Sustainability

People, Planet, Perfume

Conscious Luxury

Miller Harris launched 26 years ago, with a simple principle; when creating fragrances we start with nature. We strive to use ethically and sustainably sourced ingredients.

We believe we have a responsibility to be transparent and honest about our sustainability journey and performance, highlighting about our successes but also our flaws.

We will keep challenging ourselves and the brand to be better. Our ultimate goal is for our brand to operate as close to a zero environmental impact as possible.

THINGS TO BE PROUD OF

Above Certification Standard

Our Butterfly Mark accreditation stands for the highest standards of sustainability. During our last recertification in April 2024, we achieved an overall score of 68%.

We are members of the CTPA (Cosmetic, Toiletry and Perfumery Association), The Fragrance Foundation, and Walpole (official sector body for UK luxury, with a purpose of promoting, protecting and developing British luxury and championing sustainability).

We are part of a community of Real Changemakers and have held the Butterfly Certification Mark from Positive Luxury since 2018, a globally respected trust mark granted only to brands who are meeting higher and higher standards for people and nature. Our last recertification in April 2024, saw us score 68% (36% above certification standard). The certification is valid for two years.

Biodiversity

INGREDIENTS

INGREDIENTS

We source the very best natural ingredients in respect for people and biodiversity. We have full traceability on provenance and CSR actions and improvement plans.

Agricultural Practice

Agricultural Practice

Our fragrance partner works closely with local cooperatives and farmers, providing advice and training in Good Agricultural Practices, collection methods, and are taking steps to reduce the use of chemical fertilisers and pesticides.

REPLANTING

REPLANTING

In Madagascar, they plant between 10,000 and 20,000 Ylang-Ylang seedlings every year to ensure its sustainability. The Group has also left 52 hectares of protected biodiversity. Half of this area (of which 17 hectares have been designated as protected areas) will never be exploited.

Eco-cert compliance

Eco-cert compliance

Our preservatives are Eco-cert compliant, and our soaps contain Shea Butter from organic farming.
PALM OIL

Our Bath and Body products incorporate responsibly sourced (RSPO) Palm Oil derivatives.

Upon investigation we understand that, currently, this is a better option for the environment than some the alternative vegetable oils which can require up to nine times the land to produce the same amount of oil. We are however, committed to continually reviewing the landscape, engaging with the industry and with our suppliers to find even better sustainable alternatives.

Water Management

water re-use

water re-use

Our fragrance partner already re-uses water for the watering of local crops (Rose, Tuberose, Ylang Ylang) in Grasse, France but water is still needed in the final product of perfumery (the Eau de Parfum).

Monitoring

Monitoring

Our Contract Manufacturers monitor their total consumption of water per month and the consumption of water in the production processes (% water used on equipment cleaning and % water used on the production), and we are engaging with them on supplying water data relating specifically to the production of Miller Harris products.

REDUCING WASTAGE

REDUCING WASTAGE

Our main Contract Manufacturer has also switched from an internal filtration unit to purchasing water from a third-party supplier. The previous internal unit had a continual flow that flushed out regularly (resulting in uncontrolled waste). This change improved efficiencies, wastage, and traceability and resulted in a 45% reduction in usage versus the previous year.

“Each of us is part of the larger organism of human society, and just as in our bodies, each small organ must live in harmony with the others.”

Our Products & Packaging

All Miller Harris products are vegan, free from phthalates, artificial colours, parabens and formaldehydes.

They are also SLS (Sodium Lauryl Sulfate) and SLES (Sodium Laureth Sulfate) free. We use natural surfactants. Our Natural Raw materials are all from a sustainable supply chain.

Our approach to all packaging is “the bare minimum” and a circular economy. We challenge ourselves to produce items that can have an after-life.

Reduce Design using minimum amount of material for each component.
Recycle Design for better recycling, avoiding shrink sleeving and multi-material designs.
Re-use Design for re-usability, by improving the longevity.

  • Home

    Our candle and diffuser range has been re-designed to significantly lessen the impact on the environment with fully re-usable or recyclable vessels.

    The wax bases for candles are made from soy and rapeseed wax sourced from the UK, whilst our diffusers use organic alcohol, from sustainable sources.

  • Fragrance

    Our EDP collection bottles are not currently recyclable due to the crimped neck and pump.

    Historically the main reason for the use of crimped pumps within the industry was to better protect against leakage.

    We are working with our suppliers on the development of a screw neck bottle for our core range, which will enable our bottles to be refilled. This will take time and thorough testing, but we are fully committed to the changeover.

  • Bath & Body

    Our recyclable bottles are made from 100% PCR (Post-Consumer Recycled) plastic which is lighter in weight than glass and therefore less impactful on the environment to transport. Using PCR means we don’t need to manufacture new plastics.

    Our Hand Cream tubes are made from infinitely recyclable aluminium.

    All of our caps are are made of recyclable Poly Propylene.

    Our Bath & Body pumps are recyclable even though they contain a stainless steel spring.

INGREDIENTS

M.H Upcycled

20% of our Eau de Parfums now contain at least one upcycled material.


The production and control of natural materials for use in perfumery is at a crucial juncture in its history. We have a responsibility to look at the waste and biproducts within the manufacturing process.
