Our Materials Impact our Climate
(November 2021 COP 26 statement from the leather industry. Hopefully more leather bodies will publicly align with this statement and promote it in the next weeks and months, and build on it as we look forward to COP27 and beyond)
The world needs materials that are sustainable, renewable, recyclable, biodegradable, and most importantly, do not add to the burden of atmospheric carbon.
Natural fibres, such as leather, cotton, wool, mohair, alpaca, silk, hemp and mycelium, are part of the biogenic carbon cycle and as such are comprised of carbon that has been in the atmosphere for a millennia.
These readily available raw materials, when ethically and properly produced, are an important replacement for fossil fuels, reducing the need for its extraction and retaining more carbon in the earth.
Furthermore, at the end of life, properly produced natural materials will biodegrade, limiting their impact and mitigating harmful emissions, such as microplastic pollution, often associated with the synthetic materials that they replace.
With particular reference to leather, the leather manufacturing sector upcycles an unavoidable waste from the food industry, to produce a versatile, durable, unique material, ideal for the circular economy that the world must move towards.
However, these same materials are often dismissed through a lack of understanding of the manufacturing process and its supply chain, or through the application of questionable science generally in the form of incomplete and incomparable or out-dated Life Cycle Assessments (LCAs), and the marketing of new, often fossil fuel-based materials claiming unsubstantiated levels of sustainability.
As shown by some emerging climate science studies, such as the GWP* model, production and use of biogenic materials typically does not add to the warming burden of the atmosphere, and where it does, the effects are short-lived. This is in contrast to materials produced from fossil-fuels, which release carbon that has been locked in the earth’s core for a millennia, and will persist in the environment, contributing to climate change.
Therefore, we, the undersigned organisations, call on the COP26 forum to…
…Recognise the cyclical, climate efficient nature of natural fibres and their potential for a positive contribution to reducing the climate impacts of consumer products.
…Encourage the use of natural fibres wherever feasible and reduce unnecessary reliance on fossil-fuel-based materials.
…Support LCA methodologies that accurately account for the environmental impact of fossil-fuel based materials, including end of life properties.
…Promote ‘slow fashion’, durable products, and items that can be used many times, repaired and refurbished, and last for years.
