Regulating the Port, Not the Showroom: Ghana’s First Zero-Emission Vehicle Supply-Side Regulation

Almost every vehicle that joins Ghana’s fleet arrives already built, already used, and already someone else’s decision. It is landed at a port, cleared, registered and sold. By the time a Ghanaian buyer stands in front of it, the vehicle’s efficiency, its emissions profile, its drivetrain and its remaining service life were all settled years earlier, on another continent, by a first owner who has never heard of Ghana’s Nationally Determined Contribution.

That single fact reorganises the entire electric mobility policy problem. Between April 2025 and April 2026 I coordinated Ghana’s first zero-emission vehicle supply-side regulatory framework for the UN Environment Programme and the ClimateWorks Foundation. This is an account of why the instrument had to target the border rather than the buyer, and what it actually takes to move something like that from a model file to a document formatted for government adoption.

The ceiling on demand-side policy

I came to this from the demand side. From July 2024 to April 2025 I coordinated Ghana’s NDC Action E-Mobility Policy Working Group for UNEP with Base Foundation, running the national stakeholder process and holding the group’s outputs against the country’s NDC commitments. That work covered the familiar instruments: adoption incentives, charging infrastructure, capacity building, public awareness.

Demand-side instruments are not wrong. They are simply bounded by what is on the lot. You can zero-rate the duty on an electric vehicle, publish a charging roadmap and run a national awareness campaign, and still find that the fleet composition barely moves — because the constraint was never Ghanaian preference. It was the shipping decision made by an exporter matching surplus stock to a market with permissive entry conditions.

A demand incentive in a used-import market is an offer to choose more enthusiastically from a menu that someone else already wrote.

Supply-side regulation writes the menu. It governs what may be brought in at all: minimum performance and emissions thresholds, vehicle age conditions, safety and homologation requirements, conformity assessment at entry, and — critically — the regulatory definitions that determine what counts as a zero-emission vehicle in the first place. Change the entry conditions and you change the fleet that exists to be chosen from.

Modelling before drafting

A supply-side regulation is, in its operative parts, a set of numbers. Thresholds, dates, categories, phase-in steps. And a threshold with nothing behind it is a number that will be negotiated downward by whoever is most affected by it, because there is no principled reason to defend any particular value.

So the sequence mattered. The programme ran technical modelling first, then drafting. That order is what allows a coordinator to answer the only question that matters in a stakeholder room — why that number and not a looser one — with an analysis rather than an assertion. It also makes the phase-in defensible: if you can show what a threshold does to import volumes, to fleet turnover and to the emissions trajectory, then a request to relax it becomes a request to accept a specific, quantified cost rather than a general appeal to commercial hardship.

The room

Getting a single instrument out of that analysis meant convening the Ministry of Transport, the Energy Commission, the Environmental Protection Agency, the Driver and Vehicle Licensing Authority, the Ghana Standards Authority, vehicle importers and dealers, and development partners.

These parties do not naturally agree, and it is worth being precise about why. Each holds a different piece of the border. The Standards Authority owns conformity assessment. The DVLA owns registration — the moment at which a vehicle becomes legally real. The EPA owns the emissions mandate. The Energy Commission owns the electricity side, without which a zero-emission vehicle is a stranded asset. The Ministry of Transport owns the policy lead. And the importers and dealers own the actual trade the instrument is about to constrain, with a business model built on precisely the vehicles a supply-side threshold is designed to screen.

Convening them around one instrument, rather than allowing five parallel and mutually inconsistent positions to form, was most of the work. The alternative is well known in this region: an instrument drafted by technical assistance, launched at a hotel, and then unenforced because the agency that had to operationalise it at the point of registration was never in the room when the thresholds were set.

The validation workshop is not a presentation

The national validation workshop is the step people outside this work tend to misread as ceremonial. It is not. It is the moment at which authorship transfers — where a draft stops being the consultants’ document and becomes the stakeholders’ document, on the record, with objections registered and resolved rather than deferred.

It also produces an artefact with real downstream weight. The validation workshop report is what a ministry cites when it needs to demonstrate that an instrument has an evidenced constituency behind it. I co-authored that report alongside the policy brief, the ECOWAS dissemination report and the final policy document.

Formatting for adoption, which is where this work usually dies

The least glamorous decision in the whole programme was also the most consequential: the final policy document was formatted to National Development Planning Commission standards.

That sentence is easy to skim past. It means the output was built to enter the Government of Ghana’s own planning and adoption route — its structure, its conventions, its expectations for how a policy proposition is presented — rather than arriving as a well-argued PDF in a format the receiving institution has no established process for.

A great many technically excellent instruments never become policy because they were written for the funder’s reporting cycle rather than the government’s adoption pipeline.

If the receiving institution has to reformat, restructure and re-argue your work before it can be tabled, you have not handed over an instrument. You have handed over homework.

When a national instrument becomes a regional conversation

Then the geography asserted itself. West African vehicle import markets are interconnected. Tighten entry conditions in one country and the vessels do not stop sailing — they redirect to the neighbour with the more permissive regime, and the vehicles arrive by road soon after. A national supply-side standard, taken alone, is at least partly a redirection instrument.

So dissemination was not an afterthought bolted on at the end of the budget. I designed and led a sub-regional ECOWAS webinar series on supply-side regulation for electric mobility, reaching 51 stakeholders across 9 countries. The purpose was to put the analysis in front of the officials in neighbouring administrations who would otherwise only encounter Ghana’s standard as a sudden change in their own import mix.

That is the turn I find most interesting about the whole programme. The instrument was designed for one country and, on contact with the region, immediately posed a regional question: whether West Africa converges on entry conditions or competes to be the softest port of entry. Fifty-one people across nine countries is not a treaty. It is the beginning of the conversation in which one becomes conceivable.

What I take from it

I presented on the supply-side determinants of Africa’s electric vehicle transition at the Fourth Tsinghua Global Youth Dialogue, and the argument I made there is the one this work taught me. The continent’s transport transition will not be decided primarily by what African consumers want. It will be decided by what the rest of the world decides to stop driving, and by whether African regulators set the conditions under which those vehicles are allowed to land.

That is a less romantic story than the one usually told about electric mobility. It is also, I think, the accurate one — and it is considerably more actionable, because import conditions are a lever that a national regulator genuinely holds.
