Abstract

This report provides a high-level summary of the transformational scenario pathways developed by the IIASA Energy Program within the framework of the Global Energy Assessment (GEA). These pathways approach the global transition toward sustainable development in an integrated, holistic manner, taking a broad view of the four main energy challenges faced by society in the 21st century: providing universal access to modern energy for all; avoiding dangerous climate change; reducing the impacts of energy on human health and the environment; and enhancing energy security. Developing solutions to these challenges is one of the chief aims of policy makers, and for this reason this report attempts to synthesize a multitude of strategic insights that have resulted from the pathways analysis. The overarching objective of the report is to provide guidance on how to facilitate the transformation of the energy system to achieve the multiple energy objectives. Focus is given to the required pace of the transformation at both the global and regional levels, as well as to the types of measures that will be needed to ensure a successful transition.

This report is complemented by three interactive, web-based analytical tools, which have been developed by the IIASA Energy Program in support of this study: (1) the GEA Scenario Database, which documents the full suite of transition pathways in great detail, allowing the user to explore the consequences of different supply and demand-side technology choices for the feasibility and costs of reaching the multiple energy objectives at both the global and regional levels; (2) the IIASA ENE-MCA Policy Analysis Tool, which permits the concurrent assessment of synergies and trade-offs between the multiple energy objectives at the global scale; and (3) the IIASA Energy Access Tool (ENACT), which helps gauge the effectiveness of various energy access policies and measures in the major developing regions of the world.
