Kieger's Climate Action

InPlanet operates in Brazil as the first Enhanced Rock Weathering startup solely focused on the tropics. They spread silicate rock powder under ideal soil and climate conditions, promoting rapid weathering and carbon capture. The carbon is stored in soil leachates, waterways, and ocean sediments. Key co-benefits include the restoration of degraded soils, improved food nutrition, and reduced reliance on conventional chemical inputs in agriculture. InPlanet conducts rigorous measurements, from laboratory to field, to assess the net carbon removal effectiveness of rock spreading in various agricultural contexts.

Nitrous oxide (N₂O) is one of the most difficult greenhouse gases to mitigate. Today N₂O from agriculture contributes ~2.3 GtCO₂e per year with few mitigation options. Crop Intellect has developed R-Leaf, a novel foliar spray that uses photocatalysis to break down nitrous oxide into inert nitrogen and oxygen directly in the field. This project will undertake the first large-scale, independently verified deployment of R-Leaf. Spanning 5,000 hectares of cereal crops, the trial will be monitored by independent researchers from either the UK Centre for Ecology & Hydrology (UKCEH) or the University of Lincoln. The study aims to generate the first robust field data on atmospheric N₂O removal, assess agronomic co-benefits, and establish a transparent methodology for future crediting under international carbon frameworks. The receiving entity is Crop intellect, a UK-startup, they in turn will fund the independent third-party academic partner as well as other project costs.

The Kawsay Ñampi project, led by the Kichwa People of Sarayaku in the Ecuadorian Amazon, protects 142,500 hectares of intact rainforest through Indigenous governance and modern monitoring tools. The project is developed under the Climate Justice Standard, which ensures that the project channels most funds directly to community priorities while piloting an ethical, non-offset Climate Justice Contribution model. It offers a replicable pathway for Indigenous-led, high-integrity climate and biodiversity solutions.
