New research from The Earthshot Prize and the University of Exeter's Green Futures Solutions team, published today, identifies 51 environmental solutions that could drive rapid, transformative change to repair the planet within the next five years. The report, titled "Positive Tipping Points: Accelerating system change to repair our planet," builds on the work of Professor Tim Lenton by applying the concept of positive tipping-point science to all five Earthshots: Protect and Restore Nature, Clean Our Air, Revive Our Oceans, Build a Waste-Free World, and Fix Our Climate. The Earthshot Prize will use the findings to identify solutions with the potential to trigger rapid systems change. One of the key areas highlighted in the research is clean energy, which is acting as a "master cascade." As solar and wind energy have become cheaper, the economics of electric transport, clean buildings, and cleaner air have improved. Over the past decade, the cost of solar power has dropped by around 90%, and as more solar panels are deployed, manufacturing costs continue to fall. This downward spiral of costs has led to more investment and improved technology, making solar power the cheapest source of electricity in most parts of the world. Marine protected areas have also shown self-reinforcing effects, where well-designed and well-enforced ocean conservation efforts have led to visible recovery of fish stocks and biodiversity within a few years. As coastal communities have benefited from these conservation efforts, protected areas have expanded, accelerating progress. This has strengthened food security and climate resilience for coastal populations. An example is the Great Barrier Reef Marine Park in Australia. In January, the High Seas Treaty came into force, supported by over 140 countries, to close the gap in ocean conservation and protect biodiversity in international waters. The research outlines three key prerequisites for success across all five Earthshots: affordability, accessibility, and attractiveness. Solutions must be cost-competitive with current harmful practices, accessible to those who need them, and attractive enough to encourage widespread adoption. A central finding is that the five Earthshots are deeply interconnected, sharing the same conditions, infrastructure, and risks. This means that certain interventions, like the clean electricity cascade, could accelerate positive tipping points across all areas, while barriers like the investment gap in the Global South could hinder progress where it's most needed. Professor Tim Lenton, chair in climate change and Earth system science at the University of Exeter, said, "To reverse damage to our ecosystems before it's too late, we need to unlock positive tipping points, where progress builds on itself, costs fall with scale, and recovery becomes self-propelling." Jason Knauf, CEO of The Earthshot Prize, stated, "For too long, a sense has prevailed that solutions to climate and nature are out of reach. This new research explodes that myth once and for all. Devastating wildfires, extreme heat and floods are a clarion call for change. We must move faster to repair our planet. This pivotal research gives us reasons for optimism. This is a blueprint for turning ambition into action to place our planet on a path of rapid repair. The Earthshot Prize will apply this latest science to find and back the solutions capable of triggering exponential progress for our planet by 2030." Dr. Steven R. Smith, lead author of the report and research fellow in the University of Exeter's Green Futures Solutions team, added, "We looked at 51 solution areas across nature, oceans, air, waste, and climate, and were struck by how progress in one area often depends on progress in another. We're not claiming every system is about to tip. Our report shows where the self-reinforcing mechanisms are and what governments, investors, and innovators can do to unlock them."
