Pathways to 2050: Energy and 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
