LEED v5, Embodied Carbon, and Real Emissions Cuts Artwork

Climate Confident - Practical Climate Solutions That Cut Emissions

Climate Confident is for business leaders, climate professionals and policymakers who need to understand what is actually cutting emissions—and what it takes to make those solutions work at scale.

Each Wednesday, I speak with the executives, engineers, scientists, founders and policymakers turning climate ambition into measurable progress. Together, we examine the technologies, business models, policies and implementation strategies reshaping energy, transport, industry, supply chains, food and finance.

These are not conversations about distant targets, vague pledges or greenwash. They are candid discussions about what is working, what is failing, where the real bottlenecks lie, and how leaders can make better decisions about decarbonisation, resilience, investment and risk.

You will hear:

Proven approaches to reducing emissions
Hard-earned lessons from real-world implementation
Analysis of the markets, technologies and policies driving the transition
Honest examination of costs, trade-offs, setbacks and unintended consequences
Practical ideas for turning climate commitments into action

New episodes are published every Wednesday at 7am CET. Subscribers also receive bonus episodes featuring highlights, analysis and emerging themes from across the series.

Follow Climate Confident for practical climate solutions, informed debate and the insights you need to turn ambition into measurable progress.

What if the biggest barrier to decarbonising buildings isn’t technology, cost, or ambition - but sheer complexity?

The built environment produces nearly 40% of global emissions, yet we still make low-carbon construction harder than it needs to be.

In this episode, I’m joined by Tommy Linstroth, founder of Green Badger, to unpack why construction remains one of the most overlooked climate battlegrounds, and why that’s a mistake. We dig into LEED v5, embodied carbon, and the growing gap between climate ambition and what actually happens on building sites. The stakes are huge: buildings lock in emissions for decades, sometimes centuries.

You’ll hear why builders aren’t resisting sustainability, they’re drowning in shifting standards, paperwork, and fragmented data. We explore how LEED has evolved, why carbon now sits at the centre of green building standards, and how decisions made at the design stage quietly determine emissions for the next 100 years. Tommy also explains why third-party verification matters, how “build to code” often means “barely legal”, and why retrofitting existing buildings may be the hardest climate challenge nobody likes talking about.

We also dig into where genuine momentum is emerging - from falling renewable costs to better data and smarter software, and how climate tech, including AI, could finally make the low-carbon choice the easy choice. If net zero, emissions reduction, and the energy transition are serious goals, then construction can’t stay a side quest.

🎙️ Listen now to hear how Tommy Linstroth and Green Badger are helping turn sustainable building from a compliance headache into real-world climate action.

Kismet: Golf tournaments can book venues out to 2049, yet many organisations still can’t map a credible path to 2040 climate targets. The problem isn’t foresight, it’s priorities.
