Environmental Law in Nigeria

Introduction

Environmental law in Nigeria has evolved significantly in response to the environmental challenges posed by rapid urbanization, industrial development, and particularly oil and gas extraction in the Niger Delta. The legal framework encompasses constitutional provisions, statutes, regulations, and international treaties. The National Environmental Standards and Regulations Enforcement Agency (NESREA) serves as the primary environmental regulator, while the National Oil Spill Detection and Response Agency (NOSDRA) addresses oil pollution specifically. The Petroleum Industry Act (PIA) 2021 introduced significant environmental reforms for the petroleum sector.

Constitutional Foundation

The Constitution of the Federal Republic of Nigeria 1999 provides indirect constitutional protection for the environment through the Fundamental Objectives and Directive Principles of State Policy. Section 20 of the Constitution provides that the State shall protect and improve the environment and safeguard the water, air, and land of Nigeria. While these provisions are non-justiciable under section 6(6)(c), courts have referred to them in interpreting environmental legislation. Chapter IV fundamental rights, particularly the right to life (section 33) and the right to dignity (section 34), have been invoked in environmental litigation, most notably in Gbenrre v Shell Petroleum Development Company (2005) AHRLR 151, where the court recognized the right to a clean environment as inherent in the right to life.

NESREA Act 2007

The National Environmental Standards and Regulations Enforcement Agency (NESREA) Act 2007 establishes NESREA as the primary environmental regulatory authority. The Agency is responsible for enforcing environmental standards, regulations, and guidelines. NESREA has issued numerous regulations covering sectors including air quality, water quality, waste management, noise control, and chemical safety. The Agency conducts environmental audits, monitors compliance, and prosecutes violators. Section 20 empowers NESREA to impose administrative penalties and seek court orders for compliance.

Environmental Impact Assessment

The Environmental Impact Assessment (EIA) Act Cap E12, LFN 2004, requires mandatory environmental impact assessment for specified projects. Section 2 provides that no project likely to have significant environmental impact shall be commenced without prior EIA approval. The Federal Ministry of Environment administers the EIA process, which includes screening, scoping, impact assessment, public participation, and review. The Supreme Court in Oronto v Attorney-General of the Federation (2001) 7 NWLR (Pt 711) 169 affirmed the mandatory nature of EIA requirements and the need for public consultation.

Oil Pollution Regulation

Oil pollution is regulated primarily through NOSDRA, established by the National Oil Spill Detection and Response Agency (Establishment) Act 2006. NOSDRA is responsible for coordinating oil spill response, monitoring cleanup operations, and enforcing liability for oil pollution. The Oil in Navigable Waters Act, the Petroleum Act, and the PIA 2021 also contain provisions addressing oil pollution. The PIA requires licensees to prepare environmental management plans, pay compensation for pollution damage, and remediate contaminated sites.

Waste Management

The NESREA (National Environmental Sanitation and Waste Management) Regulations 2009 govern waste management, including hazardous waste, electronic waste, and medical waste. The Regulations require waste generators to manage waste in an environmentally sound manner and prohibit illegal dumping and open burning. The National Guidelines on Hazardous Waste Management establish specific requirements for the generation, storage, transport, treatment, and disposal of hazardous waste.

Climate Change

Nigeria has enacted the Climate Change Act 2021, which establishes the National Council on Climate Change to coordinate climate policy and action. The Act sets a target of net-zero emissions by 2050 and requires the development of a National Climate Change Action Plan. The Act also mandates climate change education and public awareness. Nigeria is a party to the United Nations Framework Convention on Climate Change (UNFCCC) and the Paris Agreement.

Enforcement and Remedies

Environmental enforcement in Nigeria faces significant challenges, including limited regulatory capacity, overlapping jurisdiction, and procedural barriers to access to justice. The National Human Rights Commission has increasingly taken up environmental complaints as human rights issues. The courts have applied the polluter pays principle and have awarded damages for environmental harm, including in class actions by host communities. The African Charter on Human and Peoples Rights (Ratification and Enforcement) Act provides an additional avenue for environmental claims.

Conclusion

Nigerian environmental law has developed substantially, with a comprehensive statutory framework covering environmental impact assessment, pollution control, waste management, and climate change. The PIA 2021 and Climate Change Act 2021 represent significant recent advances. However, enforcement gaps, institutional capacity constraints, and the challenge of addressing legacy pollution in the Niger Delta remain significant obstacles to environmental protection in Nigeria.
