For climate change adaptation, regulators were required to assess possible climate impacts in four areas: human health, infrastructure and location, land use, landscape, ecosystems and biodiversity, and water resources. The presumption was that the most climate-friendly alternative would be selected. Legislative texts were required to include a statement on the climate relevance of the act and alternatives considered, and, if the alternative chosen was not the most climate-friendly among those considered, a short statement of justification.
