Big cities, big footprints

As hubs of activity, they are a big source of carbon emissions. Urban areas account for 60-80 % of global energy use and around the same share of CO₂ emissions, so they have a large carbon footprint. But as well as being part of the problem, cities can also be part of the solution. Cities across the EU are changing for the better, thanks to the innovation and vision of local leaders who are helping reduce emissions and adapt to climate change impacts though smart planning and clever schemes.

Mayors on a mission

Cities across Europe have made a voluntary commitment to take measures to reduce greenhouse gas emissions and prepare for the impacts of climate change.

They have joined the Covenant of Mayors, a European Commission scheme to encourage cities to cut emissions and adapt to climate change. Cities are increasing energy efficiency and the use of renewable energy sources and sustainable transport, as well as 'climate-proofing' infrastructure, developing urban green areas and adapting civil protection, amongst other initiatives.

In 2016, the Global Covenant of Mayors for Climate and Energy was launched to accelerate climate action at local level all over the world.

Now over 11 000 cities from 142 countries and 6 continents are working together for the climate. Is your city – or the city closest to you – on board?

The energy consumption of buildings constructed nowadays is on average about one third of the energy consumption of buildings constructed before 2005.

Accessible cities

Car-free days are a great way of getting people to explore alternative ways of getting around town. This is one of the events that take place in many cities during European Mobility Week, a campaign supported by the European Commission which is organised every September.

More than 8 000 permanent measures, such as carpooling and bicycle-sharing schemes, have been introduced thanks to the campaign.

Cities cover around 2% of the Earth’s surface but are home to more than half the world’s population.

Preparing for extreme weather in Copenhagen

In July 2011, it rained in Copenhagen...
but this was no ordinary shower. Around 15 cm of rain fell in just 2 hours. The city’s drains could not cope with the volume of water and buildings and roads were soon flooded.

Two of Copenhagen’s major hospitals were threatened with closure because of flooding and power cuts. The event made the city’s leaders think about drawing up a plan to protect the city from future extreme weather events.

As a result, a 'Cloudburst Management Plan' was developed which not only helps manage rainwater better but is also improving the quality of city life. The scheme even includes new bicycle routes that also serve as storm-water channels.

Save energy, save money

More efficient buildings and appliances can save huge amounts of energy, emissions and money. A large amount of energy used by households in the EU goes on heating homes.

Triple-glazed windows, good insulation, and roofs covered with plants that help to keep buildings cool are just some of the ways to reduce the carbon footprint of our homes, schools and offices.

By the end of 2020, all new buildings in the EU will have to be nearly carbon-neutral.

European Green Capitals

The European Green Capital award is given to cities that are committed to becoming more sustainable. The aim is to reward cities that have been achieving high environmental standards in the long-term, to encourage cities to commit to ambitious goals and to motivate other cities by creating a space for cities to inspire each other to share ideas and experiences.
