SimaPro LCA Summit

To mark 35 years of SimaPro and PRé Sustainability, we held the first-ever SimaPro LCA Summit — two online sessions on November 25 and 26, 2025. The Summit offered a reflective journey through the past, present, and future of SimaPro (now part of One Click LCA), and gathered LCA experts, sustainability professionals, and curious newcomers. The recordings of both sessions are now available below.

Day 1 — 35 years of advancing LCA

On November 25, we opened with a look back at key milestones in SimaPro’s history and the evolution of life-cycle assessment. Mark Goedkoop (Founder of PRé) and Eric Mieras (Chief Innovation Officer at One Click LCA & Managing Director at PRé) shared four key learnings acquired on this 35-year journey.

The presentation was followed by a roundtable discussion. Online attendees heard from experts including:

  • Carmen Alvarado, Senior Sustainability Manager at Fuji Oil
  • Eric Mieras, Chief Innovation Officer at One Click LCA & Managing Director at PRé
  • Falko Parthey, Head of EHS of Siemens Energy
  • Henry King, former Director of Environmental science and technology at Unilever
  • Marisa Vieira, Director of Solutions at PRé
  • Mark Goedkoop, Founder of PRé

This first day offered both a celebration of progress and a reminder of how far the field has come — from early LCA tools to internationally recognized practice.

Day 2 — Bridging sustainability strategy and execution

On November 26, the SimaPro LCA Summit shifted focus to the future. As SimaPro has now become part of One Click LCA, we explored the new opportunities this creates for organizations using SimaPro and aiming to turn sustainability goals into measurable action.

A second roundtable discussed how scalable LCA can help close the gap between sustainability strategy and execution — emphasising how tools like SimaPro Synergy support teams embedding sustainability across operations.

Speakers included:

  • Eric Mieras, Chief Innovation Officer at One Click LCA & Managing Director at PRé
  • Llorenç Milà i Canals, Head of the Secretariat of UNEP’s Life Cycle Initiative
  • Mohammad Salikandi, Sustainability Manager at A.I.S.E
  • Panu Pasanen, CEO & Founder of One Click LCA
  • Sanne Dekker, Manager Public Affairs at FrieslandCampina

35 years of SimaPro

Did you know that the first version of SimaPro ran on four floppy disks, on MS-DOS with just 640 KB of memory – less than one smartphone photo today. Its database contained only a few impact categories: energy use, toxic emissions, acidification, and waste generation.
