Why might wealthier countries invest more in green technologies than poorer countries?

• A. Lack of knowledge
• B. No interest in sustainability
• C. Economic constraints and affordability
• D. Universal access to technology

Answer: (C)

The idea being tested is how a country’s economic capacity and affordability shape its ability to invest in green technologies. Wealthier nations have more capital, larger tax bases, and better access to affordable financing, which makes the upfront costs of developing and deploying new green tech easier to bear. They can fund research and development, subsidize adoption, and spread large investments over time, attracting private investment and benefiting from economies of scale. Stable policies and financial markets in wealthier countries reduce risk, encouraging long-term climate investments that pay off later.

In poorer countries, budget constraints, higher relative costs, and competing needs for essential services mean even strong interest or knowledge about sustainability can be limited by what is affordable and financeable in the near term. That’s why economics—not a lack of knowledge or interest, and not universal access to technology—helps explain why wealthier countries invest more in green technologies.

Lack of knowledge, no interest in sustainability, or universal access to technology don’t account for the observed pattern, since capacity to finance and absorb upfront costs is the key driver.
