Adapting Economic Policy for the Climate Emergency: Insights from Heather Stewart

The recent heatwave in the UK serves as a stark reminder of the climate crisis affecting our daily lives. While countries in the global south often bear the brunt of these extreme weather patterns, the impacts are felt worldwide.

Take chocolate, for instance. The price in the UK surged by 18% last month, hitting a record high. The reason? Weather-related failures in cocoa crops in West Africa. This is just one example of how our changing climate is disrupting food production.

In the U.S., spending on recovery from climate disasters—like wildfires and floods—reached a staggering $1 trillion last year, according to Bloomberg Intelligence. Companies that focus on repair, such as DIY chains, are benefiting, but it raises questions about the diversion of resources from other important areas. This isn’t just an economic issue; it’s a widespread financial shift, with significant costs now earmarked for recovery rather than growth.

A recent study by U.S. researchers highlights another troubling aspect: wildfires can reduce earnings for workers by up to 2%. That translates to around $125 billion lost in total earnings across the country, with older employees bearing the brunt of the impact. Smoke travels far beyond the flames, proving how health crises tied to climate change create economic challenges.

In wealthy nations, the climate crisis continues to siphon financial resources, resulting in repeated cost shocks. Christine Lagarde, the European Central Bank chief, referred to this as an “age of shifts and breaks.”

A recent analysis by Isabella Weber and her colleagues examined 100,000 earnings calls from U.S. companies and found an interesting trend. During economic shocks, businesses often raise prices, seeing these increases as an opportunity for higher profit margins. Instead of absorbing costs, they perceive them as a chance to boost their bottom line. This phenomenon can complicate inflation management, particularly during crises when prices are already on the rise.

Weber and her team argue that this “sellers’ inflation” isn’t just about rising costs imposed by worker demands. Instead, it stems from strategic behavior by companies.

As climate change disrupts food production, policymakers face mounting challenges. The typical response, raising interest rates, is often too blunt for this type of inflation. Instead, there’s a call for innovative approaches. Barmes and Pereira da Silva from the LSE propose “adaptive inflation targeting.” Their idea suggests being more tolerant of short-term inflation spikes due to climate impacts. They argue that amid repeated cost shocks, allowing central banks to temporarily target higher inflation could keep government borrowing costs down and support necessary green investments.

As we experience unusual heat levels and extreme weather, it’s clear that not just our infrastructure, but also our economic policies need to change. The UK and other nations must adapt to a future where climate challenges are a constant reality, shaping not only our environment but our economies, too.
