Distributional Consequences of Becoming Climate-Neutral

The EU has embarked on an ambitious path towards climate neutrality.

The EU has embarked on an ambitious path towards climate neutrality. How difficult will this transition be for the population as a whole and for different subsets of consumers? This paper investigates this question using a dynamic general-equilibrium model that captures a key feature of energy consumption: the relative energy content of one’s consumption basket falls significantly as a function of one’s relative income. Thus, low-income consumers are expected to be hit harder by the higher energy prices that we anticipate over the next few decades. In the model, energy—a complementary input to capital and labour—can be produced either using fossil fuel or a ‘green’ technology. We represent the EU policy in terms of a tax on fossil fuel and show that the European Commission’s Fit-for-55 package implies a 106.4% tax on the fossil-based technology. The output losses from this tax are substantial, and GDP is 6.3% lower in the new steady state. The burden falls primarily on the lowest-income agent, who represents the first income quintile and is 47% more worse off than the highest-income agent, representing the fifth quintile. The output losses can almost be cut in half if the economy achieves a simultaneous increase in energy efficiency, as outlined in the Fit-for-55 package.
