Avoiding Contrails on Night & Winter Flights Is Aviation’s Fastest Climate Win — New T&E Study
A new analysis by T&E shows that 25% of European aviation’s contrail-related global warming comes from night flights in autumn and winter, which make up just 10% of European air traffic. Contrail warming is highly seasonal and concentrated in time: in 2019, 75% of European contrail warming occurred between January to … [continued]

When Steel Outlives Strategy: The Climate Cost of Germany’s Hydrogen Pipeline
Germany’s 400 km hydrogen backbone segment is now pressurized, full of fossil hydrogen, and waiting. There are no meaningful suppliers connected to it and no contracted offtakers drawing molecules out. That fact alone makes it worth slowing down and doing the accounting carefully, because large infrastructure decisions do not become … [continued]

Xue: Don’t expect quick results from Mark Carney’s China visit
The state visit of Canadian Prime Minister Mark Carney is best understood as an ice-breaking moment to establish dialogue
Pricing Fertilizer Emissions Cuts Climate Pollution Without Making Food Expensive
Pricing fertilizer emissions sounds like a recipe for more expensive food, but when the numbers are worked carefully, it turns out to be a policy that cuts emissions sharply while barely moving grocery prices. The reason is simple and counterintuitive. Fertilizer is a large share of farm costs and an … [continued]

Pressurized Steel, Missing Demand: Germany’s Hydrogen Backbone In Energy Flows
The German hydrogen backbone without customers or suppliers—a pipeline from nowhere to nowhere—is real steel in the ground, pressurized and defended as inevitable, yet it is being built for an energy system that does not need it. That claim sounds provocative until the energy flows are laid out in full. … [continued]
