CONCERTO is a European Commission initiative within the European Research Framework Programme (FP6 and FP7) which aims to demonstrate that the optimisation of the building sector of whole communities is more efficient and cheaper than optimisation of each building individually.



Developing our cities into intelligent and sustainable environments is one of the biggest challenges of our times. More than half of the world`s population lives in cities – a share that is expected to rise to 70 % by 2050. Already now, cities produce 70 % of all CO2 emissions. Cities are therefore faced with the challenge of ensuring their inhabitants` quality of life whilst moving away from fossil fuels towards more renewable energy sources and to more efficient and smarter energy systems. Smarter energy systems play a key role in meeting the EU’s energy policy targets for 2020 – consuming 20 % less energy, increasing the share of renewable energy to 20 %, reducing greenhouse gas emissions by 20 %. Meeting these targets will set up the EU for its long-term objective of reducing greenhouse gas emissions to at least 80 % below the 1990 levels by 2050, as set by the European Council.


The EU initiative of DG Energy has co-funded 58 communities in 22 projects in 23 countries and started in 2005.

CONCERTO demonstrates realised examples of:

•    innovative technologies ready to be applied
•    use of renewable energies sources for cities
•    energy efficiency measures
•    sustainable building and district development
•    economic assessments
•    affordable energy
•    energy transparency for citizens

The CONCERTO initiative is proving that cities and communities can, given the right planning, be transformed into pioneers in the world of energy efficiency and sustainability.



The detailed evaluation of 58 pilot cities and communities in 23 countries in the EU CONCERTO initiative impressively documents how innovative thinking on a larger scale can bring not just individual buildings, but entire communities to the level of the latest technological advancements in low-carbon energy systems. Thanks to their size and ambition, these projects have played a pivotal role in mainstreaming energy efficiency and renewable energy technologies in a number of Member States.

These pilot cities have shown that innovative technologies are available and ready to be used. They have proven that the built environment can cut its CO2 emissions by up to 80 % already now and that renewable energy sources can well be integrated into the urban environment. Building on these experiences, several of the CONCERTO cities are now broadening their scope to tackle smart energy, sustainable mobility and ICT as enabling technology in an integrated way under the European Union’s Smart Cities and Communities European Innovation Partnership, launched in July 2012.
