KPI Name Low-Carbon Emission Passenger Vehicles
KPI No. EC: I: T: 8A Type: Advanced Type: Sustainable

Definition / Percentage of low-carbon emission passenger vehicles
Description

Rationale / “Plug-in hybrids, sometimes called Plug-in Hybrid-Electric Vehicles (PHEVs),
Interpretation / are hybrids with high-capacity batteries that can be charged by plugging them into
Benchmarking an electrical outlet or charging station. They can store enough electricity to
significantly reduce their fuel use under typical driving conditions.” (US Department
of Energy)
“All-electric vehicles (EVs) run on electricity only. They are propelled by one or
more electric motors powered by rechargeable battery packs. EVs have several
advantages over conventional vehicles:
▪ Energy efficient: EVs convert about 59%–62% of the electrical energy from the
grid to power at the wheels. Conventional gasoline vehicles only convert about
17%–21% of the energy stored in gasoline to power at the wheels.*;
▪ Environmentally friendly: EVs emit no tailpipe pollutants, although the power
plant producing the electricity may emit them. Electricity from nuclear-, hydro-,
solar-, or wind-powered plants causes no air pollutants; and
▪ Performance benefits: Electric motors provide quiet, smooth operation and
stronger acceleration and require less maintenance than internal combustion
engines (ICEs).” (US Department of Energy)
Cities should count both PHEV and EV as low emission vehicles.
An improving trend and higher values are considered positive.

SDG Reference(s) SDG Target 11.2 By 2030, provide access to safe, affordable, accessible and
sustainable transport systems for all, improving road safety, notably by expanding
public transport, with special attention to the needs of those in vulnerable
situations, women, children, persons with disabilities and older persons.
