Pathways to 2050: energy & climate change

Nov 2005

The WBCSD continues 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 start stabilizing CO2 concentrations in the atmosphere at no more than 550-ppm, which relates to the “9 Gt world” described in Facts and Trends. As such, and based upon simplified assumptions and extrapolations, many choices have been made, some arbitrary, to present this single illustrative story.
In this context, biomass fuel use needs to be established and meeting over 10% of the vehicle fuel mix. in 2025.
Average on-the-road vehicle efficiency would improve by nearly 50% and a zero emissions alternative (e.g. advanced biomass fuels or hydrogen from carbon free sources) has a strong foothold in the sector (at least 10% on-the-road) by the same date.
