Accelerating the Deployment of Absolute Zero Emissions Shipping
ZESTAs unites the innovators and technologies driving absolute zero in shipping — on vessels, in ports, and across the supply chain
Absolute Zero, No Compromise
We focus exclusively on technologies that eliminate emissions entirely — green hydrogen, electrification, wind propulsion, and battery systems.
Built for Deployment
Deployment needs more than a single solution.
Shipowners, tech providers, ports, and finance — working together to make it happen now.
Global Platform
Through ShipZERO workshops, IMO advocacy, and strategic partnerships, we drive real-world progress and amplify member impact worldwide.
Built for Absolute Zero
ZESTAs is a global industry association accelerating the deployment of Absolute Zero Emissions technologies in shipping — right now. Our members span the full maritime value chain, from shipowners and fuel providers to ports, power systems, and finance.
We convene cross-sector collaboration through the ShipZERO workshop series, contribute to regulatory development at the IMO, and support deployment ecosystems built on technologies that fully eliminate GHG emissions — not reduce them.
Founded in 2019, ZESTAs is focused, independent, and unapologetically practical. We’re not here to describe the transition. We’re here to deliver it.

Engage in technical input and high-level advocacy at the IMO — where decisions are made.
Global Recognition
Gain visibility as a trusted, technically grounded solution provider in Absolute Zero shipping.
Strategic Continuity
Stay connected through ShipZERO workshops, events, and long-term ecosystem-building efforts.
Our Members
We’ve Got the Power! Collaboration for Disruption
Held in Amsterdam in 2022, ShipZERO26.5 saw the industry create a plan to pull together resources and stakeholders to transition port infrastructure, shipping lanes, and ship design from concept to build, as well as the full spectrum of contractual relationships.
Charging to True Zero
Held in Glasgow during COP26, Ship ZERO26 brought together industry leaders to chart a course to Absolute Zero using real technologies already in play. The first output—a policy paper—was shared with COP26 delegates. The final deliverable, Charging to True Zero°, has been delivered to the IMO and shared with key stakeholders as a written report. All sessions were recorded.
When, Where, and How is Absolute Zero Shipping Possible Now?
Held in September 2023, ShipZERO28 tackled the urgent question: how can the shipping industry align with IPCC’s 1.5°C trajectory—now?
Three shipowners shared real-world challenges, sparking practical discussions on combining technologies and strategies to reach Absolute Zero. Strategic plans were shaped, laying the groundwork for future deployment.
Key outcomes were shared in a follow-up ShipZERO28 Online Webinar. All sessions were recorded.
