent of participants said they were very or quite satisfied with the carpooling program (70). • BC Hydro Telecommuting Project piloted telecommuting from October 1993 to June 1994. At the end of the pilot 100% of the telecommuters responded that they wanted to continue to telecommute while 95% of manages wanted their employees to continue with 5% being neutral (70).
