The core element of the Input Focus Area (and the Roadmap to Zero Programme) is the ZDHC Manufacturing Restricted Substances List (MRSL). Additional elements that support the ZDHC MRSL and that further ensure safe chemical inputs are:

1. the ZDHC Conformance Guidance
2. the ZDHC Industry Standard Implementation Approach
3. the ZDHC Performance InCheck Guidelines
4. the ZDHC Gateway - Chemical Module
