| Open AccessSustainability of global Golden Inland Waterways
The exploitation of rivers has been at the detriment of river ecosystems. Here the authors propose a concept of Golden Inland Waterways (GIWs) to represent large waterways and find that the exploitation ratio threshold around the turning point for most GIWs appear to be less than 80%, subject to ecological constraints.

| Open AccessSaving less in China facilitates global CO2 mitigation
The partial effects of saving rate changes on CO2 emissions remain unclear. Here the authors found that the increase in saving rates of China has led to increments of global industrial CO2 emissions by 189 million tonnes (Mt) during 2007-2012, while global CO2 emissions would be reduced by 186 Mt if the saving rates of China decreased by 15 percentage points.

| Open AccessEnergy transformation cost for the Japanese mid-century strategy
Computable General Equilibrium models can hardly decouple economic growth and energy consumption while energy system models can hardly predict macroeconomic implications of energy system changes. Here the authors investigated the macroeconomic implications of consistently dealing with energy systems and the stability of further power generation and show that GDP losses were significantly lower than those in the conventional economic model by more than 50% in 2050, while industry and service sector energy consumption are the main factors causing these differences.

| Open AccessImpacts of air pollutants from rural Chinese households under the rapid residential energy transition
Residential solid fuel use constitutes a large amount of air pollution but has been gradually replaced by other cleaner energy during the past three decades. Here the authors investigated the contribution of rural residential sector to ambient PM2.5 pollution and the resulting climate forcing and health impacts, and find that the remaining large quantities of solid fuels used in rural households are still a major contributor to ambient air pollution despite of decrease in its pollutant emissions and relative contribution to PM2.5 due to the clean energy transition.
