O2 to cut emissions from data centres through energy efficiency improvements

O2 has announced that they have invested in innovative energy-efficient cooling equipment to regulate the temperature of data centres and core network sites. These will replace traditional electric-powered air conditioning and transitional gas-based refrigeration.

In 2016, it was reported that the world’s data centres used more than Britain’s total annual electricity consumption – 416.2TWh, significantly higher than the UK’s 300TWh. This was equivalent to 3% of global electricity demand and, with the grid mix at the time taken into account, around 2% of annual global emissions.

O2 estimates that each site with the new technology will consume 15-20% less energy every year. To date, around 70% of the firm’s sites have received the upgrade. Once all sites receive the technology, O2 forecasts, CO2e savings of more than 678,000 kilograms will be delivered within a 12-month period.
