Leakage vs Competitiveness

Industry lobbies claim carbon pricing will devastate competitiveness and move production offshore. Environmental economists counter that leakage is modest and that free allocation generously overcompensates exposed industries. Both sides cite data. The truth depends on which industries, which timeframes, and which policy designs you examine.

The industry case. European cement, steel, and aluminum face carbon costs of 5-15% of production value. Competitors in Turkey, India, and China face zero. Even a 5% cost disadvantage in a globally traded commodity with thin margins can shift orders and investment. The European Aluminum Association reports production declining since 2008, with capacity shifting to Iceland (cheap geothermal), the Middle East (cheap gas), and China.

The economist case. Empirical studies of the EU ETS find leakage rates of 5-15%, far below what industry warned. Free allocation of allowances covered most costs. Many firms received more free allowances than their actual emissions, creating "windfall profits." The threat of leakage has been used to extract policy concessions (free allocation) that overcompensate exposed industries.

Where the argument actually lies. Short-term competitiveness effects are modest (free allocation works). Long-term investment effects are harder to measure (where does the next plant get built?). Both sides are partially right, but they are arguing about different timeframes and different margins.

How should policy handle this tension?

CBAM resolves it better than free allocation. Border adjustments maintain the carbon price signal (incentivizing decarbonization) while equalizing costs for imports. Free allocation weakens the signal. The EU is transitioning from free allocation to CBAM precisely because it addresses both leakage and competitiveness without sacrificing the emission reduction incentive.
