Legal systems play an important governance role in facilitating responses to climate change across all levels of society  . Laws can facilitate climate action in multiple ways, including through:  mandating and guiding the behaviour of governance structures and actors,  fostering coordination between different levels of government,  enforcing climate responses,  its symbolic value and  aligning scientific evidence and societal norms . Laws also can embed climate change planning within the administrative structure of a state, rendering policy less vulnerable to revocation . Extensive revision to laws has occurred in the last decade: a survey of 164 countries showed that over 1200 climate-related national laws and policies have been published, with approximately 44% being acts of parliament .
