How IT Can Cut Carbon Emissions
Came across a paper from McKinsey which talks about how IT can cut its carbon footrpint.
The rapidly growing carbon footprint associated with information and communications technologies, including laptops and PCs, data centers and computing networks, mobile phones, and telecommunications networks, could make them among the biggest greenhouse gas emitters by 2020. However, our research also suggests that there are opportunities to use these technologies to make the world economy more energy and carbon efficient. An analysis of five groups of abatement opportunities finds that such technologies could help to eliminate 7.8 metric gigatons of greenhouse gas emissions annually by 2020 equivalent to 15 percent of global emissions today and five times more than our estimate of the emissions from these technologies in 2020.
About the role of ICT in cutting emissions:
Information and communications technologies can help abate far more emissions in the general economy their own production and use generates. We estimated this abatement potential by studying all known opportunities to optimize energy productivity in four sectors—buildings, power, transport, and manufacturing. Then we calculated the specific energy savings and the associated abatement potential for one significant group of opportunities in each of the sectors. We also looked at a set of opportunities that cut across sectors:
telecommuting and other technological substitutions for emission-producing activities. In just these five areas, we identified annual reductions of 7.8 metric gigatons of carbon emissions by 2020. Because we did not review all prominent opportunities to reduce them—for example, we excluded satellite surveillance to monitor deforestation and herding, two of the largest contributors to climate change—the full impact of information and communications technologies could be much greater.
