International Methane and Nitrous Oxide Emissions and Mitigation Data
Below is the methane data set of non-CO2 GHGs for the report: International
analysis of Methane and Nitrous Oxide Abatement Opportunities: Report
to Energy Modeling Forum, Working Group 21 (PDF, 9 pp., 76 KB, About
PDF). The data includes reference methane emissions for five major sources
for 1990, 1995, 2000, 2010, and 2020 as well marginal abatement curves
(MACs) for each sector by the defined regions for the study. All values
are reported as 2000 US Dollars.
Appendix A: Reference Methane Baselines:
The following Excel files contain the baselines for methane by sector for each region from 1990-2020.

Appendix B: Technology Characteristics:
The following tables outline the technical and economic characteristics of each technology (or each point) on the methane and nitrous oxide MAC curve. The technical characteristics include the type of energy recovered (if applicable) and the reduction efficiency of the technology. The economic characteristics include capital costs, O&M rates and revenue generated from the technology. The tables also include any adjustment factors (such as labor rates or energy prices) used in the Net Present Value calculations. The first tab, “Intro”, provides notes on the use of the data and the definition of each variable. Each subsequent tab is a different sector.
Each table presents break even price for each technology by region according to a discount rate and tax rate used to calculate the MAC curves. The analysis is conducted for the following combinations of discount and tax rates, respectively: from a social perspective – 4 and 0 percent; 5 and 0 percent; 10 and 0 percent; and from various industry perspectives – 10 and 40 percent, 15 and 40 percent, and 20 and 40 percent.

Appendix C: Marginal Abatement Curves (MACs)
The sector links below represent the five major methane sources for which abatement cost data are available and allow you to download a group of zipped spreadsheets for each sector. The "Total 5 Sectors" link provides a sum of the five sectors, a list of the countries covered and their regional groupings, as well as the Indicators.xls file which lists country-specific energy prices.

Files and Naming Convention (example for coal):
Below is a list of the files that should be un-zipped for the coal sector. The other sectors have the same file types and follow the same naming convention.
1) IMAC_Coal_C.xls Reports methane reference emissions and MAC data in absolute reductions in million metric tons of carbon equivalent (MMTCE) in the coal sector using a USD per ton of carbon equivalent ($/TCE) scale.
2) IMAC_Coal_%TCE.xls Reports MAC data in percentage reductions from the reference baseline in million metric tons of carbon equivalent (MMTCE) in the coal sector using a $/TCE scale.
3) IMAC_Coal_CH4.xls Reports methane reference emissions and MAC data in absolute
reductions in Gigagrams (Gg) of methane in the coal sector using a USD per ton of methane ($/TCH4) scale.
4) IMAC_Coal_%tCH4.xls Reports MAC data in percentage reductions from the reference baseline in Gigagrams (Gg) of methane in the coal sector using a $/TCH4 scale.
Notes for (3) and (4): 1 Gg of methane equals 1 Kiloton (103 metric tons) of methane. The $/TCE and $/TCH4 are on different scales, i.e., $10/TCE is not equal to $10/TCH4.
Contents of Each Spreadsheet:
Each spreadsheet represents a source sector (coal, manure management, natural gas, oil, or solid waste management). The first tab, IntroPage, provides notes on the use of the data. The second tab, SectorBaselines, provides reference baseline emissions for 2000, 2010, and 2020. The third tab, Sector Totals %, proves MAC data for all regions as a global total for that sector in data tables for 2010 and 2020. Each subsequent tab is a different region.
The MACs are represented in either percentage terms or absolute terms. The data is reported in either $/TCE or $/TCH4 (both in 2000 USD). MACs are constructed by applying the average cost of abatement technologies to the country/regional baselines in that sector or sub-sector.
Each table presents MAC data according to a discount rate and tax rate used to calculate the marginal cost of the abatement technologies. The analysis is conducted for the following combinations of discount and tax rates, respectively: from a social perspective – 4 and 0 percent; 5 and 0 percent; 10 and 0 percent; and from various industry perspectives – 10 and 40 percent, 15 and 40 percent, and 20 and 40 percent.
Within each table, the MACs also vary according to an energy price. The analysis tested the MAC sensitivity to changes in base energy price (from –50% to +200%), both for electricity and natural gas (see the Indicators.xls file for a detailed list of country-specific energy prices).
