Carbon pricing, border adjustment and renewable energy investment: a network approach (1 MB)

Abstract

An increase of €100 per tonne in the EU carbon price reduces the carbon footprint but lowers GDP due to higher energy costs and carbon leakage. Using a dynamic multi-sector, multi-country model augmented with an energy block that includes endogenous renewable energy investment, we analyze the macroeconomic and emissions effects of a carbon price. Investment in renewable energy mitigates electricity price increases in the medium term, leading to a smaller GDP loss (up to −0.4%) and a larger emissions reduction (24%) in the EU. Neglecting renewable energy investment overestimates the negative economic impact. We also find that a Carbon Border Adjustment Mechanism (CBAM) reduces carbon leakage but slightly hurts GDP and inflation as the competitive gain is offset by the higher costs of imported intermediate inputs.
