As world leaders gather at COP29 to consider reducing emissions, the latest global carbon budget shows CO₂ emissions from fossil fuels are still going up, not down, despite some promising signs.
It’s vital we find cost-effective ways to get and keep more trees in the ground. Our research looked at where natural regeneration is likely to be successful due to environmental conditions.
Planting millions of trees in natural grassland is largely ineffective in the battle against global warming because it adds little or no additional carbon storage.
The most comprehensive Australian carbon budget assessment completed to date shows the nation flip-flops from source to sink of carbon emissions, depending on the prevailing conditions.
It might seem counterintuitive to suggest timber harvesting when the goal is to restore forests, but that gives landholders the economic incentive to protect and manage forests over time.
Record emissions are fast shrinking the remaining amount of carbon dioxide we can emit if we are to limit global warming. At current rates, we’ll use up the budget for a 1.5°C outcome in seven years.
Climate modelling that best accounts for the processes that sustain plant life predicts plants could absorb up to 20% more CO₂ than the simplest version predicted.
Native trees have been found at new heights in the Scottish Highlands, demonstrating how mountain woodland could recover from deforestation – benefiting humans, wildlife and climate issues.

Can planting trees help us solve the climate crisis? Probably, but to what extent?
New research finds nature restoration only marginally lowers global warming. This pours cold water on the idea of using carbon offsets to solve the climate crisis.
Planting trees and preventing deforestation can store carbon in nature, but the effect may only be temporary. If we also eliminate emissions from fossil fuels, even this temporary effect is important.
