Releasing downscaled versions of stratospheric aerosol injection simulations, alongside tools to make it accessible.

Exploring meteorological forcing decisions in EW models.

CarbonPlan is a nonprofit organization using science and data to accelerate climate action. Our team analyzes the design and implementation of climate programs across the public and private sector, an...

We are tracking fires in two offset projects enrolled in California’s forest carbon program. These are the first two projects to burn in 2026.

Correcting a mis-interpreted equation in EW models.

We’ve added two new offset registries to OffsetsDB.

We reached for open source tools and cloud-native formats to make climate risk data easily accessible on the web.

We reached for new tools to build a flexible and scalable data pipeline.

We were surprised by the high removal rates claimed in a recent credit issuance to the ERW company Lithos. This post explains what questions the issuance raised for us, and what needs to change to get...

CDR policies must align with a coherent vision of a net-negative world.

Carbon dioxide removal (CDR) is increasingly used to support national targets and corporate net-zero commitments, yet the timing of atmospheric drawdown remains poorly represented in carbon accounting...

We collaborated on a new preprint that establishes clearer language for talking about temporal lags in CDR, and shows how ignoring them can drive near-term warming.

Knowing the location of offsets projects enables more robust market oversight. We’ve added geographic information for 500 forest offset projects to OffsetsDB to assist those efforts.

We updated the Compliance Users tool to include the latest available cap-and-trade program data about who used which offsets in 2024.

At CDRXIV, we want to understand how carbon removal researchers think about preprints. Your responses to this survey will help us gather those perspectives. The results will be anonymized and shared p...

Jeremy reflects on CarbonPlan's first six years, and shares about a moment of growth for the team.

Verra recently acknowledged the existence of millions of excess credits issued to the Kariba REDD+ project. Rather than resolving the issue, Verra’s proposed solution exposes a fundamental structural ...

Five years later, we still don’t know the carbon consequences of the 2020 Lionshead Fire.

Both agricultural liming and enhanced weathering spread crushed rocks on fields and have the potential to remove carbon from the atmosphere. We explore how modifying liming for carbon removal works — ...

Offsets provide few climate benefits and cost California hundreds of millions of dollars each year. When lawmakers reauthorize the state’s cap and trade program this fall, they should eliminate the us...

How we built our platform for research in carbon dioxide removal using open source tools.

We’re relaunching our forest offsets tracking tool for the 2025 North American fire season.

We recently held a workshop on accounting for counterfactual liming in enhanced weathering. Attendees agreed the counterfactual must be considered, but for now there is no single best way to do so.

CDRXIV is a new open access platform for sharing preprints and data related to carbon dioxide removal (CDR).

Isometric’s new protocol for wastewater alkalinity enhancement risks counting decarbonization as carbon dioxide removal. The rules could reshape how carbon removal is defined in other pathways, as wel...

Forest offset projects are starting to measure their impact against real forests instead of unobserved, modeled counterfactuals. This change could improve the integrity of offsets, but data transparen...

Stakeholder survey reveals nuanced views on independent protocol review.

We summarize the ongoing debate around what “counts” as CDR, highlighting the trade-offs of each proposed definition. We suggest an alternative set of questions that can provide a more meaningful guid...

We updated the Compliance Users tool to include the latest available cap-and-trade program data about who used which offsets during the program’s fourth compliance period.

For the first time, a landowner is looking to re-enroll a forest that was part of a project terminated after a catastrophic fire. While this practice is legal, it has potentially negative consequences...

Some carbon removal projects also result in avoided emissions. This is good for the climate, but can pose challenges for individual projects that are trying to earn carbon removal credits.

Early disclosures demonstrate the power of transparency, but also highlight the opportunity for improvements around discoverability and usability.

From our recent webinar with CarbonPlan, learn how voluntary carbon offsets work and how journalists can use OffsetsDB, a data repository.

Upcoming CDR methodologies from the IPCC will provide a blueprint for national reporting of CDR. Now is the time to share evidence.

CarbonPlan is a nonprofit research organization working on improving the transparency and scientific integrity of climate solutions with open data and tools. Our team analyzes the design and implement...
