Our History

Standing up for Future Generations

We started Southern Ocean Carbon in 2020 for a couple of reasons: One was a desire to make our sister company ADEC Kedge carbon neutral. On close investigation, the options available at the time didn’t make us confident that we were actually going to make a tangible, positive difference to our planet. Then there were our children. They were asking us what we were going to do to rectify some of the harmful behaviours of past generations, how were we making sure that we were going to leave things better than we had found them? – something we had always encouraged our children to do when they were at school.

Adam had been listening to the radio one day: a segment on seaweed and its many types and properties. Tim Flannery published his book ‘Sunlight and Seaweed’, and that’s how we became aware of the many benefits of seaweed, and we were hooked.

Teaming up with Knowledgeable Partners

Through mutual friends, we became aware of the climate change power couple of Caroline and Tom Remenyi. Not only are they fabulous people, but they have skills and knowledge about things that we didn’t. Caroline is a seaweed growing expert and Tom a climatologist. The brains trust was formed, Caroline and Tom remain advisors to this day.

Backing Through World Class Research

We joined the Blue Economy Cooperative Research Centre (BECRC) in 2021 as one of 44 global partners. In collaboration with project leader Professor Craig Johnson and other experts in the field, we are working towards developing production systems for offshore kelp mariculture.

Learning, Growing and Evolving

What we thought we would do and what we have found ourselves doing has evolved over time, mostly in response to research. We are exploring options to grow seaweed globally because of the amazing properties it has, but our activities are not limited to this, so long as the “chain” remains clean – we are willing to explore and partner in a number of different projects, if they will restore some of the balance in biodiversity and achieve measurable positive outcomes.

Joining ADEC Innovations

In March 2023, Southern Ocean Carbon was acquired by ADEC Innovations, a global ESG, professional services and impact investment firm, a purpose-driven company aiming to accelerate the plans of Southern Ocean Carbon, especially the goal of being the leader in its field through its activities and consultancy.
