Environment Bill — House of Lords, 2021-06-21
Topic: Environment
Rupert Carington (Crossbench, Unknown): My Lords, I would like to speak in favour of Amendment 10 in the names of the noble Lords, Lord Randall and Lord Taylor. The effect of light pollution is intrinsically part of the existing four priority areas for which environmental targets will be set, but it is not mentioned in any of the actions identified in the Bill to remedy or mitigate the underlying issues raised by these targets. Hence a separate target to reduce levels of light pollution is necessary and will not be difficult to implement or measure I declare my interest, being a vice-chair of the APPG on Dark Skies, like the noble Lord, Lord Taylor of Holbeach, and as the grandson of a knighted astronomer. Light pollution is relevant to human health, nature and wildlife, energy consumption and thereby greenhouse gas emissions. First, on health, epidemiological studies conducted in the United States have identified poorer sleep and anxiety disorders emanating from outdoor illumination, affected physical and mental health and well-being. Constant light is a well-known method of torture. Secondly, there is the effect on nature and wildlife. A review from Nature magazine in 2018 concluded that "early results suggest that light at night is exerting pervasive, long-term stress on ecosystems, from coasts to farmland" and "waterways, many of which are already suffering from other, more well-known forms of pollution." The article then mentions a UK study on the timing of bud opening in trees, also raised by the noble Lord, Lord Randall. The study demonstrated a rate of acceleration "similar to that" now "predicted for … global warming" A Defra report in 2019 showed a sharp decline in insect numbers, with a 31% drop in insect pollinators between 1980 and 2016, and a 60% decline in the 2,890 priority species from 1970 to 2016. The State of Nature 2019 report by the National Biodiversity Network identified urban areas as particularly affected. In 2017, a paper from Nature highlighted the connection between light pollution and pollinating insect species, suggesting a threat to world food production Thirdly, there is the additional and unnecessary fuel consumption associated with aggressive illumination and the extra burden on greenhouse gas emissions. The reason for illumination that is so often given is that of safety. A study by the London School of Hygiene & Tropical Medicine found that crime and road collisions do not increase in dark or dimmed areas. Measuring light pollution is simple, as mentioned by the noble Lord, Lord Randall, with the use of a system produced by CPRE that can form the basis of monitoring change. Let us use this opportunity to acknowledge and deal with this important area, as encouraged by the Government’s draft environmental principles, encompassing both precaution and prevention. Measures to remedy the problems are not rocket science but clearly achievable through the strengthening of the planning framework, the reform of planning permission processes, the strengthening of statutory nuisance provisions, education, and technological developments. We can also learn from examples of measures taken in countries such as France and Germany Surely the amendment has a necessary and worthy place in this important Bill.
