SelvaFlux, Inc.

SelvaFlux, Inc. is an American carbon technology company focused on measuring methane uptake through tree bark and developing a methodology that could allow that uptake to be credited in forest-carbon markets. The company describes its work as addressing a gap in standard forest-carbon accounting: methane is the second-largest contributor to current warming after CO₂, and microbes in tree bark remove methane from the air, yet standard forest-carbon methods do not include this uptake. SelvaFlux states that its 2024 Nature study measured this uptake across upland forests, and that it is developing a crediting methodology under which registries could issue credits for bark methane uptake. The company positions itself at the intersection of forest-carbon project development and scientific measurement. According to its website, future credits would require an eligible host project, an approved methane method, measured net uptake above the applicable baseline, and independent verification. SelvaFlux says it would coordinate the independent verification required by the registry under an approved method. It uses satellite and field measurement approaches and states that a patent is pending. SelvaFlux also frames its work around the economics of forest-carbon projects. It notes that forest-carbon developers face costs long before credits can be sold, that credit revenue often falls short of project costs, and that many reforestation projects cannot cover their full development, measurement, and verification costs at current credit prices. It observes that demand for forest credits exceeds high-integrity supply, with buyers making hundreds of millions in advance commitments for nature-based credits while the available supply of high-integrity projects remains limited. The company is led by founder and CEO Alexander Shenkin, PhD, a tropical forest scientist and engineer who led the terrestrial laser-scanning analysis in the 2024 Nature study and leads SelvaFlux's measurement and methodology work. Project Coordinator Amy Wolkowinsky coordinates project planning and field data collection and management, and is Associate Director of Northern Arizona University's Ecosystem Science and Innovation Lab. Advisors include Jane Zelikova, PhD, Executive Director of the Sustainability Research Initiative at the University of Colorado Boulder, and Greg Ives, who advises on project finance, carbon markets, and commercial structure. SelvaFlux invites forest-carbon developers to become pilot partners and to see its proposed crediting process.

SelvaFlux, Inc. is an American carbon technology company that measures methane uptake through tree bark and is developing a methodology that could allow that uptake to be credited in forest-carbon markets. The company's public materials describe its origin in a scientific finding: a 2024 Nature study measured methane uptake through tree bark across upland forests. SelvaFlux states that its founder and CEO, Alexander Shenkin, PhD, led the terrestrial laser-scanning analysis in that study. Shenkin is described as a tropical forest scientist and engineer who leads SelvaFlux's measurement and methodology work; he received the Mulago Foundation's Henry Arnhold Fellowship in 2026. The company's core premise is that standard forest-carbon accounting does not include methane uptake through tree bark, even though methane is the second-largest contributor to current warming after CO₂ and microbes in tree bark remove methane from the air. SelvaFlux measures this uptake and is developing a crediting methodology. Under an approved method, the company says it would coordinate the independent verification required by the registry. Future credits would require an eligible host project, an approved methane method, measured net uptake above the applicable baseline, and independent verification. SelvaFlux states that a patent is pending and that it uses satellite and field measurement. SelvaFlux also addresses the economics of forest-carbon development. It notes that forest-carbon developers face costs long before credits can be sold, that credit revenue often falls short of project costs, and that many reforestation projects cannot cover their full development, measurement, and verification costs at current credit prices. Revenue also begins years after the first expenses, and projects that cannot raise capital during that gap do not proceed. On the demand side, the company observes that buyers have made hundreds of millions in advance commitments for nature-based credits, while the available supply of high-integrity projects remains limited. The company's operating team includes Project Coordinator Amy Wolkowinsky, who coordinates project planning and field data collection and management and is Associate Director of Northern Arizona University's Ecosystem Science and Innovation Lab. Advisors include Jane Zelikova, PhD, Executive Director of the Sustainability Research Initiative at the University of Colorado Boulder, a climate scientist whose published work includes carbon cycling in tropical forest soils, carbon measurement, climate policy, and scientific review of carbon-removal projects; she joined SelvaFlux as an advisor in August 2026. Greg Ives advises SelvaFlux on project finance, carbon markets, and commercial structure and has worked on nature-based carbon projects. SelvaFlux invites forest-carbon developers to become pilot partners and to see its proposed crediting process.
