From Green-IT to sustainable ICT

ICT plays an important role in the current days, it does not only change the way we work but also the way we live, organisations and individuals request more and more IT driven services, each day new e-applications appear and cloud computing (private or public) is present everywhere. To sustain this never ending demand, new ICT infrastructure comprising servers, storage systems, physical and wireless networks are developed.
This fast evolving change has a dual impact on the sustainability of our world. On one hand, ICT considerably helps to reduce the global environmental footprint of our society; for instance home working and teleconferencing solutions, e-commerce and e-government services clearly help in the diminishing of polluting travels. But, to operate these services, organisations more and more rely on new and powerful ICT infrastructures … that have negative environmental impacts. Huge quantities of energy are needed to feed the cloud and the datacenters; the networks and all the individual devices. Moreover, the conception of ICT equipment emits considerable CO2 equivalent emission, need precious and rare commodities and the end-of-life of these electronics equipment is far from green.
This has brought the issues of a greener and sustainable ICT to the attention of various entities including governments, NGOs, international standardization bodies, companies and individuals. The solution to this concern is commonly named Green-IT. Green-IT refers to environmentally sustainable computing. It is the study and practice of using computing resources with minimal or no impact on the environment. Green-IT strives for economic practicality and improved system performance while satisfying social and ethical responsibilities; it includes the dimensions of energy efficiency, sustainability, economics, and total cost of ownership (which includes the cost of disposals and recycling).
Green-IT is made of two interconnected domains, the greening OF IT and the greening BY IT. The greening OF IT refers to all actions taken by an organisation to make its IT more environmentally friendly by developing ecofriendly products, increasing the datacenter and IT infrastructure efficiency, reducing the paper consumption, introducing green criteria in the IT procurement and preparing for green project lifecycle and green software development. The greening BY IT refers to all IT projects and products allowing an organisation to reduce its global environmental footprint; like home working and smart work center policy, web based videoconferencing, electronic document management, e-services and applications.
It is sure that ICT has become unavoidable; making the role of Green-IT profiles pivotal to the success of green and sustainable initiatives by ensuring that the technology being used is « green » and power efficient, and by providing the IT tools and services needed to support organizations’ overall green investments. These Green-IT profiles must also help organisations in implementing a state of the art Green-IT governance in line with their corporate sustainable business development strategy.
Finally, new greening BY IT or ICT for sustainability profiles are emerging; they actively help to reach the ambitious 2020 European Commission energy target by participating in and promoting the most promising green-IT challenges like smart grids and smart cities projects and innovation 2.0 projects mixing ICT and sustainability.
So, let’s talk now about sustainable ICT profiles who will help organisations in a vital transformation from sustainable ICT to ICT for sustainability, open innovation and sustainable business models.

Can communications technologies lead to a more sustainable future ?

Investing in technology could reduce carbon emissions, encourage job creation and grow the US economy – so what’s stopping us? Asks Paul Dickinson…Last week the US government launched its latest GDP figures showing the grim reality that US economic growth has slowed. Couple this with the recently concluded negotiations in DC about raising the debt ceiling and S&P’s decision to downgrade the US’s credit rating and it’s not surprising that there is a negative cloud hanging over any reference to the economy.
There is another troubling trend: rising carbon emissions. The International Energy Agency (IEA) showed that carbon emissions grew to the highest output in history in 2010. In addition, competition for natural resources is growing fiercer by the day. According to the IEA, on average oil demand in India and China is projected to grow by over 20 million barrels a day by 2030, equivalent to using the entire US strategic oil reserves in just one month.

Sustainable growth: for a resource efficient, greener and more competitive economy

The EC and Member States are investing dramatically to overcome the economical crisis and ensure that its economy grows again. In this sense, the EU needs to improve its productivity and competitiveness. It must  maintain its early lead in green solutions, especially in the face of growing competition from China and North America. EU targets for sustainable growth include:
– Reducing greenhouse gas emissions by 20% compared to 1990 levels by 2020. The EU is prepared to go further and reduce by 30% if other developed countries make similar commitments and developing countries contribute according to their abilities, as part of a comprehensive global agreement.
– Increasing the share of renewable in final energy consumption to 20%.
– Moving towards a 20% increase in energy efficiency including in a key sector such as ICT.
