Facts tagged with Greenhouse Gases
Estimates of potential reductions in greenhouse gasses vary from 1 billion tons over 10 years to almost 8 billion metric tons in 2020.
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)
The net greenhouse gases that are now being saved due to the decline in postal volume is equal to 1.4 million tons of greenhouse gas. (p. 32)
The greenhouse savings from eliminating CDs can be roughly estimated by calculating the oil saved by not producing these CDs.
By one estimate, recycling a ton of plastic saves 685 gallons of oil. (p. 30)
As previously noted, around 10% of workers telecommute full time, approximately one-tenth of these economic and environmental costs are already being saved, which approximates an annual reduction of 45 million tons of greenhouse gases. (p. 24)
If 10% more of the workforce could telecommute fulltime, emissions of greenhouse gases into the atmosphere would be reduced by an additional 42.4 million tons of carbon dioxide, as well as 2.6 million tons of other pollutants, which results in 45.0 million fewer tons of greenhouse gases each year. (p. 24)
The direct emission reductions of one billion tons of CO2 which could be achieved [through smarter use of IT, such as city planning, smart buildings, smart appliances, process optimization, smart work and intelligent transportation] … is equivalent to approximately a quarter of EU’s current CO2 emissions.
Based on estimates by Jupiter that assume that B2C sales will increase by 71% over a five-year period ending 2011
(approximately an annual rate of 11%), “it is reasonable to assume that the growth rate of total online commerce will slow somewhat – only doubling over the next ten years – and produce an average savings in greenhouse gas emissions equal to 3.8 million tons per year in total e-commerce. Based on this scenario, the ten-year incremental cumulative effect of e-commerce growth on avoiding greenhouse gas production is estimated to be 206.3 million tons.” (p. 12)
For every billion square feet of retail space saved, 8.49 million tons of greenhouse gases will not be emitted. (p. 9)
