An environmental expert has called for urgent policy action to address rising air pollution in Lagos.

Weyinmi Okotie, clean air quality and energy manager for the Global Alliance for Incinerator Alternatives, made the call in an interview in Lagos.

The expert spoke against the recent air quality data released by the Lagos State Environmental Protection Agency on Monday at 10.00 a.m.

LASEPA said air quality across Lagos remained largely moderate to good as of 10:00 a.m. on April 20.

It reported that Arepo along the Lagos-Ibadan Expressway recorded the highest Air Quality Index of 60.1, indicating unhealthy levels for sensitive people. The Arepo and Lagos-Ibadan areas show increased pollution levels.

It added that Oshodi Bus Terminal and Abiola Garden recorded AQI values of 22.6 and 20, respectively, which fall within the moderate category.

According to LASEPA, Oyingbo Red Line Station, Admiralty Way, and Ojuelegba Bus Terminal recorded good air quality levels.

The agency noted that its headquarters recorded the lowest AQI of 5, indicating clean air conditions. It attributed higher readings in some areas to traffic density and human activities.

Reacting, Mr Okotie described the Arepo reading as troubling. He attributed it to heavy traffic congestion and emissions from ageing diesel trucks and commercial vehicles.

According to him, the corridor remains highly polluted due to poor regulation of freight activities and prolonged gridlocks.

He called for strict enforcement of vehicle emission standards and a shift towards rail freight.

The expert, however, commended LASEPA for consistent and transparent air monitoring. According to him, real-time, location-specific AQI data provides critical insight for policy decisions.

He also praised Nigeria’s transition to 50 parts per million sulphur fuel. According to him, the policy helps reduce harmful emissions and supports improvements in air quality.

He urged authorities to accelerate the phase-out of old and high-emission vehicles.

The expert restated the need for improved urban planning to reduce congestion and expand green spaces. He highlighted the impact of generator emissions on air quality in residential and commercial areas.

According to him, reliance on petrol and diesel generators contributes significantly to background pollution. He noted that “good” AQI ratings may not reflect peak pollution periods during heavy generator use.

The expert called for incentives to promote the adoption of clean energy, including solar and inverter systems. He said such measures would significantly improve air quality outcomes.

The expert urged policymakers to act decisively using available data to protect public health and the environment.
