Global climate change, finite fossil and nuclear resources and the vulnerability of economies and consumers to increasing and volatile prices of fossil energies are the challenges which will determine energy and climate policies for the next decades.
The Vision Scenario represents a pathway which consistently combines short- and medium-term objectives with the long-term objectives. Furthermore it is in line with the greenhouse gas emission budget, which could allow the increase of the global mean temperature to be kept to a level below 2°C compared to pre-industrial levels.
The quantitative scenario analysis of the energy system and all greenhouse gas emis-sions sources (except land use, land-use change and forestry) and of different ambi-tions in energy and climate policy outlines significantly different pathways for future energy and climate policies:
