What to Look for
We recommend choosing a dishwasher with the highest energy rating possible. Under the old energy labels, we would recommend “A+++”, however, with the recently updated ones, “C” is a very good score, with only one or two models on the market currently achieving “B”.
Make sure that the dishwasher is the correct size for your household to avoid running multiple small washes, it is more efficient to do one big one.
Many dishwashers now come is eco and quick wash settings which will further reduce your energy usage, helping save your bills and carbon footprint.
Finally, consider buying a second-hand dishwasher to save manufacturing emissions or look at a company upcycling appliances which helps to fight the e-waste issue, although don’t compromise on energy efficiency.
The Brand: having won the German sustainability award in 2014, Miele have often strived to put sustainability at the core of what they do.
Their 2019 sustainability report has clearly been thought through as they align with scientific targets of keeping temperatures below 2°C and consider not only their manufacturing emissions, but also the scope three emissions from the usage stage of their products.
The company is working towards carbon neutrality by 2050.
The Product: Miele appliances are definitely at the costlier end, with their dishwashers ranging from £599 – £1,499. Yet, the company are known to build products which last, reducing the carbon footprint from purchasing cheaper products more often.
Even their cheapest dishwasher features QuickPowerWash which will give clean dishes in under an hour. Their intelligent design allows for efficient loading and their water technology saves water and energy.
All but their cheapest dishwasher is rated ‘C’ for energy efficiency under the new labels. When considering the rest of the market this is currently a strong score.
The Brand: Siemens appliances are owned by Bosch, who published their “New Dimensions – Sustainability 2025” target vision in 2019. They committed to the company being climate neutral from 2020 in terms of the volume of energy it generates and purchases (scope 1 & 2). Additionally, they are aiming to reduce scope 3 emissions (“purchased goods,” “logistics,” and “use of products sold”) by 15% by 2030.
Their current path to climate neutrality involves: increasing energy efficiency; increasing the proportion of new clean power; buying in more green electricity; offsetting CO2 emissions. We were pleased to see them mention that in the future they intend to only use offset where they cannot avoid the initial emissions.
Furthermore, Bosch are getting involved in multiple projects for a greener future. These include their work on Synfuels (generated exclusively using renewable energies) for aircrafts, ships and trucks, and their blockchain technology used in the “Quartierstorm” project (a prototype for a decentralised solar market).
They are also working to reduce water consumption and pursue the principle of a circular economy.
The Product: Siemens and Bosch are two of the few companies who offer a ‘B’ rated dishwasher. Both brands offer integrated or freestanding dishwashers. Bosch’s range is slightly more affordable with more products on offer.
You can pick up a ‘C’ rated Bosch dishwasher for £699.00. If you want a more stylish design with greater smart features, Siemens offer a ‘C’ rated dishwasher for £779, which features the varioSpeed Plus, allowing you to run a cycle up to three times faster.
The Brand: The Hotpoint brand in Europe is owned by Whirlpool, a US company, who have set out some clear sustainability goals in their 2020 sustainability report. The company are aiming to reduce emissions from their products in use (scope 3) by 20% and emissions from their plants (scope 1 & 2) by 50% by 2030.
Moreover, they are aiming for a 95% reduction of high global warming potential refrigerants and foams by 2023. We would like to see them eliminate them altogether as their next goal.
They want to have zero waste going to landfill from their manufacturing sites by 2022 and will be requesting full material disclosure from 100% of their global suppliers by 2021.
Furthermore, Whirlpool have been investing in renewable energy through their first VPPA and on-site solar installations.
Whilst it is true that Whirlpool recently had a well publicised product recall on some of their washing machine models due to fires being caused, the company were efficient in recalling any product which posed a risk and none of these included their dishwashers.
The Product: Hotpoint are one of the few companies that offer a dishwasher with a rating of ‘B’ on the new energy labels, the HIP4O539WLEGTUK fully integrated standard dishwasher, which will set you back £599 and comes with a 30-minute quick wash cycle. They also offer one of the cheapest dishwashers rated ‘B’.
