Although environmental impacts are driven by human activities in specific regions, these impacts often manifest elsewhere due to the globalized nature of environmental systems and human.
Recent changes in ICT use globally have damaged the environment (in terms of waste and energy consumption etc.) but also have the potential to support environmental sustainability activities, [2] such as the targets set within the Millennium Development Goal (MDG) number 7 (MDG7) to "ensure environmental sustainability".

Computable general equilibrium (CGE) models are a class of economic models that use actual economic data to estimate how an economy might react to changes in policy, technology or other external factors. CGE models are also referred to as AGE (applied general equilibrium) models. A CGE model consists of equations describing model variables and ...
