Impacts of climate change, population growth, and power sector decarbonization on urban building energy use
This study quantifies mid-21st century hourly building energy use in 277 urban areas in the USA, revealing spatially and temporally heterogeneous changes influenced by future climate, population dynamics, and electric power sector decarbonization.

A net-zero emissions strategy for China’s power sector using carbon-capture utilization and storage
This study indicates that allowing up to 20% abated fossil fuel in China’s power generation system could reduce the power shortage rate by up to 9% in 2050, and increase system resilience during weather events relative to a zero fossil fuel system.

The narrowing gap in developed and developing country emission intensities reduces global trade’s carbon leakage
International trade redistributes production activities to regions with varying emission intensities. This study finds that the convergence of emission intensities between the global South - North and changes in trade patterns have resulted in declining net emissions in trade in the past decade.

Carbon reduction technology pathways for existing buildings in eight cities
Here, the authors perform analysis of technology pathways for existing buildings using urban building energy models developed with cities, showing that shallow and deep retrofits along with onsite photovoltaic and grid decarbonization can help achieve carbon reduction targets.

Global urban expansion offsets climate-driven increases in terrestrial net primary productivity
Robust estimates of either urban expansion worldwide or the effects of such phenomenon on terrestrial net primary productivity (NPP) are lacking. Here the authors used the new dataset of global land use to show that the global urban areas expanded largely between 2000 and 2010, which in turn reduced terrestrial NPP globally.

Global potential of biospheric carbon management for climate mitigation
Carbon mitigation is considered an important and viable pathway towards climate stabilization, but competition for land is high. Here, Canadell and Schulze consider the sustainable implementation of a number of land-based biological carbon mitigation activities and assess the carbon savings achievable by 2050.

Conventional tree height–diameter relationships significantly overestimate aboveground carbon stocks in the Central Congo Basin
Accurate estimates of tropical forest carbon stocks are needed for policies to reduce emissions from loss of forests. By looking at a central area in the Congo Basin, Kearsleyet al.find that inconsistencies in height–diameter relationships across Central Africa cause overestimations between regions.
