Lucas and Luna focus on the Port of Los Angeles and Shanghai's new green shipping lane, which aims to cut emissions by 30% by 2030. They discuss the specific incentives, like reduced port fees and priority berthing, that make this work. The conversation also covers the economics behind the shift, includin...

The 45Q tax credit for carbon capture has been around for years, but the 2025 Inflation Reduction Act expansions turned it into a full-blown investment gold rush. Lucas and Luna dig into the numbers: how the credit per ton jumped, which industries are piling in — ethanol, direct air capture, cement — and whether the economics actually work yet. With a specific look at the 45Q market in mid-2026, t...

Episode 93 of Climate Economics digs into the surprising economics of green data centers powering the AI boom. Lucas and Luna explore how a single data center in Finland — running on 100% hydroelectricity — cut its carbon footprint by 80% while lowering energy costs by 40% compared to a traditional facility. They break down the numbers behind liquid cooling, waste heat recycling, and the race for...

In episode 92 of Climate Economics, Lucas and Luna explore the rise of green mortgages — loans that offer better rates for energy-efficient homes. The episode drills into a specific case: the UK's Green Homes Grant scheme and how it has evolved into a market-driven product in 2026. They discuss how lenders like Nationwide and Barclays are now offering rate discounts of up to 50 basis points for ho...

Episode 91 of Climate Economics with Fexingo dives into the surprising economics of green tariffs—special electricity rates that let big industrial buyers source 100% renewable energy without building their own solar farms. Lucas and Luna break down how companies like Google and Microsoft are using these tariffs to lock in stable power prices while cutting emissions, and why utilities are reluctan...

Episode 90 of Climate Economics with Fexingo: Lucas and Luna explore how green bonds are quietly replacing traditional municipal bonds as the go-to funding tool for infrastructure projects. Focusing on the US municipal market, they break down the $500 billion muni bond universe and how green-labeled bonds now account for 12% of new issuance, up from just 2% five years ago. They discuss the specifi...

Lucas and Luna dive into how a single Roman concrete recipe discovered at a 2024 MIT dig is now being scaled by a Swiss startup to cut cement emissions by 60 percent. They unpack the chemistry—volcanic ash vs. Portland cement—and the economics: why this ancient tech costs 20 percent less per ton than carbon capture on traditional concrete. A deep look at how a 2,000-year-old fix is beating modern...

Episode 88 of Climate Economics with Fexingo: Lucas and Luna unpack the rise of green tariffs—specialized electricity rate structures that let large industrial buyers source 100% renewable power through utility grids.
