NATURE RESTORATION IS NO SUBSTITUTE FOR STEEP EMISSION REDUCTIONS

The document assesses the role of nature restoration in climate mitigation, citing a University of Melbourne study to demonstrate that land-based carbon removals cannot substitute for the phase-out of fossil fuels. While nature restoration provides ecological benefits and can remove 100 GtC by 2100, this only offsets 15% of the 650 GtC projected to be released under current government policies. The brief emphasizes that the lag time for land sequestration means these activities have minimal impact on peak temperatures, which are expected within 10–20 years. To achieve the Paris Agreement's 1.5°C goal, the author argues for prompt fossil fuel emission reductions of 85%–98% alongside nature restoration and the halting of deforestation.

• Nature restoration has a limited capacity to offset planned emissions; it could remove 100 GtC by 2100, whereas current government policies are projected to release approximately 650 GtC in the same period, meaning only 15% of planned emissions would be offset.
• The impact of nature restoration on global temperatures is minimal, potentially lowering peak temperatures by 0.01°C and average temperatures in 2100 by 0.1°C, which is insufficient to reach the 1.5°C Paris Agreement goal given current trajectories toward 3°C of warming.
• There is a significant time lag of approximately 20 years between land-management interventions and actual carbon removals, meaning nature restoration cannot effectively reduce peak warming, which is expected to occur within the next 10–20 years.
• To limit warming to 1.5°C, nature restoration must be combined with deep decarbonization scenarios that include reducing fossil fuel emissions by 85%–98%, achieving a steep reduction before 2030 and global net-zero emissions by 2050.
• Halting deforestation by 2030 has a negligible effect on peak mid-century temperatures but can reduce warming over the century by approximately 0.08°C.
