How to do an inventory? 5 1 Metric Ton = 1,000 kilograms (2,205 lbs.) Equivalent to GHG emissions from any of the following: 112 gallons of gasoline One passenger vehicle driven 2,288 miles Roughly 5% of the energy use in one US household per year What’s a metric ton, really? 6 Source: Creative Commons Licensed, Carbon Visuals, Ltd. (2015) 7 Total GHG emissions from MWMC activity in FY 2017-18 was the highest since inventories began in 2010 Capital construction (CIP projects) was the predominant increase to overall emissions* Emissions from day-to-day operations* decreased in comparison to emissions in the FY 2015-16 inventory period MWMC activity offset GHG emissions owing to tree-farm CO2 sequestration and CoGen electricity and natural gas displacement * Operations is the largest proportion of overall GHG emissions The FY 2017-18 findings: 8 Total FY 2017-18 GHG Emissions from MWMC Activity 9 Offset GHG Emissions from MWMC Activity 10 Inventory Methodology General Reporting Protocol (GRP) categories of GHG emissions: Scope 1 – “direct emissions” from operating equipment and facilities Scope 2 – emissions from purchased electricity (what was consumed) Scope 3 – “indirect emissions” from supply-chain and service providers 11 Total GHG Emissions by Scope 12 Scope 1 – Direct Emissions, O&M Activity 13 Scope 2 – Purchased/Consumed Electricity 14 Scope 3 – Indirect Emissions, Contracted & Outsourced 15 Numbers for FY 2017-18 The GHG Emissions Results: Scope 1 direct emissions = 4,448 MT CO2e Down 2% from FY 2015-16 Scope 2 emissions (electricity) = 6,789 MT CO2e Down 4% from prior period Scope 3 indirect emissions (3PL, G&S) = 10,149 MT CO2e Up 101% from prior period _________________________________________________________ Total GHG Emissions from MWMC Activity = 21,386 MT CO2e Up 28% from prior period 16 Numbers for FY 2017-18 The GHG Emissions Offset Results: Biocycle Farm CO2 Sequestration = -18,000 MT CO2e All trees on the farm as of June 2018 Soil CO2 Sequestration = -613 MT CO2e Displaced Conventional Fertilizer = -113 MT CO2e Displaced Grid Electricity = -740 MT CO2e Displaced Natural Gas = -1,659 MT CO2e _____________________________________________________ Total GHG Emissions Offset (Approx.) = -21,125 MT CO2e 17 Key Takeaways: Total GHG emissions from MWMC activity at 21,386 MT CO2e Daily O&M is roughly half of total GHG emissions * Not including Operations Supply Chain from Scope 3 Total Scope 3 indirect emissions at 10,149 MT CO2e CIP Projects accounted for 5,575 MT CO2e Total GHG emissions offset (benefit) at about -21,125 MT CO2e FY 2017-18 GHG Inventory 18 FY 2017-18 GHG Emissions Report Any questions? Commission discussion 19 20 FY 2017-18 GHG Emissions Report Supporting Detail Slides 21 Good Company (est. 2001) is a leading provider of professional consultation and services for sustainability planning in the public and private sectors Provides a data gathering methodology and “calculator” (Microsoft Excel workbook) for the water/wastewater industry Applies the MT CO2e conversion formulas collaboratively produced by the Local Government Operations Protocol (LGOP), The Climate Registry (TCR), California Air Resources Board (CARB), Climate Action Reserve (CAR), Urban Forest Protocol (UFP), ICLEI Local Governments for Sustainability, and Biosolids Emissions Assessment Model (BEAM) Referred to simply as the General Reporting Protocol (GRP) Clients include City of Eugene, EWEB, Lane County Waste Management, Kennedy/Jenks Consultants, PGE, ODT, ODE, and many others What “calculation tool”? 22 Scope 1 – “Direct Emissions” from MWMC Operations 23 Scope 2 – Electricity Consumption, Market v. Location Based 24 Numbers for FY 2017-18 The GHG Emissions Results: Scope 1 direct emissions (operations) = 4,448 MT CO2e Down 2% from FY 2015-16 at 4,533 Scope 2 emissions (electricity) = 6,789 MT CO2e Down 4% from FY 2015-16 at 7,095 Scope 3 indirect emissions (goods and services) = 10,149 MT CO2e Up 101% from FY 2015-16 at 5,053 Among all Scope 3 sub-categories, capital supply chain up 1,304% ______________________________________________________________________________ Total GHG Emissions from MWMC Activity = 21,386 MT CO2e Up 28% from FY 2015-16 at 16,681 25 Numbers for FY 2017-18 26 Numbers for FY 2017-18 27
