Newsletter#133 Mapping Nature Risk Across the Supply Chain: Insights from Natcap’s assessment for a global food & beverage company
A global food and beverage company knew its supply chain depended on nature, but had never measured where that dependence became a financial risk. With Natcap, it traced the risk to its producers, deepening its understanding of its exposure as a buyer. The case study shows how supply-chain nature risk is located, why soil quality was the surprise, and why the hardest part was never the analysis.
Newsletter#132 Buildings Already Have the Technology. What They Lack Is Trustworthy Data.
Commercial real estate now has the economic, regulatory, and technological foundations to reduce energy waste. But according to Mike Zatz, former EPA ENERGY STAR leader and now at Measurabl, the biggest barriers are no longer technical, they're access to performance data, limited capacity to act on it, and weak incentives to share it.
Newsletter#127 TNFD Alternative Fuels Guidance: The Nature Test
TNFD's June 2026 sector guidance says cutting emissions is no longer enough. For alternative fuels, the next credibility test is nature, not carbon.
Newsletter#123 The Quiet Engine of Building Decarbonization
Heat pumps are becoming one of the most important tools for building decarbonization. As policies tighten and emissions reporting expands, the technology offers a proven pathway to reduce heating-related emissions, improve energy efficiency, and support long-term net-zero goals.
Newsletter#118 Measuring the State of Nature for TNFD: Inside the NPI pilot with NatureHelm and New Forests
NatureHelm and New Forests put the Nature Positive Initiative's State of Nature metrics to the test across selected assets in five countries. The pilot shows what satellite data can and can't measure at scale, why landscape connectivity became the metric stakeholders cared about most, and what it means for measuring nature across a 4.4-million-hectare portfolio and for TNFD disclosure.

This piece examines the rate battles, policy experiments, and corporate pledges shaping the answer, and why getting it right matters for energy affordability everywhere.
Newsletter#109 - The Methane Reckoning: Measured Reality Meets Reported Inventories
Satellite data have exposed a significant gap between reported and measured methane emissions, with some basins running several times higher than official inventories. At the same time, the EU Methane Regulation is turning import access into a compliance question. For sustainability professionals, the numbers underpinning disclosures and the rules governing gas markets are both shifting.
Newsletter#107 - Africa’s Forests Have Switched Sides. The Carbon Math Just Changed.
