Costa Coffee is to source its entire coffee supply from sustainable farms.

From September 2008, at least 30% of the coffee used in Costa’s Mocha Italia blend – which forms the base of its coffee drinks – will come from Rainforest Alliance certified sources. It will then gradually work towards a 100% sustainable sourcing policy.Costa’s marketing director David Hutchinson said: “We know that it will take time to convert our supply base to certified sustainable sources, but we believe it’s an investment that is right for our business, right for the coffee industry as a whole and we believe it’s a journey our customers will want to be part of.”

Farms must meet rigorous standards to gain Rainforest Alliance accreditation, including reducing pesticide use, improving worker safety and protecting forests and soil.

The Rainforest Alliance is a not-for-profit non-governmental organisation that works to conserve biodiversity and ensure sustainable livelihoods by transforming land-use practices, business practices and consumer behaviour.
