The reduction of CO2 in the cities gain traction with measurable projects and ambitious local policies. Zaragoza already quantifies the effect of its public charging network for electric vehicles, while Alcoy strengthens its climate roadmap to accelerate the transition.
In the Aragonese capital, the municipal charging network has already avoided almost 668 tons of CO2 through 149 points in 37 locations, and in parallel, the Alicante municipality outlines specific objectives: -55% emissions by 2030, -36% energy consumption in five years and at least 40% renewable energy in that period.
Zaragoza: How municipal charging is cutting emissions
The municipal stations of Zaragoza add up 149 charging points Distributed in 37 sites, managed by Endesa X Way (103 points in 26 locations) and Tinder (46 in 11). The Mobility area highlights that public infrastructure facilitates the electrification both urban and private transport.
The Mobility Service study estimates the energy supplied at 747.963 kWh (data as of 28/07/2025). With an average efficiency of 15 kWh / 100 km, this consumption is equivalent to approximately 4.986.420 km electric vehicle tours.
If that distance had been covered with diesel passenger cars, with an estimated consumption of 5 l / 100 km, some would be necessary 249.321 liters diesel. Thanks to electric charging in the city, that fuel has not been used.
In emissions, and using a factor of 2,68 kg of CO2 per liter of diesel, the equivalence results in some 668,2 tonnes of carbon dioxide emissions avoided. The electricity used in these chargers is 100% certified renewable, so the indirect emissions associated with its generation are considered practically zero.
For comparative purposes, if the average of the electrical system were applied (approx. 0,283 kg CO2/kWh), those 747.963 kWh would generate some 211,7 tonnes of CO2. Renewable energy eliminates this impact, consolidating savings compared to the use of fossil fuels.
The environmental equivalence of savings has also been translated into trees: in 1,5 years in the Making, would be needed around 20.248 copies to absorb the same amount of CO2, considering an average of 22 kg per tree and year.
- Energy supplied: 747.963 kWh (as of 28/07/2025)
- Equivalent distance: ~4,99 million km at 15 kWh/100 km
- Diesel avoided: ~249.321 liters (at 5 l/100 km)
- CO2 avoided: ~668,2 t; with medium electric mix, ~211,7 t
The Ministry of Environment and Mobility highlights that the municipal network, complementary to public transport (buses, trams and public bicycles), places Zaragoza among the large cities that are accelerating the electromobility with service and access criteria for residents and visitors.
Alcoy: objectives and measures to reduce CO2 emissions
City Council Alcoy has approved your Action Plan for Climate and Sustainable Energy (PACES), with clear goals: cutting emissions by 55% by 2030, reduce energy consumption by 36% in the next five years and achieve at least one 40% of energy from renewable sources.
In mobility, the council plans to strengthen the Low Emission Zones and expand pedestrian areas, common measures in historic centers where the dispersion of pollutants is more difficult. The goal is calm traffic, enable park-and-ride parking and improve accessibility without increasing the CO2 footprint.
The urban bus service is updated with environmental criteria: a fleet of 12 vehicles with 3 electric (there are already two in service), 3 hybrids, 5 diesels with ECO label y 1 minibusThe tender document incorporates the PACES parameters to guide the renewal towards low emissions.
For sustainable private mobility, work is being done on a new ordinance that regulates the use of electric chargers and intermodality with bicycles and scooters is promoted: smart parking, consolidation of the bicycle network and safe parking solutions on public streets.
Priority is also given to urban renaturalization: reconnect the town with the surrounding natural spaces, replant trees, remove invasive flora and create climate shelters that alleviate heat waves. These are actions that improve air quality and thermal comfort.
In the energy chapter, the municipality installs photovoltaic panels in public buildings and parking lots, and applies incentives such as IBI and ICIO bonuses for those who improve their self-consumption. In parallel, it advances in efficiency through carpentry and air conditioning renovations in municipal buildings.
Awareness is consolidated as a lever for change: a unified contract is put out to tender school environmental education (until 42.000 Euros to four years) to integrate workshops, nature outings and information campaigns, with special focus on habits that reduce CO2 long term.
Data from Zaragoza and Alcoy show how combining charging infrastructure, cleaner public transport, usage regulations and efficiency actions can tangibly and measurably reduce emissions. CO2, moving towards more ambitious climate goals, in line with the urgency of the climate crisis.
