Methods for determining the CO2 removal capacity of enhanced weathering in agronomic settings

Recent analysis by the IPCC suggests that, across an array of scenarios, both GHG emissions reductions and various degrees carbon removal will be required to achieve climate stabilization at a level that avoids most dangerous changes in future. Among large number options realm natural solutions, atmospheric dioxide (CDR) via enhanced silicate weathering (EW) global working lands could, theory, billions tons CO 2 each year. Despite such potential, however, scientific verification field testing this technology are still need significant advancement. Increasing EW trials can aided formal presentation effective study designs methodological approaches quantifying removal. In particular, studies require interdisciplinary “convergence” research links low temperature geochemistry agronomy. Here, drawing on geologic agronomic literature, as well demonstration-scale EW, we provide overview (1) existing literature experimentation technique, (2) studying settings, (3) bases tradeoffs behind techniques for other relevant methodologies, (4) attributes stakeholder engagement translating action. doing so, guide establishing trials, thereby advancing through convergence
