Unilever, a leading manufacturer of cleaning and laundry products, today announces it will source 100% of the carbon derived from fossil fuels in its cleaning and laundry product formulations with renewable or recycled carbon. This move is set to transform the sustainability of global cleaning and laundry brands including Omo (Persil), Sunlight, Cif and Domestos.
This new ambition is a core component of Unilever’s ‘Clean Future’, a ground-breaking innovation programme designed by the company’s Home Care division to fundamentally change the way that some of the world’s best known cleaning and laundry products are created, manufactured and packaged. Clean Future is unique in its intent to embed the circular economy principles into both packaging and product formulations at the scale of global brands to reduce their carbon footprint.
Most cleaning and laundry products available today contain chemicals made from fossil fuel feedstocks, a non-renewable source of carbon. Unilever’s move to renewable or recycled sources of carbon for these chemicals is a deliberate shift away from the fossil fuel economy. The first initiative of its scale, Clean Future is a critical step towards Unilever’s pledge of net zero emissions from its products by 2039.
The chemicals used in Unilever’s cleaning and laundry products make up the greatest proportion of their carbon footprint (46%) across their lifecycle. Therefore, by transitioning away from fossil fuel-derived chemicals in product formulations, the company will unlock novel ways of reducing the carbon footprint of some of the world’s biggest cleaning and laundry brands. Unilever expects this initiative alone to reduce the carbon footprint of the product formulations by up to 20%.
Peter ter Kulve, Unilever’s President of Home Care, explains: “Clean Future is our vision to radically overhaul our business. As an industry, we must break our dependence on fossil fuels, including as a raw material for our products. We must stop pumping carbon from under the ground when there is ample carbon on and above the ground if we can learn to utilise it at scale.
“We’ve seen unprecedented demand for our cleaning products in recent months and we are incredibly proud to play our part, helping to keep people safe in the fight against Covid-19. But that should not be a reason for complacency. We cannot let ourselves become distracted from the environmental crises that our world – our home – is facing. Pollution. Destruction of natural habitats. The climate emergency. This is the home we share, and we have a responsibility to protect it.”
Unilever is ring-fencing €1 billion for Clean Future to finance biotechnology research, CO2 and waste utilisation, and low carbon chemistry – which will drive the transition away from fossil fuel derived chemicals. This investment will also be used to create biodegradable and water-efficient product formulations, to halve the use of virgin plastic by 2025, and support the development of brand communications that make these technologies appealing to consumers. The Clean Future investment, which is additional to Unilever’s new €1 billion ‘Climate and Nature fund’, is focused on creating affordable cleaning and laundry products that deliver superior cleaning results with a significantly lower environmental impact.
Clean Future already supports industry-leading projects around the world to transform how the chemicals in Unilever’s cleaning and laundry products are made. In Slovakia, for instance, Unilever is partnering with biotechnology leader Evonik Industries to develop the production of rhamnolipids, a renewable and biodegradable surfactant which is already used in its Sunlight dishwashing liquid in Chile and Vietnam. In Tuticorin in Southern India, Unilever is sourcing soda ash – an ingredient in laundry powders – made using a pioneering CO2 capture technology. The soda ash is made with the CO2 emissions from the energy used in the production process. Both technologies are hoped to be scaled significantly under the programme.
The Carbon RainbowCentral to Clean Future is Unilever’s ‘Carbon Rainbow’, a novel approach to diversify the carbon used in its product formulations. Non-renewable fossil sources of carbon (identified in the Carbon Rainbow as black carbon) will be replaced using captured CO2 (purple carbon), plants and biological sources (green carbon), marine sources such as algae (blue carbon), and carbon recovered from waste materials (grey carbon). The sourcing of carbon under the Carbon Rainbow will be governed and informed by environmental impact assessments and work with Unilever’s industry-leading sustainable sourcing programmes to prevent unintended pressures on land use.
This diagram is an illustration of Unilever’s trademarked Carbon Rainbow. The rainbow shows how Unilever is eliminating fossil fuels in its cleaning products by 2030, by replacing this with four new sources of carbon. These are represented by a rainbow with four colours: purple to represent carbon from CO2 (including from industrial emissions); blue represents carbon from marine sources; green represents carbon from plants; and grey represents carbon from plastic waste.
These renewable sources of carbon are processed into useful ingredients to produce cleaning and laundry products. After the consumer uses the product and disposes of it, the formulation biodegrades and plastic waste is chemically recycled. This creates carbon to produce new consumer products, and so the Carbon Rainbow cycle continues. All of this is powered by renewable energy, which sits at the middle of this circular illustration.
Tanya Steele, Chief Executive of WWF UK says: “The world must shift away from fossil fuels towards renewable resources that reduce pressure on our fragile ecosystems and that help to restore nature. These significant commitments from Unilever, combined with strong sustainable sourcing, have real potential to make an important contribution as we transition to an economy that works with nature, not against it.”
Peter ter Kulve, Unilever’s President of Home Care, concludes: “A new bioeconomy is rising from the ashes of fossil fuels.
“We’ve heard time and time again that people want more affordable sustainable products that are just as good as conventional ones. Rapid developments in science and technology are allowing us to do this, with the promise of exciting new benefits for the people who use our products, from ultra-mild cleaning ingredients to self-cleaning clothes and surfaces.
“Diversifying sources of carbon is essential to grow within the limits of our planet. Our suppliers and innovation partners play a critical role through this transition. By sharing our Carbon Rainbow model, we are calling on an economy-wide transformation in how we all use carbon.”
