What’s “carbon intensity” again? • A measure of the total CO2-equivalent emissions produced throughout a fuel’s lifecycle • Measured in grams of CO2-equivalent GHG emissions per unit of energy in fuel gCO2e/MJ
Carbon Intensity Calculation: Conventional Gasoline Well-To-Tank Carbon Intensity: 16.9 gCO2e/MJ + Carbon Content of Fuel: 72.9 gCO2e/MJ + Vehicle emissions of CH4 and N20: 2.47gCO2e/MJ = Lifecycle Carbon Intensity: 92.3 gCO2e/MJ
Emissions from Indirect Land Use Change • Plants and soils store large amounts of carbon that is released during land conversion • Diversion of corn or other crops from existing markets to biofuels production can induce farmers elsewhere to bring new acreage into production • Initial carbon release from land conversion event may exceed GHG benefits of displacing use of petroleum or other fossil fuels
.06 forest .24 grassland converted to agriculture ~30 metric tons CO2 released -29 CO2 Net GHG Emissions Produces ~400 gallons/yr ethanol Saves ~1 metric ton CO2 emissions annually Example of Indirect Land Use Change Emissions One acre cropland devoted to corn ethanol Source: CARB 2009, based on GTAP modeling.
Local/Regional Biomass Feedstocks • Municipal Solid Waste • Only items that have reached the end of their use cycle (non-reusable, non-recyclable) • The Northeast’s most significant resource • Less likely to induce additional LUC than virgin feedstocks • Woody Biomass • New England has substantial woody biomass but also many existing markets (e.g., pulp and paper, exports) • NY and PA combine for approximately two-thirds of total supply • Agricultural Residues • New York and Pennsylvania dominate again, approximately 75 to 90 percent of agricultural biomass resources

Transportation Sector GHGs are Important! • GHG emissions from transportation are large and increasing (over 30% of total in most states) • Transportation GHG emissions affected by: • Amount and type of transportation fuels • Efficiency of motor vehicles • Number of vehicle miles traveled
Connecticut Delaware Maine Maryland Massachusetts New Hampshire New Jersey New York Pennsylvania Rhode Island Vermont Northeast/Mid-Atlantic Low Carbon Fuel Standard • December 2008: Commissioners from 11 Northeast and Mid-Atlantic states signed Letter of Intent to develop framework for regional LCFS • Governors will sign LCFS Memorandum of Understanding this month
“What is a Low Carbon Fuel Standard?” • Performance-based standard for fuels • Does not “pick winners” or ban any fuel • Regulates “carbon intensity” or lifecycle carbon emissions from fuels • Requires displacement of conventional transportation fuels with advanced fuels that have low carbon intensities, such as: • Natural gas • Low-carbon biofuels • Electricity generated with renewable sources • Hydrogen produced from renewable sources
“What is a Low Carbon Fuel Standard?” • Would require reductions in carbon intensity from today’s transportation fuels: • Gasoline • Diesel • Requires lifecycle GHG accounting for • All baseline fuels • Low-carbon substitutes on an opt-in basis • Heating oil could be included • NOT A CAP ON TRANSPORTATION EMISSIONS
How is the LCFS Different From Other Regulations? • Typical vehicle and fuel standards regulate tailpipe emissions • LCFS regulates GHG emissions from the full fuel lifecycle • Cap-and-trade regulations limit total emissions allowed • LCFS regulates only the “intensity” of emissions for a unit of fuel • Total transportation emissions could still increase if total energy use increases • LCFS complements vehicle efficiency standards and travel demand management strategies
Program Structure: Who is Regulated? • Providers of most petroleum and biofuels are ‘regulated parties’ • Providers of fuels that meet 2020 levels must ‘opt in’ to earn credits: • Electricity • Hydrogen • Natural Gas
Flexible, Market-Driven Compliance Options • Supply a mix of fuels with carbon intensity equal to the standard • Provide fuels that have lower carbon intensity than the standard • Use purchased or banked credits to meet the standard
Regional LCFS Initiative: Stringency • California’s LCFS requires a 10% reduction in GHG-intensity of fuels by 2020 • States are not required by any law to adopt the same LCFS stringency as California • Given the interconnected nature of the region’s fuel supply network, adopting the same stringency within the region is optimal • Facilitate compliance for regulated parties • Maximize program effectiveness
What is Lifecycle Analysis? • An accounting of the emissions associated with each stage in the life of a product. • Production • Transport • Storage • Delivery • End Use • “Cradle-to-Grave”, “Well-to-Wheels”, “Full Fuel Cycle”… • Simple addition… …but keeping track of every stage can be very complicated!
