Malta set to miss 2030 traffic-induced NOx emission reduction target

New government projections show the country remains at significant risk of failing to meet its legally binding 2030 nitrogen oxide (NOx) emission reduction targets.

The warning emerges from the latest update to Malta’s National Air Pollution Control Programme (NAPCP), published for public consultation by the Environment and Resources Authority (ERA) in June 2026.

While Malta is currently compliant with all major pollutant ceilings for 2020 but NOx stands out as the only pollutant projected to breach its stricter 2030 limits.

According to the analysis, the gap remains substantial. Under the ‘With Measures’ (WM) scenario—which assumes only already adopted policies are implemented—NOx emissions are projected to reach 3.88 kilotonnes by 2030. This is nearly double the legally permitted ceiling of 1.98 kilotonnes.

Even under a more ambitious ‘With Additional Measures’ (WAM) scenario, which includes further policy proposals mostly consisting of incentives rather than prohibitions, Malta is still expected to fall short of compliance, underscoring the scale of the challenge ahead.

Road transport accounts for 43% of emissions

The road transport sector remains the dominant source of NOx pollution, accounting for 42.6% of national emissions in 2023. Passenger cars, buses and heavy-duty vehicles together produce the bulk of the estimated 4.22 kilotonnes emitted annually.

Maritime activity also contributes significantly, with national navigation and shipping—particularly the Gozo Channel and fast ferry services—accounting for 15.5% of total NOx emissions.

To narrow the gap, government has outlined a package under the ‘Reshaping Our Mobility’ initiative, largely centred on incentive-based measures intended to encourage a gradual shift away from private car use rather than regulatory restrictions.

But rather than recommending a more radical approach aimed at reducing emissions on a year-to-year basis the document lists a number of already announced proposals. These include the ‘Surrender Your Licence Scheme’, which would offer citizens up to €25,000 over five years to give up their driving licence and car ownership. A separate ‘Be the Change 17+’ programme targets younger residents, offering €6,000 in grants to 17-year-olds who opt for scooter use and delay obtaining a car licence until age 21.

The strategy also includes wider system changes such as a proposed ‘24-Hour Economy’ model, shifting public services, road maintenance and deliveries to off-peak hours to reduce congestion. On the infrastructure side, measures include retrofitting a Gozo Channel vessel to Tier III NOx standards and developing the Melita Transgas hydrogen-ready pipeline to support energy-sector decarbonisation by 2030.

Despite these measures, the NAPCP acknowledges that closing the emissions gap remains uncertain.

Malta’s insistence on flexibility

A central feature of Malta’s approach is its request for flexibility under the EU’s National Emission Ceilings (NEC) Directive, departing from the standard linear reduction trajectory required between 2020 and 2030. Instead, Malta is applying a non-linear path that converges with the required emissions trajectory only after 2025.

This approach is justified by a national socio-economic study which found that a strict linear pathway would impose an “excessive additional burden” on low and middle-income households. The government argues that such rigidity would risk disproportionate social costs, conflicting with the directive’s requirement that environmental measures remain economically balanced.

Crucially the term “excessive burden” is not defined by a specific monetary threshold or a set of criteria; rather, it is presented as a finding from a national high-level socio-economic study. This study determined that the measures required to meet Malta’s 79% Nitrogen Oxide (NOx) reduction target by 2030 through a strictly linear path would have significant socio-economic impacts. In this context, “linear trajectory” refers to reducing emissions by a consistent amount each year. The study found that forcing this straight-line progress would be too financially punishing for vulnerable households. But the alternative scenario of compensating this ‘burden’ with other social measures is not considered.

While the flexibility mechanism is explicitly grounded in socio-economic considerations, it also leaves Malta relying heavily on delayed convergence and incentive-based measures. This raises broader questions about the level of political appetite for more restrictive interventions in a context where private car dependence remains deeply entrenched.

The revised approach therefore seeks to balance economic and social pressures with environmental obligations, but the programme itself concedes that even with these flexibilities and additional measures, achieving the 2030 target is not guaranteed.
