“…The scenario development has clearly demonstrated that developments in China and India also have a major impact on global energy change. While China is already taking a leading position in several transformation processes, but the speed of its actions is not yet sufficient to achieve long-term goals [60].…”

It is still possible to comply with the Paris Climate Agreement to maintain a global temperature ‘well below +2.0 °C’ above pre-industrial levels. We present two global non-overshoot pathways (+2.0 °C and +1.5 °C) with regional decarbonization targets for the four primary energy sectors—power, heating, transportation, and industry—in 5-year steps to 2050. We use normative scenarios to illustrate the effects of efficiency measures and renewable energy use, describe the roles of increased electrification of the final energy demand and synthetic fuels, and quantify the resulting electricity load increases for 72 sub-regions. Non-energy scenarios include a phase-out of net emissions from agriculture, forestry, and other land uses, reductions in non-carbon greenhouse gases, and land restoration to scale up atmospheric CO2 removal, estimated at −377 Gt CO2 to 2100. An estimate of the COVID-19 effects on the global energy demand is included and a sensitivity analysis describes the impacts if implementation is delayed by 5, 7, or 10 years, which would significantly reduce the likelihood of achieving the 1.5 °C goal. The analysis applies a model network consisting of energy system, power system, transport, land-use, and climate models.

“…Previous systematic reviews on zero-carbon transitions have tended to focus on a specific region, sector, or mitigation option. For example, Xiao, Simon and Pregger (2019) investigate policies on transitioning coastal China to net-zero, Kourgiozou et al (2021) examine the discourse around decarbonising the education sector, and Martin, Agnoletti and Brangier (2020) explore the literature on hydrogen as an energy source. There is an absence of reviews covering the breadth of options for facilitating zero-carbon transitions more generally.…”

Academia has a crucial role to play in informing urgently needed actions on climate mitigation. It is vital to understand what is known about the potential contribution of climate mitigation options, the barriers that exist to achieving that contribution, and to quantify the research balance and geographic focus of these various approaches across the literature. This PRISMA-based systematic literature review aims to provide the reader with the following: Firstly, an overview of the post-Paris climate mitigation research landscape and secondly, an assessment of the climate mitigation potential of those options per the literature reviewed. Analysis of the research landscape demonstrated that supply-side research greatly outnumbers that on the demand-side, which totalled just half of that which focused on the supply-side. In terms of the geographic scale, the reviewed literature was dominated by national-level studies, with sub-national studies the least common, particularly those at a local government level. Given this, it can be concluded that two key areas would benefit from further research–that focusing on demand-side mitigation, and that carrying research out at more local levels. On climate mitigation potential, wind and solar energy were found to be the biggest contributors to a decarbonised energy supply, across a range of study areas. Discrepancies were identified between findings in the academic and grey literature for several options, chiefly bioenergy and nuclear power: bioenergy made significantly higher contributions in the academic literature versus grey literature, with the opposite true for nuclear. Demand-side options all demonstrated significant mitigation potential in the literature reviewed but received very limited coverage in comparison to many of their supply-side counterparts. Future research should pursue this knowledge gap to reach a better understanding of the contributions they can make and ensure that policymakers have the data necessary to chart a course to a zero-carbon future.

“…With the rapid development of urbanization in China, land resources are becoming increasingly scarce, and building density and height in urban residential districts are rapidly increasing [1,2]. High-density residential districts exhibit reduced ventilation and heat dissipation conditions, thus leading to low wind velocity environments and poor thermal comfort in residential districts [3].…”

A comfortable wind environment favors the sustainable development of urban residential districts and public health. However, the rapid growth of high-rise urban residential districts leads to low wind velocity environments in summer. This study examines the influence of enclosure boundary patterns and lift-up design on the wind environment and proposes an optimization strategy to improve the low wind velocity environment in residential districts in summer. A typical residential district in Hangzhou was selected; the average wind velocity, calm wind zone ratio and comfortable wind zone ratio were selected as the evaluation indexes. The wind environment for different enclosure boundary patterns and lift-up designs were obtained via computational fluid dynamics (CFD) simulations. The results indicate that the pedestrian wind environment is greatly improved in residential districts by reducing the height/width of the enclosure boundary, increasing the permeability rate and adopting a lift-up design in all buildings within residential districts. A combination of permeable railings and lift-up design is recommended; this can increase the average wind velocity and the ratio of comfortable wind zones by 70% and 200%, respectively. This study provides practical guidelines for the optimization of a low wind velocity environment in Chinese high-density residential districts in summer.
