Climate and Political Economy

Climate and Political Economy
The climate crisis is the greatest challenge of the 21st century. The political economy of climate explains why it is so difficult to act despite scientific consensus, and what possible solutions exist.

Climate Economics
Externality. CO2 emissions are a classic negative externality. The costs are borne by everyone, the benefits—by the emitters. Without intervention—excessive emissions.

Global character. The atmosphere is a common good. Emissions in one country affect everyone. Global coordination is needed—and that is difficult.

Intergenerational dimension. Costs today, benefits—to future generations. What discount rate should be used? Stern vs. Nordhaus—different answers.

Political Barriers
Concentrated interests. The oil and gas industry has enormous lobbying influence. Millions of jobs depend on fossil fuels.

Diffuse benefits. The benefits of climate policy go to everyone, but in small amounts. Hard to organize support.

Geopolitical competition. Countries are afraid of losing competitiveness. Free rider problem—let others reduce.

Short-termism in politics. Electoral cycles—4–5 years. Climate consequences—decades. Misalignment of horizons.

Paths to Solutions
Carbon pricing. Carbon tax or cap-and-trade. Internalizing the externality. But politically difficult.

Regulation. Emission standards, bans on certain technologies. Less effective but politically simpler.

Green industrial policy. Subsidies for clean technologies, green investments. Creates new vested interests.

Just transition. Compensation and retraining for workers in carbon-intensive sectors. Reduces resistance.

International agreements. The Paris Agreement is a framework, but without enforcement. Mechanisms for compliance are needed.

Climate is a test for humanity. Are we capable of overcoming short horizons, national egoism, and group interests for the sake of a common future?
