Artificial light offers valuable benefits for safety and amenity. Defra has worked with the Department for Levelling Up, Housing and Communities to ensure that the National Planning Policy Framework is clear that policies and decisions should limit the impact of light pollution on local amenity, dark landscapes and nature conservation. Our National Parks and Areas of Outstanding Natural Beauty have some of the best dark skies across Great Britain and attained some of the earliest designations in Europe. Seven of our parks have secured protected dark sky status and we are committed to conserving and celebrating this wonderful experience for all.

Defra has funded or co-funded national and international assessments of drivers of change on insects and wider biodiversity such as the global IPBES Assessment Report on Pollinators, Pollination and Food Production. This report notes the effects of artificial light in general on nocturnal insects may be growing.

HM Government has not made any specific assessment of the impacts of light pollution or changes in spectrum on insect population trends. We will continue to work closely with researchers, NGOs and across HM Government to improve our understanding of the impacts of light pollution

Protecting insects is a priority, and we are taking action to support them and the wider natural environment of which they are a vital component. Our legally binding target to halt the decline in species abundance by 2030 underlines our ambition.
