# Harms and Benefits

### Project Developers Must 

* Show that feedstock production, biomass conversion, and carbon disposal operations have a low risk of any major negative impacts on the surrounding ecosystems (including soil health, biodiversity, water, criteria air pollution) or local communities. 
* Develop and share a strategy for mitigation of adverse impacts to air, water, and land quality, including those impacts related to biomass processing and storage. 
* Transparently report any use of toxic and/or persistent environmental pollutants, including agrochemicals used in the production of purpose-grown feedstock.
