Transaction Costs and Institutional Fragmentation under Paris Agreement Article 6.2 A Comparative Institutional Analysis
This study argues that while plurilateral cooperation under Article 6.2 could reduce the transaction costs caused by fragmented bilateral agreements through standardized rules and infrastructure, it introduces new governance burdens, suggesting a bounded pilot approach is more prudent than immediate institutional expansion.

The world is trying to slow down climate change by cutting the greenhouse gases that warm the planet. Each country has made a promise, called a national plan, to reduce its own emissions. But sometimes, it is cheaper and easier for one country to help another country cut pollution than to do it alone. To make this work, the countries created a system where they can trade the results of these cuts. If a factory in one country stops polluting, that saved pollution becomes a credit that another country can buy to help meet its own goals. This system is designed to be flexible, letting countries work together in pairs to find the best deals. However, just because countries sign many agreements to trade these credits does not mean the trades actually happen. The paperwork, rules, and checks required for every single pair of countries can become so heavy and complicated that the system gets stuck.
A researcher named Yusik Won from the Korea Institute of Industrial Technology looked into why this is happening. The study focuses on a specific part of the global climate agreement known as Article 6.2, which allows countries to trade these pollution credits. The researcher wanted to understand why the number of signed deals has grown rapidly, yet the actual transfer of credits remains low. To find the answer, the study examined how three different countries—Switzerland, Japan, and Singapore—have tried to set up these trading systems. The researcher broke down the work involved in making a trade into four types of effort: finding a partner, writing the deal, checking that the work was done, and adjusting the plan when things change. These efforts are known as transaction costs, the hidden price of doing business that exists even before the money changes hands.
The study found that the current way of doing things, where countries sign separate deals with each other, creates a lot of repeated work. Every time a buyer country wants to trade with a new partner, they have to negotiate a fresh set of rules, create new paperwork, and build a new way to check the results. Even if a country has done this before, they often cannot simply reuse the old rules because the new partner has different laws or needs. This means the countries end up paying the same price over and over again just to set up the system, rather than spending their energy on the actual pollution cuts. The researcher looked at how Switzerland, Japan, and Singapore tried to fix this. Switzerland uses a private foundation to find projects and buy credits, which helps them organize their spending, but they still have to negotiate a new deal for every country they work with. Japan uses a long-standing system with its partners that has standard rules, which saves some time, but they still need a separate committee and agreement for each country. Singapore is trying to use existing global standards for credits to skip some of the setup work, but this approach has not yet been tested with a real trade.
The core problem identified is that while these countries have found ways to make their own systems slightly more efficient, none of them have solved the bigger issue of connecting with many different partners easily. The rules for one pair of countries do not fit the next pair. This creates a fragmented system where the credits are hard to move around. The researcher suggests that instead of trying to build a single, massive global rulebook right away, a smaller group of countries with similar goals should try a different approach. They could agree on a shared set of basic rules and a common way to check the work, while still keeping their own authority to decide which projects to support. This would allow them to trade more easily without having to start from scratch every time. The study proposes that a small group of willing countries should test this idea first. They would try to use these shared rules for a specific type of project to see if it actually saves time and effort compared to their usual method.
The research does not claim that this new way is a guaranteed success or that it has already been proven to work. It is a suggestion based on comparing how the current systems operate. The study points out that creating a shared group of rules would also bring new costs, such as the time needed to agree on those rules and the effort to keep the group running. Therefore, the best path forward is not to force everyone to change immediately, but to run a careful, limited test. A small group of countries could try this new model to see if it truly reduces the heavy burden of paperwork and negotiation. If the test shows that it works, it could eventually help more countries trade their pollution credits efficiently, allowing them to focus their resources on actually cleaning the air rather than filling out forms. Until such a test is done, the high cost of setting up each new deal remains a major barrier to getting the global climate trading system moving.
