Regulations Summary

ASTM D6866 is an analytical method that measures the biogenic fraction of fuels (solid and liquid) as well as their combustion emissions.

These are regulations that recommend or require these carbon dating-based methods.

Protocols and Organizations Requiring ASTM D6866

  • California AB32 Mandatory GHG Emissions Reporting (Read More)

ASTM D6866 is used to measure the percentage of carbon-neutral CO2 emissions from the combustion of biomass, municipal solid waste, or waste-derived fuels with biomass.

AB32 allows fuel sampling in lieu of emissions sampling as long as (a) the fuel is supported by ASTM D6866, and (b) the samples collected for analysis is representative of the entire composition of the fuel.

AB32 was superseded by Senate Bill 32 (SB32).

  • Western Climate Initiative (WCI) Requirements of Mandatory Reporting (Read More)

Owners/operators of general stationary combustion units using mixed fuels and waste-derived fuels are mandated to use ASTM D6866 to determine the biomass-derived fraction of their carbon dioxide emissions.

  • US EPA Final Mandatory GHG Reporting Rule (Read More)

ASTM D6866 is used to determine the biogenic CO2 of emissions from the combustion of municipal solid waste and mixed fuels (biogenic and non-biogenic fuels).

  • UN CDM Methodology ACM0022:“Large-scale Consolidated Methodology – Alternative waste treatment processes” (Read More)

ASTM D6866 testing is done to measure the fraction of fossil carbon in the total carbon content of municipal solid waste.

  • The Climate Registry Protocols

When calculating emissions from waste fuels and biomass, ASTM D6866 testing is required.

Local governments are required to identify and report biomass CO2 emissions as biogenic emissions, separate from fossil fuel emissions. ASTM D6866 is recommended when measuring biogenic emissions from biofuels, waste fuels, and biomass co-firing in a unit with CEMS.

ASTM D6866 is the method identified for partitioning of anthropogenic and biogenic CO2 emissions in the TCR Electric Power Sector Protocol for the Voluntary Reporting Program.

  • Australia Department of the Environment and Energy National Greenhouse and Energy Reporting Scheme

ASTM D6866 analysis is recommended to determine the amounts of each kind of fuel in blended liquid or solid fuels.

  • New Zealand Climate Change Regulations

Under the continuous emissions monitoring method for calculating emissions from combusting used oil, waste oil, used tyres, or waste, total annual emissions of non-biomass CO2, CH4, and N2O from the stacks are measured. ASTM D6866 is used to determine the non-biomass fraction of CO2 emissions if the fuel combusted contains biomass and non-biomass.

Programs Recommending Carbon-14 Method

  • UK Office of Gas and Electricity Markets (OFGEM)

Electricity and gas market regulator OFGEM has approved the use of a carbon-14 method by waste-to-energy installations that want to claim Renewable Obligation Certificates (ROCs). The carbon-14 method is used to determine the biomass energy content of waste feedstock by post-combustion analysis of flue gases.

NOTE: In 2016, OFGEM decided to refuse applications to the Renewables Obligation program proposing the use of the carbon-14 method for waste wood-derived fuels only. Other alternative fuel sources are assessed on a case-by-case basis.

  • Roundtable on Sustainable Biomaterials (RSB) 

RSB offers peer-reviewed, global certification standard for sustainable biomaterials, biofuels and biomass production.

The RSB Standard for Bio-based and Advanced Products (RSB-STD-02-001) describes sustainability requirements for operators involved in the supply chains of bio-based and advanced products. Under the standard, certified bio-based products and bio-based intermediates must have a bio-based carbon content of at least 25% as measured by standardized methods EN 16640, ASTM D6866, CEN/TS 16137:2011 or ISO 16620-1:2015. The standard will be effective by December 10, 2018.

  • Cement Sustainability Initiative’s Cement CO2 and Energy Protocol

The World Business Council for Sustainable Development’s Cement Sustainability Initiative (WBCSD CSI) cites EN 15440 as a standard that can be used to determine the biogenic carbon in an alternative fuel’s overall carbon content. The document is aimed at engineers and managers of cement producers.
