An ocean remediation project, a predator-free blueprint, cleaner greenhouses, and a clean technology pioneer are the nominees put forward this year by Te Herenga Waka—Victoria University of Wellington to be considered for one of five £1,000,000 ($1.9m NZD) 2025 Earthshot Prizes.
The Earthshot Prize finds and grows the solutions that will repair our planet, addressing the challenge to regenerate the place we all call home in the next ten years. As a thought leader in sustainability, the University is the only official nominator based in New Zealand.
These remarkable sustainability solutions were selected by a panel for their potential for global impact, ability to be scaled or replicated, various environmental metrics, and solid organisational foundations.
The Earthshot Prize has a network of nominators all over the world who nominate game-changing innovations that will help repair the planet, awarding the best five solutions each year with £1 million to scale their work. The independent charity was founded by Prince William, and former Prime Minister, Dame Jacinda Ardern, is on the Board of Trustees.
The prizes are awarded to projects that highlight human ingenuity, drive change, and inspire collective action. The Earthshot Prize not only makes available the transformative financial resources of £5 million per year, it also has built a global, diverse, and hugely influential network of partnerships and collaborations involved with all levels of how the Prize works. All finalists get access to mentoring and support throughout the process.
In 2023, one of the University’s nominees, Sea Forest Ltd, was one of the fifteen finalists for The Earthshot Prize.
The University’s nominees this year are:
Predator Free Wellington
New Zealand is at the top of the global list for threatened or endangered native species resulting from predation by introduced mammals. Predator Free Wellington is creating the world’s first predator-free capital city where native wildlife and communities thrive. They are creating the urban blueprint for the Predator Free Aotearoa New Zealand 2050 goal. The Predator Free Wellington team are developing a scalable, replicable system to permanently eliminate target introduced predators (rats, possums, mustelids) from Wellington city’s 30,000 hectares. This transformational project is a world-first, being delivered in partnership with every single resident and providing a replicable system for urban environments everywhere.
Kaipara Moana Remediation
The Kaipara is the southern hemisphere’s largest harbour and a place of global importance. Once home to ancient forests, the 600,000-hectare catchment is now degraded by land clearance, with around 700,000 tonnes of sediment flowing into the harbour each year, and 90 percent of wetlands lost. Through novel collaborations, investment in people, and ‘end-to-end’ support, Kaipara Moana Remediation mobilises landowners, iwi/hapū, communities, industry, and government to protect 16,200 kilometres of riparian margins, regenerate wetlands, and re-forest eroding hillsides. Using next-generation digital tools to identify ‘hotspots’ in the landscape, Kaipara Moana Remediation supports landowners to offset on-farm emissions, restore ecosystem remnants, and improve resilience to cyclones and floods impacting local communities.
Hot Lime Labs
Seventy percent of commercial greenhouses use natural gas for heat and yield-boosting CO2. The CO2 byproduct from natural gas is critical for greenhouses as it boosts yield by around 20 percent. No other greenhouse heating solution delivers clean CO2, so transitioning from natural gas carries a huge penalty and a major abatement challenge. The Hot Lime Labs vision is to decarbonise half the world’s greenhouses by 2030, reducing fossil emissions by 120 megatons per year. Hot Lime extracts CO2 from forestry and crop waste, replacing fossil-based CO2. Their solution delivers renewable CO2, boosting customer yields and enabling greenhouses to transition to renewable heating and decarbonise their operations.
Mint Innovation
As global mineral reserves deplete and decarbonisation becomes existential, Mint Innovation offers a sustainable solution. Mint is a clean technology pioneer, leveraging the world’s fastest growing waste streams and transforming them into value for a greener future. Their patented low-carbon technologies recover critical metals, such as copper, lithium, cobalt, nickel and rare earths from waste streams such as e-waste and spent li-ion batteries. Mint brings its world-first technology to these waste streams in city-scale facilities to return low-carbon metals back into local economies. The technology will help reduce our reliance on unsustainable practices like smelting and mining for mineral recovery, while diverting waste from landfills and preventing the export of hazardous waste to developing nations where it is typically disposed of in dangerous and highly pollutive ways.
