Environmental Impact

The environmental footprint of maritime shipping is not a small one. Responsible for oil leaks and catastrophic spills, insidious underwater noise pollution, more air pollution than all of the world’s cars put together, it produces up to 4-5% of total global carbon emissions.

The construction of maritime infrastructures, including clearing coastlines and dredging shipping lanes, contributes to the destruction of precious coastal ecosystems and vast amounts of Blue Carbon.

On a global scale, these issues are treacherous. In smaller, poorer regions of the world, such environmental impacts are significantly more concentrated.

Making the situation worse, it is precisely those marginalized communities that are most likely to depend tightly on their environments, via subsistence fishing, the buffering capacity of coastal wetlands against storms, etc.

We want to help turn these damaging realities around, not by trying to eliminate what already exists, but by providing a new model for 100% clean small-shipping and an alternative for vulnerable communities that depend most on their local environments.

Greenheart ships are designed to…

Run entirely on renewable energy

Our ancestors moved people and cargo around the world without fossil fuels. The energy they used – the winds and the currents – are still out there, free and ever-present, waiting to be taken advantage of as the forces that drove ships to fossil fuel make less and less sense.

Be 100% CARBON FREE in operations

In a world poised to be thrown into chaos by climate change, we can afford nothing less. The seas offer a unique opportunity to achieve climate friendly transport, starting as soon as today.

Produce surplus energy onboard

Not only do Greenheart ships not require burning fossil fuels, instead drawing on the power of the winds and currents to move, they actually capture and store surplus energy from the sun. This stored energy can be used for anything, from powering navigation equipment to providing a village with electricity in an emergency. As net energy producers, Greenheart ships are one of the only examples of truly regenerative transport in the world.

Emit ZERO pollution into land or sea

No release of toxic fumes. No leaking fuel or oil. No deep rumbling of engines to disrupt communication and health in marine life. Our presence on the seas need not be a damaging one.

Eliminate the need for extra port infrastructure

No more Blue Carbon from dredging extensive shipping lanes. No more paving over critical sections of coastal wetlands to build large port facilities. No more devil’s bargain between protecting the environment and economic development.

Provide an alternative to the heavy footprints of land transportation infrastructure

Historically, coastal cities were connected by ships, not trucks. Is a developing region truly better served by billion dollar highway projects that pave through forests and displace villages? Greenheart ships provide a lightweight, low-footprint, maritime solution that can accomplish the same goal of connecting population centers, for less money and less social and environmental pain.

Provide a much-needed affordable choice for fisheries monitoring (and ocean science)

Marine Protected Areas are a widely agreed upon necessity to mitigate overfishing and prevent key ocean resources from depleting. However, even after creation they are too often ineffective because the cost of monitoring and enforcement is beyond local budgets. Modern, versatile vessels that cost near nothing to keep in the water and that can stay out as long as they need, have the potential to revolutionize MPA enforcement and contribute to keeping our fisheries healthy.
