An Post’s 2025 Sustainability Report marks huge carbon reduction milestone
19 May 2026
In 2025:
- An Post achieved its 50% carbon emissions reduction target, three months ahead of schedule.
- EVs made up more than 50% of An Post’s delivery fleet, and 95% of its HGVs switched to HVO fuel, slashing emissions for communities and employees.
- 99% of An Post’s buildings were powered with green energy.
- The Circular Economy exploded in popularity with millions of pre-loved items sold or donated via An Post’s digital platforms, post offices and delivery services.
- Government approval is awaited for An Post’s self-funded construction of major ecommerce infrastructure to power Ireland’s trade for the next 30+ years, and to deliver Net Zero carbon by 2030.
An Post’s 2025 Sustainability Report, released today, shows how the Company continues to make significant progress in carbon emission reductions and green energy usage, all the time dealing with record parcel growth - up 27% to 73 million items last year.
An Post achieved a 50% reduction in carbon emissions in September 2025, three months ahead of schedule, compared to 2009 levels, becoming one of the first national postal carriers in the world to reach this milestone while simultaneously growing its business and profits. The original target of a 50% CO2 emissions reduction by 2030 was set in 2017; however, in 2021, An Post brought forward this target to the end of 2025, reflecting the urgency of delivering climate action and pursuing Ireland's sustainability goals.
By servicing 2.5 million delivery points every working day and serving up to 1 million customers a week in Post Offices, the report showcases An Post’s wider efforts to accelerate its hugely positive environmental and social impact for communities across Ireland.
Driving positive change
In its continued commitment to drive positive environmental change, An Post’s ongoing investment in low-carbon transport and green energy has seen the large commercial semi-state business achieve a 50% reduction in carbon emissions in 2025, three months ahead of schedule.
By making steady progress with the electrification of its delivery fleet, 55% of An Post’s total fleet was alternatively fuelled by year-end 2025. So far this year, 575 new, larger EVs have been deployed, 30% of which replaced diesel vans. The remainder have replaced smaller, first-generation EVs which had lower battery range.
The Report also shows that 95% of An Post’s heavy goods vehicles switched from diesel to renewable Hydrotreated Vegetable Oil (HVO) in Q4 of 2025. This required An Post to invest in HVO tanks and refuelling infrastructure in its Athlone, Dublin and Portlaoise main hubs. HVO provides up to a 90% reduction in greenhouse gas emissions per litre compared to conventional diesel, creating a quieter, healthier environment for communities and An Post employees nationwide.
Having maintained its ranking of 4th in the world in the International Postal Corporation (IPC) Sustainability Measurement and Management System, An Post remains actively committed to its wider ambition - to make sustainable living commonplace in Ireland.
Circular Economy
The Sustainability Report also highlights the company’s leadership in the realm of the circular economy, particularly in relation to clothing and homewares with more than 5 million item items sold or donated via An Post’s digital platforms, post offices, pre-paid packaging and delivery services in 2025 alone. In line with its Green Light strategy, An Post will continue to innovate in support of reuse, recycle initiatives for consumers and businesses.
Green energy goals
Managing smarter energy use across An Post's property portfolio forms part of a wider initiative to decarbonise operations across the organisation. 99% of An Post buildings are now powered with green energy It also reveals and the company’s headquarters at The EXO in Dublin’s North Wall saw energy usage drop by a sizable 250 MWh in 2025, reflecting continued optimisation of building systems in the LEAD Platinum status building.
Speaking about the findings of the An Post Sustainability Report, David McRedmond, CEO at An Post, said:
“The battle for sustainability never ends, and the need is as great as ever. Extreme weather in Ireland brings home the real impact of global warming, which is why for my colleagues sustainability is not a fashion but an imperative.
“We are now over halfway to achieving our net-zero emissions goals by 2030. This is made possible by the fact that 99% of our buildings are now powered with green energy, upgrading BER and introducing smart heating controls. In the midst of an energy crisis, we have continued to accelerate our environmental ambition in tandem with the ever-increasing demand for delivery services and fleet usage.
“An Post will continue to be a champion of sustainability whilst leading positive environmental change. It’s vital that we are able to move ahead at pace with constructing the ecommerce and postal sorting and delivery infrastructure for the future, to be funded from our own resources, once Government approval is received”, he concluded.
Owen Keogh, An Post Head of Sustainability, added:
“Our latest Sustainability Report demonstrates how sustainability and commercial success can advance collectively. With 575 new, larger EVs being deployed in the first half of this year and a tighter focus on green energy optimisation and support for circular economy initiatives, we continue to make great strides towards our Green Light Energy Goals. Net Zero demands progress with pace and precision. We will continue to drive positive change across our community of customers, suppliers and staff while maximising opportunities for growth in our ecommerce and Financial Services businesses.”
