Lise Laurin
Lise Laurin
CEO and Founder

Lise is a pioneer in Life Cycle Assessment (LCA) and Sustainable Return on Investment (S-ROI). She founded EarthShift in 2000, adopting these methodologies to support industries’ efforts at advancing their sustainability. Lise continues to develop and leverage EarthShift Global’s training, LCA tools and S-ROI tools to build organizational capacity and drive large-scale change. Her unique skillset and knowledge base has put her in demand globally by companies, organizations and governments alike.

Lise initiated the LCA Roadmap, working with the joint ACLCA/SETAC Life Cycle Assessment Interest Group. She was a member of the UNEP SETAC Life Cycle Initiative team working on Organizational LCA (O-LCA) and advocates for a balanced, holistic approach to LCA as a board member with the American Center for Life Cycle Assessment. She is an ACLCA-accredited Life Cycle Assessment Certified Professional.

She continues to develop S-ROI, having broadened the scope from the original Total Cost Assessment methodology to include benefits and impacts to society, and in particular how a decision can be adapted to be a win-win-win solution for all stakeholders. Under Lise’s guidance, the technical team at EarthShift Global produces high-quality, high-value assessments and develops new LCA techniques to benefit EarthShift Global’s clients and the broader LCA community. She also directs EarthShift Global’s software development and support and teaches advanced training courses in LCA, social impact assessment, and S-ROI.

Lise received the 2017 Rita Schenck Lifetime Individual LCA Leadership Award at the LCA XVII ACLCA Conference. In her acceptance speech, Lise reminded everyone that there is still work to do, and challenged the audience to find positive cascading non-linear solutions to help with the world's problems.

Strategic Sustainability Roles on Corporate and Industry Advisory Boards

Lise is the Vice President of the Sustainability Conocente Network, a member of the board of directors for the ACLCA, a member of the joint ACLCA/SETAC Steering Committee for the LCA interest group, and an advisor to the AIChE Institute for Sustainability and Engineers for Sustainability. She holds a BS in Physics from Yale University.

    Tom Whidden PdD
    Tom Whidden PhD
    Chemistry Fellow

    Tom’s extensive experience in many areas of industrial process chemistry began with training as an inorganic fluorine chemist. At Dow Chemical, he supported a world-scale process plant and researched polymer catalysis and properties; he later moved to Advanced Semiconductor Materials in Phoenix, AZ, where he developed variations on chemical processes for semiconductor production.

    In the early 2000s, the issue of anthropogenic climate change captured his attention and he spent the next dozen years as director of research for Atlantic Hydrogen Inc., leading the development of sustainable processes for hydrogen production (and simultaneously developing expertise in LCA methodologies for retrospective process analysis and anticipatory process screening).

    Tom’s academic work includes early participation in nanotech boom as a member of the Center for Solid State Electronics Research at Arizona State University, Tempe, AZ, where he investigated nanolithographic patterning science for quantum device fabrication. He later organized and led a joint industry/academia research team with the University of New Brunswick in Fredericton, NB, Canada, with a focus on in-situ chemical sensing methodologies and feedback control protocols for use in semiconductor chemical processes.

    This background in industrial process development, advanced academic research, and practical process implementation and optimization gives Tom a unique perspective for assisting EarthShift Global’s clients. His strengths will be especially useful in understanding process sustainability issues in existing and proposed industrial chemical processes, including the identification of solid proxy data for chemicals not yet in databases.

    Dr. Whidden holds a PhD in chemistry and has authored or co-authored over 60 peer-reviewed publications. He served for five years on Canada’s National Sciences and Engineering Research Council’s Strategic Projects Grant Committee and is currently an adjunct professor in the Chemical Engineering Department and an Honorary Research Associate in the Chemistry Department at the University of New Brunswick.
