A new study from Lund University has revealed that old-growth forests provide greater climate benefits than previously understood, according to research published on March 19, 2026. The study, led by researcher Anders Ahlström from the university's Department of Environmental and Geosciences, represents nearly a decade of work on forest ecosystems and their role in climate regulation. While specific details about the research methodology and exact findings were not provided in the available source, the study suggests that undisturbed, mature forests may play a more significant role in carbon storage and climate mitigation than earlier estimates indicated.
The research was reported by Sweden's public broadcaster Sveriges Radio, highlighting the ongoing scientific work at Swedish universities to better understand natural climate solutions. Further details about the study's publication venue and specific data were not immediately available.
