Limiting Overshoot: A new UN climate report demands radical change
As the world approaches 1.5°C of warming, UNEP lays out how rapid emissions cuts, adaptation, and systemic change can still build a safer future.

One Earth
Solutions Hub
Our Solutions Hub brings together the stories, science, and evidence behind the world’s most effective climate and biodiversity solutions. Explore the research, projects, and people restoring nature, transforming energy systems, and regenerating food and fiber production worldwide.
The Hub is organized around the One Earth Solutions Framework, which maps 75+ science-backed solutions across three pillars: Energy Transition, Nature Conservation, and Regenerative Agriculture.
Three Pillars
The three pillars reflect the key system changes we need to achieve collectively to create a vibrant and healthy future.
Explore by Sub-pillar
Within each of the three pillars, climate solutions are organized into four sub-pillars that reflect the sectors where meaningful change must happen at scale.
Energy Transition
Nature Conservation
Regenerative Agriculture
The 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.

On a Razor's Edge: A Narrow Path to 1.5˚C
Read full articleFACT 1
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.
FACT 2
It avoids relying on large-scale speculative engineered carbon removal (e.g. massive BECCS/CCS), limiting removal to nature-based solutions under realistic constraints.
FACT 3
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.
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.

FACT 3
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.

Biochar: Rediscovering ancient wisdom for modern soil health
Read full articleFACT 1
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.
FACT 2
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.
FACT 3
Biochar must be “charged” with compost, manure, or other organic matter before use to prevent it from temporarily depleting soil nutrients.
