International Nitrous Oxide Emissions and Mitigation for EMF 21

 
Below is the Nitrous Oxide data set for the EMF 21 working group. The attached spreadsheets contain 1990, 1995, 2000, 2010 and 2020 reference emissions for all N2O sources as well as marginal abatement curves (MACs) for 2010 and 2020 for adipic and nitric acid production.  All baseline data is reported by region and by sector.
 
Reference emissions for 2000 should be used to benchmark your model's emissions to that year.  The MACs should be incorporated into your model for the multi-gas mitigation analysis based on the study's scenarios.
 
The links below represent total nitrous oxide baseline emissions. A list of the countries covered and their regional groupings are included in the methane zip file.  (See the section on methane MACs).

Baseline Data:

The following spreadsheet contains N2O baseline emissions for 1990, 1995, 2000, 2010 and 2020 by region by sector.

The reference emissions are based on estimates in two EPA reports and the national communications:
 
(1) “Non-CO2 Greenhouse Gas Emissions from Developed Countries: 1990-2010” available at http://www.epa.gov/ghginfo/reports/index.htm
 
(2) Draft “Non-CO2 Greenhouse Gas Emissions from Developing Countries: 1990-2010” available via email.  If anyone would like to a copy please contact me.

Marginal Abatement Curves for N2O:
 

The following spreadsheets contains the corresponding 2010 and 2020 marginal abatement curves for adipic and nitric acid production.

 ADIPIC AND NITRIC ACID PRODUCTION SECTOR

In each spreadsheet, the marginal abatement curves (MAC) are represented in either percentage terms or absolute terms.  The data is scaled on either $/TCE or $/tN2O.  MAC curves in these data sets are constructed by applying the average cost of mitigation technologies to the country/regional baselines.

Within each spreadsheet, the spreadsheet is divided into regions (each tab is a different region).  For each region (tab), the data is presented in tables.  There is a set of tables for 2010 and 2020 on the same tab for each country.

Each table presents the MAC data according to discount rate and tax rate used to calculate the cost of the mitigation 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 vary according to the energy price. Because of the high sensitivity to energy prices, the analysis tested the MAC sensitivity to changes in base energy price (from –50% to +200%), both for electricity and natural gas.

All costs and benefits are expressed in constant 2000 US dollars.

For further information on the methodology please refer to the methodology for the methane marginal abatement analysis (methodology memo listed on the methane page).  The following is a list of the technologies used in the analysis.

Naming Conventions:

IMAC_IndustrialN2O_TCE.xls refers to the spreadsheet which reports IMAC data (as opposed to baseline data only), in percentage reductions for the baseline in terms of carbon equivalent for the adipic and nitric acid production sectors using a scale of $/TCE.

IMAC_IndustrialN2O_%tCH4.xls refers to the spreadsheet which reports MAC data in percentage reductions from the baseline (in terms of Gg of N2O)  for the adipic and nitric acid production sector using scale of $/tN2O.  Note that this is on a different scale than above so does NOT have the same percentage reductions at $10, for example.

IMAC_IndustrialN2O_C.xls refers to the spreadsheet which reports the IMAC data in absolute reductions of methane in carbon equivalent in the adipic and nitric acid production sector using a $/TCE scale.

IMAC_IndustrialN2O_CH4.xls refers to the spreadsheet which reports the IMAC data in absolute reductions of N2O in the adipic and nitric acid production sector using a $/tN2O scale.
