My Lords, with the amendments in this group being supported all around the Committee, it suggests to me that there is a strong opinion that the Bill should not be so silent on green spaces. My Amendment 121 seeks to make it mandatory that provision for green space must be included in any application for new housing developments. It does not seek to be prescriptive as to the type of green space but leaves that open to community consultation. Noble Lords will be aware that the revised National Planning Policy Framework recognises that green space is important, and it includes in its golden rules, where it refers to “the provision of new, or improvements to existing, green spaces that are accessible to the public”. Where residential development is involved, the objective is that: “New residents should be able to access good quality green spaces within a short walk of their home, whether through onsite provision or through access to offsite spaces”. The problem with that is that the wording is rather vague, and the green space is only an objective, not a requirement. At worst, that requirement could be fulfilled through off-site provision. We must learn from past developments and ensure green space provision is integral to the developments. It must be there at master-plan stage. Let us look at some of the advantages, which I am sure noble Lords are very aware of. The BBC suggests that approximately 28% of people live more than a 15-minute walk from their nearest public park, and the Green Space Index reports that 6.1 million people have no park or green space within a 10 or 15-minute walk. The thing is that a 10 or 15-minute walk with a couple of toddlers or for an elderly person is a round trip of 30 or 40 minutes. Later in the Bill, we will get to the issue of mitigation, so I will not discuss that here except to point out that, if local delivery of mitigation is prioritised, then high-quality, nature-rich green spaces will be baked into the plans. These are all positive things that we need to look at. There is the boosting of mental health and overall well-being. A long-term study by the University of Exeter found that living in greener areas significantly reduces mental distress and increases life satisfaction. I am sure we can all remember the disparity in access to green space during the Covid-19 lockdowns, particularly for those without gardens. It really became starkly clear, and it really intensified the public’s demand that parks are valued, because people suddenly really realised the value of their local park, be it big or small. Then, of course, there is tackling physical inactivity. Proximity to parks and open spaces encourages physical activity. People living within 500 metres of green areas are more likely to take at least 30 minutes of daily exercise, and it has been estimated that access to quality green and blue spaces in England could save £2.1 billion a year in health costs—and that is before we get on to the environmental benefits. Green space—trees, grass—is involved in carbon sequestration and air quality issues. Trees, shrubs and grasslands absorb CO₂, acting as carbon sinks. The vegetation filters out air pollutants—for example, particulate matter—which is important with respect to ozone in urban areas. It improves urban air quality, again reducing health burdens. Green spaces tend to reduce the local temperature when it is hot in summer through shading, and cooler microclimates lessen reliance on energy-intensive air conditioning, cutting emissions from electricity use. Green spaces are win-win in every way. Noble Lords have just been talking about flood risk reduction and water management; green spaces, with their permeable soils, vegetation and sustainable urban drainage, absorb rainwater and reduce runoff. During the debate we have just had on water management, we did not mention, for example, the city of Philadelphia, which had a very similar issue to the one that we in London have solved through the Thames tunnel. In Philadelphia, they solved it by creating masses of green space; they spent less money, yet they have the win-win situation already. That is a lot of advantages, without mentioning the biodiversity and ecosystem services that we can get through those plantings. Strategically planted trees provide shading in summer, which I have mentioned, and wind protection in winter, improving thermal comfort for people in those areas. Masses of research and dozens of statistics make the case for accessible, quality green space. I have read a lot of this research in the papers, but I make this case because of the sheer joy and relaxation that I personally experience from a walk in the park, whether here in London or at home in Devon. I want to ensure that that is our contribution to this Bill. I certainly support the other amendments in this group from, for example, the noble Lords, Lord Teverson and Lord Gascoigne, who are right to put green into spatial strategies. I have also added my name to the amendment from the noble Baroness, Lady Bennett of Manor Castle, on allotments and community gardens, which are particularly special green spaces and great promoters of community cohesion, but I will resist going on about that as I am looking forward to hearing from the noble Baroness, Lady Bennett. The final two amendments in this group seek to give development corporations a duty to provide green space—again, an extremely correct ambition. The Government must see that there is a lacuna in the Bill, as nowhere does it place any mandatory duty for the provision of green space as an essential. It is not—and should not be regarded as—an optional extra. Given the large number of Peers who have tabled amendments on this issue, I hope that the Minister will bring forward some constructive wording before Report to fulfil the aspiration all around the House. I beg to move.
