Should Climate Policy Be Global or National?

Climate change is one single phenomenon within the atmosphere; however, it is controlled by fragmented political systems. This leads to a structural contradiction, whereby the planet operates as one climate, while the policy responses are separated into conflicting national interests. This explains why there is an ambitious policy approach in place, but implementation is lacking.

The Global Governance Framework

The international policy on climate change revolves around cooperation. For example, the Paris Agreement tries to unite nations around shared temperature levels and reduction in emissions. The reasoning behind such attempts is quite simple: because greenhouse gases spread across the globe, no country can solve the problem by itself. In addition, the global response framework ensures that “carbon leakage” will not occur, meaning that emissions will not simply move to another location. Finally, all participating countries use the same criteria for measurement and reporting purposes.

At the same time, global governance is based on a soft-law approach. There are very few binding obligations for participating countries, and the enforcement of existing ones is limited. Thus, even though international policies outline goals and plans, the actual enforcement of decisions may be lacking.

A notable example of this limitation came in 2017, when the United States withdrew from the Paris Agreement under President Donald Trump, who said the deal was harming the national economy and industrial competitiveness. The Paris Agreement was based largely on voluntary rather than binding commitments, so few mechanisms existed to stop the withdrawal. But the United States rejoined the deal in 2021 under President Joe Biden, showing how domestic political leadership can change climate commitments. This case demonstrates the fact that climate change is a global problem; however, international agreements are still reliant on national governments to implement and enforce them.

The National Policy Reality

National policy on climate is where it all happens. Energy transitions, industrial rules, electrification of transport, and land-use decisions are managed at the domestic level. This means the country can formulate policies relevant to its economy and developmental needs. Thus, any expansion of renewables, subsidy reforms, and emissions standards must be implemented under national law to work effectively.

However, a purely national perspective results in fragmentation. The distribution of climate effects ignores the extent of responsibility for or the location of the emitter. Those countries that emitted less in the past are more vulnerable to changes, whereas wealthier nations have better opportunities to adapt to them. Without global collaboration, climate policy might exacerbate social injustice.

Conclusion

There is no clear-cut solution to the issue. Climate governance consists of two layers of policy-making:

• Global Guidelines: Agreed-upon metrics, principles of equity, and international targets.
• National Policy: Domestic legislation that translates international goals into practical execution.

Both are equally important to the effectiveness of climate policy. The core paradox of climate change is that, by its very nature, global problems require national solutions. It is impossible to choose one layer of the policy system over the other.
