CO2-neutral in goods transport too
A large proportion of CO2 emissions comes from goods transportation. We are reducing its environmental impact by using alternative fuels such as biodiesel and hydrogen and by transporting goods by rail. In addition, we are steadily reducing a portion of CO2 emissions through sophisticated offsetting projects.
Our extensive POS network requires distribution by truck, but we already rely on rail for over two thirds of our goods transportation between our national and regional distribution centres.
More rail in preference to road
Since 2011, we have used the unaccompanied combined transport (UCT) concept to shift more of our goods transportation to rail. This involves transporting the goods to the nearest rail hub in swap bodies and transferring them to trains. The freight containers are transported from the destination rail hub to the points of sale by road. This form of transport is even possible for smaller journeys of up to around 90 kilometres.
In our City Cargo Geneva project, for instance, the foods are transported from the distribution centre in Aclens directly to the centre of Geneva. This has a positive effect on the climate and reduces traffic on the motorways. Since 2014, basic foods and wine from Italy have also been transported from Chiasso to our distribution centres by Railcare, using UCT. The environmentally friendly combination of road and rail enables us to transport around 3,000 additional swap bodies each year.
Biodiesel and biogas as fuels
To reduce the CO2 emissions caused when transporting goods by truck, we are increasingly relying on fuel from biogenic waste. We have already converted our filling stations at the distribution centres, where drivers fill their trucks with up to 20 percent biodiesel produced from organic waste such as used cooking oil. Our new trucks all meet the Euro 6 emissions standard and can be run entirely on biodiesel. On average, our trucks are 30 percent fuelled by biodiesel.
Transport by electric truck
Switzerland's first 18 tonne electric truck, which is both quiet and energy-efficient, supplies our supermarkets in the greater Zurich area without causing any CO2 emissions. The electric truck is powered by electricity from hydrogen obtained from the grid and by solar power from a photovoltaic unit on the roof of the vehicle. At 1 kilowatt hour of electricity per kilometre, it requires only around a third as much energy as a conventional diesel truck. Based on our very positive experiences of the project, we began using six additional electric trucks in 2016.
Mobility in the closed hydrological cycle
Research has been conducted on CO2-free vehicles for years. Together with a number of partners in the fields of politics, science, business and administration, Coop has built up the overall hydrogen system and thus created the prerequisites for the most sustainable form of electric mobility. The generation of renewable electricity forms the basis of sustainably produced hydrogen. The hydrogen for Coop Mineraloel AG's filling station in Hunzenschwil is produced at IBAarau's run-of-the-river power plant. Only sustainably produced surplus power is used to produce hydrogen, i.e. electricity that would not otherwise be used. This new kind of mobility emits no CO2, no nitrogen or sulphur oxide and no soot particulates. Ultimately, only steam is emitted from the exhaust and subsequently falls back to the ground as precipitation. In addition to twelve company cars, Coop has a hydrogen-fuelled truck – itself a world first. Compared with a conventional truck, it causes 70 to 80 tonnes less CO2 each year.
New carbon delivery truck
In 2015, we began using a new Coop@home delivery vehicle – the world's first 3.5 tonne delivery vehicle of carbon construction. Its tare weight is around 400 kilos less than all previous Coop@home delivery trucks and its maximum load of 1.5 tonnes is over a third greater. The result: more deliveries can be made to customers on each tour, fuel consumption is lower and CO2 emissions per tonne-kilometre are roughly 30 percent less.
Reduction of air freight
Besides goods transport within Switzerland, air freight from overseas also damages the environment. Our internal guidelines state that air freight may only be used if, for reasons of quality or very tight time constraints, there is no other option. We label goods that have been flown in with a By Air sticker. Thanks to faster logistics processes and modern refrigeration techniques, it is possible to transport more and more goods from overseas by boat.
Comprehensive CO2 offsetting concept
Since 2007, we have offset each air mile of our goods transport as well as all our business trips. We also offset the CO2 emissions from deliveries by our online store Coop@home. To do this, within our value chains and working with the WWF, we are devising projects according to the Gold standard, the most stringent existing standard for climate protection projects. As well as protecting the climate, these projects must also benefit the local population. To give one example, the construction of biogas plants in one of our rice growing areas in India reduces CO2 emissions by around 5 tonnes per plant and per year.
The provision of efficient ovens in our rose-growing region in Kenya has also helped reduce CO2 emissions. Thanks to the ovens, the local people need to collect and burn less firewood, cutting firewood consumption in half. The lessening of harmful smoke indoors also has a positive impact on the health of the occupants. The Coop Sustainability Fund carefully finances selected offsetting projects, providing around 2 million Swiss francs a year.
