An Post took home the Green Large Organisation of the Year (1000+ Employees) at the Green Awards 2026, recognised for a sustainability programme that combined measurable carbon reductions, circular economy leadership, and biodiversity restoration with a national reach that actively enables greener choices for businesses and communities across Ireland. The win sets a compelling benchmark for large-scale sustainability leadership, demonstrating how organisational scale, when backed by disciplined execution and genuine ambition, can become a powerful force for environmental progress well beyond a single organisation's own operations.
