From 1990, my company PRé developed the SimaPro LCA software in 1990 and developed methods like the Eco-indicator 95 and 99, followed by ReCiPe 2008; which are all well known.
In the 20 years that followed the LCA field was a nice niche market. We are moving from ad hoc LCA studies into a place where sustainability becomes part of the core strategies of companies, as a basis for companies to differentiate their products and to create value. 
Specialties: Bridge building, creating coalitions that help creating a better world. 
Pioneering science based but very pragmatic tools and methodologies
