Environmental concerns

An oil's sustainability depends on the way it is produced.

Sunflower and rapeseed oils made outside Europe and the UK are sprayed with neonicotinoids and insecticides implicated in killing bees, butterflies, moths and other insects. As a result, they are now banned in Europe and the UK. 

Oils made from crops known to cause environmental damage, such as avocado and soy (deforestation), and almonds (water requirements, insecticide use), might not be a green choice either.
