The ZDHC Air Emissions Guidelines V1.0 directly follows on from the Air Emissions Position Paper, which was first published in 2019. The limits and recommendations shared in the Air Emissions Position Paper gave direction to the industry, where there is no existing harmonised standard for air emissions across the industry.

Transitioning the Air Emissions Position Paper into guidelines requires a step-by-step approach. That approach first creates awareness by helping facilities to identify and understand the types of emission sources and pollutants that are emitted. The second step moves further into tracking and reporting emissions of key pollutants associated with facility operations and production, followed by adoption and implementation of Best Available Technologies (BAT), including equipment and processes, to minimise air emissions.

These documents complement one another in highlighting the connection between air emissions and chemical input to the industry, and working to improve air quality through better input chemistry.
