Abstract
As the urgency to address climate change intensifies, the exploration of sustainable negative emission technologies becomes
imperative. Enhanced weathering (EW) represents an approach by leveraging the natural process of rock weathering to
sequester atmospheric carbon dioxide (
CO2) in agricultural lands. This review synthesizes current research on EW, focusing
on its mechanisms, influencing factors, and pathways for successful integration into agricultural practices. It evaluates
key factors such as material suitability, particle size, application rates, soil properties, and climate, which are crucial for
optimizing EW’s efficacy. The study highlights the multifaceted benefits of EW, including soil fertility improvement, pH
regulation, and enhanced water retention, which collectively contribute to increased agricultural productivity and climate
change mitigation. Furthermore, the review introduces Monitoring, Reporting, and Verification (MRV) and Carbon Dioxide
Removal (CDR) verification frameworks as essential components for assessing and enhancing EW’s effectiveness and credibility.
By examining the current state of research and proposing avenues for future investigation, this review aims to deepen
the understanding of EW’s role in sustainable agriculture and climate change mitigation strategies.
