Green at the Margins? Reframing Environmental Protection in Africa’s Continental Integration

As preferential trade agreements continue to proliferate and global trade volumes expand, new challenges have emerged alongside their anticipated economic benefits: most notably the environmental consequences of intensified trade and production. Despite the scale of this transformation, the environmental impacts of trade liberalization remain relatively underexplored in both academic and policy debates. Only a limited number of studies have systematically assessed how rising trade flows, industrial activity, and expanded transport connectivity affect natural ecosystems, resource use, and carbon emissions.

Seychelles provides a particularly instructive illustration of these dynamics. As a small island economy whose development model relies heavily on environmental assets (especially tourism), the country has explicitly incorporated environmental considerations into its African Continental Free Trade Area (AfCFTA) implementation strategy. The strategy acknowledges that AfCFTA-induced increases in production, industrialization, and transport links with other African countries are likely to intensify pressure on natural resources. Expanded trade is expected to raise CO₂ emissions through higher levels of maritime, air, and land transport, as well as through increased fossil fuel consumption associated with industrial growth. Greater cross-border movement of goods and people by sea, air, and road is therefore likely to amplify environmental stress on the island’s fragile ecosystems.

In response to these risks, the Seychelles strategy emphasizes the need to balance the economic opportunities created by the AfCFTA with environmental sustainability. It calls for a shift toward green industrialization through a comprehensive policy approach that embeds environmental objectives into industrial development. Key priorities include the efficient use of natural resources such as water and energy, the adoption of circular economy principles to reduce waste and improve resource efficiency, and the promotion of clean technologies in sectors such as manufacturing, transport, and construction. The strategy also underscores the importance of investment in research and development and the facilitation of technology transfer from other AfCFTA State Parties to stimulate innovation in green technologies.
More broadly, environmental protection is now widely recognized as an integral component of socio-economic development. Yet, only a limited number of international trade agreements place environmental considerations at the core of their legal architecture.

Data from UN/ESCAP’s Legal TINA (Trade Intelligence & Negotiation Adviser) database—which catalogues more than 700 treaties, conventions and agreements worldwide—indicate that only 187 contain a chapter or specific provision dedicated to environmental issues. Even among these, environmental commitments are often confined to preambular language or general cooperation clauses, with few agreements establishing concrete or enforceable environmental obligations.

Within Africa, the integration of environmental considerations into regional trade frameworks remains uneven and is often expressed in general principles rather than through specific operational and enforceable commitments. At the regional level, only a limited number of Regional Economic Communities (RECs) contain explicit environmental mandates in their founding instruments. The Economic and Monetary Community of Central Africa (CEMAC), for example, includes environmental provisions in Articles 39 to 41 of its establishing Treaty. These provisions mandate the Council of Ministers to adopt regulations and recommendations aimed at coordinating the environmental protection policies of member States, while implementation powers are entrusted to the Executive Secretariat.

Similarly, the East African Community (EAC) Treaty identifies environmental protection as one of the Community’s objectives. Specifically, Article 5(c) refers to the promotion of the sustainable use of natural resources and the adoption of measures to effectively protect the natural environment of Partner States. In addition, Articles 111 to 114 establish specific obligations relating to environmental and natural resource management. Comparable provisions are also found in the ECOWAS and COMESA Treaties. Furthermore, the EAC Protocol on the Establishment of the Common Market requires Partner States to apply sound environmental and natural resource management principles in support of the functioning of the Common Market (Article 40).

At the continental level, environmental protection occupies a relatively limited and fragmented position within the AfCFTA framework. General references appear in the Agreement’s preamble and in Article 3(e), which identifies inclusive and sustainable socio-economic development as one of the AfCFTA’s objectives. More substantially, Article 26 of the Protocol on Trade in Goods establishes general exceptions allowing State Parties to adopt measures necessary to protect human, animal, or plant life or health, and to conserve exhaustible natural resources, provided such measures are not applied in a discriminatory or arbitrary manner. This provision basically frames environmental protection as an exception to trade obligations rather than as a guiding principle of continental integration.

More comprehensive environmental protection mechanisms are found in the AfCFTA Protocol on Investment. This Protocol explicitly recognizes the right of State Parties to regulate in pursuit of sustainable development objectives and to protect legitimate public welfare interests, including environmental protection and the conservation of living and non-living exhaustible natural resources. It requires investors to conduct environmental and social impact assessments prior to initiating investment projects and encourages State Parties to promote investments that contribute to climate change mitigation and adaptation. In this respect, the Protocol offers a potential entry point for advancing green investments, developing regional green investment standards, and fostering cooperation in sectors such as renewable energy, low-carbon technologies, and climate-resilient infrastructure.

Nevertheless, within the AfCFTA framework, environmental protection remains largely subordinate to the primary objective of trade liberalization. This limited and fragmented treatment has increasingly prompted debate on the need for a dedicated Environmental Protocol, particularly in light of Article 8.3 of the AfCFTA Agreement, which explicitly allows for the adoption of additional instruments consistent with the Agreement’s objectives (which, as noted above, include sustainable socio-economic development, of which environmental protection is an essential component). The current absence of precise, binding, and enforceable environmental obligations is especially concerning given that Africa is among the regions most exposed to the adverse effects of climate change, despite contributing only marginally to global greenhouse gas emissions.

Reframing environmental protection as an integral component of continental integration (rather than as a constraint on trade) could transform this apparent weakness into a source of comparative and competitive advantage. By embedding environmental sustainability more firmly within the AfCFTA architecture, Africa could leverage its trade regime to attract green investment, foster innovation in sustainable technologies, and promote climate-resilient industrialization. The AfCFTA already contains the legal basis and institutional flexibility to support such a shift. What remains is a strategic choice: whether to allow environmental considerations to remain peripheral, or to elevate them to a structural pillar of Africa’s integration project, aligning trade liberalization with long-term development, resilience, and global leadership in sustainable economic governance.
