Pathways to 2050 - Energy and Climate Change
12 the future of Energy    1/20/2006 6:55:28 AM

Pathways to 2050 - Energy & climate change builds on the WBCSD’s 2004 Facts and Trends to 2050: Energy and Climate Change and provides a more detailed overview of potential pathways to reducing CO2 emissions.

The pathways shown illustrate the scale and complexity of the change needed, as well as the progress that has to be made through to 2050. Our “checkpoint” in 2025 gives a measure of this progress and demonstrates the urgency to act early to shift to a sustainable emissions trajectory.

The WBCSD has chosen to continue to illustrate the challenges associated with one particular trajectory, consistent with the discussion already presented in Facts and Trends. This document therefore looks closely at the changes needed to begin to stabilize CO2 concentrations in the atmosphere at no more than 550-ppm (see glossary), which relates to the “9 Gt world” described in Facts and Trends. As such, and based upon simplified assumptions and extrapolations, we have made many choices, some arbitrary, to present this single illustrative story. It is neither a fully-fledged scenario nor does it recommend a target. Moreover, this document does not discuss policy definitions or options, topics that need to be dealt with separately.

Our principal sources of data for 2002 and 2025 references have been the IEA World Energy Outlook (IEA 2004) and the IEA CO2 Emissions From Fuel Combustion 1971-2002 (IEA 2003). While the projections we have made in Pathways to 2050 also build on the findings of Facts and Trends, the reader may note some differences in the numbers presented in some areas. These are a result of improved data sources and some adjustments in our own calculation and transcription methods, but do not alter the key findings and outcomes.

This document is intended to stimulate dialogue and enhance mutual understanding of the issues. We hope many will share our own belief that widespread action must start now.
