Guinness has announced plans to introduce the first zero emission vehicles into its fleet from this summer.
The company is aiming for 70% of its fleet to be zero emission by the end of 2025, and 100% by the end of the decade.
Guinness already has a zero emission vehicle, which is used exclusively at the brewery.
This week it is being used in a trial to transport bulk beer in the Guinness tankers from St James's Gate to Dublin Port, which will help determine if it can be used to transport heavy goods beyond the brewery.
Guinness also plans to add four zero emission trucks later this year to its fleet which will be used in a separate trial to deliver kegs to the hospitality trade in Dublin City, with an ambition to extend further if successful.
Barry O'Sullivan, Managing Director of Diageo Ireland, said the company was committed to reducing its indirect emissions through this initiative,
He said the company wants to play a key role for sustainable transport in the commercial sector in Ireland.
"We are only 263 years into our 9,000-year lease on the St James’s Gate Brewery, and we are in it for the long haul - for our people, our products and our planet, and we will never settle in pursuit of a better, more sustainable future for everyone," Mr O'Sullivan said.
Today's announcement forms part of Diageo's wider 10-year sustainability action plan, Society 2030: Spirit of Progress, which outlines the company’s commitment to delivering net zero carbon emissions across its direct operations and a reduction in indirect emissions by 50%.
