Textiles such as clothing and shoes are the most environmentally-damaging type of household waste in Scotland, according to a new study.
Zero Waste Scotland’s carbon metric report tracks the full lifecycle impact of items thrown away by Scottish homes.
It found textiles were just 4% of what was binned in 2021, in terms of weight, but accounted for 32% of the carbon footprint generated by household waste.
The environmental body said Scots “need to rethink our consumption of goods”.
The report looked at the emissions generated by the products Scottish households consume and then throw away.

This included the extraction of the raw materials which make up those products and the manufacturing of them – processes which often happen abroad. It also looked at the emissions from the disposal of household waste items through landfill or incineration.
The textiles category included clothing, shoes and carpets – with clothes and shoes accounting for about 80%.
Zero Waste Scotland said that the clothing we buy is often produced via long supply chains which generate large volumes of greenhouse gas emissions at every stage.
This might include the production of the yarn or the fabric and then the manufacture of the finished product, such as washing and dying. Each of these steps will create greenhouse gases in the country of production.
There was a slight overall increase in the total carbon footprint of Scottish household waste, rising by 0.9% on last year.
Zero Waste Scotland said the increase in textile waste was the main contributor to this.
Food waste was the second highest contributor to the carbon impact of household waste – making up 30% of greenhouse gas emissions, but only 18% of household waste by weight.
Iain Gulland, chief executive of Zero Waste Scotland, said: “If we’re serious about tackling climate change we need to rethink our consumption of goods and materials.
“The average Scot consumes more than twice the sustainable amount of materials per year, and our throwaway culture encourages that approach. It’s an environmental imperative that we turn this around.”
The Scottish government funded agency is encouraging Scots to “do things differently” and look to the circular economy model – where people are encouraged to reuse, donate and recycle products.
Mr Gulland added: “The circular economy gives us the opportunity do things differently without compromising on quality of life, evolving an economy that’s better for both people and planet in which goods and materials are valued and made to last.”
