Nature based solutions: CO2 removals in 2022?
Is the nascent market for nature-based carbon offsets working? We appraised five projects in 2022, and contributed $7,700 to capture 440 tons of CO2, which is 20x our own CO2 footprint. This 11-page note presents our top five conclusions. Today’s market lacks depth and efficiency. High-quality credits are most bottlenecked. Prices rise further in 2023.…

CO2 offsets: Pachama’s AI platform?
Pachama is a nature-based technology company, which has raised $79M, to create a portal where buyers can choose “from rigorously vetted forest restoration and conservation projects”, which in turn are tracked using proprietary AI. This data-file evaluates Pachama’s portfolio and our own experiences, using our usual framework for assessing nature-based CO2 removals.

Tigercat: forestry and timber innovations?
Tigercat is a private company, founded in 1992, headquartered in Ontario, Canada, with c2,000 employees. The company produces specialized machinery for forestry, logging, materials processing and off-road equipment. Our patent review has found a moat around reliable, easy-to-maintain, mobile and efficient forestry equipment.

Energy history: how much wood can be cut in a day?
How much wood can be cut in a day? We review 500-years of industrial history. In medieval times, a manorial tenant might have gathered 250kg of fallen branches in a day. A modern feller-buncher is 150x more productive. But a modern energy analyst is little better than a medieval peasant, and harvesting wood as a…

CO2 removals: teak plantations, Nicaragua?
We reviewed a reforestation initiative, which should absorb 100,000 tons of CO2 from the atmosphere, by row-planting teak on former pasture land in Nicaragua. The project scores 70/100 on our five-point framework. But it also illustrates key debates for nature-based CO2 removals.

Biodiversity: a breakdown of species and carbon stocks?
550GT of Carbon is stored in the living biomass of 40M species currently inhabiting planet Earth. About 70,000 are vertebrate species and 6,000 are mammal species. What implications for biodiversity, climate change and nature based solutions?

Carbon offsets: cost of CO2 removal per tree planted?
What is the cost of CO2 removal by planting trees? This calculator assesses different types of trees, types of planting, survival, permanence and discounting. A good ballpark range is $15-30/ton. Verified CO2 removals are likely higher cost but higher quality offsets.

CO2 Removals: BaumInvest Mixed Reforestation, Costa Rica?
We have reviewed the BaumInvest Mixed Reforestation Project in Costa Rica, on a framework for de-risking nature-based CO2 removals. As a result, we have purchased 67 tons of CO2 removals from the project, at $45/ton, for a total of $3,015 in July-2022.

Savanna carbon: great plains?
Savannas are an open mix of trees, brush and grasses. They comprise up to 20% of the world’s land, 30% of its CO2 fixation, and their active management could abate 1GTpa of CO2 at low cost. This 17-page research note was inspired by exploring some wild savannas and thus draws on photos and observation.

Palm oil: what CO2 intensity?
Global palm oil production runs at 80MTpa, for food, HPC and bio-fuels. Carbon intensity is 1.2 tons CO2e per ton of crude palm oil, excluding land use impacts, and 8.0 tons/ton on a global basis including land use impacts. This means once a bio-fuel has more than c35% palm oil in its feedstock, it is…
