DACCUSS at COP30 in Belém
The CDRterra project DACCUSS is participating in several events at the UN Climate Conference COP30 in Belém, Brazil. Together with the European Business Council for Sustainable Energy (e5), the team presents research on Enhanced Rock Weathering (ERW) — a method for CO₂ removal that accelerates the natural weathering of Gabbro and Basalt rocks.
New findings highlight the potential of Gabbro stones from the Global South, especially from Africa and India, which can serve as building materials while their stone dust contributes to CO₂ binding in agricultural and agroforestry soils. DACCUSS illustrates how material use and carbon removal can be combined in practice.
Side Event: Scalable CDR through Enhanced Rock Weathering
📆 Thursday, 20 November 2025, from 15:00 to 16:30
📍Side Event Room 1
“Scalable CDR through Enhanced Rock Weathering (ERW) using Gabbro and Basalt Stones at Gt-scale”
Another side event will take place in the CDR30 Pavilion, which is appearing at a COP for the first time, with the e5 theme.
Speakers from youth initiatives in the Global South, research, industry, and international CDR programs will discuss the role of Enhanced Rock Weathering for scalable CO₂ removal and sustainable development.
📍CDR30 Pavilion and Exhibition in Week 2
📆 Saturday, 15 November 2025, 13:00–14:30
📍CDR30 Pavilion
“Building with Stone, storing CO2 through ERW”
DACCUSS and e5 will contribute with a presentation and panel discussion.
During Week 2 (17–20 November, Booth No. 19), visitors can meet the team at the Exhibition Booth, which highlights new insights on carbon-negative building materials based on Gabbro and Basalt and their potential for Enhanced Rock Weathering.
Research from the CDRterra Consortium
Within the CDRterra consortium, DACCUSS developed an innovative composite material made of plant-based carbon fibers, hard rock, and biochar. The material permanently stores CO₂ and can be used as a carbon-negative wall element. At COP30, the team builds on this research — showing how industrial processes and carbon removal can be integrated for climate-positive construction.
