Health and environment. There is a host of health and environmental benefits attached to the Net Zero transition. More walking and cycling and less carbon-intensive diets can improve health, as can cleaner air and better insulated homes (e.g. the annual cost to the NHS of poor-quality housing in England alone has been estimated at over £1 billion).+ Restoration of peatlands and planting of woodlands can improve access to green space and, done well, can provide new income streams for farmers, improve the natural environment, support biodiversity and improve adaptation to the impacts of climate change. Scotland, Wales and Northem Ireland together cover a fifth of UK emissions. They have an integral role to play in delivering the UK's Sixth Carbon Budget on the path to Net Zero. For Scotland and Wales, this will be achieved under long-term targets passed in Holyrood and the Senedd Cymru. Northern Ireland is considering introducing its own climate legislation.
