Transport is a vital sector but our current mobility system is simply not sustainable. Decisive policies, smart investments and changes in demand can trigger a vital shift towards cleaner transport modes and reduce the sector’s impact on the environment, climate and our health.

Difficult journey ahead to sustainability, despite progress

The EU is making progress towards climate neutrality but reductions in greenhouse gas emissions from transport are relatively stagnant. According to our latest report on transport and environment, the transport sector’s transition towards sustainability is made difficult by the increasing transport demand and sluggish growth in sustainable transport modes for moving both people and freight.

The EEA report ‘Sustainability of Europe’s mobility systems’ sums up transport sector’s key trends as of 2024, and their environmental and climate impacts. The report shows that transport remains a major source of greenhouse gas emissions, air pollution and noise. While projections for 2030 and beyond show some positive signs, substantial investments in implementation of innovative solutions and a shift to more sustainable transport modes are still needed.

Aviation sector must continue to improve to meet environmental and climate goals

Aviation has produced economic benefits, stimulated innovation and improved connectivity within Europe. But unfortunately, this growth has also increased negative impacts on climate change, noise and air quality.

Air traffic in Europe decreased during the COVID pandemic, but it has recovered to 8.35 million flights in 2023, only 10% below the 2019 level. Longer-term trends suggest that this will grow to 11.8 million annual flights by 2050. 

Technological improvements such as more fuel-efficient technology, optimisation of operations, and use of Sustainable Aviation Fuel, aims to decouple traffic growth from emissions. Additional market-based measures will also be needed if the sector is to achieve net-zero CO2 emissions by mid-century.

These are some of the conclusions from the 4th edition of the European Aviation Environmental Report (EAER) published by the European Union Safety Agency (EASA) with support from the EEA.

Train or plane? The most sustainable is...

An earlier edition of our transport and environment report (TERM) 2020 looks into the impacts of rail and air travel, both of which are a big  part of Europe’s passenger transport sector. It concludes that rail travel is the best and most sensible mode of travel, apart from walking or cycling. 

Aviation’s emission impacts are much higher on a passenger-kilometre basis. But flying is not necessarily the most harmful choice. Travel by a petrol or diesel-powered car, especially if traveling alone, can be more harmful.

A shift from air to rail travel can play a crucial role in helping the EU meet its objective of reducing greenhouse gas emissions from transport by 90% by 2050 compared with 1990.

How can Copernicus help?

What if the ground is moving? Are our road and rail transport networks stable enough?

Copernicus is the European Union's earth observation programme. It combines detailed geospatial data obtained through satellites and from ground observations.

Information on surface displacement due to geohazards or human activity is provided by the European Ground Motion Service (EGMS), provided by the EEA, within the Copernicus Land Monitoring Service.

This can be used to monitor subsidence affecting airport runways, railways, or breakwaters in ports. It enables the shift from air to rail travel by helping to identify the best routes and tracks.
