On a Razor's Edge: A Narrow Path to 1.5˚C
An updated 1.5 °C mitigation pathway based on post-COVID emissions, real deployment rates, and nature-based removal.
One Earth provides tools and resources to help philanthropists, investors, policymakers, and everyday citizens create impact where it matters most.
One Earth's solutions are science-backed actions that improve life for people and the planet. By changing how we grow food, use energy, and protect nature, they create a fairer, safer future for all.
Explore the FrameworkThe first energy transition sub-pillar of renewable power refers to electricity generated from carbon-free or carbon neutral sources that are naturally replenishing and virtually inexhaustible or sustainable over the long term.
The second energy transition sub-pillar of renewable heat refers to heating water, buildings, and industrial processes using carbon-free or carbon neutral sources that are naturally replenishing and virtually inexhaustible or sustainable over the long term.

Where is nearly $400 billion in climate funding going…and where is it falling short?
Unlike many high-ambition climate models, the One Earth “razor’s edge” scenario explicitly incorporates the rebound of fossil fuel emissions since 2020 (after the COVID-related dip) and uses a reduced carbon budget.
It avoids relying on large-scale speculative engineered carbon removal (e.g. massive BECCS/CCS), limiting removal to nature-based solutions under realistic constraints.
The model’s “warm-up” phase (2025–2030) depends on locking in the post-2024 emissions peak, scaling up renewables, retiring coal rapidly, and ensuring that all new power additions are renewable.
Land conservation refers to the long-term protection and Indigenous governance of ecosystems occurring within terrestrial boundaries across all biome types—tundra, boreal forests, temperate forests, tropical forests, scrublands & savannas, grasslands, deserts, wetlands, and freshwater bodies (lakes and rivers).
The long-term protection and sustainable management of marine areas and species — from coastal ecosystems and coral reefs to deep ocean habitats.
Through decades of groundbreaking research and advocacy, Dr. Jane Goodall revolutionized our understanding of animals and inspired generations to protect nature by combining science and compassion.

The Bioregions framework maps the planet into 185 ecological regions across 14 realms, enabling place-based climate and conservation planning.
AskNature offers over 1,700 examples of how organisms solve challenges, providing inspiration for sustainable human design.
Combining bioregional mapping with nature’s strategies helps communities create locally adapted and resilient climate solutions.
A wide variety of farm management techniques that increase crop resilience and the net carbon stored in farmland, decrease food-miles and inputs while increasing yields, and eliminate the emissions associated with fertilizer.
Shifting diets to decrease the strain on our rangelands as well as managing pastureland to decrease methane emissions and maximize carbon stored in the soil by eliminating deforestation and increasing ecosystem health.

Claire Ring, founder of Cocoplum, transforms recycled pill bottles into stylish, circular sunglasses—proving that sustainable design can tackle plastic waste and spark industry change.
Amazonian Terra Preta soils, enriched with charcoal and organic waste, remain fertile for centuries and can contain up to 18 times more carbon than untreated soils.
A single gram of biochar can have an internal surface area of about 9,000 ft², providing vast space for microbes, nutrients, and water storage.
Biochar must be “charged” with compost, manure, or other organic matter before use to prevent it from temporarily depleting soil nutrients.
