The United States and China have unveiled a secretly negotiated deal to reduce their greenhouse gas output, with China agreeing to cap emissions for the first time and the US committing to deep reductions by 2025.
The pledges in an agreement struck between President Barack Obama and his Chinese counterpart, Xi Jingping, provide an important boost to international efforts to reach a global deal on reducing emissions beyond 2020 at a United Nations meeting in Paris 2015.
China, the biggest emitter of greenhouse gases in the world, has agreed to cap its output by 2030 or earlier if possible. Previously China had only ever pledged to reduce the rapid rate of growth in its emissions. Now it has also promised to increase its use of energy from zero-emission sources to 20% by 2030.
The United States has pledged to cut its emissions to 26-28% below 2005 levels by 2025.
The European Union has already endorsed a binding 40% greenhouse gas emissions reduction target by 2030.
Why data centers matter
Data centres use in the region of 2.2-3.3% of Britain's total grid power. While that is a considerable amount, ICT has been repeatedly identified as a key mechanism through which our society will reduce carbon emissions. The World Wildlife Fund has identified ICT as the way to "save the first billion tonnes" of carbon, and the Global eSustainability Initiative SMART 2020 report has identified how the intelligent application of ICT can reduce our annual global emissions by 15% by 2020.
Data centres lie at the heart of ICT's potential to reduce our collective carbon emissions.
Need for outsourcing
Outsourcing a corporate data centre or entire ICT department would, under the current allocation approach, result in the carbon also being outsourced. While clear 'carbon dumping' could otherwise lead to reputational damage, data centre outsourcing is a common practice to help companies reduce their carbon liability.
Energy Efficiency Practices at Telehouse recommended by the Experts
Industry experts recommend encouraging first and foremost efficient use of IT devices, as they can turnover quickly and deliver rapid improvements. Telehouse provide a wide portfolio of energy efficient hardware.
Data centers with free cooling, lowering Power Usage Effectiveness (PUE)
Buying low-carbon electricity powering the data center
Use of energy efficient lighting systems throughout the data center
Cold aisle containment employed to improve cooling efficiency
Adiabatic cooling used to adjust the airflow to control temperature
Variable speed pumping systems used in our chillers, fans and UPS filter drives
High power Busbars used for the safe and efficient distribution of electricity
Energy monitoring systems to identify supply and deviation
