Environmental Regulatory Monitoring & Compliance

Are you compliant?

Streamlined Aviation Emissions Regulatory Reporting

Our regulatory program keeps track of your flight operations to notify you of any compliance requirements that may arise. We can forecast potential compliance costs, avoiding unnecessary end of year surprises, and allocate costs flight by flight.

If a threshold is met or if your operations extend to a location where emissions reporting is mandated, we seamlessly provide a comprehensive compliance solution for you.

Our all-inclusive service streamlines the emissions reporting process, giving you the convenience of an automatic pilot for regulatory compliance.

Monitoring and Compliance for Environmental Obligations

Becoming subject to an environmental obligation could be as simple as flying to or from a participating state or triggering certain emission thresholds. Don’t be surprised with unexpected compliance obligations or penalties, let 4AIR monitor potential obligations with a monitoring subscription.

Monitoring

ETSs have grown substantially in prior years, covering 18% of global emissions today.

Ensure compliance with environmental obligations by subscribing to our monitoring services. 4AIR takes the burden off your shoulders by tracking various programs based on your flight activity. Our monitoring covers potential obligations under programs including:

  • CORSIA

  • EU & Swiss ETS

  • UK ETS

  • Refuel EU

  • Portugal Carbon Tax (PCT)

  • Plus more than 20 additional passenger duties and adjacent reporting requirements.

4AIR also monitors new and emerging aviation requirements to ensure that your missions remain current from a regulatory perspective as the industry evolves.

Compliance

If compliance becomes necessary, we offer a comprehensive compliance package to handle all your reporting obligations. With 4AIR, you can trust that we will draft monitoring procedures, conduct internal quality assurance checks, complete annual reports, bring in third-party auditors, provide allowances, and ensure your operation remains compliant with evolving environmental obligations.

Let 4AIR put your compliance on autopilot

 

CORSIA

What is CORSIA?

The Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) is an initiative that the International Civil Aviation Organization (ICAO) has made mandatory for some operators to monitor, report, and verify CO2 emissions on international flights. The goal is to cap international emissions by using carbon offsets or SAF to reduce emissions. Multiple phases exist for CORSIA through 2035 with evolving baseline and offset requirements.


Check if you are required to comply with CORSIA:

Operators of aircraft within participating CORSIA countries that have a Maximum Take Off Weight (MTOW) greater than 5,700 kg (12,566 lbs) or emit 10,000 metric tons of CO2 or more, may need to comply. Offsetting and reporting requirements will only apply if thresholds are passed on non-excluded flights between participating countries, but monitoring requirements may still apply.


EU, UK, Swiss & French ETS, ReFuelEU, Portugal Carbon Tax 

What is EU-ETS?  

The European Union Emissions Trading System (EU ETS) is a cornerstone of the EU's policy to combat climate change and its key tool for reducing greenhouse gas emissions cost-effectively. It is the world's first major carbon market and remains the biggest one. If you are operating flights in the European Union and emit 1,000 metric tons of CO2 or more, you will likely need to comply. 

2025 Contrail MRV under EU ETS

Revised EU ETS legislation, effective from 2025, requires aircraft operators included in the EU ETS scheme to monitor and report not only CO2 but also non-CO2 aviation effects. These effects include oxides of nitrogen (NOx), soot particles, oxidized sulfur species, and effects resulting from water vapor, such as contrails. 

Free Allowances

To increase the uptake of sustainable aviation fuels (SAF) and cover the SAF price premium, 20 million EUAA allowances will be distributed for free between 2024 and 2030. Aircraft operators may apply for these free SAF allowances based on the amount of SAF they report in their annual EU ETS emissions report. 

 

What is UK ETS?  

The United Kingdom Emission Trading System is very similar to the EU ETS but is specific to operations in/out of the United Kingdom. 

 

What is Swiss ETS? 

Operators participating in the EU ETS and conducting domestic flights within Switzerland or flights from Switzerland to the EEA or the UK may also be subject to the Swiss ETS. 

 

What is the French ETS? 

Operators subject to the EU ETS may also be subject to the French ETS if they fly domestically within France and surpass certain thresholds.  

 

What is ReFuelEU? 

Operators flying more than 500 flights from larger European airports are subject to the ReFuelEU program, which includes yearly reporting requirements and specific tankering restrictions. 4AIR can help manage and automate your ReFuelEU monitoring and reporting requirements.

 

What is the Portugal Carbon Tax? 

Operating flights from any Portuguese airport on a business aircraft may incur a special carbon tax per passenger flown. 

 

Do you need to comply? 

Flying to or from a European airport may trigger a reporting requirement. Reach out to 4AIR to ensure your flight activity is compliant.
