New research shows what many in the industry have long known - that airfreighted produce from the developing world does not necessarily have a greater impact on the environment than the same product grown in Europe.
Results from research commissioned by Sainsbury’s have shown that carbon emissions from Kenyan roses are 5.8 times lower than for roses grown in The Netherlands.
The study was carried out by Cranfield University on behalf of the retailer and World Flowers to try and establish what action the UK’s number-three supermarket needed to take in order to reduce its carbon footprint regarding the Kenyan flowers.
Sainsbury’s says the results show there is now a fresh challenge to be faced in regard to sourcing and air miles.
Environmental analysts at the university studied growing, packing, cooking and transport of roses to Hampshire including direct energy consumption, manufacture, use and delivery of fertilisers, pesticides, vehicles and materials used for buildings.
This was compared to the same inputs from a Dutch grower using artificial light and heat from fossil fuels where necessary.
“We are looking at the big picture regarding carbon emissions and the part Sainsbury’s plays in that,” said Alison Austin, head of brand policy and sustainability. “We have been extremely proactive over the last 10 years on all aspects of energy efficiency.
“The debate is now wider and we are keen to encourage suppliers to be more energy efficient as well as looking at our customer offer. What this report shows is that it is not as simple as avoiding products from far-flung places. It’s about gathering information to make an informed carbon choice.”
