This chart explains the different ways green fiscal policies (like carbon taxes, green subsidies, etc.) can fail after they are launched, and how those failures can be avoided.
The process starts with the launch of a green fiscal policy.
The first question is: Are there design problems?
If yes, it leads to poor policy design. Poor design shows up in two major ways:
Pricing issues - the cost is too high for the public, there’s no gradual ramp-up, or pricing signals are unclear.
Revenue recycling failures - the benefits are not visible to the public, there’s unequal distribution of the revenue, or there’s no compensation for households.
These issues often lead to public backlash, such as protests.
If poor design is not the issue, the next question is: Are there implementation issues?
If yes, the most common problem is political resistance. This can come from:
Weak coalition building - for example, industry opposition, no stakeholder buy-in, or political divides.
Poor timing - such as trying to roll out policy during a recession, election, or crisis.
Political resistance often leads to policy reversal, where a new government scraps the plan, or policy weakening, where the policy is watered down, delayed, or made more complex. These outcomes lead to an ineffective policy, which means, it misses its emissions goals, loses credibility, and wastes resources.
If there are no implementation issues, the next question is: Are there external shocks?
External shocks could be energy price spikes, economic downturns, or geopolitical events. If these happen, governments may respond by:
Temporarily suspending the policy (for example, pausing carbon pricing),
Or introducing emergency measures.
These responses may also weaken the policy and reduce its impact.
On the other hand, if there are no design problems, no implementation issues, and no major external shocks, then the policy can succeed.
To prevent these failures, there are three key strategies:
Smart design - set moderate prices, redistribute revenue fairly, and make the benefits clear.
Early engagement - bring in broad coalitions early, deal with concerns openly, and maintain ongoing dialogue.
Adaptive implementation - allow for adjustments, plan for crises, and conduct regular reviews.
In short, most policy failures happen because of poor design or lack of stakeholder support, not because the ideas themselves are flawed. Designing policies well, planning for challenges, and involving the right people early can make green fiscal policies much more likely to succeed.
