The ZDHC MMCF Guidelines V3.0 have been restructured to align with the ZDHC framework of input, process and output management, bringing consistency across sectors. 

One of the key updates includes the revision of sulphur (S) air emissions limits to align with the EU Best Available Techniques (BAT)  requirements. 

The guidelines now also require sludge testing and reporting of disposal pathways. 

Wastewater parameters have been revised to better align with the general ZDHC Wastewater and Sludge Guidelines for textile, leather and footwear sectors.

Additionally, now facilities are expected to report Scope 1 and Scope 2 GHG, promoting greater environmental transparency and accountability.
