Concrete Climate Action: How Biochar Is Turning Buildings into Carbon Sinks
What if the buildings around us could help remove carbon from the atmosphere?
The construction industry is one of the world’s largest sources of embodied carbon — but it is also emerging as a promising frontier for durable carbon removal. By integrating biochar into concrete, asphalt, and other building materials, we can turn part of the built environment into a long-term carbon storage solution.
Join leaders and field experts from Carbon Standards and CarStorCon for a conversation on how biochar-enhanced building materials are helping transform the way we think about carbon removal and construction.
In this webinar, we’ll explore:
– The fundamentals of biochar-enhanced concrete and asphalt
– Certification pathways for ensuring verifiable and durable carbon storage
– The opportunities and challenges of scaling biochar-based carbon removal across the built environment
Join us to discover how one of the world’s biggest carbon challenges could become part of the solution — built right into the walls, roads, and structures around us.
The session will be recorded, and the recording will be available exclusively to event registrants and IBI members after the event.
Amy Rhoades is Chief Communications & Engagement Officer at Carbon Standards International, where she leads communications strategy, stakeholder engagement, and market positioning for the carbon removal standards body.
Before joining Carbon Standards, she spent over a decade with the UN leading large-scale communications and behaviour change programmes across complex environments – working for the UN Migration Agency (IOM), the International Labour Organization (ILO), and the Inter-American Development Bank (IADB). She has provided communications training and worked alongside regional and country teams in more than 40 countries and previously lived in Haiti, the Dominican Republic and the Philippines.
She is co-founder of Lost Glacier, an off-grid Alpine centre for climate resilience building practical pathways for carbon farming and carbon removal. Amy holds an MA in International Law and Human Rights from the Universidad para la Paz in Costa Rica and a BA from Colgate University, New York.
Robin Werren is Product Manager for the Construction C-Sink and Biochar C-Sink Standards at Carbon Standards, where he works on implementing and certifying carbon removal projects worldwide. He trained originally as a carpenter before spending years in construction across Switzerland and abroad, giving him a hands-on foundation in sustainable building practice. He went on to study Wood Technology Engineering at Bern University of Applied Sciences, specializing in sustainable product and process management, and later worked in CDR tech start-ups focused on afforestation, biochar, and construction projects in the Global South. Before joining Carbon Standards, he worked in bio-based product innovation for construction and CDR methodology development. Robin brings a rare combination of a scientific mindset and technical engineering to the question of how we build a climate positive future.
Thorsten Groeneveld studied business law. After 10 years, in a law firm specializing in business succession, he decided 2023 to leave the field and looked for a new role in an area that serves to preserve the planet. He became part of the newly founded start-up CarStorCon Technologies as the second managing director responsible for the entire administrative area. CarStorCon® stands for Carbon Storage Concrete. This carbon-storing concrete is produced using the specially developed aggregate Clim@Add®, which is based on technical carbon from pyrolysis plants. CarStorCon Technologies has grown in the last years and currently supports many projects in concrete and asphalt plants.
