Design for environment
Definition
Design for environment (DfE) is a design methodology that integrates environmental considerations into product and process development from the earliest stages, using life-cycle thinking and tools such as life-cycle assessment. It is functionally interchangeable with ecodesign, which ISO 14006:2020 defines as a systematic approach that considers environmental aspects in design and development to reduce adverse impacts throughout a product's life cycle. An estimated 80 per cent of product-related environmental impacts are determined at the design phase.

Overview
What it means
Environmental performance treated as an engineering requirement alongside cost and reliability — locked in at the drawing board, not bolted on later.
How it is used
DfE guides material selection, lightweighting, disassembly, recyclability and energy efficiency; the EU Ecodesign for Sustainable Products Regulation (in force 18 July 2024) turns many DfE principles into law.
Why it matters
Most footprint reduction potential is decided during design; DfE is the discipline that captures it before options close.
