In 2008, Omya embarked on a partnership with The Natural Step and adopted a new sustainability framework inspired by their four system conditions of a sustainable society:
In a sustainable society, nature is not subject to systematically increasing…
… concentrations of harmful substances extracted from the Earth's crust;
… concentrations of substances produced by society;
… degradation by physical means;
And in society…
…people are not subject to conditions that systematically undermine their capacity to meet their needs.
