How does carbon pricing reduce emissions, and what are potential negative effects?

• A. It makes fossil fuels more expensive, encouraging low-carbon options; potential downsides include higher living costs and competitiveness concerns.
• B. It imposes no costs to consumers
• C. It only affects government revenue
• D. It does not affect emissions reductions

Answer: (A)

Pricing carbon creates a financial signal that makes emitting greenhouse gases costly. When fossil fuels carry a price, consumers and businesses shift toward cleaner energy, greater efficiency, and innovative low-carbon options, so overall emissions tend to fall as demand for high-emission fuels decreases and investments flow into cleaner technologies.

The approach can raise living costs because energy and goods produced with carbon-intensive fuels become more expensive. It can also affect competitiveness if domestic producers face higher costs than international rivals, sometimes prompting concerns about carbon leakage. Effective design—such as using revenue to offset high bills for households, reduce distortionary taxes, or invest in clean energy—helps mitigate these downsides while preserving the emission-reducing incentive.
