Unilever, a leading manufacturer of cleaning and laundry products, on September 2, 2020, 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.
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.
Clean Home. Clean Planet. Clean Future
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, EUR 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 Rainbow
Central 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.
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.”

Unilever’s existing sustainability commitments
Today’s ambition to replace 100 % of the carbon derived from fossil fuels in Unilever’s Home Care formulations with renewable or recycled carbon by 2030, builds on Unilever’s existing environmental commitments, including:
- Ensuring net-zero carbon emissions from all its products from cradle to shelf by 2039
- Achieving a deforestation-free supply chain by 2023 Halving the GHG footprint of its products across the value chain by 2030.
- Zero greenhouse gas emissions from its own operations by 2030.
- Aiming to make its product formulations biodegradable by 2030
- Halve its use of virgin plastic, help collect and process more plastic than it sells, ensure all of its plastic packaging is reusable, recyclable or compostable by 2025, and use at least 25% recycled plastic in its packaging, also by 2025.
Renewable and recycled carbon
Renewable and recycled carbon entails all carbon sources that replace the use of fossil carbon from the geosphere. Renewable carbon can come from the biosphere and atmosphere. Recycled carbon comes from the technosphere. Renewable and recycled carbon circulates between biosphere, atmosphere and technosphere, creating a circular carbon economy.
The Carbon Rainbow in practice
The Clean Future programme is already funding research & development into projects such as:
- Purple carbon (carbon capture and utilisation to produce soda ash and other chemicals)
- Green carbon (rhamnolipids surfactant derived from terrestrial biomass)
- Grey carbon (surfactant derived from plastic waste)
- Biodegradability (biodegradable cleaning polymers)
- Low-carbon formulations (weight-efficient ingredients)
