Broadband will reduce greenhouse gas emissions by more than 1 billion tons by 2018 – equivalent to reducing oil imports by 11 percent.
Broadband-enabled IT applications reduce energy consumption and cut greenhouse gas emissions.
Broadband is already contributing to greater energy efficiency. Broadband applications will reduce greenhouse gas emissions by more than a billion tons by 2018.
Prior and during the commercialization of the Internet (1992-1996), GDP growth averaged 3.2% a year, whereas energy demand grew 2.4% and carbon dioxide emissions grew by 2%.
In contrast, in the years when Internet use grew exponentially and became mainstream (1996-2000), GDP growth averaged 4% per year, while energy demand grew only 1% a year and carbon dioxide emissions grew only slightly above 1%.” (p. 43)
If only 10 percent more of the workforce regularly teleworked - roughly a doubling of today’s percentage - greenhouse gas emissions would be reduced each year by an additional 42.4 million tons of carbon dioxide, as well as 2.6 million tons of other pollutants.
Over a 10-year period, the direct and indirect benefits of this additional telecommuting would prevent more than a half-billion tons of added pollutants from being released into the atmosphere and generate direct savings of “$96.5 billion, including the cost of 4.4 billion gallons of gasoline each year.”
The National Science Foundation, has over half of its employees teleworking, and reports that 87 percent of employees view teleworking positively.
Importantly, 87 percent of managers report that the productivity of teleworking employees remains level or even increases. In addition, by not commuting, on average “each NSF teleworker reclaims 62 hours of their lives and saves $1,201 a year. Extrapolating those savings across the agency, NSF teleworkers collectively spare the environment over 1 million pounds of emissions and save more than $700,000 in commuting costs per year.”
The U.S. Office of Personnel Management reports that of the 1.25 million federal workers who are eligible to telework, only 9 percent actually do.
These teleworkers comprise just 6.12 percent of the total federal workforce. In 2006, the number of federal employees who teleworked actually dropped 7.3 percent to 110,592 from 119,248 in 2005, while the number of employees categorized as not eligible for telework leaped from 30 to 44 percent.
Only 2 percent of the American workforce are full-time teleworkers, although 28.7 percent of employees work at home at least one day per month, and 44.8 percent have worked from home at some time.
The Consumer Electronics Association estimates that using electronics such as personal computers and wireless networks to telecommute saves the equivalent of 9 to 14 billion kilowatt-hours of electricity per year.
(equal to the amount of energy used by approximately 1 million U.S. households every year); and could eliminate carbon dioxide emissions in an amount equal to taking 2 million cars off the road.
Teleconferencing could reduce greenhouse emissions by 199.8 million tons
...if 10 percent of airline travel could be replaced by teleconferencing over the next 10 years.
Based on conservative assumptions, “the elimination of CDs will save the equivalent of 42 million gallons of oil”.
Because there is 22 pounds of carbon per gallon of oil,121 there are 0.5 million tons of emissions that could be saved. If this savings could be realized in the next ten years, the cumulative savings from eliminating plastic CD cases would be 2.5 million tons of greenhouse gas emissions. (p. 31)
