We are an independent energy, environment and sustainability consultancy with over 25 years of experience in the national and international market. We help and support companies and institutions in their adaption to sustainability. We make the sustainability transition possible.

We make the sustainability transition possible

We combine three areas of experience: environmental consulting; energy efficiency consulting; and sustainability and climate strategies planning.

We work on the definition of strategies, plans, programmes and projects, always on the basis of the appropriate scale (territorial, urban, neighbourhood, building or productive sector) and the socio-political, economic and socio-environmental conditions in which it is developed.


The beginning

Ramon Folch, PhD in biology and sociologist, founded Estudi Ramon Folch as an independent environmental and sustainability consultancy with the aim of helping and accompanying companies and institutions on their way to the sustainable transformation.

Ivan Capdevila, ERF director

With a cross-disciplinary education in engineering, the environment and humanities added to an extensive professional career within the consultancy sector, he became a partner and Director of ERF, since 2002, has broadened his experience through his role as Technical Director. He also works on management and business development.

WATTEGA is the product of the merger between ARCbcn and ERF

ERF merged with the engineering firm ARCbcn, which specialised in complex installations and innovation projects, and together they form WATTEGA, a solid business project whose purpose is to accelerate the progress toward sustainability in companies and institutions.
