How NPR-PPMs under the Technical Barriers to Trade impact the Global South

NPR-PPMs: When Process Matters More Than Product

What are NPR-PPMs?

In global trade, the products we buy and sell are not just defined by their characteristics but also by how they are produced. Under the World Trade Organization (WTO) framework, member states regulate these through laws called technical regulations. These rules may cover aspects like labeling, packaging, and product safety.

But there’s a twist. Some production methods do not change the product itself but still matter. These are called Non-Product Related Process and Production Methods (NPR-PPMs).

NPR-PPMs Explained

Production methods can be divided into two categories:

  1. Product-related PPMs – These affect the actual characteristics of the product. Example: blending ethanol with gasoline changes the fuel’s properties.

  2. Non-Product Related PPMs (NPR-PPMs) – These do not change the product itself. Example: whether sugarcane for ethanol was grown by cutting down forests or not.

So, NPR-PPMs are about the process, not the product. This makes them tricky in trade, because two products may look identical, but one may be seen as more sustainable than the other.

NPR-PPMs in WTO Trade Rules

Here’s the key issue: WTO rules focus on products, not processes.
If a country imposes tariffs based only on NPR-PPMs (like taxing ethanol made with deforestation differently than ethanol made without deforestation), it could violate the WTO’s principles of Most-Favoured Nation (MFN) and National Treatment (NT).

However, labeling rules have become a workaround. For example, a country may require that all imported ethanol must carry a “deforestation-free” label. This doesn’t directly discriminate by country, but it can still hit some economies harder than others.

Why NPR-PPMs Are Rising in Importance

NPR-PPMs are at the center of debates on:

  • Environmental protection (reducing deforestation and carbon footprints)

  • Human rights (ensuring fair labor conditions and eliminating child labor)

These measures are sometimes called green trade measures, since they tie trade rules to sustainability goals

Case Study: EU’s Deforestation Regulation and Ethiopian Coffee

The European Union’s deforestation regulation is a prime example of NPR-PPMs in action. It requires that coffee and other imports be certified as “deforestation-free.”

  • Impact on Ethiopia:

    • Coffee makes up 30–35% of Ethiopia’s exports.

    • Around 25% of the population depends on coffee.

    • Most farmers are smallholders with limited resources.

To comply with EU rules, they must prove their coffee is deforestation-free. But documenting land records and supply chains is costly. Many small farmers cannot afford this.

As a result:

  • Ethiopian coffee risks losing competitiveness.

  • EU buyers are shifting to other suppliers.

  • Farmers may lose livelihoods.

This raises the question: are such rules about climate action, or hidden trade protectionism?

Problems with NPR-PPM-based Measures

  1. Broad definitions – For example, the EU counts even legal deforestation (government-approved land clearing) as a violation.

  2. Unfair burden on the Global South – Agrarian economies rely on expanding farmland for exports. Restricting them harms their industrialization process.

  3. Dependency creation – To comply, these countries depend on costly technology and finance from developed nations, keeping them in debt.

Green Trade Measures and Dependency

This phenomenon is often called “green squeezing.” On the surface, it helps fight climate change. But in practice, it:

  • Raises production costs in developing countries.

  • Increases unemployment and debt.

  • Limits exports and stunts industrialization.

Dependency theorists argue this keeps the Global South tied to the Global North, reinforcing unequal trade relationships.

Balancing Environment and Livelihood

No one denies the importance of protecting the environment. But rules must also:

  • Consider the economic realities of the Global South.

  • Provide time and support for gradual transition.

  • Focus on capacity building instead of trade restrictions.

Otherwise, these measures risk becoming protectionist tools that block fair global growth.

Conclusion

NPR-PPMs highlight the tension between sustainability goals and fair trade practices. While they can support climate action, poorly designed measures—like the EU’s deforestation regulation—can harm developing economies.

For global trade to be both green and fair, the WTO must find ways to balance environmental objectives with the need for equitable development. Otherwise, the Global South may turn inward, forming trade blocs and eroding the principles of global free trade.
