MarineFifty is an investment firm focused on marine sustainability, supported by a diverse and experienced team from shipping, energy, chemicals, sustainability, finance, and strategy. We are part of The Fifty Group, giving us access to deep technical expertise, investment infrastructure, and an active deal pipeline.
Our mission is to accelerate and underpin the shipping industry’s journey to net zero through targeted investments in technologies and solutions capable of achieving industry-scale impact.
Shipping accounts for nearly 3% of global emissions. Yet progress remains slow. Major cargo owners, financiers, and regulators are demanding credible action. Without meaningful investment and execution, the sector risks rising capital costs and reputational damage.
60–70% of emissions reductions in shipping must come from breakthrough tech, fuels, and infrastructure — all areas where MarineFifty invests. We provide capital, credibility, and collaboration to help innovations reach scale.
The shipping industry needs urgent and pragmatic decarbonization — but most capital is not configured to support it. MarineFifty’s deep sector alignment and flexible investment model allow us to address this challenge.
MarineFifty draws on the broader expertise of SkiesFifty, and other members of the Fifty Group, a sustainability-focused investment group spanning aviation, shipping, clean fuels, innovative technologies, carbon-offset, venture capital and structured finance.
If you are interested in discussing any aspect of our mission to fund the journey to carbon-neutral oceans, we want to hear from you.
