Europe's largest city network for climate action, specializing in municipal energy financing, building renovation, and net-zero urban transitions across 1,800+ member cities.
Climate Alliance is Europe's largest city network dedicated to climate action, connecting over 1,800 municipalities. They help local governments design and implement sustainable energy plans, financing schemes for building renovation, and citizen engagement strategies. Their practical work focuses on enabling cities to move from climate commitments to concrete investment — developing one-stop-shops for retrofits, innovative financing models like revolving funds and project bundling, and capacity building for energy efficiency at the municipal level. They serve as a bridge between EU policy frameworks (like the Covenant of Mayors) and on-the-ground implementation in cities across Europe.
CITYnvest (their only coordinated project) focused on innovative financing for energy efficiency; FALCO, EUCF, PadovaFIT Expanded, and EUROPA all address investment concepts, revolving funds, and project bundling for cities.
outPHit (EnerPHit, passive house), BUILD UPON2 (decarbonising building stock), EUROPA (deep renovation with performance guarantee), crossCert (energy certificates), and PadovaFIT Expanded all target building energy performance.
CEESEU focuses on SECAPs and multi-level governance for Energy Union goals; EUCF builds city capacity for investment concepts; FALCO and CITYnvest address Covenant of Mayors implementation.
CONNECTING Nature applied nature-based solutions in front-runner cities; INTERLACE focused on urban ecosystem restoration across EU and Latin America.
ENPOR addressed energy poverty in the private rented sector; SCORE promoted consumer co-ownership in renewables; WHY modeled household energy behaviour and social assessment.
NetZeroCities (2021-2025) accelerates cities toward net zero by 2030 through systems change and citizen engagement; this represents the latest direction alongside crossCert.
In their early H2020 period (2015–2018), Climate Alliance focused on foundational energy efficiency topics: smart meter data analysis, water-environment challenges, participatory governance models, and initial work on innovative financing for cities. From 2019 onward, their portfolio shifted decisively toward deep building renovation (EnerPHit, passive house, prefabrication, certification schemes), green public procurement, energy poverty, and ambitious net-zero city targets. The trajectory shows a clear move from awareness and capacity building toward implementation-ready tools — financing mechanisms, quality assurance for retrofits, and performance guarantees.
Climate Alliance is moving toward implementation-scale building decarbonisation and net-zero urban transitions, making them an increasingly valuable partner for projects that need to demonstrate real energy savings in cities.
Climate Alliance operates almost exclusively as a consortium partner (17 of 18 projects), with only one coordination role (CITYnvest). This reflects their function as a network multiplier: they bring access to hundreds of member cities across Europe rather than leading technical research. With 237 unique partners across 39 countries, they are a highly connected hub — making them an excellent entry point for projects that need municipal engagement, pilot city recruitment, or dissemination to local governments at scale.
With 237 unique consortium partners across 39 countries, Climate Alliance has one of the broadest municipal networks in H2020. Their reach spans all of Europe with particular strength in Western and Central European cities, plus connections to Latin America through INTERLACE.
Climate Alliance's core advantage is scale of municipal access — as a network of 1,800+ cities, they can recruit pilot municipalities, disseminate results to local governments, and validate solutions in real urban contexts faster than almost any other partner. Unlike research institutes that bring technical depth, or consultancies that bring methodology, Climate Alliance brings the cities themselves. For any consortium that needs to demonstrate impact at the local government level across multiple European countries, they are a near-irreplaceable partner.
