Environment & Climate Change

Stephen Walt provides A realist POV on the war in Ukraine, competition with China, COVID, and more in the second part of an interview with Foreign Policy Editor-in-Chief Ravi Agrawal.

Maintaining bitcoin and other cryptocurrencies causes about 0.3 percent of global CO₂ emissions. That may not sound like a lot, but it’s more than the emissions of Switzerland, Croatia, and Norway combined. As many cryptocurrencies crash and the FTX bankruptcy moves into the litigation stage, regulators are likely to scrutinize the crypto world more than ever before. This presents a perfect opportunity to curb their environmental damage.

The good news is that cryptocurrencies don’t have to be carbon intensive. In fact, some have near-zero emissions. To encourage polluting currencies to reduce their carbon footprint, we need to force buyers to pay for their environmental harms through taxes.

Stephen Walt looks back at the Trump administration as four years of big ambitions, a handful of successes—and many more failures. He concludes that it was more than a missed opportunity because Trump's blunders have left the United States in much worse shape than when he took office.

Stephen Walt writes that the United States' unusual historical experience, geographic isolation, large domestic market, and general ignorance have weakened its ability to make viable foreign-policy strategies.
