Section 20 of the 1999 Constitution reads, in full: 'The State shall protect and improve the environment and safeguard the water, air and land, forest and wild life of Nigeria.' Read in isolation, it appears to grant Nigerians a constitutional right to a clean environment. But s.20 sits inside Chapter II — Fundamental Objectives and Directive Principles of State Policy — and s.6(6)(c) of the same Constitution expressly provides that the judicial powers of Nigerian courts shall not extend to 'any issue or question as to whether any act or omission by any authority or person … is in conformity with the Fundamental Objectives and Directive Principles of State Policy.' In plain English: a Nigerian cannot sue the federal, state or local government for failing to protect the environment under s.20 alone. The right exists on paper; the cause of action does not.
The Federal High Court in Benin tried to break the wall. In *Jonah Gbemre v Shell Petroleum Development Company* (Suit FHC/B/CS/153/2005, judgment 14 November 2005), Justice C.V. Nwokorie held that gas flaring in Iwerekan community violated the right to life (s.33) and the right to dignity (s.34) — both justiciable under Chapter IV — when read together with Articles 4, 16 and 24 of the African Charter on Human and Peoples' Rights, domesticated by the African Charter (Ratification and Enforcement) Act 1983 and held by the Supreme Court in *Abacha v Fawehinmi* (2000) 6 NWLR (Pt 660) 228 to be directly enforceable in Nigerian courts. The Court ordered Shell to stop flaring within Iwerekan. The decision was a constitutional milestone: it routed around s.6(6)(c) by treating environmental harm as a *life* and *dignity* question, not a Chapter II question. Shell appealed. The Court of Appeal stayed the order pending appeal, and seventeen years later the appeal has never been determined. Gas flaring in the Niger Delta continues. The *Gbemre* route exists in theory; in practice no court has revisited it.
The absence of a directly justiciable environmental right is why Lagos and Abuja, in 2025, are both visibly dirtier than they were ten years ago, and why no resident has successfully sued either capital over it. Lagos generates an estimated 13,000 to 15,000 tonnes of solid waste per day — the highest urban waste output in sub-Saharan Africa — against installed treatment capacity of roughly 4,000 tonnes. The Olusosun Dump in Ojota (the country's largest, opened 1992) caught fire on 16 March 2018, releasing toxic smoke across the Ikeja–Lagos Island axis for three days; it caught fire again in 2019 and 2024.
## What Worked, What Broke — Lagos Waste, 2007–2024
The Fashola–Oresanya years (2007–2015) are the documented counter-example: a Nigerian megacity was, for almost a decade, measurably clean. The model that achieved this and the contract that destroyed it are both well-documented and worth setting out.
What worked (2007–2015). Governor Babatunde Fashola appointed Ola Oresanya as Managing Director of the Lagos Waste Management Authority (LAWMA) in October 2007 and gave him a five-year operational mandate. Oresanya restructured the agency on a four-pillar model. (i) PSP (Private Sector Participation) franchise: roughly 350 licensed private operators were each given an exclusive geographical zone for household and commercial waste collection. Residents paid the PSP directly at rates from ₦500 to ₦2,000 per household per month; defaulters were cut off after three months; the State took no fiscal exposure. (ii) Highway Managers (HMs): about 1,500 uniformed women, paid a basic LAWMA wage of ₦18,000/month plus a performance bonus, swept the arterial roads (Ikorodu, Third Mainland, Lekki–Epe, Apapa–Oshodi, Agege Motor Road) daily on three shifts. (iii) Engineered landfill capacity: three sites — Olusosun (Ojota), Solous II (Igando), Solous III (Igando) — were upgraded with leachate collection, daily soil covering and (at Olusosun) a methane-flaring contract signed in 2010 with the Dutch firm Coster Engineering under the Clean Development Mechanism, which generated certified emission reduction credits worth roughly €2.3 million per year to LAWMA. (iv) Enforcement: the Kick Against Indiscipline (KAI) Brigade, established 2003 by Tinubu and expanded by Fashola, ran mobile courts every Saturday at Oshodi, Yaba and Ojuelegba, fining street traders, illegal dumpers and open defecators on the spot at ₦5,000–₦25,000 per offence. By 2014, LAWMA was collecting and disposing of an estimated 9,500 tonnes per day — not enough to close the gap, but enough that Lagos arterials were visibly clean and the *Wall Street Journal* (December 2013) and the BBC (March 2014) ran 'African megacity that works' features citing LAWMA by name.
What broke (2017–2019). Governor Akinwunmi Ambode scrapped the entire PSP model under the Cleaner Lagos Initiative (CLI) announced in July 2017 and operational from January 2018. CLI awarded a single ten-year monopoly contract for all Lagos waste collection to Visionscape Sanitation Solutions — a company registered in the British Virgin Islands two months before bidding, with no demonstrated waste-collection track record anywhere in the world, whose ultimate beneficial owners were never publicly disclosed. The contract value was reported at US$ 135 million for trucks and equipment, financed by a Lagos State ₦27 billion infrastructure bond issued in October 2017. The PSP operators, with their 2,400 trucks and 12,000 employees, were summarily decommissioned. Visionscape arrived with roughly 220 trucks for a city that had been served by 2,400 — a 90 % capacity collapse on day one. Refuse mounds rose on every street; by April 2018 Lagos Island and Surulere had stretches where uncollected waste was taller than the parked cars. The Olusosun fire of 16 March 2018, which closed the Ikorodu Road for three days, was widely attributed to spontaneous methane ignition in waste that had not been daily-covered for two months because Visionscape had no landfill operations team. The KAI Brigade lost enforcement authority because there were no working bins to direct waste to. The CDM methane-flaring contract was terminated for non-performance in 2019.
Why the contract was the problem. Three reasons, in descending weight. First, monopoly displaced redundancy: 350 small PSP failures in 2014 affected one zone each; a single Visionscape failure in 2018 affected the entire metropolis. Second, vertical integration without capability: Visionscape was simultaneously responsible for collection, transport, landfill operation, billing and customer service across 22 million people, with no prior operational experience in any of them. Third, and most importantly, the billing model: CLI proposed to bill households through a consolidated utility levy on electricity bills, which required cooperation from the Discos, the Nigerian Electricity Regulatory Commission and federal-level legislation; none of those approvals were obtained before operations began, and the revenue line collapsed within four months.
The reset (2019–present). Governor Babajide Sanwo-Olu, on taking office in May 2019, terminated the Visionscape contract and reinstated the PSP operators under an emergency framework. Roughly 270 of the original 350 PSPs returned (many had laid off staff and sold trucks in the intervening eighteen months); LAWMA absorbed the residual collection in zones where no PSP could be re-mobilised. The 2024 LAWMA reset introduced 480 new compactor trucks procured from China under a US$ 78 million counter-trade arrangement, restructured tipping fees, and re-opened the methane-flaring contract at Olusosun under a new operator. The system is functioning at roughly 60–70 % of the 2014 Fashola–Oresanya capacity as of late 2024. The Epe Sanitary Landfill, designed to replace Olusosun and Solous, has been under construction since 2017 and is still not operational; Olusosun, officially declared full in 2018, continues to receive about 5,000 tonnes per day because there is nowhere else to put it.
The lesson from Lagos's working decade is structural: distributed franchise + direct billing + enforcement + engineered landfill capacity is the model that has cleaned a Nigerian megacity. The lesson from the failed contract is governance: a single ten-year monopoly awarded to a newly-formed offshore vehicle with undisclosed beneficial ownership is a model that destroys a working system in nine months. No Nigerian court has heard a case on the Visionscape contract; the constitutional gap identified at the start of this story means no resident could have stopped it ex ante and no resident can demand restitution ex post.
## Abuja
Abuja is structurally worse, because the capital was designed for a planned population of 1.6 million and now holds an estimated 3.8 million. The Mpape Dump (the FCT's only operational landfill, 30 km from the city centre on the Bwari road) regularly overflows; the Gosa Dump and the Ajata-Aboki Dump were closed by FCT Administration order between 2019 and 2022 after community protests over leachate seepage into the Usuma River, which feeds Lower Usuma Dam — Abuja's only treated-water source. The Abuja Environmental Protection Board (AEPB) has been reorganised five times since 2007 and at the time of writing operates roughly 220 functional collection vehicles for a city of 3.8 million; field surveys by the Centre for Communication and Social Impact (2023) found that uncollected refuse accumulates in Wuse II, Garki II, Kubwa, Mararaba and Lugbe for an average of 9–14 days between collections. The Federal Capital, which is meant to be the constitutional showcase, runs on the same gap between the printed s.20 promise and the unenforceable absence of a remedy.
The second constitutional gap is air. Nigeria ratified the Paris Agreement in 2017 and enacted the Climate Change Act 2021 establishing the National Council on Climate Change, but neither instrument creates an individually enforceable right. The NESREA Act 2007 allows the National Environmental Standards and Regulations Enforcement Agency to fine industrial emitters and seal facilities, but its standing is administrative, not constitutional; a citizen who is poisoned cannot sue NESREA for failing to act. Lagos's ambient PM2.5 routinely exceeds 70 μg/m³ (WHO guideline: 5 μg/m³); generator exhaust from 60 million household and commercial diesel/petrol generators is the largest single source. No Nigerian court has held that this violates the right to life.
The third gap is water. The *Mobil Producing Nigeria Unlimited v LASEPA* line of cases (2002 onward) made clear that state environmental agencies have *administrative* power to require remediation of oil spills, but the citizen's direct constitutional remedy remains unclear. The 2011 UNEP Ogoniland Assessment documented hydrocarbon contamination of drinking-water wells 900 times above WHO limits in Nisisioken Ogale; fourteen years and the HYPREP clean-up programme (set up 2016) later, only a small fraction of the contaminated sites have been remediated, and no Ogoni resident has won a Nigerian constitutional remedy for the contamination — though the UK High Court permitted *Okpabi v Shell* (2021) UKSC 3 to proceed in London precisely because the Nigerian constitutional route was inadequate.
The reform proposals are well-known and unimplemented. The 2014 National Conference Report recommended moving s.20 (and other Chapter II rights) into Chapter IV, making them directly justiciable; the recommendation went into the report and stayed there. The Constitution Alteration Bill No. 47 (2019) in the 8th National Assembly proposed the same; it failed at the State Houses of Assembly stage. The Constitution Review Committee of the 10th NASS (2023–2025) has the proposal on its 47-item agenda; as of the time of writing it has not been voted on. Until and unless Chapter II becomes justiciable, or until the *Gbemre* African-Charter route is affirmed by the Supreme Court, Nigerians will continue to live in a country where the state is constitutionally instructed to protect the environment and constitutionally protected from being sued when it does not. The rumour the question was built on is correct in substance: there is no defensible Nigerian constitutional right to a clean environment, and the dirt in both capitals is the visible proof.
