About this Research Topic
It is estimated by the United Nations that 75% of the global CO2 emissions are attributed to cities. Cities whose primary industry is services have reduced their local emissions, but it is suggested that their total emissions are growing continuously when embodied emissions from consumption are included. It is suggested that such cities outsourcing their production achieve their wealthy economy under the sacrifice of cities manufacturing the goods, contributing to the North-South problem internationally. Thus, cities must reduce their consumption or change their consumption behavior. Shifting to a greener consumption will not only help reduce emissions of the consuming cities but also decrease the emissions of the supplying cities. Recently, the consumption behavior of cities has changed due to the spread of COVID-19, with human mobility in cities decreasing due to the state of emergencies and lockdown restrictions, thus affecting the trades between cities.
The impact of cities’ consumption on greenhouse gas emissions, and how to conduct effective policy to mitigate such pressure, is becoming an essential issue. Although the COVID-19 pandemic is putting humanity in crisis, it also provides us the chance to understand how the decline in human mobility changes the economic activities of cities and how this is influencing their greenhouse gas emissions. Furthermore, mobility restrictions under the COVID-19 crisis increased the number of hours people stayed at home and changed levels of movement to business and commercial districts. We hope to gather studies investigating how these changes in mobility under the crisis affected the consumption and market behaviors, and how such changes have influenced the greenhouse gas emissions and other environmental pressures.
The Research Topic aims to publish articles, reviews, opinions, and case reports related to mitigating environmental pressure driven from consumption of cities associated with the following issues, but we welcome other relevant studies as well:
• Consumption of cities and climate change
• Policies for changing consumption of cities
• Sustainable, green, eco-friendly, and ethical consumption for cities
• Changes in greenhouse gas emissions related to the COVID-19
• Changes in markets (energy, agricultural, seafood, financial, metal, labor, and so on) related to the COVID-19
• Changes in human mobility in cities during the COVID-19
• Changes in trading among cities during the COVID-19
• Changes in wastes due to the COVID-19
• Socio-economic aspects of pandemic risk assessment and sustainable management
• Policy implications for smart cities
