The éco21 programme objectives

Energy savings constitute one of the key components of the energy transition. They contribute to the conservation of natural resources and the climate, and to the phasing out of nuclear power at a local and global level. Since 2007, the SIG-éco21 programme has been successfully supporting Geneva residents in reducing their energy consumption and their CO2 emissions.

Aligned with the objectives of the Confederation (Energy Strategy 2050) and of the Canton of Geneva (Société à 2000W), it aims to make Geneva the most efficient region in the world.

SIG can also develop partnerships with local firms or with Industrial Services in other Cantons in Switzerland to promote the éco21 programme solutions.

Good to know


SIG-éco21 is a partner of TopTen, the online platform that enables you to easily and quickly locate the most efficient products at the best price. Topten compares products in terms of energy efficiency, environmental impact and quality, while remaining neutral and independent.


SIG-eco21 and the State of Geneva are joining forces to encourage the energy transition with the GEnergie2050 shared platform to enable easy and straightforward access to various subsidies, solutions and advice. As a first step, you can find support for heating systems (via the éco21 Renewable Heat programme) and building envelopes on it.


Through to the end of 2019, the GEnergie 2050 platform has made an unprecedented budget of 35 million available in the form of subsidies to accelerate the energy transition across the Canton.
