World leaders adopted in 2015 a set of global goals to eradicate poverty, protect the planet and ensure prosperity for all as part of a new sustainable development agenda. The world is becoming increasingly centered on cities. Since 2007, more than half of the world's population has been living in cities, and that number is expected to rise to 60% by 2030.
Cities and metropolitan areas are the nerve centers of economic growth, contributing about 60% of global GDP. However, they also account for about 70% of global carbon emissions and more than 60% of resource use. It is therefore essential that research efforts are made in more sustainable cities, for this the lines of research that are requested in this Research Topic are those focused on these objectives, such as: sustainable transport, reduction of energy needs, and circular economy for energy recovery of waste.
Energy poverty is a key challenge facing people living in cities in all regions. It also risks increasing poverty and inequality by limiting access to lighting, cooling, heating, or clean cooking for the most at risk. The implementation of energy efficiency measures, programs to modernize households, reduce energy demand and modify tariffs by time slots to distribute energy consumption, are measures that are being successfully applied. Sustainable mobility in cities aims to reduce CO2 emissions but also to save energy and improve the quality of life of citizens. Some examples are the increase of public transport, the use of renewable energies, the use of bicycles and electric scooters. Within the circular economy, biomass for energy use can be a great example. Biomass is organic matter of plant or animal origin, found in large amounts in urban waste, which can be used as a renewable energy resource.
