New Research in Nature Reveals Decreasing Carbon Absorption Ability of European Forests

European forests are experiencing a significant decline in their carbon-absorbing capabilities, with a deteriorating trend from a 27% drop between the years 2010-2014 and 2020-2022.

New Research in Nature Reveals Decreasing Carbon Absorption Ability of European Forests

European forests, once effective carbon sinks, are facing a significant decline in their ability to absorb and store carbon dioxide. This decline is primarily due to a combination of increased timber harvesting, climate change-induced extreme weather events, higher incidence of insect infestations and tree dieback, and the prevalence of monoculture forests.

These compounding pressures have reduced tree biomass and impaired growth, directly lowering the forests' carbon sequestration capacity. As a result, the carbon uptake has decreased by approximately 27% between 2010–2014 and 2020–2022, with an even steeper decline noted in 2025.

This decline poses a significant challenge for climate mitigation efforts across Europe. Historically, forests have absorbed about 10% of EU anthropogenic emissions. However, the weakening carbon uptake threatens the EU’s climate targets, including the goal of climate neutrality by 2050.

The European Climate Law aims to cut net greenhouse gas emissions by 55% by 2030. However, if the trend of declining forest carbon sinks continues, the EU's target of 310 million tonnes in net carbon removals by 2030, especially under the Land Use, Land-Use Change and Forestry (LULUCF) sector, will be missed. Reaching climate neutrality by 2050 becomes highly unlikely without a strong and functioning forest carbon sink.

To reverse this decline, five recommended strategies include sustainable forest management, biodiversity-based reforestation, climate-smart forestry, integrated climate and conservation policies, and advanced monitoring and research. Diversification away from monocultures, better monitoring, and reduced greenhouse gas emissions overall are also crucial to restore forest resilience and carbon sink capacity.

Dr. Emily Greenfield, a highly accomplished environmentalist with over 30 years of experience in writing, reviewing, and publishing content on various environmental topics, emphasizes the urgency of these actions. "The decline in the carbon sink capacity of European forests is a serious concern," she says. "We need to act now to protect these vital carbon sinks and ensure the success of our climate mitigation efforts."

The latest findings show that the carbon sink capacity of European forests is weakening, with a 27% drop between 2010-2014 and 2020-2022. If this trend continues, the EU's 2030 and 2050 climate targets, which rely heavily on the LULUCF sector, are at risk. The sector is currently offsetting only 6% of the EU’s total emissions, falling short of the 8% needed.

In conclusion, the combination of human activities (e.g., higher harvest rates) and climate change effects (extreme weather, pests, fires) have reduced European forests' biomass and overall carbon sequestration capacity, threatening their effectiveness as climate buffers and impeding EU climate goals. Urgent action is required to restore these vital carbon sinks and meet the EU's climate targets.
