AT&T continues to improve technical efficiency as a means toward reducing its environmental impact, according to its 2008 CSR report.

Above is a look at AT&T’s data center initiatives.

Over the past year, AT&T has:

recorded a 43 percent increase in accessories and batteries reused or recycled from 2007 to 2008, resulting in 1.3 million pounds diverted from the landfill.
added a 1 megawatt solar system to its San Ramon, Calif., facility.
prevented 75 million pounds of scrap materials from landfills.
reduced cell site electricity consumption 289 million kilowatt hours, saving more than 200,000 tons of CO2 emissions, by reducing the amount of dual networks.
identified up to 188 central office switches for consolidation, due to low utilization. This has the potential to save up to 49 million kWh annually.
introduced economizers at sites to circulate ambient air and reduce energy costs.

AT&T’s 2009 goals include:

have all suppliers read AT&T’s Citizenship & Sustainability Principles of Conduct for Suppliers by the end of the year.
reduce electricity consumption, relative to data growth on the network, by 15 percent over 2008.
by 2019, replace about 8,000 gasoline-powered service vehicles with alternative fuel models, as well as 7,000 passenger cars.
swap out cell tower light controllers and incandescent bulbs at nearly 3,500 sites. The replacement LEDs can operate maintenance-free for 10 years and use 10 percent of the energy of incandescents.

The report did not detail AT&T’s emissions for 2008.
