Which historical example illustrates the risk of sustainability measures ignoring wealth inequality?

• A. Paris Agreement
• B. EU ETS
• C. Green Deal
• D. The Yellow Vests Riots demonstrate how sustainability measures can fail if wealth inequality is ignored

Answer: (D)

Policies that push sustainability forward must consider how the costs and benefits are distributed across society. When environmental measures raise living costs or appear to hit lower-income groups harder without protections or benefits for them, public support can collapse and the policies can falter.

The Yellow Vests in France provide a clear historical example of this risk. What began as protests against a fuel tax tied to climate action quickly connected to broader concerns about cost of living and perceived inequalities in how the transition would affect ordinary people. The movement showed that if wealth gaps and the financial strain on lower-income households aren’t addressed, people may push back against sustainability measures, undermining both social peace and environmental goals. This highlights the need for equity-focused design—like revenue recycling, targeted supports for vulnerable households, and planned transitions for workers—so climate action is affordable and fair for everyone.

The other options point to important climate-policy tools or frameworks, but they don’t illustrate a direct, historical instance of social backlash driven by wealth inequality in the same way.
