Since 2008, we have measured our Company’s greenhouse gas (GHG) emissions and energy use, and have set goals to reduce these environmental impact areas. In 2012, we set a companywide goal to reduce our energy use and GHG emissions by 19% by 2017, and we have made progress towards this goal. In 2015 our CO2e emissions declined 7% and our energy use declined 19% per half gallon equivalent of milk compared with our 2012 baseline.
Since we first began tracking our emissions and energy use, our goals boundary has expanded, as we have added additional lifecycle stages into our company footprint. The energy use and emissions stages we now include in our goals boundary are: the farms and pasture we manage, our dairy cows, raw milk transport and our plant and cold storage facility. To view our full Life Cycle Assessment of AOD milk, please refer to our 2015 Corporate Citizenship Report.
We have many initiatives in place to reduce our utility-based emissions and energy use at our farms and processing plant. Our plant expansion and construction of our onsite cold storage facility incorporate energy-efficient systems and technologies. Our farms have programs in place to reduce idling time of farm vehicles and to replace farm building lights with LEDs, and we have reduced the average shipping distance of our raw milk. However, cow-related emissions make up approximately 74% of our companywide GHG emissions. We use best management practices, such as composting our manure, to reduce the manure-related emissions, and continue to research options to reduce enteric emissions in an organic system.
