Toward Reducing The Greenhouse Gas Emissions Of The Internet And Telecommunications
Amid growing concern over the surprisingly large amount of greenhouse gas produced by the Internet and other telecommunications activities, researchers are reporting new models of emissions and energy consumption that could help reduce their carbon footprint. Their report appears in ACS’ journal Environmental Science & Technology.
Researchers from the Centre for Energy-Efficient Telecommunications (CEET) and Bell Labs explain that the information communications and technology (ICT) industry, which delivers Internet, video, voice and other cloud services, produces more than 830 million tons of carbon dioxide (CO2), the main greenhouse gas, annually. That’s about 2 percent of global CO2 emissions — the same proportion as the aviation industry produces.
A new way to estimate Internet and telecommunications energy use may reduce the industry’s
carbon footprint.
They describe development and testing of two new models that better estimate the energy consumption and CO2 emissions of Internet and telecommunications services. They tested the models on a simulated network and on a deployed network that serves the majority of schools in California. Both models delivered better estimates than the current “top-down” models. The researchers suggest, based on their models, that more efficient power usage of facilities, more efficient use of energy-efficient equipment and renewable energy sources are three keys to reducing ICT emissions of CO2.
CEET is a partnership between Alcatel-Lucent, the University of Melbourne and the Victorian State Government. It is the world’s first research center exclusively dedicated to energy-efficient telecommunications technologies. Its research efforts cover a broad range of telecommunications network infrastructures and how those elements can increase their energy efficiency.
