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. ...

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 DAC researchers over time on a diverging axis. Above the line are researchers who published a DAC-relevant paper that year (active); 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. DAC is direct air capture, the most capital- and headline-heavy pathway. The top envelope is the number actually publishing in the pathway each year. ...

This chart tracks Enhanced Weathering researchers over time on a diverging axis. Above the line are researchers who published a Enhanced Weathering-relevant paper that year (active); 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. Enhanced Weathering is one of the youngest and fastest-growing pathways. The top envelope is the number actually publishing in the pathway each year. ...

This chart tracks Soil Carbon researchers over time on a diverging axis. Above the line are researchers who published a Soil Carbon-relevant paper that year (active); 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. Soil Carbon is the largest pathway by headcount, sitting closest to mainstream soil science. The top envelope is the number actually publishing in the pathway each year. ...

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 players who sell tools, verification, brokerage, or software into the space. Bar length is total attributed workers; the color split is where those workers actually sit. ...

This chart is a stacked bar count of every company in the CDR Directory, grouped along the x-axis by removal pathway (direct air capture, enhanced weathering, biochar, ocean alkalinity, and so on), with each bar segmented by business focus: pure-play producers, brokers and marketplaces, and firms where CDR is a side business bolted onto a different core model. The total height tells you which pathways are crowded with company formation. The segment mix tells you something a raw count hides: whether a pathway’s apparent size is built on operators actually delivering tonnes, on intermediaries reselling them, or on incumbents whose CDR line is a minor adjunct. Two pathways with identical totals can have very different underlying economies once you see the split. ...

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 tracks Soil Carbon researchers over time on a diverging axis. Above the line are researchers who published a Soil Carbon-relevant paper that year (active); below the line are dormant researchers, split into those who published the previous year and those who published only earlier.

The top envelope is the number actually publishing in the pathway each year. ...

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. ...
