European Forests’ Carbon Sink Drops a Third, Jeopardizing EU Net-Zero Plans

Sharper-than-expected losses in CO₂ absorption exposed by fresh 2025 data threaten the EU’s reliance on forests to offset hard-to-cut emissions.

Overview

  • A new paper from the EU Joint Research Centre finds European forests absorbed around 332 million tonnes of CO₂ annually in 2020–22, nearly a third less than during 2010–14.
  • Preliminary 2025 data from EU member states indicate an even steeper drop in forest carbon uptake beyond the JRC figures.
  • Increased logging, droughts, wildfires and pest outbreaks are degrading forests and undermining their carbon storage capacity.
  • Current land and forestry sinks offset roughly 6 percent of the EU’s greenhouse gas emissions, about 2 percentage points below the level projected for 2050 net-zero targets.
  • Scientists call for immediate emission cuts, adaptive forest management and real-time monitoring to restore sink resilience and uphold climate goals.
