An important question for climate policy making is how much GHG emissions and energy can be saved, in which sectors and at what costs? Traditionally, studies looking at this question are often characterised as either using a Bottom-Up or a Top-Down approach. The differences between these approaches are far from clear-cut. The first approach tends to focus more on available technologies and their characteristics, while the second approach focuses on the processes within the economy as a whole on the basis of observed historic behaviour. The two approaches have also been used in the IPCC fourth assessment report (AR4) (IPCC, 2007) in order to assess the medium- term (2030) sectoral potentials and costs of GHG emission reduction. AR4 finds that at the global level the total emission mitigation potentials and costs of the two approaches are comparable (and presents both results in the summary for policymakers). However, at a regional and sectoral scale, the results could not be readily ...

Der Bericht stellt die Neuauflage der Weltenergie-Szenarien dar, die das Institut für Technische Thermodynamik des Deutschen Zentrums für Luft- und Raumfahrt (DLR) zusammen mit über 30 weiteren Experten im Auftrag von Greenpeace International und dem European Renewable Energy Council (EREC) erarbeitet haben. Die Weltenergie-Szenarien „Energy [R]evolution 2010“ zeigen, wie die globalen CO2-Emissionen von heute 30 Milliarden Tonnen pro Jahr bis zur Mitte des Jahrhunderts auf rund zehn Milliarden Tonnen pro Jahr gesenkt werden können. Diese drastische Reduktion der Treibhausgase ist notwendig, um den Anstieg der globalen Durchschnittstemperatur auf zwei Grad Celsius gegenüber dem vorindustriellen Niveau zu beschränken. Gegenüber der letzten Studie geht ein zweites Advanced Energy [R]evolution Szenario noch einen Schritt weiter: Sollte diese CO2-Minderung aufgrund bisher nicht berücksichtigter langfristiger Klimaeffekte die Klimaerwärmung nicht aufhalten, so können zusätzliche Reduktion...

A sustainable energy supply can be achieved, even under conditions of global economic growth - this is the outcome of the updated global energy scenario developed on behalf of Greenpeace International and the European Renewable Energy Council (EREC) by the Institute of Technical Thermodynamics (Institut für Technische Thermodynamik) of the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) in cooperation with over 30 other scientists and institutes. The global energy scenario - the so-called Energy [R]evolution Scenario - shows how global CO2 emissions can be reduced from 30 billion tonnes per year today to about ten billion tonnes per year by 2050. This drastic reduction of greenhouse gas emissions is necessary to ensure that the rise in the global average temperature relative to the pre-industrial level does not exceed two degrees Celsius. The study shows that these goals can in fact be compatible with access to electricity for people around the world, a reli...

The Fourth Assessment Report of IPCC reports that greenhouse gas emissions can be reduced by about 30–50% in 2030 at costs below 100 US$/tCO 2 based on an assessment of both bottom-up and top-down studies. Here, we have looked in more detail into the outcomes ...
