How do environmental technologies, CleanTech innovations and sustainable business models become internationally successful? There is a great demand for environmental and climate protection solutions worldwide, but how do foreign markets work and what needs to be considered? During my professional career, I have been able to look at these questions from different angles, as a project manager for a utility and a solar company, as a management consultant and now as project manager for internationalisation at the Landesagentur Umwelttechnik BW.
