Manual de Medio Ambiente y Comercio

The document examines the complex interactions between the multilateral trading system, primarily the World Trade Organization (WTO), and international environmental governance, including Multilateral Environmental Agreements (MEAs). It analyzes how trade liberalization can both benefit and harm the environment through scale, structural, and product effects. The text details the legal tensions surrounding Process and Production Methods (PPMs), intellectual property rights (TRIPS), and agricultural subsidies, while advocating for the 'mutual support' of trade and environmental goals. It also explores the role of regional trade agreements as laboratories for innovative environmental governance and emphasizes the importance of capacity building and environmental impact assessments in trade policy.

• Trade liberalization is not inherently good or bad for the environment; its impact depends on whether environmental and trade objectives are complementary and mutually supportive through appropriate national and international policies.
• Trade affects the environment through four primary channels: product effects (diffusion of green technology or movement of hazardous waste), scale effects (increased economic activity leading to higher resource use), structural effects (changes in a country's economic composition), and direct effects (pollution from transport and invasive species).
• The WTO's non-discrimination principle, specifically 'national treatment' and 'most-favored-nation' status, applies to 'like products.' A central conflict arises when countries attempt to discriminate against products based on non-product related Process and Production Methods (PPMs).
• The WTO Appellate Body established a precedent in the US-Shrimp case, ruling that trade measures based on PPMs can be justified under GATT Article XX(g) for the conservation of exhaustible natural resources, provided they are not applied in an arbitrary or unjustifiably discriminatory manner.
• Multilateral Environmental Agreements (MEAs) often use trade-related provisions to ensure compliance, such as the Montreal Protocol's ban on trade in ozone-depleting substances with non-parties, which incentivizes global participation.
• The TRIPS Agreement can conflict with sustainable development by favoring formal innovation (patents) over informal innovation (traditional farmer practices), potentially leading to a loss of agricultural biodiversity.
• Perverse subsidies, estimated globally between $500 billion and $1.5 trillion annually, distort prices and encourage unsustainable practices, such as overfishing in the fisheries sector.
• Agricultural subsidies in developed countries, particularly those linked to production (Amber Box), often lead to overproduction and the excessive use of chemical inputs, while depressing international prices for producers in developing nations.
• Bilateral Investment Treaties (BITs) can undermine environmental governance by allowing investors to challenge public interest regulations (such as waste management or pollutant control) as forms of 'indirect expropriation' through investor-state dispute settlement.
• The Doha Development Agenda includes specific commitments to reduce barriers to 'environmental goods and services,' though defining these terms remains a significant challenge due to 'dual-use' products and disagreements over PPM-based distinctions.
