In Ireland, Diageo announced plans to invest over €100 million to decarbonize its historic St. James’s Gate site in Dublin 8, where Guinness has been brewed for 264 years. The investment underpins the goal to accelerate to net zero carbon emissions for the site and will transform energy and water consumption with the aim to make it one of the most efficient breweries in the world by 2030.

By 2030, the site’s renewable energy strategy will combine the use of grid-supplied electrical power heat pumps; and biogas generated within a new water recovery facility. This facility will also improve water use efficiency and enable a projected reduction in the water used to brew Guinness by 30%.
