Decoupling: Conditions for Stabilizing Climate and Efficiency Gains

This lecture explores the conditions required for decoupling greenhouse gas emissions in Swiss aviation, using the IPAT+Kaya framework to understand the necessary efficiency gains and energy substitutions to stabilize the climate. It delves into the limitations of the IPAT decomposition and analyzes the growth rates of emissions, the relationship between passengers and emissions, and the drivers of CO2 emissions. The lecture also covers the Kaya decomposition for CO2, the impact of efficiency improvements on growth, and the objectives for reducing CO2 emissions. Additionally, it discusses the finer decomposition of CO2 emissions, provides examples of Kaya decomposition, and highlights the limitations of IPAT decomposition, emphasizing the interconnectedness of its components.
