American Carbon Registry
  • First and largest U.S. private voluntary GHG registry
    • Founded 1997 by Environmental Defense Fund and Environmental Resources Trust
    • Over 30 million tons issued to date
    • 2008: most widely used voluntary registry in the world (State of the Voluntary Carbon Market 2009)
  • Established industry standard for transparent on-line reporting and serialization of verified project-based offsets
  • Joined Winrock International in 2007
  • Project types:
    • Forestry (AR, IFM, REDD), livestock manure, landfill gas, wastewater treatment, Carbon Capture & Storage, industrial gas substitution, fugitive methane in oil & gas sector, truck stop idling
winrock carbon expertise
Winrock carbon expertise
  • Internationally recognized team of AFOLU carbon experts
    • Nobel prize winners for IPCC contributions
    • Member of CDM EB Afforestation/Reforestation Working Group
    • Former Board member now Executive Secretary of UNFCCC
  • Terrestrial carbon analyses, methodologies, protocols, methods manuals for –
    • USDA, U.S. Forest Service, USDOE 1605(b)
    • Two DOE Regional Carbon Sequestration Partnerships
    • USAID, World Bank, International Tropical Timber Organization
    • EPRI and electric utilities
    • Methodologies for CCAR, VCS, ACR, CCBA, RGGI
  • For USEPA:
    • Scoping and ranking AFOLU GHG mitigation activities
    • Developing new Climate Leaders methodologies
protocol development process
Protocol Development Process
  • ACR publishes general and sector-specific standards
  • Flexibility in methodology choice
    • Use ACR-published methodology
    • Use approved CDM methodology
    • Propose/modify existing methodology
    • Submit new methodology for approval
  • Public consultation and anonymous scientific peer review of all standards and methodologies
    • Shortest time to market and lowest cost
    • Emphasis on scientific rigor
    • Balance environmental integrity with commercial flexibility
n 2 o from fertilizer in the u s
N2O from Fertilizer in the U.S.
  • Analysis of 129m acres wheat, corn and cotton in 31 states
    • 6.2m tonnes of nitrogen applied
    • 3 fertilizer types
  • Modified Bouwman model:
    • Fertilizer quantity, type, soil texture and drainage, pH soil carbon concentration used to predict N2O emissions
  • 61m tonnes CO2e emissions
    • 70% corn, 25% wheat, 5% cotton
  • 0.12 - 1.45 tCO2e ac-1yr-1
county level emissions from anhydrous ammonia tco 2 e acre yr
County-level emissions from anhydrous ammonia (tCO2e/acre-yr)

n 2 o methodology development
N2O Methodology Development
  • Phase I: simplified Bouwman methodology
    • Fertilizer type, soil carbon concentration, drainage, pH, soil texture, crop type
    • Test sites in AR (cotton), IA (corn), CA (lettuce)
    • Improvement on IPCC Tier 1; insufficient for seasonal variations
  • Phase II: highly parameterized, calibrated model
    • Examine changes in fertilizer type, quantity, timing, placement
    • No decrease in yield
    • Accounts for site-specific and temporal factors
    • Direct N2O emissions from fertilizer, and indirect emissions from nitrate leaching and ammonia volatilization, estimated for baseline and project scenario
    • Data-intensive but rigorous results; cost-effective for aggregated projects
future work in ag space
Future Work in Ag Space
  • Improved Grazing Land Management
    • Soil carbon enhancement, enteric methane, manure management
  • Agricultural soil carbon enhancement
  • Reducing N2O emissions from poultry operations in Arkansas
  • Reducing CH4 emissions from rice operations in Arkansas
  • Possible rangeland and agricultural methodologies in Australia
  • China: enhancing grassland productivity and reducing livestock methane emissions
