Landfill methane recovery and destruction

Federal offset protocol
Version 1.0

June 2022

Foreword

Canada’s Greenhouse Gas (GHG) Offset Credit System is established under Part 2 of the Greenhouse Gas Pollution Pricing Act (GGPPA) to encourage cost-effective domestic GHG emission reductions from activities that are not covered by carbon pollution pricing and that go beyond legal requirements.

Canada’s GHG Offset Credit System consists of:

Only project activities following an approved federal offset protocol and meeting all requirements outlined in the Canadian Greenhouse Gas Offset Credit System Regulations can generate offset credits in the Canada’s GHG Offset Credit System.

1.0 Introduction

Methane (CH4) emissions from landfills are generated by the anaerobic decomposition of organic material in the buried waste. The installation of a landfill gas (LFG) recovery and destruction system enables the landfill CH4 to be converted into biogenic carbon dioxide, instead of allowing it to be passively released to the atmosphere.

The Landfill Methane Recovery and Destruction protocol is intended for use by a proponent undertaking a project to actively recover and destroy LFG to generate offset credits under the Canadian Greenhouse Gas Offset Credit System Regulations.

The proponent must follow the methodology and requirements set out in this protocol to quantify and report greenhouse gas (GHG) emission reductions generated by the eligible project activities. This protocol is designed to ensure the project generates GHG emission reductions that are real, additional, quantified, verified, unique and permanent. The protocol is also developed in accordance with the principles of ISO 14064-2:2019 Greenhouse gases – Part 2 – Specification with guidance at the project level for quantification, monitoring and reporting greenhouse gas emission reductions or removal enhancements to ensure reported GHG emission reductions generated as a result of implementing the project activities are relevant, complete, consistent, accurate, transparent, and conservative.

GHG emission reductions generated by a project under this protocol can only result from avoided CH4 emissions achieved through the active recovery of LFG from within the project site and its destruction in  an eligible destruction device, which can include open and enclosed flares, boilers, turbines, internal combustion engines, stations for the direct injection of upgraded LFG into a natural gas network, or stations for the compression or liquefaction of upgraded LFG prior to its transport and injection into a natural gas network. 

Projects that use the recovered LFG to generate energy or heat may reduce their GHG emissions from fuel combustion. While this activity is encouraged, GHG emission reductions from fossil fuel displacement (i.e. fuel switching) are not included in the quantification of GHG emission reductions under this protocol. Proponents may be able to generate credits for this activity under other crediting mechanisms.Footnote 1  However, proponents are responsible for ensuring that any GHG emission reductions credited under the Canada’s GHG Offset Credit System are unique and not credited by another GHG emission reduction mechanism.

3.0 Baseline scenario

3.1 Baseline condition

The following baseline condition must apply in the baseline scenario in order for the project to be eligible under this protocol:Footnote 2

4.0 Project scenario

4.1 Project condition

The following project condition must apply in the project scenario in order for the project to be eligible under this protocol:Footnote 3

4.2 Eligible project activities and equipment

Eligible project activities include the following:

Table 1: Eligible destruction devices
Type Description
Open flare A device with a pilot flame at the top of a vertical stack that is exposed to atmosphere that combusts and destroys a gas.
Enclosed flare A device with an insulated cylinder stack surrounding a burner manifold and combustion/cooling air louvers that combusts and destroys a gas.
Boiler A device that combusts a fuel in order to heat a fluid, such as water or leachate, generating vapour that provides thermal energy for various purposes.
Turbine (micro or large) A device that compresses air to combust with a fuel in order to produce expanding gas that turns turbine blades, generating mechanical energy that can be harnessed by a load (e.g. a generator producing electricity).
Internal combustion engine (stationary or mobile) A device that compresses and combusts an air-fuel mixture in a cylinder in order to produce expanding gas that moves a piston and crankshaft, generating rotary mechanical energy that can be harnessed by a load (e.g. a generator producing electricity).
Station for direct injection of upgraded LFG into a natural gas network a A device that monitors and prepares upgraded LFG for injection into a natural gas network; this can include odourizing the gas, metering the flow, regulating the pressure, and monitoring the chemical composition prior to injection.
Station for compression or liquefaction of upgraded LFG prior to transport and injection into a natural gas network A device that compresses or liquefies upgraded LFG for transport to a station for its injection into a natural gas network (see above).

a Upgraded LFG injected into a natural gas network is considered to be destroyed once it is delivered to a station for direct injection or a station for compression or liquefaction.

5.0 Additionality

5.1 Legal additionality

GHG emission reductions generated by the project must not occur as a result of federal, provincial or territorial regulations, municipal by-laws, or any other legally binding mandates such as operating permits. This includes legal requirements to recover and destroy all or a portion of LFG from the landfill to reduce GHG emissions from the landfill or control of the release of LFG for reasons such as safety precautions (to reduce potential for an explosion) or odour control.

A project at a landfill site with a legal requirement to recover and destroy any portion of its LFG is not considered to be additional, and therefore is not eligible for registration.

If at any time after project registration the GHG emission reductions generated by the project are required by law or the result of a legal requirement, the GHG emission reductions can only be quantified and offset credits can only be issued up to the date immediately preceding the date on which the law or the legal requirement comes into force.

5.2 Provincial or Federal pricing mechanisms for GHG emissions

Any emission sources that are included in an industrial facility’s GHG emissions reported under a federal, provincial or territorial pricing mechanism for GHG emissions are not eligible for offset credits. This includes on-site landfills at covered facilities under the federal Output-Based Pricing System.

6.0 General requirements

6.1 Project start date

The start date of a project corresponds to the first day that LFG actively recovered from within the project site is destroyed in an eligible destruction device. In the case of the injection of upgraded LFG into a natural gas network, the LFG is considered to be destroyed once it is delivered to a station for direct injection or a station for compression or liquefaction.

6.2 Crediting period

A project implemented under this protocol has a crediting period as specified in the Regulations.

6.3 Crediting period renewal

A project implemented under this protocol is eligible for crediting period renewal as specified in the Regulations.

6.4 Aggregation

There are no additional provisions regarding aggregation for this project type, beyond what is specified in the Regulations.

6.5 Project location and geographic boundaries

The proponent must document and report the location and geographic boundaries of the project site and submit a site plan. The site plan must show where the project site is situated with respect to the landfill site, relevant landfill cell(s) and any end user facilities. The site plan must also show the location and arrangement of all the project components associated with LFG recovery and destruction, including the active recovery system within the project site; treatment, purification and upgrading equipment; eligible destruction devices; measuring devices; and any other equipment associated with the GHG sources, sinks and reservoirs (SSRs) within the project GHG boundary (Section 7.0).

The geographic boundary of the project site cannot change after the first reporting period, but project activities can expand within the boundary. Any changes to the site plan must be communicated as specified in the Regulations.

6.6 Environmental and other safeguards

The proponent must ensure that the project activities comply with any operating permits, municipal by-laws or regulations applicable to the landfill site, including those related to minimizing noise and odour, and ensuring the safe operation of all systems within the project site.

7.0 Project GHG boundary

The project GHG boundary (Figure 1) contains the eligible project activities and the GHG SSRs that must be assessed by the proponent in order to determine the GHG emission reductions generated by the project activities relative to the baseline scenario.

Table 2 provides additional details on the SSRs identified for the baseline and project scenarios, as well as justification for their inclusion or exclusion in the quantification of GHG emission reductions. The proponent must quantify and report on each of the “included” SSRs that are relevant to the specific activities taking place in the baseline and project scenarios.

Three GHGs are relevant to the SSRs in this protocol: Carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). CO2 emissions from the decomposition of organic material and destruction of landfill CH4 are considered biogenic and are excluded from the quantification of GHG emissions in this protocol.

Figure 1: Illustration of the project GHG boundary

Long description

Figure 1 depicts an illustration of the project GHG boundary. This includes a flow chart depicting the relationship between the SSRs that are relevant to the project, and a dotted line delineating those within the project GHG boundary.

SSR 1, SSR 2 and SSR 3 are related to the baseline and project scenarios, but are upstream from the project GHG boundary and, therefore, outside of the dotted line.

SSR 4 is within the project GHG boundary for the both baseline and project scenarios.

SSR 5 to SSR 12 are within the project GHG boundary for the project scenario only.

SSR 1 leads into SSR 2 which leads into SSR 3 which leads into SSR 4 which leads into SSR 5. SSR 5 then leads into SSR 7 to 12 individually. SSR 6 leads exclusively into SSR 7.

8.0 Quantification methodology

This section contains the quantification methodology that must be followed to calculate baseline and project scenario GHG emissions, which are subsequently used to calculate the GHG emission reductions generated by the project.

Raw data must be converted to align with the units presented in the quantification methodology, if necessary (see Section 8.5 for a tabulated summary). Schedule A provides the reference condition values that must be applied to complete the quantification. Emission factors that must be used are provided in the Emission Factors and Reference Values document and may also need to be converted to align with the units presented in the quantification methodology. The proponent must ensure they are using the most current version of the Emission Factors and Reference Values document.

Baseline scenario GHG emissions are the GHG emissions that would have occurred in the absence of the project, quantified based on SSRs within the project GHG boundary. Project scenario GHG emissions are the actual GHG emissions that occur from SSRs within the project GHG boundary.

The GHG emission reductions generated by the project are quantified by deducting the project scenario GHG emissions from the baseline scenario GHG emissions as outlined in Section 8.4.

Both baseline and project scenario GHG emission calculations must include all the GHG emissions that occurred during the reporting period, and must include sub-totals in tonnes of CO2 equivalent (t CO2e) for each full or partial calendar year to support serialization of the resulting offset credits by calendar year.

8.1 Baseline scenario quantification

The proponent must follow the below quantification methodology to quantify the baseline scenario GHG emissions for each full or partial calendar year covered by the reporting period, based on the included SSRs outlined in Table 2.

This protocol quantifies the baseline scenario GHG emissions through the use of a dynamic baseline approach based on measurements made in the project scenario instead of modelling the GHG emissions generated by the landfill in the baseline scenario. This means that the baseline scenario GHG emissions are calculated based on the quantity of landfill CH4 that is actively recovered in the project scenario, which may vary over time.

Equation 1: Baseline scenario GHG emissions

Long description

Equation 1: Baseline scenario GHG emissions

BE = CH4RECPR  x (1-OX)

The baseline scenario GHG emissions during a calendar year covered by the reporting period are equal to the quantity of landfill methane recovered by the active LFG recovery system during a calendar year covered by the reporting period, multiplied by, open parenthesis, one minus the factor for the oxidation of landfill methane by bacteria in soil or materials covering the waste, close parenthesis.

The baseline scenario GHG emissions during a calendar year covered by the reporting period are represented by the symbol BE and are expressed in tonnes of carbon dioxide equivalent.

The quantity of landfill methane recovered by the active LFG recovery system during a calendar year covered by the reporting period corresponds to SSR B4, is represented by the symbol CH4REC sub PR, is expressed in tonnes of carbon dioxide equivalent and is quantified as per Equation 2.

The factor for the oxidation of landfill methane by bacteria in soil or materials covering the waste is represented by the symbol OX and is unitless.

Baseline scenario GHG emissions are quantified based on the presumption that the landfill CH4 actively recovered in the project scenario would have been passively released to the atmosphere in the baseline scenario. Oxidation of landfill CH4 emissions must be accounted for in the baseline scenario. If a non-geomembrane cover system or other CH4 oxidation technology is present, it can be presumed that the landfill CH4 would have been subject to oxidation by bacteria in the soil or materials covering the waste prior to being released to the atmosphere. If a geomembrane covers the entire landfill area and no other CH4 oxidation technology is present, it can be presumed that the landfill CH4 would not have been subject to oxidation.

Oxidation of landfill CH4 emissions must be accounted for in the following manner:

Equation 2 and Equation 3 must be used to calculate the quantity of landfill CH4 recovered by the active LFG recovery system for each full or partial calendar year covered by the reporting period.

If the flow meter does not automatically correct the measured volume to the reference temperature and pressure conditions, the proponent must calculate the corrected volume following Equation 4. Equation 4 is not needed if the flow meter automatically corrects the volume.

Equation 4: Volume of LFG delivered to an eligible destruction device, corrected to reference condition

Long description

LFGi,t= LFGUC x Tref/Tm x Pm/Pref

The corrected volume of LFG delivered to eligible destruction device, i, during measurement period, t, is equal to the uncorrected volume of LFG delivered to eligible destruction device, i, during measurement period, t, multiplied by the fraction of the reference temperature of the LFG, over the measured temperature of the LFG for the measurement period, t, multiplied by the fraction of the measured pressure of the LFG for the measurement period, t, over the reference pressure of the LFG.

9.0 Reversals

This section does not apply to this project type.

9.1 Reversal risk management plan

This section does not apply to this project type.

9.2 Permanence monitoring

This section does not apply to this project type.

10.0 Environmental integrity account

There are no additional provisions regarding the deposit of offset credits generated into the environmental integrity account, beyond what is specified in the Regulations.

11.0 Measurement and data

11.1 Data and information management

There are no additional provisions regarding data and information management, beyond what is specified in the Regulations.

11.2 Measuring devices

The proponent must ensure the appropriate measuring devices are installed and operated to achieve the frequency of data measurement outlined in Section 8.5.

11.2.1 Flow meters

The LFG recovery and destruction system must include permanent flow meters that directly and separately measure the volume of LFG actively recovered from within the project site and delivered to the individual eligible destruction device(s). The volume of any fossil fuels used for the operation of the active LFG recovery system, treatment equipment, or eligible destruction devices must be measured by permanent flow meters or determined using purchasing records. Volume data must be converted into cubic metres (m3) to align with the quantification methodology presented in Section 8.0.

11.2.2 Temperature and pressure gauges

If a flow meter automatically corrects the LFG volume to the reference temperature and pressure conditions set out in Schedule A – Reference condition values, no additional temperature and pressure gauges are required.

If a flow meter does not automatically correct the LFG volume, permanent temperature and pressure gauges must be installed to measure temperature and pressure at the same measurement frequency as the LFG volume (See Section 8.5). LFG temperature and pressure must be measured under the same conditions (wet or dry basis) as the LFG volume

The LFG volume data must be corrected from measured temperature and pressure conditions to the reference temperature and pressure conditions set out in Schedule A – Reference condition values by using Equation 4.

11.2.3 Methane analyzers

The active LFG recovery system must include permanent methane analyzers (e.g. gas chromatographs) that directly measure the CH4 content in the LFG on a volumetric basis. LFG CH4 content should be measured under the same conditions (wet or dry basis) as LFG volume, temperature and pressure.

11.2.4 Arrangement of measuring devices

Flow meters and methane analyzers must be arranged in such a way as to ensure the data is representative of the LFG actively recovered and destroyed by the project.

Additionally, flow meters and methane analyzers must be placed to:

A moisture-removing component may separate a methane analyzer and a flow meter where the methane analyzer is placed upstream of the moisture-removing component (CH4 content measured on a wet basis), and the flow meter is placed downstream of the moisture-removing component (LFG volume measured on a dry basis). A moisture-removing component must not separate a methane analyzer and flow meter in any other configuration other than previously described. No other devices or equipment that could change the LFG composition by volume may separate a methane analyzer and a flow meter.

11.3 Quality assurance and quality control

Quality assurance and quality control procedures must be implemented to ensure that all measurements and calculations have been made correctly and can be verified.

All flow meters and methane analyzers must be:

The measurement accuracy of all measuring devices must show that the measuring device provides a reading that is within a ± 5% accuracy range. When the accuracy of the measuring device deviates from the ± 5% range, the appropriate corrective action(s) must be taken, in accordance with the manufacturer specifications.

After the corrective action(s), the measuring device must be rechecked for accuracy. If the accuracy of the measuring device is still not within the ± 5% range, the measuring device must be calibrated by the manufacturer or by a third party certified for that purpose and following manufacturer specifications, no more than two months after the end of the reporting period.

For the entire period from the last time the measuring device showed a reading within ± 5% accuracy until the measuring device shows a return to ± 5% accuracy:

11.4 Missing data

If a measuring device fails to produce data as required in Section 8.5, missing data may be substituted using the methodology in this section. If missing data is not substituted using the methodology below, no GHG emission reductions can be quantified for the period during which data is missing.

Missing data from a measuring device may only be substituted if the following two conditions are met during the period of missing data:

  1. The operational status of the eligible destruction device(s) can be demonstrated in accordance with the requirements in Section 11.5.
  2. The proper functioning of the thermocouple or destruction device monitoring instrument(s) referred to in Section 11.5 can be demonstrated with the appropriate data.

Missing data from a flow meter or methane analyzer may only be substituted in accordance with the following rules:

For a project with LFG volume or CH4 content data missing for a period of up to seven consecutive days, the appropriate substitution method from Table 5 may be employed to substitute the data.

In the event that periods of missing data occur more than once during the reporting period, data may be substituted for:

Table 5: Missing data substitution methods
Missing data period Substitution method
Less than 6 consecutive hours Use the average of the 4 hours immediately prior to and after the missing data period.
6 to less than 24 consecutive hours Use the 95% upper or lower confidence limit of the 72 hours prior to or after the missing data period, whichever results in greater conservativeness.
1 to 7 consecutive days Use the 90% upper or lower confidence limit of the 72 hours prior to or after the missing data period, whichever results in greater conservativeness.
More than 7 consecutive days No data may be substituted after the 7th consecutive day, and no GHG emission reductions may be quantified.

11.5 Operational status of eligible destruction devices

The operational status of the eligible destruction device(s) must be monitored with a destruction device monitoring instrument and recorded at least hourly to ensure LFG destruction is occurring.

For a flare (open or enclosed), the operational status must be determined based on data from a thermocouple. The thermocouple must indicate that the flare temperature meets or exceeds 260˚C, the minimum combustion temperature for CH4. If the temperature is below 260˚C, no GHG emission reductions can be quantified for the period during which the temperature remains below 260˚C.

For boilers, turbines, internal combustion engines, stations for the direct injection of upgraded LFG into a natural gas network, or stations for the compression or liquefaction of upgraded LFG prior to its transport and injection into a natural gas network, a destruction device monitoring instrument must monitor and measure an indicator of operational status (e.g. energy output). If the operational status is not monitored and an indicator is not measured, no GHG emission reductions can be quantified for the period during which monitoring data is not measured.

When LFG is transported to an end user facility, monitoring data demonstrating the operational status of the eligible destruction device(s) must be made available to the proponent or the GHG emission reductions can not be included in the quantification.

If an eligible destruction device, thermocouple or other destruction device monitoring instrument is not operating or functioning properly in accordance with the manufacturer specifications, no GHG emission reductions can be quantified for the period during which they are not operating or functioning properly.

12.0 Records

In addition to the record keeping requirements in the Regulations, the proponent must retain records that support the implementation of a project, including invoices, contracts, metered results, maintenance records, calculations, databases, photographs, and calibration records, at the location and for the period of time specified in the Regulations. These records apply to any eligible destruction devices, measuring devices or meters located at the landfill site or end user facility, if applicable. For a Landfill Methane Recovery and Destruction project, additional records include:

13.0 Verification requirements

13.1 Competency requirements for verification teams

There are no additional provisions regarding competency requirements for verification teams for this project type, beyond what is specified in the Regulations

14.0 Reporting requirements

In addition to the reporting requirements specified in the Regulations, the proponent must report the quantified GHG emissions for each SSR included in the baseline and project scenarios in t CO2e for each full or partial calendar year covered by the reporting period.
