New Zealand Nominates 6 Climate Solutions for Earthshot Prize

New Zealand is punching above its weight in the fight against climate change, and the world is taking notice.

Victoria University of Wellington just announced its six nominees for the 2026 Earthshot Prize, a prestigious global award that funds the most promising environmental solutions. The lineup showcases what happens when Kiwi ingenuity meets urgent planetary needs.

Among the nominees is Critical, a Māori-led company that transforms hard-to-recycle plastic into carbon-neutral building materials called Cleanstone. They're developing compact microfactories that communities worldwide could use to turn local waste into jobs and valuable products.

KiwiEconet took a different approach to the plastic problem. They invented bale wrap made from natural jute fiber that's completely biodegradable and even edible for livestock, replacing the petroleum-based plastic that farmers typically use for hay and silage.

Mushroom Material offers another alternative to plastic with packaging made from mycelium pellets. The innovation works with existing manufacturing equipment, making it easy for companies to switch without overhauling their entire operation.

The ocean cleanup efforts are equally impressive. Sea Cleaners operates specialized vessels that intercept plastic pollution before it disperses beyond recovery, removing millions of liters of waste from waterways annually. They're now expanding into the Pacific to build an island-led cleanup network.

Mountains to Sea Wellington Trust is restoring disappearing kelp forests in Wellington Harbour through their Love Rimurimu project. They combine science, community action, and Indigenous partnership while sharing their knowledge freely with others.

AgriZeroNZ rounds out the nominees by helping farmers reduce emissions without sacrificing profits. This public-private partnership invests in tools that work for pasture-based farms and can scale globally.

The Ripple Effect

These six projects share something beyond environmental impact. They're all affordable and immediately scalable, designed to work in the real world right now rather than someday in the future.

Andrew Wilks, Director of Sustainability at Victoria University, says every nominated solution has the power to change the world. As one of only 361 official nominators globally, the university chose projects that prove human ingenuity can drive collective action.

The nominees also represent New Zealand's best cultural traits: the famous Number 8 wire resourcefulness and the community spirit of a proper working bee. They show that meaningful climate solutions don't require massive infrastructure or impossible budgets.

Several nominees came from the Sustainable Business Network's Next List, proving that practical innovation is already emerging across New Zealand. These aren't distant concepts but working solutions solving real problems today.

Whether it's keeping plastic out of oceans, restoring marine ecosystems, or helping farmers work sustainably, these Kiwi innovations offer blueprints that communities worldwide can adapt and adopt.
