Natural England has published the National Green Infrastructure Framework, a commitment in the government’s 25 Year Environment Plan. It is designed to help local planning authorities and developers in England meet requirements in the National Planning Policy Framework to consider green infrastructure in local plans and in new developments. The Green Infrastructure Framework comprises:

• Green Infrastructure Principles: the what and how of good green infrastructure.
• Green Infrastructure Standards: guidance on national standards for green infrastructure quantity and quality.
• Green Infrastructure Maps: mapped environmental, socio-economic datasets to support the standards.
• Green Infrastructure Planning and Design Guide: practical, evidence-based advice on how to design good quality green infrastructure.
• Green Infrastructure Process Journeys: guides on how to apply all the products in the Green Infrastructure Framework.

The Institute of Civil Engineers has published the ICE Manual of Blue-Green Infrastructure. It is a complete practical reference to Blue-Green Infrastructure (BGI) solutions for practitioners, and provides guidance on key considerations in BGI design, creation, retrofitting and maintenance.
