From Climitigation to the field
Project Vesta
The public record of a climate idea moving from a think tank, to its first coverage and customer, to funded research and field deployment.
The project
Climitigation identified coastal enhanced weathering as an underfunded carbon-removal pathway. Project Vesta was founded to move that idea out of the literature and into carefully monitored real-world trials.

Project Vesta begins inside Climitigation
Climitigation's search for overlooked, scalable carbon-removal approaches led to coastal enhanced weathering. Project Vesta was formed to assemble the science, funding, and fieldwork needed to test it.
Vesta describes 2019 as its founding year.

Mother Jones includes Vesta in the climate intervention debate
A Project Vesta press record preserved the magazine's description of olivine beaches as a proposed way to accelerate a carbon-removal process that normally unfolds over geological time.
Date shown is the Vesta archive date.

$1.6 million supports the scientific roadmap
Additional Ventures awarded Project Vesta a $1.6 million grant for laboratory and field studies, scientific hiring, and groundwork for its first beach pilot.
The December 2020 grant was announced March 16, 2021.

The CarbonCycle installation enters the public archive
An Eric Matzner archive film preserves the Project Vesta talk and CarbonCycle artwork presented at Planet Home EcoFestival, connecting the geochemistry to a public-facing installation.
Date shown is the archive upload date; the installation predates it.

Peer-reviewed field study reports no oyster safety concern
The one-year Southampton field study found no significant difference in oyster biomass or mean metal accumulation between olivine and control treatments. Metal concentrations remained below FDA warning thresholds and within global natural ranges.
