Carbon research is most powerful when it links mechanistic ecology to complete mass balance and then connects that evidence to future risk and environmental decisions. The following conclusions provide a compact guide to the full report. 1 Carbon is simultaneously a structural element, an energy carrier, a biogeochemical currency, and a climate-active substance. Its ecological meaning cannot be reduced to atmospheric CO₂. Carbon moves among living biomass, detritus, soils, fresh waters, wetlands, oceans, rocks, fuels, and human products, and each pool is governed by distinct controls and residence times.   2 The carbon cycle has been transformed from a near-balanced natural cycle into a strongly perturbed Earth-system budget. For 2024, total anthropogenic CO₂ emissions were estimated at 11.6 ± 0.9 GtC, while the atmospheric increase, ocean sink, and land sink were 7.9 ± 0.2, 3.4 ± 0.4, and 1.9 ± 1.1 GtC, respectively. The unusually weak land sink illustrates the sensitivity of natural uptake to climate variability and extremes (Friedlingstein et al., 2026a).   3 Carbon research has no single founder; it emerged from several cumulative scientific lineages. Van Helmont and Black helped distinguish carbon dioxide from ordinary air; Lavoisier placed carbon within modern elemental chemistry; Priestley, Ingenhousz, Senebier, and de Saussure established plant–atmosphere carbon relations; and later work connected carbon to ecosystem energetics, climate physics, global monitoring, and Earth-system feedbacks.   4 Research progress has come from integration across scales rather than from one dominant method. Long atmospheric records, ecosystem experiments, eddy covariance, inventories, isotopes, remote sensing, atmospheric inversions, autonomous ocean observations, genomics and other molecular approaches, and Earth-system models now constrain different parts of the cycle. FAIR data, common protocols, and reproducible workflows increasingly make those lines of evidence interoperable. Their disagreement is scientifically useful because it identifies missing processes and scale mismatches.   5 The frontier has shifted from estimating pool size to explaining vulnerability, persistence, reversibility, and intervention risk. Current priorities include disturbance-driven sink loss, irrecoverable carbon, agroforestry and restoration outcomes, deep-soil carbon, microbial carbon-use efficiency and necromass, abrupt permafrost thaw, methane hotspots and oxidation, lateral land–water–ocean transport, blue carbon, nutrient constraints, and the climate sensitivity of land and ocean sinks. Microbiome engineering and biological methane filters are promising but remain validation-intensive research areas.   6 Carbon management must be evaluated as a systems and transition problem. A credible intervention requires explicit baselines, additionality, durability, leakage, lifecycle emissions, uncertainty, monitoring, biodiversity and water safeguards, and social legitimacy. Point-source carbon capture and storage can avoid emissions without constituting atmospheric removal; carbon utilization is durable only when product fate and storage time support the claim; and land-based or engineered carbon dioxide removal must be reported net of associated emissions. Carbon management should complement rapid emissions reduction and be governed through a just transition that addresses workers, land rights, energy access, participation, and distributional outcomes (Bui et al., 2018; Edwards et al., 2026; Healy and Barry, 2017).
