(5)The technical screening criteria for economic activities that contribute substantially to climate change mitigation or climate change adaptation should ensure that the economic activity concerned has a positive impact on climate change mitigation or climate change adaptation or reduces negative impacts on such mitigation or adaptation. Those technical screening criteria should therefore refer to thresholds or performance levels that the economic activity should achieve to qualify as contributing substantially to climate change mitigation or climate change adaptation. The technical screening criteria for ‘do no significant harm’ (DNSH) should ensure that the economic activity has no significant negative environmental impacts, including climate-related impacts. Consequently, those technical screening criteria should specify the minimum requirements that the economic activity should meet to qualify as environmentally sustainable.
