Postal operators worldwide have reduced their annual carbon emissions by 41% and launch new tool to calculate carbon footprint of cross-border online purchases 

On 17 September 2026, 23 posts worldwide take part in the 7th Green Postal Day, celebrating the contribution of posts to address climate change.

Posts have cut their overall annual emissions by over 41% 1  compared to the 2008 baseline, getting closer to their target of reaching a 50% reduction by 2030. 

To achieve this result, postal operators focused both on ensuring that electricity used in postal facilities is sourced from renewable energy and on progressively replacing the 735,000-vehicle postal fleet by alternative fuel vehicles. 

Holger Winklbauer, IPC CEO commented: “The need for action has never been greater. At the same time, customer expectations continue to rise. E-retailers and consumers increasingly expect delivery solutions that are not only fast, reliable and affordable, but also sustainable. The postal sector has been responding to these expectations for many years. Long before sustainability became a mainstream business priority, our sector recognised that meaningful progress would require collective action”.

Today, 35% of the postal fleet is composed of alternative-fuel vehicles, and 28% of the postal fleet is electric2. Hence, posts already reached their 2030 target for the electrification of their fleet, five years ahead of schedule. 38% of the electricity used in postal facilities is sourced from renewable energy3

Postal operators’ efforts are well recognised by e-retailers worldwide. According to a survey of 2,500 e-retailers in 19 countries4, 70% of them were satisfied with the sustainability performance of the postal operators.   

To provide clarity and accuracy about the carbon footprint of delivering online purchases, thirteen postal operators5, through International Post Corporation, have taken an additional step to launch the Carbon Footprint Calculator. Already 95 million parcels had their emissions measured through the Carbon Footprint Calculator

This pioneering new tool allows operators to measure end-to-end emissions at the individual item level, responding to e-retailers’ and their customers’ demand for more transparency.

The tool provides the granular data needed to understand the environmental impact of global postal shipments. It moves beyond general estimates to providing precise, item-level reporting, delivering the transparency needed to make more sustainable choices.

As more postal operators join the tool, the Carbon Footprint Calculator will become the reference for carbon footprint accounting of cross-border delivery and further reinforce postal operators’ sustainability commitment.
