Historically, from an environmental point of view, the BRICS have sometimes been marginalized and have sometimes been the victims of Western growth, but have now become major energy consumers as well as major polluters.

They have become driving forces behind new orientations and proposals, exerting their influence on North-South relations and acting as a counterweight to the prevailing model of growth.
