Technologies that are discussed controversially today may be
needed to keep the future risks and costs of climate change in check. Combining
the production of energy from fossil fuels and biomass with capturing and
storing the CO2 they emit (CCS) can be key to achieving current climate policy
objectives such as limiting the rise of the global mean temperature to below 2
degrees Celsius. This is shown by the most comprehensive study to date on
technology strategies to combat climate change, published in a special issue of
the journal Climatic Change. It is based on the analysis of 18 computer models
by an international team of scientists under the roof of the Stanford Energy
Modelling Forum (EMF 27).
