(45)The technical screening criteria should ensure that relevant economic activities within a specific sector can qualify as environmentally sustainable and are treated equally if they contribute equally to one or more of the environmental objectives laid down in this Regulation. The potential capacity to contribute to those environmental objectives can vary across sectors, which should be reflected in those criteria. However, within each sector, those criteria should not unfairly disadvantage certain economic activities over others if the former contribute to the environmental objectives to the same extent as the latter.
