Air-conditioning adoption and electricity demand highlight climate change mitigation-adaptation tradeoffs.

We elucidate mid-century climate change impacts on electricity demand accounting for endogenous adoption of residential air-conditioning (AC) in affluent, cooler countries in Europe, and in poorer, hotter states in India. By 2050, in a high-warming scenario (SSP585) AC prevalence grows twofold in Europe and fourfold in India, reaching around 40% in both regions. We document a mitigation-adaptation tradeoff: AC expansion reduces daily heat exposures by 150 million and 3.

Increased energy use for adaptation significantly impacts mitigation pathways.

Climate adaptation actions can be energy-intensive, but how adaptation feeds back into the energy system and the environment is absent in nearly all up-to-date energy scenarios. Here we quantify the impacts of adaptation actions entailing direct changes in final energy use on energy investments and costs, greenhouse gas emissions, and air pollution. We find that energy needs for adaptation increase considerably over time and with warming.

Assessment of the effectiveness and efficiency of packaging waste EPR schemes in Europe.

This paper provides an analysis of the performance of European packaging waste systems, focusing on Extended Producer Responsibility schemes and Producer Responsibility Organizations. We adopt two separate but complementary empirical analysis: i) an indicator-based assessment of the cost-efficiency and recycling effectiveness of PROs; ii) a regression analysis of the determinants of recycling rates at the national level. The analysis spans over 25 national schemes and 21 Producer Responsibility Organizations.
