Even as trees photosynthesize late into the year, their growth stops by mid-summer, which impacts their carbon uptake.

New Research Indicates That in the Future, Trees May Store Less Carbon Than Expected
Abatify Summary
Nature & Climate Perspective
**The premature cessation of tree growth relative to late-season photosynthesis reveals a systemic overestimation of forest carbon sequestration capacity, threatening long-term ecological stability. **
- Asynchronous photosynthesis and wood formation (xylogenesis) mean that late-season carbon uptake does not translate to permanent biomass, altering traditional LULUCF net-sink projections.
- The physiological disconnect reduces the expected carbon residence time in forest ecosystems, leading to faster carbon cycling back into the atmosphere rather than stable wood storage.
- This mechanism calls into question the projected resilience of nature-based solutions (NbS) under escalating climate stress, as thermal and water limits halt structural growth earlier than expected.
Market & Policy Outlook
**This research directly challenges the 'robust quantification' and 'permanence' criteria of the ICVCM Core Carbon Principles, triggering a necessary revaluation of forestry offsets in global carbon markets. **
- Under current ICVCM CCP guidelines, carbon credits must reflect conservatively quantified emissions reductions; overestimating biological sequestration rates risks invalidating legacy forestry-based ITMOs under Article 6.2 and 6.4.
- Market pricing for forestry-backed offsets is likely to face downward pressure, forcing registries to increase buffer pool requirements to hedge against lower-than-expected actual carbon storage.
- Corporate compliance buyers targeting SBTi net-zero alignment must re-evaluate their Scope 3 neutrality roadmaps, potentially shifting capital away from afforestation toward high-permanence technical removals.
