Briefings

A 2026 model project indicates that a substantial loss of plant diversity in grasslands worldwide could reduce CO2 absorption by approximately 15% by midcentury. This decline would occur even if diversity were maintained in other ecosystems, highlighting the specific vulnerability of grassland carbon sinks to species loss.

Key points

• A substantial loss of plant diversity could cause grasslands worldwide to absorb around 15% less CO2 by midcentury compared to a scenario with maintained diversity.

Context and limitations

The evidence is limited to a 2026 model project and does not include historical data, specific regional variations, or long-term climate projections beyond midcentury.
