CDR Policy Scoop is back with our next SHOWDOWN, this time on one of the hottest fault lines in carbon markets: should voluntary offsetting require corresponding adjustments?

As Article 6 implementation moves forward, the Voluntary Carbon Market (VCM) faces a pivotal question: are corresponding adjustments NECESSARY for integrity, or OVERKILL, creating a constraint that could choke much‑needed finance for mitigation and removals?

There's a clear rule that corresponding adjustments are required for CORSIA compliance and when credits count toward another country’s NDC, but should that same bar apply when companies use credits for offsetting and net-zero claims?

In the “Necessary” Corner: Olga Gassan‑zade, former chair of the Paris Agreement’s Article 6.4 Supervisory Body and leading expert on carbon markets and international climate policy, arguing that corresponding adjustments are needed to avoid double counting and align the VCM with the Paris Agreement.

In the “Overkill” Corner: Johan Börje from Stockholm Exergi, who very successfully convinced buyers that finance stacking without corresponding adjustments is essential right now. He brings the perspective of a pioneering CDR project developer focused on scaling real‑world removals within evolving policy and market frameworks.

Our co-hosts turned moderators, Eve Tamme and Sebastian Manhart, will keep the conversation sharp, grounded, and accessible: cutting through the jargon and focusing on what this really means for buyers, projects, and host countries.

Noah Deich is back. When he last joined the show in February 2025, the US DOE had just gutted its CDR programmes. This time, he returns to debrief on a very different project: his attempt to build a government-led advanced market commitment for carbon removal, modelled on the GAVI Vaccine Alliance in global health.

He spoke to around two dozen governments. The outcome wasn't what he hoped for, but his diagnosis of why is sharper than you might expect, and it points to a fundamental gap that no country has yet closed.

Noah draws on the history of renewables to explain what CDR policy is still missing, identifies the two interventions he'd prioritise above everything else, and makes the case for why the current political moment, however bleak it looks, may be exactly the right time to be thinking big.

The AMC concept isn't dead. But the path there looks different than it did two years ago.

In this episode, co-hosts Sebastian Manhart and Eve Tamme are joined by Dr Andrew Lenton, Director of CSIRO's CarbonLock Future Science Platform, to discuss Australia's newly published CDR roadmap and its first novel CDR workforce report.

Andrew walks through what it took to build a credible national roadmap and why the coalition of partners, including Google as the sole private sector contributor, may matter as much as the findings themselves. He covers the technologies that surprised him most and what Australia's unique geography means for the CDR opportunity.

The conversation turns to early policy signals: a new Australia-Canada CDR agreement, fresh federal and state-level funding, and how Australia's co-presidency of COP31 is shaping the agenda. Andrew reflects on what it has taken to build basic CDR literacy across government as a foundation for any of this to stick.

The episode closes on workforce, Australia's first novel CDR workforce report just landed, and Andrew outlines the four recommendations at its core. Sebastian brings in data from CDRjobs and European parallels to show why getting this right, and soon, matters.
