IPAT and Kaya: Decoupling Environmental Impacts

This lecture by the instructor explores the concepts of IPAT and Kaya to understand how to decouple environmental impacts from rising affluence. It delves into CO2 emissions from Swiss aviation, growth rates of emissions, relationships between variables like passengers and emissions, and the Kaya decomposition for CO2. The lecture also discusses the cancellation of efficiency improvements by growth, the drivers of changes in CO2 emissions in OECD and non-OECD regions, and the necessary reduction in CO2 intensity of GDP for climate stabilization. Limitations of IPAT decomposition are highlighted, along with lessons learned on the challenges of offsetting economic and population growth to reduce environmental impacts.
