energy efficiency

As a key factor in the fight against climate change and a reliable means of reducing energy costs for citizens and cities, energy efficiency is a priority for our members.

Cities are continuously working towards improved energy efficiency by:

  • refurbishing public buildings

  • incentivising renovation of private buildings where possible

  • improving public transport and overall urban transport management

  • investing in more energy efficient heating and cooling, such as through district heating and cooling, and seasonal thermal storage

  • increasing energy efficiency of public lighting, for instance through the installation of LED lighting

  • supporting, developing and installing renewable energy within city boundaries, such as energy from waste, biomass, solar, ground/air/lake/sea source and more

Energy efficiency is also one of the priorities of the Europe 2020 strategy for smart, sustainable and inclusive growth and for the transition to a resource efficient economy.

Better efficiency helps ensure security of energy supply, and reduce emissions of greenhouse gases and other pollutants. By 2020, the EU wants to reduce primary energy consumption by 20%.

Cities recognise the central role they play in achieving this goal. On the one hand, 80% of energy in Europe is used in cities. On the other hand, a well-managed urban concentration reduces transport distances for people, goods and energy, and provides potential to increase the energy efficiency of heating and cooling.

We support our members in achieving their energy efficiency goals by providing a platform for cities to exchange best practice, input into EU energy efficiency policy and play a key role in a number of European initiatives, such as the Covenant of Mayors, our CASCADE and NiCE projects, EPOMM-PLUS and CIVITAS.

Our Declaration on Climate Change outlines cities’ commitment to reducing emissions, including through energy efficiency. Driven by our members’ ambition, we also launched our Green Digital Charter, which provides a framework for cities to use ICT as a main driver to improve energy efficiency.

Dublin, think energy

Think Energy encourages energy efficiency by working on two linked fronts: To provide information so people can make intelligent choices about energy use, and to change the culture around energy saving. This case study deals with a one-year campaign in Dublin’s civic offices and a permanent measure of equipping public libraries with ‘energy savings kits.'

Cities leading the way on climate action

Cities are climate leaders. 64% of EUROCITIES members have already committed to reach carbon neutrality by 2050. Among them, 12 cities have even committed to reach neutrality before 2040. And climate mitigation is only one side of the coin; 87.5% of our cities have adopted climate adaptation strategies to adapt to the impact of climate change and to protect their citizens.

“We are the Pragma Party”

Why would the European Commission give cities a seat at the table? Our secretary general, Anna Lisa Boni, speaks to goal 12 of our 100 days campaign.
