Cities are playing the most important and widespread role in CO2 emissions globally and so that they constitute 75% of global CO2 emissions. This means cities are among the major energy consumer and at least the biggest emitter. When that’s said, it is interesting to point out that urban transport represented around 40% of the energy consumption in the transport sector in 2015. According to REN21’s report, this contributed to an estimated 37% of transport-related CO2 emissions (REN21 Renewables in Cities 2019). Thus, urban transport (air, rail, and road) is the backbone of energy consumption as well as CO2 emissions.
In reality, there is a shortage of authentic field data about the “share of renewable energy” in the energy market of cities. This is while cities are the biggest buyers and investors in renewable technologies in the power, heating and cooling, and transport sectors. We only know that electricity accounts for around 17% of global energy demand and renewable electricity supplies more than 26% of global electricity production (REN21’s report, Global Status Report). But we do not know in detail how much is the share of renewable electricity in urban transportation systems such as public transportation.
