Natural England launched the Green Infrastructure Framework: Principles and Standards for England in January 2023. During the course of developing the Framework they produced and commissioned research, working with government Departments for: Environment Food and Rural Affairs; Levelling Up, Housing and Communities; Transport and Health and Social Care. They also sought wider from input from experts in public bodies and private organisations to steer and advise. Natural England and Public Health England (Office for Health Improvement and Disparities) published a Rapid Scoping Review of Health and Wellbeing Evidence as part of the project. In addition, Defra has also funded research into the economic modelling of accessible green space across England and Wales, known as the Outdoor Recreation Valuation tool. As set out in the Environmental Improvement Plan 2023, we will use the Green Infrastructure Framework to track progress in our commitment for everyone to have access to green or blue space within 15 minutes from their front door
