1 Greenhouse Gas Offsets in Livestock Systems

2 Overview

3 Context in Alberta, Canada Canada 1990 National Inventory Report on Greenhouse Gas (GHG) Sources and Sinks Science basis, draft agricultural protocols Alberta emitting 37% national totals Alberta 2002 Taking Action on Climate Change Strategy Learn by doing, continuous improvement 2005 Emission reporting 2007 Specified Gas Emitters Regulation > 100,000 T CO2e / yr, intensity reductions 12% /yr, four compliance options 2012 Increased verification requirements 2014 Increased target, carbon price 2015 Climate Leadership Plan Hard cap on emissions, off coal by 2030, carbon tax on fuel use, energy efficiency program 2010 GHG Emissions Data from National Inventory Report, Environment Canada, 2012 Forecast Environment Canada outlook to 2020

4 Carbon Offsets Regulated emitters can: 1) Reduce emissions 2) Trade performance credits 3) Pay $15 / T CO2e 4) Purchase voluntary offsets Unregulated emitters can: Voluntarily lower emissions Reduce, remove or replace fossil fuels Sell emission abatements

5 Offset Quantification Protocols International Standard (ISO ) Compatible between different sources and types of emissions Best, most recent science Identify emission factors, calculations Compare net emissions from all GHG in Baseline vs Project conditions Records to verify practice change Costs reduced by prescribed process Assured by: Government approval of protocols Third party verification Alberta Emissions Offset Registry Provides certainty for emitters, investors and government about amounts of CO2e abated

6 Offset Framework Science Additional / Real - Management improvements beyond business as usual Policy Quantifiable - Sound science - Measured, extrapolated - Accepted, peer reviewed Offset Verifiable - Records, data management - 3 rd parties, accountants, engineers Practice

7 Agricultural Protocols Energy Biogas * Biofuel , version Energy Efficiency Biomass , now Waste Biomass Renewable Micro-Energy Generation Cropping Tillage *, now Conservation Cropping * Nitrous Oxide Emissions Reduction (NERP) 2007, version ** Livestock Dairy Protocol ** Beef Reduced Days on Feed Beef Reduced Age at Harvest Beef Low Residual Feed Intake * Protocols in use by primary producers at $15 / T CO2e ** Protocols developed by private industry

8 Uptake of Offsets Source: Alberta Emissions Offset Registry, January 2016 Over 12 Mt CO2e - primarily Tillage, some Biogas (manure) Represents close to 1/3 of offsets used for compliance Over $160 M in offset sales (assuming $12 / T CO2e) After 2012, rate of offsets declined from 1.0 Mt CO2e / yr for Tillage Management to 0.1 Mt CO2e / yr for Conservation Cropping

9 Dairy Protocol Improved feed quality, manure management, feed quality and/or reduced replacement herd On-farm pilot study*, 100 farms Producers and third parties (e.g. Alberta Milk) supplied records Results of mock verification : o Most not collecting all records needed o Clarification needed about data and types of documentation o Improvements require collaboration o Value of offsets not motivating Revised protocol to clarify records, streamline calculations 2014 *Funding by Agriculture and Agri-Food Canada

10 Beef Protocols Reduced Days on Feed Feedlot finishing phase - Diet changes, feed additives (e.g. edible oils) - Revised to Reducing GHG in Fed Cattle 2014 Reduced Age to Harvest Entire lifespan - Move harvest closer to optimum market weight Low Residual Feed Intake Genetic selection for lower maintenance and increased feed utilization at same level of production

11 Agricultural Offsets Challenges Science Emissions variable, unconcentrated Complex, 3 types of GHG Segmented Measurement Time, expertise Policy Price Changes Expectations increasing Regulated Practice Records Data management systems 3 rd party verification Transaction costs Opportunities Large numbers, areas Model development Increased efficiencies Integrated systems Rationale for funding Co-benefits, efficiencies Demand increasing Capacity is transferrable New types of evidence Simplify, scale Transferable
