Correcting a mis-interpreted equation in EW models.

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.

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...

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

Spatial heterogeneity introduces uncertainty when characterizing the Critical Zone, especially when sampling is sparse or requires repeated measurements at the same locations. Here, we layout a probab...

Carbon dioxide removal (CDR) is a necessary component of limiting global warming to 2°C by 2100. Marine enhanced rock weathering (mERW) with minerals like olivine is a CDR strategy with the potential ...

As climate mitigation efforts lag, dependence on anthropogenic CO2 removal increases. Enhanced rock weathering (ERW) is a rapidly growing CO2 removal approach. In terrestrial ERW, crushed rocks are sp...

It is becoming increasingly accepted that annual gigatonne-scale CO2 removal, in conjunction with rapid decarbonization, is necessary to meet international climate goals and limit global warming below...

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 guide to making effective CDR investments.

How to address solar geoengineering’s transparency problem

In November 2024, the Governing Board of the Integrity Council for the Voluntary Carbon Market (ICVCM) approved three methodologies for reducing emissions from deforestation and forest degradation (RE...

In a new study, high-profile climate scientists say countries are using flawed carbon accounting by relying too heavily on trees and oceans to absorb new carbon emissions.

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

[C]Worthy is building a software system – called C-Star – to support standardization of carbon removal accounting and environmental impact assessments related to deployments of marine carbon dioxide r...

Critics say a proposed rule change backed by Amazon and Meta could allow large energy users to hide their true emissions

Climate tech companies can calculate the chances that a flood or wildfire will ravage your home. But what if their odds are all different?

A synthesis of carbon removal estimates from the enhanced weathering literature.

A harmonized database of carbon offset projects and credits.

Energy policy research from the University of Pennsylvania

It uncovered systemic problems with offset markets and recommended that the public university system focus on cutting its direct emissions instead.

There’s a growing disconnect between the governor of California’s words and actions.

Offsetting has been hailed as a fix for runaway emissions and climate change—but the market’s largest firm sold millions of credits for carbon reductions that weren’t real.
