The supermarket supplier said the investment will result in an estimated 12% carbon reduction by the company over a two-year period.

Noel Keeley, CEO of Musgrave Group, said: “Climate change is the single biggest problem that we face as a society. We have a very strong track record when it comes to sustainability, and as part of our new sustainability strategy we are investing €25 million to reduce the carbon footprint of our independent retail Centra and SuperValu stores all over the country by 12%.”

Mr Keeley said the company can see the contribution that replacing less efficient equipment with more efficient equipment makes.

“We can also see how much green energy we are generating as opposed to traditional energy. So it’s quite measurable. It’s equivalent to planting 400,000 trees or enough power to power 5,000,” he said.

Musgrave is committing up to €50,000 per SuperValu store and up to €28,000 per Centra store. Retailers can select suitable initiatives based on each store’s needs, including upgrading freezers and refrigeration units, LED lighting retrofit, solar panels, and electronic shelf edge labels.

The group CEO said its suppliers are also making similar sustainable changes.

“We work hand in hand with our suppliers to make sure we are all doing our part because ultimately we can only achieve these outcomes by the whole supply chain cooperating together,” he said.

Musgrave’s new sustainability strategy will also provide consumers with more sustainable shopping choices in-store.

It said it is committed to 100% of its own brand packaging recyclable, reusable or compostable by 2025; 100% of produce packaging to be recyclable, reusable & compostable by 2025; and 100% of instore packaging to be recyclable, reusable & compostable by 2025.

Mr Keeley said Musgrave is also looking at sourcing products closer to home to avoid the cost and environmental impact of shipping.

“Musgrave would be very proud of the fact that we source 75% of our products on the island of Ireland already, so will absolutely and always have been focused on reducing food miles.”
