👏 Shout out to the US Biochar Coalition (USBC) who will be rallying the BCR troops in DC next month to continue to raise federal and legislative awareness of the tremendous benefits of biochar. Stay tuned! 8/8

🧐 Could this pragmatic, co-benefit-driven approach be the most viable path forward for large-scale CDR policy adoption in the US? What are your thoughts? 7/8

📜 This type of bill might be indicative of how future CDR-related policy could be successful in this new political era. Not as standalone climate policies, but as integrated components within broader forestry, land management, economic development, and agricultural legislation. 6/8

🤩 While BCR is by no means the main character, the bill does:
▪️ Mandate establishment of biochar demonstration projects
▪️ Maximum 35% of capital costs covered
▪️ At least 50% of feedstock must come from forest thinning. 5/8

🧯 While BCR’s role in carbon sequestration and carbon dioxide removal (CDR) is acknowledged, it is not the bill’s central driver. The Act highlights biochar as a critical tool in conservation, wildfire prevention, and land restoration. 4/8

Yet, in this bill, there are also strong provisions for biochar carbon removal (BCR).
⚡ With cosponsors from both parties, the bill moved with lightning speed through the House, passing with a 279-141 vote and will now pass onto the Senate. 3/8

🌲 In January, the bipartisan Fix Our Forests Act (H.R.471) was introduced by Representative Bruce Westerman into the new Congress. The legislation focuses on mitigating wildfire risks, restoring forest resilience, and improving stewardship through collaborative and science-driven approaches. 2/8

🫧 Moving forward, the collective challenge we face is how to move beyond our bubble. How do we reach people who have never heard of CDR and educate them on the benefits, potential, and urgency? I spend a lot of time thinking about this one. If you have good ideas, please do share them. 8/8

🌍 And so I am personally doubling down on LinkedIn as well as my newsletter and podcast - platforms I have come to appreciate massively for helping to grow a community of like-minded CDR professionals. 7/8

🏃 While the data is a testament to how far we’ve come and the foundational role that Twitter played in building awareness, I – like many others – decided to leave it in 2024. 6/8

🌲 Conventional CDR or nature-based CDR clearly still gets the lion share of attention on social media, with soil carbon sequestration alone having a larger share than all novel / tech CDR taken together.

So where does this leave us? 5/8

👍 By 2022, 24.9% of tweets about CDR were positive (vs 10.7% negative) with biochar emerging as one of the most positively perceived of the ‘novel methods’ compared to DAC, which had a higher share of neutral or mixed sentiment. 4/8

What did they find?

🐦 They found that tweets mentioning CDR grew exponentially, with a median annual growth rate of 32% between 2010 and 2022. This increase outpaced general climate change tweets. 3/8

📈 A study in Nature by Repke et al. (2024), analysing Twitter discourse on CDR from 2010 to 2022, discovered an exponential growth in both public attention and increasingly positive sentiment towards CDR solutions. 2/8

😲 Also, this was our tenth episode of the CDR Policy Scoop. Over 11,000 people watched our lives/recorded session here on LinkedIn and our recently launched podcast got 1,000 downloads already. 4/4

💪 Noah provided tangible advice on what you, on what all of us, can and should do today to keep moving CDR forward in the U.S.

🙏 A huge thanks to all of you. If you haven’t yet, please do subscribe to the podcast and leave us a review - it helps a lot. 3/4

🌤️ There is so much uncertainty around the future of carbon removal in the United States. Noah Deich’s comments in the latest CDR Policy Scoop were refreshing, pragmatic, and - crucially - action oriented. 2/4
