Directory

This violin plot sorts every pure-play CDR company in the Directory by its pathway (columns) and its headcount (vertical axis, log scale from 1 to 100+). Each dot is one company, coloured by its current liveliness tier — Active, Moderate, Suspect, or Likely Dead. The grey shape behind each column is the size distribution: where it bulges, that’s where most companies in that pathway sit. The value here is comparative. A raw company list tells you who exists; this view tells you where the weight sits. Pathways with most dots stacked at the bottom are dominated by sub-10-employee firms — many small entrants, few that have grown. Pathways with dots reaching up the column have produced operators that scaled past the founder-and-a-few-engineers phase. Colour (not vertical position) is what tells you the health story: red dots high up the column mean a sizeable operator went quiet; red dots on the floor are the long tail churning as it always has. ...

This chart tracks CDR researchers over time on a diverging axis. Above the line are researchers who published a CDR-relevant paper that year (active), stacked upward; below the line are dormant researchers, split into those who published the previous year and those who published only earlier. New entrants join at the base of the active band each year as a teal block. The top envelope is the real, working research workforce each year — the number of people actually publishing, not the cumulative head-count. ...

This chart plots every pure-play CDR company in the Directory as a single dot. The horizontal axis is the company’s founding year (estimated from its primary domain registration), the vertical axis is its current headcount on a log scale, and the colour codes the company’s pathway. The shaded blue background traces overall company density — darker patches mark where the crowd of pure-plays sits. The value here is shape, not ranking. A bar chart would tell you how many companies exist in each pathway; this view tells you the entire industry’s growth contour at one glance — when did the wave of small startups hit, where are the rare big older operators, what cluster sits on the floor of “still under five people”. Outlier dots near the top of the chart are the names everyone already knows; the dense low band is where most of the industry actually lives. ...

This chart is a stacked horizontal bar showing CDR-attributable headcount across pathways on the vertical axis, with each bar segmented by business focus: pure-play companies whose entire reason for existing is CDR, divisions inside larger firms where CDR is one line of business, and “ecosystem” firms, the directory’s label for companies that sell tools, verification, brokerage, or software to those operators. Bar length is total attributed workers; the color split is where those workers actually sit. ...

Each dot on this scatter is a single CDR pathway - direct air capture, enhanced rock weathering, biochar, ocean alkalinity, mineralization, and the rest. The horizontal axis counts how many companies are working that pathway; the vertical axis sums the employees across those companies. Linear scales on both, so distance on the page matches distance in the numbers. What this view reveals that a headcount table cannot is the shape of the industry. A pathway sitting high and to the right is crowded with firms and staffed deeply. One sitting high but to the left is a pathway dominated by a few large companies. Low and to the right means many small teams chasing the same idea. The spread between these corners is the story of where capital and talent have actually landed, versus where the field is still a cottage. ...

This is a horizontal bar chart ranking the twelve largest pure-play CDR companies by employee headcount, with each bar coloured by the primary removal pathway the company pursues (DAC, mineralisation, biomass, ocean, and so on). Pure-play means the company’s core business is carbon removal, not a side project bolted onto an existing industrial firm. For anyone tracking the sector, this is the quickest way to see where the human capital actually sits. Headcount is a slower, harder signal than press releases or announced offtakes - it reflects real hiring, real payroll, real conviction from investors. The pathway colouring shows whether the talent concentration lines up with where delivered tonnes are going, or whether one approach is staffing up well ahead of its removal track record. ...
