Sessions
Join us at ERW25, the third annual Enhanced Rock Weathering Conference, held at the University of Antwerp. This conference brings together experts in the field to discuss a wide range of topics such as weathering processes and CO2 removal, environmental effects, costs and implementation aspects. Presentations will focus on five main research topics, these five sessions provide the main structure for the ERW25 conference.
Session 1: Terrestrial enhanced weathering
Enhanced weathering techniques in terrestrial conditions must strike a balance between preserving, or increasing, agricultural productivity or natural ecosystems while supporting climate mitigation. This session focuses on innovative research examining the benefits and risks of enhanced rock weathering on land. We invite contributions that explore current methodologies and findings to promote sustainable land management practices. We especially encourage studies on ERW impacts on organic carbon dynamics.
Session 2: Novel methods & Engineering-based approaches
A wide variety of experimental approaches are currently used to evaluate carbon removal rates (CDR) of ERW. Experiments exploring novel methods are being conducted in both controlled settings (e.g. reactors) and natural environments. This session invites submissions on innovative technologies for accelerating mineral dissolution, integrating CDR techniques, and engineering solutions across ecosystems, aiming to showcase breakthrough methods that optimize ERW as a scalable climate change solution.
Session 3: Enhanced rock weathering at scale: life cycle assessments, policy frameworks, and societal perspectives
Public awareness, balance between (carbon) costs and profits, and science-based policy making will be crucial to ensure successful upscaling of ERW. This session discusses current policies, along with those required in the future, to regulate and/or promote ERW at national and international levels. Additionally, this session will explore the ethics and feasibility of ERW, including how its benefits and burdens can be evaluated using LCA analyses and be distributed among stakeholders and decision-makers.
Session 4: Advancing MRV practices for enhanced rock weathering
Accurate assessment of the achieved net carbon removal through ERW remains challenging and heavily debated. In order to achieve reliable quantification of carbon removal efficiencies and for implementation of a science-based carbon credit system, the establishment of a rigorous and standardized MRV framework is crucial. This session will explore the latest advancements, challenges, and future needs for MRV of terrestrial and marine ERW.
Session 5: Mineral-based ocean alkalinity enhancement
A wide portfolio of minerals and industrial by-products are being considered for increasing ocean CO₂ sequestration by ocean alkalinity enhancement. Yet the ecological impacts and CO₂ sequestration potential of these various minerals remains largely unknown. By combining insights from geochemical and ecological experimental research, this session will explore the scalability of mineral-based ocean alkalinity enhancement and its impacts on global carbon budgets and marine ecosystems.
