Summary: Economic inequality and climate change are crucial issues, with the Global North and wealthier classes being the main drivers of global carbon emissions. Reducing income inequality can help reduce carbon footprint inequalities, but it may not significantly decrease total emissions. Recomposing consumption by reducing inequalities in household expenditure and reallocating the reductions to public services can lead to significant reductions in carbon footprint on both individual country and global levels.

Summary: This study assessed the impact of climate change on building energy performance, focusing on heating consumption in a prefabricated building case study in the UK. The degree-days theory and climate change scenarios were used to predict future energy demand and CO2 emissions related to space heating. The study revealed a potential decrease in heating energy consumption for the case study building in 2030 and 2080, with the actual heating base temperature found to be lower than the standard base temperature used in the degree-days method.

Summary: This study reveals that climate adaptation can lead to higher energy demand, power system costs, and carbon prices, but the benefits of mitigation can offset decarbonization costs. Adaptation actions increase power generation capacity and costs, but in ambitious mitigation scenarios, energy system costs may be lower or even negative due to reduced adaptation needs.

Summary: China aims to peak carbon emissions by 2030 and become a carbon-neutral society by 2060. The building sector, responsible for over one-third of total carbon emissions, faces a significant challenge in helping China achieve these goals. The study conducted in Shenzhen shows that there is room for improvement in the city's energy conservation and carbon emissions reduction efforts, with the potential to reach peak carbon emissions in the buildings sector by 2025, 5 years earlier than the national target.

Summary: Flexible options are important in climate change mitigation strategies due to the high uncertainty. However, real options analysis is seldom used in building-scale investment decisions. This study proposes a decision-making framework based on real options analysis to address this research gap. The results show that climate change uncertainty does not significantly affect the optimal investment strategies, but increasing the discount rate advances the optimal investment time. The proposed framework provides guidance for mitigation strategies and offers more flexibility for investors.

Summary: This study examines the impact of climate change on precipitation and landslides in the Chania regional unit, Greece. By analyzing precipitation trends from 1955 to 2020 and investigating the extreme precipitation events in February 2019, the study reveals the increasing precipitation events that can trigger landslides due to climate change. Additionally, the study evaluates landslide susceptibility by considering the mean annual precipitation of the preceding 10 years, local hydro-geological data, and recent landslide inventory, and emphasizes the need for regular updates of the landslide susceptibility map due to ongoing changes in precipitation caused by climate change.

Summary: This study introduces a methodology for reconstructing missing daily maximum and minimum temperatures using a sparse network of meteorological stations. By combining daily observations from 15 European stations and data from two high-resolution reanalysis datasets, the reconstructed time series over the 2000-2018 period are evaluated against the observed ones. The results show that the ERA5-Land reconstructions outperform the MESCAN-SURFEX ones in terms of biases, indices, and goodness of fit.

Summary: This study focuses on the vertical wind conditions as a main external factor that limits the energy assessment of high-rise buildings in urban areas. Traditional tools for energy assessment of buildings use a universal vertical wind profile estimation, without taking into account the unique wind speed in each direction induced by the various shapes and configurations of buildings in cities. To address this limitation, the study developed an omnidirectional urban vertical wind speed estimation method using direction-dependent building morphologies and machine learning algorithms.
