Sustainable development is now a key growth industry and Luxembourg is committed to using its unique talents to find solutions to cut pollution and waste as well as creating wealth. Significant activity in green technologies is under way and the government’s "Luxembourg's Eco-Technology Action Plan” gives local green entrepreneurs financial and networking encouragement to research ideas in this potentially revolutionary field. There are already nearly 200 eco-companies in the country, working mainly in renewable energy, waste management, water and eco-construction supported by 28 public agencies and six research institutes.

There are numerous examples of how Luxembourg-based firms are globalising their innovations. The Société Electrique de l'Our (SEO) is boosting investment in hydro and wind power generation for both domestic use and export and Epuramat has developed a revolutionary waste-water processing system. A waste management concept has been elaborated in the United Arab Emirates and L.E.E.’s biogas plants are finding favour in European and Asian markets. China has been open to Rotarex’s compressed natural gas gas (CNG) conversion kits which slash pollution from old cars and motorbikes and Prefalux technology is keeping scientists safe and warm in Belgium's “Princess Elisabeth” Antarctic research centre.
Research facilities offer interesting posibilities, including the “Environment and Agro-biotechnologies” department of the Gabriel Lippmann public research institute. They specialise in digesters to assist research into areas as diverse as biogas, waste-water transformation and biopolymer production. Luxembourg is also proud of its national resource centre for environmental technologies (CRTE) which leads in the areas of life-cycle analysis, eco-design, eco-construction and renewable energies.
