Who are we?

ERF – Energia i Sostenibilitat S.L.U. is an independent energy, environmental and sustainability consultancy with more than 25 years of experience in the national and international markets prepared to lead companies and institutions to their transformation to sustainability.

Founded in 1994 by the socioecologist Ramon Folch, ERF is staffed by a multidisciplinary team of professionals (engineers, biologists, environmentalists, architects, communication experts...) who with techno-scientific rigour and a focus on feasible solutions, works alongside companies and institutions, advising them in their transformation to sustainability.

In 2023, ERF joins forces with ARCbcn engineering, specialized in complex installations and innovation projects, with the aim of building together a solid business project whose purpose is to advance towards the sustainability of our society.

The fact-based transition to sustainability

ERF successfully resolves complex projects through a combination of the company’s three specialist areas: consulting in the fields of the environment, regional development and urban planning; energy efficiency engineering; and sustainability and climate strategies in the design of plans, programmes and projects. Such projects always take into account the appropriate scale (regional, urban, neighbourhood, building or production sector) and the socio-political, economic and socio-environmental conditions in which strategies are to be implemented.
