About Us

Climate Navigator is on a mission to combat climate change by working together find pathways to success through bold climate action.  This mission is our foundation and underpins everything we do.

  • We are a purpose-driven consultancy business.

  • We are a social enterprise, committed to putting our money where our mouth, including by allocating a significant share of our profit to support climate action.

  • We aim to make our services accessible and affordable for any organisation committed to bold climate action.

  • We aim to be climate positive by offsetting at least 120% of our emissions through ecologically-beneficial forests.

  • We believe that collaboration is critical, and seek to create an ecosystem of organisations working together to enable bold climate action.

If you are on a similar mission, say hello and let's explore how we might work together to grow our impact.


Meet Our Team

Sam Elder

Founder & Director


Sam is a systems thinker who thrives when working with others to address the major challenges and opportunities we face as a society.  She started out in the 1990s working on some of the world's highest-risk space programmes, including an early mission to measure sea surface temperature and so detect climate change. 


Since moving to NZ in 2005 her eclectic career has included:

  • Coordinating NZ's largest Outcomes Based Investment science research programme at Plant & Food Research.

  • Creating industry-leading insight and analytics capability as the Retail Insight Manager at Meridian Energy.

  • Building capacity in social enterprise, innovation and impact as Southern Director of the Akina Foundation.

  • Managing the Hazards, Risk & Resilience and Transport & Urban Development portfolios as a Senior Strategy Manager at the Canterbury Regional Council, including the development of a first of its kind 'Climate Change Integration' programme and membership of the Leadership Group for the Southshore & South New Brighton Regeneration (Adaptation) Project.

Along the way Sam has gained a BEng (Hons) in Mechanical Engineering; qualified as a UK Chartered Engineer and a Project Management Professional; and gained an MSc in Architecture (Advanced Environmental and Energy Studies) and GARP's Sustainability & Climate Risk (SCR) certification.

In 2020 she chose to focus in on society's ultimate complex challenge - the urgent, must-win fight to combat climate change, and so Climate Navigator was born.

Rich Profile Pic.jpg

Rich’s core talent lies in his ability to take complex matters and communicate them in a manner that is engaging and creative, while remaining faithful to the content.  With some 30 years’ experience in C-suite roles in both private and public sectors, Rich is confident to challenge the status quo in a respectful and constructive manner, to declutter complex narrative, and create a compelling ‘big picture’ story to enable a clear call to action.  


Rich completed a master’s degree in Science (Engineering Geology) from Canterbury  University in 1991 and has spent most of his career as a consultant scientist specialising in water, energy, and communications.  Rich’s career highlights include creating and leading a large water resources team at a multinational consultancy, consenting of ten renewable energy projects for Meridian Energy, and running business change initiatives at Meridian.


Rich is also the owner of Threesides Limited, a technical communications company that has clear synergies with Climate Navigator.  Threesides’  ethos reflects Rich’s personal values, specifically that trust underpins everything we do with our people and clients.


Rich jumped at the chance to join Climate Navigator as a Director from the outset as the importance of succeeding is simply too important.  And to be fair, the company founder in full flight does present an extraordinary case for bold change.

As a systems scientist, Chrys is interested in how we work with the uncertainty inherent in a system with myriad unexpected connections and across our political, cultural and professional differences to achieve the results we want.  She is passionate about the “why” and the “how” of things, because, while human beings seem pretty good at coming up with what to do, they often miss the “why” and the “how” of doing that. 

Chrys spent eight years at Landcare Research working with people in a range of contexts (community groups, local government, central government, business) on everything from catchment management, biodiversity and pest management, to climate change.  The work used adaptive management techniques and an in-depth understanding of human behaviour and behaviour change principles to help communities address their issues, by integrating science knowledge with knowledge from their own mixed contexts. 

Since leaving Manaaki Whenua at the end of 2008, she has worked as an independent contractor in science communication, social research and evaluation, and community development where she has put a lot of her research learnings into practice to bring about change. 


Sea Rotmann


Dr. Sea Rotmann has a PhD in marine ecology and environmental studies, but has focused on sustainability implementation in policy, practice, and research, since 2005. In late 2011, she started

her own consultancy called SEA - Sustainable Energy Advice Ltd, focusing on turning behaviour change theory into (global) best practice. She ran Task 24, the first global research collaboration

on behaviour change in demand-side management (DSM) for the DSM Technology Collaboration Programme (TCP) by the International Energy Agency (IEA) from 2012 to 2018. She has been researching hard-to-reach energy users in the residential and commercial sectors for the IEA’s Users TCP since 2019.

She has researched and utilised storytelling and narratives in her work since 2010 and has developed a BEST (Behaviour, Energy and Sustainability Training) Programme for Energy Managers with her research partners at the Californian See Change Institute. She’s also been a 3-time Green Party candidate, Co-Chair of the Guardians of the Bays (fighting the Wellington Airport runway extension) and coordinated XRANZ’s 2019 week of action.

Sea and her fiancé Karl have recently bought 35ha of land in paradise in Mohua / Golden Bay. They’re planning to turn it into an eco-community, with wetland and forest restoration projects and a regenerative farm.
