  • Fresh insight on the War on the Planet

    Track changes provides fresh voices on and ways of seeing. I have been listening to the discourse for decades almost till I’m despairing and immune to the horror of fossil fuel war on our planet and us. But the people speaking here offer knowledgeable, rational understanding in language that speaks directly to everyone.

Talking Points

Recent interactions between the hosts and their guests.

ISO's net zero standard: Five things you need to know
Q: What's the role of removals vs reductions in the standard, and when should organizations start planning for removals?
Removals are emphasized as part of the plan once reductions have been pursued as deeply as possible; the standard encourages early planning for removals, with considerations for durability, additionality, and avoidance of carbon leakage to ensure long-term confidence in offsets or removals.
ISO's net zero standard: Five things you need to know
Q: How does ISO link the global net zero concept to national or sectoral frameworks?
It creates a framework that differs by boundary (organizational vs jurisdictional) and emphasizes ambition and equity, allowing organizations to demonstrate leadership while recognizing differentiated responsibilities and the practical realities of different economies.
ISO's net zero standard: Five things you need to know
Q: What are your thoughts behind the targets and the pathway requirements that the ISO standard puts in and kind of how it approaches that?
The draft international standard draws on existing best practice but goes further, balancing robust climate science with feasibility across different economies and sectoral contexts, and it sets expectations around emissions reductions, activity targets, and carbon removal milestones to support Paris-aligned goals.
Built-in emissions: How to cut embodied carbon
Q: What are the most important steps in reducing embodied carbon for a rebuild?
Hannah and Monica stress reduce–reuse–recycle as foundational, advocate for design for disassembly, and highlight the value of engaging architects and builders early to align on low-embodied-carbon strategies.
Built-in emissions: How to cut embodied carbon
Q: Could you tell us about your motivation for the work that you do, and what's been a career highlight so far?
Monica explains her motivation to use her experience to benefit nature and people, with a standout achievement being the formation of Mecla, a cross-sector alliance to tackle embodied carbon.
