Who We Are

GreenMatters is a consultancy specialised in thematic studies, policy advice for regional and local agencies, event moderation and marketing of green products. We work at European and international level advising public clients on green policy matters and supporting companies with innovative green ideas. We have over 20 years of experience in regional policy, the energy transition and the circular economy. GreenMatters can feature an outstanding set of references. 

Our mission is to make an active contribution to raising the share of renewables, to improving energy efficiency and to transforming the traditional linear economy (make-use-dispose) to a circular economy that keeps resources in use for as long as possible. Whether we work for small companies or big institutions, moderate workshops or major conferences, we are determined to deliver high-quality, tailor-made services and to see happy clients coming back for more.

GreenMatters is offering policy and business studies on the energy transition, energy efficiency, circular economy, waste management and climate change at European, national and regional level.


We advised INTERREG IVC, Interreg CENTRAL EUROPE and the European Commission on the SME Instrument and are making high-level expert presentations on the latest trends & developments in green matters. Since February 2018, we are acting as Low-Carbon Economy expert for the Policy Learning Platform of Interreg Europe.


GreenMatters is always looking for new, exciting products that are made to last and close the loop towards a circular economy. We are interested in innovative applications of renewables, in repurposing and recycling materials that were destined for disposal or incineration. GreenMatters supports companies in finding new, international markets and in promoting their products.


We have a long track-record in moderating workshops and conferences and in organizing World Café sessions around green matters. We are highly experienced in ensuring high-quality debates and a lively exchange of views and arguments.
