23 Individual facilities are responsible for the purchase and storage of chemicals used in their operations. As part of our chemical management system, chemical types and quantities used at every site are logged in a local chemical inventory, which is updated each month. This year, we created a company-wide chemical inventory (based on purchases) to better understand our global chemical footprint. We plan to include total fertilizer use in future inventories. 2015 Chemical Use Chemical Category Amount Used (Liters) Algaecides 10 Fungicides 20,778 Growth Regulators 761 Herbicides 90,200 Insecticides 24,597 This inventory enables us to better manage our chemical footprint. In 2016, we plan to use our landscape Environmental Impact Quotient (EIQ) to evaluate the impacts of each chemical on the environment. Armed with this knowledge, we will work to reduce or eliminate the most impactful chemicals from our inventory and to lower our overall chemical load. Additionally, in 2015, we collected data on the amount of water needed to mix each of the chemicals in our inventory. Moving forward, we would like to replace or remove water-intensive chemicals from our inventory where possible. Read more about our water management in the Water section of this report. Our clients are also concerned with chemical stewardship and the proper use of chemicals. We regularly engage with them on topics, such as safe and responsible use of chemicals, preventive plant health care and chemical application techniques and alternatives to traditional pesticides and other chemicals. Protecting Pollinators Pollinators, such as honeybees and butterflies, contribute over $24 billion to the U.S. economy, facilitating the growth of fruits, nuts and vegetables. Habitat destruction and food source depletion have led to the loss of these important insects. For instance, over the last 70 years, honeybee colony counts have fallen by 90 percent. Through our scientific research, experience in plant health care and innovative technologies, we can design pollinator habitats that create a suitable environment for pollinators at every stage of their life cycle. Native wildflower species are planted using a customized seed mix tailored for the site conditions. Coordinating these habitats with regular monitoring and proper plant health care may go a long way toward saving our pollinators.
