Information and Communication Technology (ICT) has a crucial role in helping to reduce Greenhouse Gas emissions (GHGs), and can be a strategic ally in the fight against climate change.

The ICT sector has mainly been viewed as a contributor to GHGs: analysts estimate that ICT constitutes between 2% and 4% of global energy use. But ICTs can be part of the solution, not just part of the problem.

It's known that ICT is an agent of, and enabler for, economic growth. But the potential role of ICTs in helping to reduce GHGs is currently poorly understood. But the ICT sector can help to reduce climate change, for example using ICT as a mode of transport, or by 'dematerialising' the economy.

I provide advice, analysis and consultancy on ICTs and climate change, and the relationship with behaviour change. During 2009-2011, I was contracted as a Senior Telecommunications Expert and as a consultant to the United Nations International Telecommunication Union, the UN's specialized agency for ICTs.

Formerly a Principal Consultant/Principal Analyst at independent ICT consultancy Ovum Ltd, with a focus on markets, strategy, policy and regulation, I was Ovum's Thought Leader on ICTs and climate change. More information at:
