Roadmap to Zero is a holistic Programme that supports the entire supply chain towards the use of safer and more sustainable chemistry. It is the foundation of all our work and creates the ZDHC guidelines, platforms and solutions. As the Programme expands, more guidelines and solutions are published. The work that takes place within the Programme is divided in three Focus Areas; Input, Process, and Output. Each area focussing on a particular part of a chemical product's lifecycle, as it moves across the entire manufacturing process.
