Technical pathways to deep decarbonization in cities: Eight best practice case studies of transformational climate mitigation

Samantha Linton et al.

Summary: With the increasing urgency for climate action, local governments and stakeholders are working towards deep decarbonization and committing to significant greenhouse gas reductions by 2050. Urban areas are the largest source of greenhouse gas emissions, and local governments have control over a large proportion of emissions. However, there is a lack of knowledge about the technical and policy pathways for deep decarbonization and how they differ for cities of different sizes. The study analyzed deep decarbonization plans of cities ranging from eight thousand to nine million people, finding unique priorities and innovative strategies among them. The emerging technical pathways focus on priority sectors like electricity, buildings, transportation, waste, and carbon sinks, but some cities are expanding their plans to include new areas in GHG mitigation.

Reducing fossil fuel-based generation: Impact on wholesale electricity market prices in the North-Italy bidding zone

Marco G. Flammini et al.

Summary: This paper presents a methodology for simulating future electricity wholesale prices by considering hourly electricity generation offers datasets. Machine learning, clustering, and distribution sampling techniques are used in estimating prices distribution in 2030 in the Italian market. The approach bypasses the need for access to all transactions of a given market, achieving similar results using probability distributions.

Climate change adaptation in Cambodia's coastal hotel sector: An analysis of adaptation measures and hotel characteristics

Tinat Nhep et al.

Summary: After decades of challenges, Cambodia has enjoyed stability and a flourishing tourism industry, but is vulnerable to climate change, which threatens its economic development. Sustainable Development Goal 13 'Climate Action' is crucial for Cambodia's coastal tourism sector, but adaptation actions in hotels vary, with larger hotels showing stronger responses than budget and Khmer-owned ones.

Energy system transformations and carbon emission mitigation for China to achieve global 2 °C climate target

Guangpu Zhao et al.

Summary: The study finds that in order to achieve the global 2-degree Celsius goal, China's carbon emissions need to peak in 2023 and decrease to 3.56 GtCO(2) by the mid-century. During the period from 2020 to 2050, the power sector will bear the largest responsibility for emissions reduction, with primary energy consumption needing to peak before 2040 and the remaining carbon budget of 235 GtCO(2) needing to be controlled.

Assessing the adequacy of the global response to the Paris Agreement: Toward a full appraisal of climate ambition and action

Marta Torres Gunfaus et al.

Summary: This commentary puts the international climate governance assessment in the context of a comprehensive framework for assessing the global response to the Paris Agreement. It suggests ways to advance global governance assessments and highlights the importance of the sectoral systems approach and integration of multiple levels of governance and short- and long-term time horizons.

Analysis of occupant behaviour in the use of air-conditioners in public buildings in developing countries: evidence from Ghana

Divine Kwaku Ahadzie et al.

Summary: This study examines occupant behaviors related to efficient use of air-conditioners in public buildings in Kumasi, Ghana. Findings suggest that switching on fans as an alternative had the most positive impact on energy consumption, followed by opening windows for natural ventilation, while turning off ACs when leaving the room had the least impact. The theory of planned behavior was validated in this model, emphasizing the importance of behavioral attitude and subjective norm in influencing occupant behaviors.
