Introduction
This chapter examines the multi-layered legal architecture that governs green business activities in Rwanda and underpins the concept of environmental profit maximization. It proceeds across three interconnected levels: international law, regional law within the East African Community (EAC), and national law in Rwanda. Together, these frameworks create the normative environment in which businesses are both incentivized and compelled to integrate environmental sustainability into their profit-seeking strategies.
The United Nations Framework Convention on Climate Change (UNFCCC) and the Paris Agreement
The Paris Agreement (2015) constitutes the most consequential international instrument shaping green business obligations globally. Adopted under the UNFCCC, it commits State Parties, including Rwanda to limit global average temperature increases to well below 2°C above pre-industrial levels, with efforts to restrict warming to 1.5°C[1]. Critically for business actors, Article 2(1)(c) explicitly calls for making financial flows “consistent with a pathway towards low greenhouse gas emissions and climate-resilient development,” embedding green investment as a treaty obligation.[2]
Rwanda submitted its first Nationally Determined Contribution (NDC) in 2016 and updated it in 2020, committing to reduce greenhouse gas (GHG) emissions by 38% relative to a business-as-usual scenario by 2030.[3]
The Convention on Biological Diversity (CBD) and the Kunming-Montreal Framework
The Convention on Biological Diversity (1992) and its Kunming-Montreal Global Biodiversity Framework (2022) impose obligations on parties to integrate biodiversity considerations into business and financial decision-making. Target 15 of the Kunming-Montreal Framework specifically requires large businesses and financial institutions to assess and disclose biodiversity-related risks and impacts, thereby institutionalizing what scholars describe as “biodiversity profit maximization,” the alignment of corporate strategies with the preservation and sustainable use of natural capital.
The UN Guiding Principles on Business and Human Rights and the SDGs
The UN Guiding Principles on Business and Human Rights (UNGPs, 2011) establish the corporate responsibility to respect environmental rights as an emerging dimension of the business and human rights nexus. Principle 13 requires businesses to avoid causing or contributing to adverse human rights impacts through their activities a category that increasingly encompasses environmental harm, given the recognition of the right to a clean, healthy and sustainable environment by the UN General Assembly in Resolution 76/300 (2022).[4]
The 2030 Agenda for Sustainable Development and its 17 Sustainable Development Goals (SDGs) further articulate a global normative expectation that business activity must generate social and environmental value alongside economic returns[5].
The EAC Treaty and Environmental Commitments
The Treaty for the Establishment of the East African Community (1999, as amended) provides the foundational regional framework for environmental governance. Article 111 specifically obliges Partner States to “take joint measures to promote the protection and conservation of the natural resources and environment of the Community and to take such other measures as may be necessary to that effect.” This provision has been interpreted as supporting harmonized green business standards across the EAC bloc, enabling Rwanda to benchmark its regulatory framework against regional best practices.[6]
The EAC Climate Change Policy and Green Growth Strategy
The EAC Climate Change Policy (2011) and the EAC Green Growth and Climate Resilience Strategy provide the regional architecture for mainstreaming climate considerations into economic activities, including trade and investment.[7]
National Legal Framework in Rwanda
The Constitution of the Republic of Rwanda provides the supreme legal foundation for environmental governance. Article 22 enshrines every citizen’s right to a healthy and satisfying environment and places a corresponding duty on every person and the State to protect, safeguard, and promote the environment. This constitutional provision elevates environmental protection.[8]
The Organic Law N°48/2018 on the Environment
Law of the environment in Rwanda constitutes the primary legislative instrument for environmental management. The law establishes the principle of sustainable development as the overarching framework for all economic activity, mandating that development meets the needs of the present without compromising the ability of future generations to meet their own needs.[9]
Investment Law and Green Business Incentives
The Law No. 006/2021 of 05/02/2021 relating to investment promotion and facilitation in Rwanda explicitly provides preferential treatment for investments that contribute to environmental sustainability and green growth[10]. The Rwanda Development Board (RDB), operating under this framework, grants fiscal incentives including tax holidays, reduced corporate income tax rates, and preferential customs treatment to businesses classified as green investments..[11]
Conclusion
The legal framework governing green business in Rwanda and environmental profit maximization is both robust and multi-layered, Rwanda’s constitutional provisions, environmental legislation, investment law, and green growth strategy create a coherent and increasingly enforceable architecture for green business. The cumulative effect of these instruments is to constitute environmental profit maximization not as an optional corporate strategy, but as an emerging legal obligation one that businesses operating in Rwanda are increasingly required, as well as incentivized, to pursue.
