2. What is Cool Counties?A pledge to take action on Climate Change Inventory greenhouse gas emissions from internal operations Implement policies and programs to reduce emissions Coordinate efforts with Minnesota State departments Support state legislation that is consistent with Hennepin Countys goals Urge action at the federal level to reduce emissions 3. Why Join Cool Counties?Minnesota has already codified strict GHG reductions Enhances existing HC policies & programs for energy efficiency Ensures measurement & documentation of HCs emission reductions Provides direction to county departments 4. Minnesota Goals Compared to Cool Counties GHG Emission Reduction GoalsCool CountyMN 100908070 % Goal605040302010 02010 2015 2020 20252030 2035 2040 2045 2050Year 5. Compile an accurate emissions inventory Create emissions baseline and past 3-5 years accomplishments 86 owned facilities, 57 leased facilities, 676 vehicles Establish recordkeeping requirements and protocols; identify responsible parties Recommend reductions from County operations Review & Assess GHG monitoring and reporting protocols Identify federal, state & other grant opportunities 6.
