Lise Laurin, CEO and Founder (Woman-owned Business)

Lise Laurin CEO and Founder of EarthShift and EarthShift Global.Lise is a pioneer in Sustainable Return on Investment (S-ROI) and Life Cycle Assessment (LCA). She founded EarthShift in 2000, adopting these methodologies to support North American industries’ early efforts at sustainability. Lise continues to develop and leverage EarthShift Global’s training, simplified 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 is currently the driving force behind the LCA Roadmap, working with the SETAC North America Life Cycle Assessment Advisory 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 within the International Standards Organization (ISO) Technical Advisory Groups for LCA and Ecolabeling. 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 for a range of clients. She also directs EarthShift Global’s software development and support and teaches advanced training courses in LCA, social impact assessment and S-ROI.

Valentina Prado PhD, Senior Sustainability Analyst

Valentina brings extensive expertise in developing decision analysis tools for life cycle assessments (LCA), and hands-on experience in the Sustainable Return on Investment (S-ROI) assessment methodologyValentina brings extensive expertise in developing decision-analysis tools for life cycle assessments (LCA), and hands-on experience in the Sustainable Return on Investment (S-ROI) assessment methodology. Her research focus has been in the incorporation of decision analysis to the interpretation stages of comparative LCAs, and tackles issues of normalization, weighting and uncertainty.

Prior to joining EarthShift Global, Valentina was an assistant professor at the Institute of Environmental Sciences (CML) at Leiden University in the Netherlands where she taught LCA theory and application in the Master’s program of Industrial Ecology. She also supervised MS students in their thesis work. In 2019, Valentina joined the management faculty of Universidad de los Andes in Bogota, Colombia, as a visiting professor.

She conducted several S-ROI workshops for EarthShift Global’s predecessor company, and has done groundbreaking work in decision support for LCA which we will continue to extend as part of EarthShift Global's suite of tools.

Valentina holds a BSc with honors in Civil Engineering from Jackson State University, and an MSc and PhD from Arizona State University in Life Cycle Assessment and Decision Analysis.

David Evers, Senior Sustainability Analyst

David brings extensive expertise in developing decision analysis tools for life cycle assessments (LCA)David’s work in life cycle assessment (LCA) and sustainability dates to 1988, when he began a two-decade tenure at the Battelle Memorial Institute . He led and participated in projects for a broad range of sectors (including product design and packaging, manufacturing, utilities, and defense) covering topics like pollution prevention/waste minimization, water and wastewater treatment, recycling and product takeback, and sustainability and LCA with particular emphasis on system modeling.

He subsequently spent six years with Hexion Inc., supporting the company’s Responsible Chemistry approach by conducting LCAs, overseeing all data compilation for Hexion’s sustainability reporting, and creating sustainability assessment tools for use by non-sustainability professionals.

Most of David’s recent projects have focused on improving product and process design by integrating environmental and cost information and incorporating lifecycle and sustainability concepts. This includes development of decision-support systems and business process modeling, as well as LCAs and integration of lifecycle concepts into systems design and engineering.

David draws on a background in civil, sanitary, hydraulic, and chemical engineering, and has also worked in environmental microbiology. He earned BS and MS degrees from The Ohio State University in Civil (Environmental) Engineering, specializing in water supply, treatment, and distribution, is accredited by the ACLCA as a Life Cycle Assessment Certified Professional, and has an extensive publication and presentation record.

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 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 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 publication. 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.
