Climate Metrics and targets
Measuring progress. Driving climate action.
We set ourselves targets that are ambitious and reflective of the stage we, and our businesses, are at on our sustainability journey.
The way we work with our businesses follows the GHG Protocol Corporate Standard to assess our GHG emissions, using CO2 equivalent (CO2e) which considers CO2, CH4 and NxO. While we actively manage sustainability across our entire portfolio, the way we work with our businesses to drive sustainability progress differs according to the extent of our ownership. Up until the end of 2025, we have used an equity-share boundary. From 2026 we are proposing to use an operational control boundary, which better reflects our new vision, which was updated in May 2025.
Scope 1 and 2 GHG Emission Targets
OUR 2025 GHG REDUCTION TARGETS
Aligned with the Science Based Targets initiative (SBTi) 1.5 degree warming scenario and calculated using an equity share boundary
> 25%
reduction in scope 1 and 2 emissions by 2025
> 46%
reduction in scope 1 and 2 emissions by 2030 compared to 2019 baseline.
OUR 2026 GHG REDUCTION TARGETS
Aligned with the Science Based Targets initiative (SBTi) 1.5 degree warming scenario and calculated using an operational control boundary
≥75%
wholly and majority-owned businesses and Corporate not less than 75% reduction in scope 1 and 2 emissions by 2030 compared to a 2019 baseline
Targets independantly maintained at minority owned businesses
(APRR’s target of 46% reduction in scope 1 and 2 emissions by 2030 compared to 2019 baseline remains unchanged)
Scope 1 and 2 GHG Emission reduction initiatives
At our wholly and majority-owned businesses our emission reduction initiatives have focussed on reducing our scope 2 emissions through lighting and equipment replacement to reduce energy use, the installation of an own-use solar system at Warnow Tunnel and the purchase of renewable electricity. Similar measures are in place at APRR, which also has a scope 1 reduction plan in place including electrification of their light vehicle fleet and the use of lower carbon HVO fuel in diesel vehicles.

Scope 3 GHG Emissions - Our Suppliers
We follow the Greenhouse Gas Protocol in calculating our scope 3 emissions, which divides scope 3 emissions
into upstream and downstream sources.
Upstream scope 3 emissions are generated by suppliers to enable our businesses to provide roadways, infrastructure and supporting services. We primarily estimate these emissions using the spend based methodology. The majority of our scope 3 upstream emissions fall into Category 1 – Purchased Goods and Services and Category 2 – Capital Goods. While our scope 3 upstream emissions are currently tracking well ahead of the SBTi 1.5 degree warming pathway, the use of the spend methodology means that this is largely based on spending. This calculation of emissions is therefore sensitive to increases in spending, such as potential increases in capital expenditure.
- Note that customer emissions are not included in the SBTi pathways. The two SBTi pathways are Well Below 2 degrees (WB2), relating to a reduction equivalent to 2.5% of the 2019 baseline each year, or 1.5 degree, relating to a reduction equivalent to 4.2% of the 2019 baseline each year.
Scope 3 GHG Emissions - Our Customers
The overwhelming majority of Atlas Arteria’s total scope 1, 2 and 3 emissions are generated by our customers. Although we can’t directly control these emissions, we remain committed to empowering our customers to reduce their carbon footprint as they travel on our roadways. We do this by providing technology (such as electric vehicle charging stations) and infrastructure (such as free-flow tolling, carpool lanes and car parks, bike lanes and multi-modal hubs for better connectivity to public transport) to give customers greener travel options. All service areas across the APRR have been fitted with charging stations for electric vehicles since the end of 2022.
World-first initiative at APRR supports electrification of the transport sector
Heavy vehicles account for about 40% of transport-related CO2 emissions. That’s why APRR has
partnered with ENGIE in a world-first initiative on a highway to install five (of the six total) charging stations
for electric heavy vehicles and long-distance coaches along its network. The stations are located approximately 150 kilometres apart between Lyon and Paris and offer 400‑480 kW charging power
per terminal. This initiative represents a significant step in the decarbonisation of the transport sector
and is expected to prevent approximately 40,000 tonnes of CO2 emissions over 10 years.
APRR offering access to greener ways to travel
APRR continues to empower its customers with multiple ways to reduce their carbon footprint. During the year, they added an additional 118 carpooling spaces across two new carpooling car parks. This brings the total number of carpooling spaces to more than 5,800, across 76 car parks. Carpooling offers customers an option to travel to one of APRR’s car parks, safely park their vehicles and travel in a carpool arrangement with others in dedicated carpool lanes.
They also commissioned a new multi-modal hub that features 100 carpooling spaces, a new pedestrian bicycle route that links directly to the car park and two bus stops. This two-way area makes it easier for people to use different forms of travel to reach their destination. So, when motorists leave the motorway, they can park their car for the day and opt for another means of transport (either shared or public) to get where they need to go in a faster and more environmentally friendly way.
