  1. Cutting import tariffs causes domestic firms to cut their greenhouse gas emissions, with affected companies showing about 20–25% lower scope 1 intensity and 5–10% lower scope 2 in the year after a tariff reduction.
  2. The reason is competition: cheaper imports push firms to innovate, switch to greener products that fetch a premium, or invest in modern, less emissions‑intensive machinery to protect margins.
  3. Broadly protecting home markets with higher tariffs can weaken competitive pressure to decarbonize, though targeted border measures aimed at preventing regulatory arbitrage can still be useful.

Europe's Fast-Closing Carbon Window

  1. Europe is creating a unique carbon market that will charge importers for the carbon in goods like cement and steel. This could raise around €100 billion in its first years, encouraging other countries to reduce emissions.
  2. Carbon removal technologies can turn captured CO₂ into valuable products like concrete, fuels, and chemicals. This means companies can make money while helping the environment, which is vital for creating new industries.
  3. To succeed, European firms need to focus on scaling up their operations and capitalizing on new technologies. It's not enough to follow market rules; they need to invest in building strong companies that can compete globally.
