Jersey Airport achieves ACA Level 4 carbon accreditation — what businesses can learn from it

Jersey Airport has been awarded Level 4 “Transformation” under the Airport Carbon Accreditation (ACA) programme, run by ACI EUROPE. The accreditation places it among 96 airports across Europe to hold the status — and recognises that the airport has moved beyond measuring and managing its emissions to setting longer-term targets and working with airlines, tenants, and suppliers to reduce its wider environmental impact.

What Ports of Jersey has actually done

The accreditation didn’t come from offsetting. It came from operational changes:

• Hydrotreated Vegetable Oil (HVO) — operational vehicles, ground equipment, and terminal heating systems switched from diesel to HVO, a renewable diesel alternative that drops straight into existing engines.
• Renewable BioLPG — the Fire Training Ground moved from conventional LPG to renewable BioLPG, reducing emissions from a mandatory operational activity.
• LED lighting and smart metering — energy-efficiency retrofits across the terminal, with building management systems (BMS) to monitor and control consumption.
• Continuous Climb and Continuous Descent procedures — aircraft operations changed so planes climb and descend more efficiently, reducing fuel burn and emissions per movement.
• Private & Business Aviation Decarbonisation Charge — a new charge on private and business aviation that funds future carbon-reduction projects at the airport.

Ports of Jersey has set a target of net-zero Scope 1 and Scope 2 emissions by 2030— covering emissions from its own operations and energy use. Sophie Alexander, head of sustainability and community at Ports of Jersey, said the accreditation recognised “a fundamental shift in the way we think and operate,” with sustainability “increasingly shaping our decisions, investments and future plans.”

Why this matters for Jersey businesses

Jersey Airport is one of the island’s largest infrastructure operators. When an operation of that scale commits to net-zero Scope 1 & 2 by 2030 — eight years ahead of the government’s 2050 target — it sets a benchmark for what’s achievable locally.

The measures Ports of Jersey has taken map directly to what businesses of any size can do:

The pattern: measure, switch, invest

What Jersey Airport’s accreditation shows is a three-step pattern that any business can follow:

1. Measure— you can’t reduce what you don’t track. The airport had to quantify its Scope 1 and Scope 2 emissions to enter the ACA programme.
2. Switch — replace fossil fuel sources with lower-carbon alternatives. HVO for diesel, BioLPG for LPG, LED for halogen. These are drop-in replacements, not wholesale redesigns.
3. Invest — use a funding mechanism (the decarbonisation charge) to pay for future reductions rather than relying on existing budgets.

321ZERO helps with step one. You enter the data you already have — electricity bills, fuel receipts, vehicle mileage — and the platform applies Jersey-specific factors to give you your Scope 1, 2, and 3 emissions. Once you know your baseline, the switching and investing decisions follow.

The 2030 signal

Ports of Jersey is targeting 2030 for Scope 1 & 2 net-zero — not 2050. That’s the signal businesses should pay attention to. Major local operators are moving faster than the government mandate. Suppliers, tenants, and contractors to the airport will increasingly be asked about their own emissions as part of the airport’s Scope 3 reduction efforts.

If your business supplies, delivers to, or operates from Jersey Airport — or any large organisation setting similar targets — expect carbon questions in procurement. 321ZERO gives you the numbers to answer them.
