The 2014 Energy and Climate Outlook provides an integrated assessment of how human activities, given current development path, are interacting with complex Earth systems and ultimately affecting the natural resources on which depend. It uses a projection modeling system developed by MIT’s Joint Program on the Science and Policy of Global Change, the Integrated Global Systems Model (IGSM) framework, to determine the associated energy, climate, atmosphere, ocean, and land-use implications. A principal product of this outlook is a detailed set of economic, energy, land use, water stress, and emissions projections for each of the 16 major countries or regions of the world, through the year 2050.
