Animal fats partly used in sustainable aviation fuel raises climate concerns, study reveals


Growing demand for animal fats biofuels to power Europe’s transport system raises concerns over climate impacts and potential fraud, Transport & Environment (T&E) revealed in a study.

Rendered animal fats are a by-product of industrial meat production and have a number of surprising and less surprising uses. Most notably animal fats have been used so far in pet food and in the oleochemicals (e.g. soap, cosmetics) industries.

Less well known, however, is their use as transport fuels, currently mostly in cars and trucks. Major airlines have recently struck big deals with oil suppliers for what are termed ‘sustainable aviation fuels’ (SAF). Even if the detail of the exact feedstocks used in SAFs is mostly vague, they often include animal fats.

As the study carried out by Cerulogy on behalf of T&E shows, there is already significant pressure on supplies of animal fat as its use in biodiesel has grown forty fold since 2006.

Transport & Environment (T&E) is a European umbrella for non-governmental organisations working in the field of transport and the environment, promoting sustainable transport in Europe; which means an approach to transport that is environmentally responsible, economically sound and socially just.
