The Dutch grower has been cultivating in accordance with the criteria of the Milieukeur Foundation for several years.
A Milieukeur representative said: "These criteria amply comply with the norms set by government and other authorities with regard to sustainable production and purchasing. All available trees and shrubs on [Van den Berk] plots are eligible for the Milieukeur certificate.
"This makes Van den Berk Nurseries one of the largest companies with sustainably and environmentally produced trees and shrubs in Europe."
The standard covers multiple environmental/social attributes and the full life-cycle phase, and audit certification holders are audited every year by an independent third party.
