One Planet Port is an independent Dutch NGO (ANBI), based in Rotterdam. We combine scientific research with policy work and public communications, focused on transforming the Port of Rotterdam into a port that operates within planetary boundaries.
Our work is made possible by the support of a number of leading organisations. We receive funding from the Meliore Foundation, the ClimateWorks Foundation, the European Climate Foundation (ECF) and the Convergence Resilient Delta Initiative (RDi).
We are also part of PortCityFutures – a research consortium of Leiden University, Delft University of Technology, and Erasmus University Rotterdam – and participate in six working groups of the PACT, a COST (European Cooperation in Science and Technology) Action network supporting port cities in achieving an inclusive energy transition. We are members of Transport & Environment (T&E) and Seas At Risk, two leading European organisations working on mobility, climate, and ocean health.
Our Staff
Dr. Lucy Gilliam
Co-executive Director, STEM Scientist, Co-Founder
Dr. Lucy Gilliam is an environmental scientist and policy specialist with a BSc in biological sciences and a PhD in microbial ecology. She spent eight years shaping shipping policy at Brussels-based NGOs Transport & Environment (T&E) and Seas At Risk, contributing to EU and United Nations International Maritime Organization (IMO) regulations. Along the way, she became convinced that climate targets cannot be met by fuel substitution alone; systemic change is needed. That conviction brought her to Rotterdam: Ports determine which fuels are available, which ships can dock and how operations run, making them one of the most powerful levers for transforming global trade. At One Planet Port, she applies that expertise to science-based policy and campaigns focused on shipping, ocean governance and ecosystem-based management – and as co-founder of eXXpedition, she takes that mission literally out to sea.
Tanner Tuttle, MSc
Co-executive Director & Environmental Psychologist
Tanner Tuttle is an environmental psychologist and Co-Executive Director of One Planet Port. His career began in project management, first in IT, then in television and film in Los Angeles, working for MTV, Paramount Pictures and The Walt Disney Company where he learned to turn complex ideas into executable plans and stories that move people. A volunteer experience with war refugees on the Greek island of Chios changed his direction: it made abstract global problems personal and urgent. He went on to study psychology at Erasmus University and environmental psychology in Groningen, in search of what he calls “high-value societal problems.” Books like Donut Economics and Prosperity Without Growth, combined with meeting Lucy Gilliam through a Erasmus University/TU Delft research project on ammonia as a shipping fuel, brought everything together. At OPP, he leads strategic planning and programme development, bringing his dual background in storytelling and systems thinking to bear on a just, ecologically grounded transition of the port of Rotterdam.
Maëlle Salzinger
Policy and Academic Liaison
Maëlle Salzinger is a researcher and policy analyst based at TU Delft and One Planet Port. She holds a master’s degree (Cum Laude) from Sciences Po Paris and spent four years as a Policy Analyst and gender focal point at ECDPM, the Centre for Africa-Europe Relations. At OPP, she connects academic networks to transformative advocacy and policy change, driven by the conviction that knowledge must accelerate action toward just, sustainable transitions. OPP’s collaborative and systemic approach, bringing together science, creativity and urgency around Rotterdam and its port is a natural fit for her. A long-time dancer and nature lover, she believes in the power of embodied experience to shift mindsets and foster learning.
Marten van Dijl
Media Liaison, Editor and Outreach
Marten van Dijl is a photographer, journalist, editor and writer, with a portfolio spanning Dutch news agency ANP, natural history museum Naturalis and academic publisher SpringerScience. With Greenpeace, he sailed the Pacific documenting the industrial harvesting of polymetallic nodules from the seabed on a campaign calling for a global moratorium on deep-sea mining. His reporting on the impact of oil spills on local communities in Nigeria won a Zilveren Camera, a Dutch photojournalism award. As one who has spent years birdwatching in the Rotterdam area, he knows the Maasvlakte from before large-scale development transformed it. A responsibility for the world around us runs through his work and brings him to One Planet Port, where he handles communications and media relations.
