Introduction

National Emission Inventory EPA prepares the National Inventory Report (NIR) and submits to

the UNFCCC. NIR 2005 submitted, contains time series inventory data to 2003. Total emissions of greenhouse gases in Ireland 67.5 million

tonnes CO2 equivalent in 2003. Emissions of CO2 accounted for 65.8% (44.415 million tonnes) of

the total 67.5 million tonnes. Emissions of CO2 from the fuel combustion activities and

Industrial processes accounted for 44.28 million tonnes of CO2 equivalent in 2003.

Introduction

Emissions Trading Unit (ETU) The Irish Environmental Protection Agency (EPA) is the

designated competent authority for Directive 2003/87/EC, of the European Parliament and of the Council of 13th October 2003, establishing a scheme for greenhouse gas emission allowance trading within the Community and amending Council Directive 96/61/EC.

The ETU within the EPA consists of the National Allocation Authority, National Competent Authority and the Emissions Trading Registry.

Introduction

Total CO2 emissions from the emissions trading sector, based on the average of verified 2002 and 2003 data was 20.62 million tonnes of CO2.

Currently 109 Greenhouse gas emissions (GHG) permits Total allocation per year to activities permitted by 31 March

2004 is 21.67 million tonnes (Mt) of CO2 equivalent. Average allocated was 97% of Business as Usual. National Allocation Plan 2005-2007

National Emissions Inventory

ETU data used in compiling the national emission inventory Verified CO2 emissions for 2002 and 2003 for the category fuel

combustion energy industries; public electricity, oil refineries and manufacture of solid fuels (briquettes).

Verified CO2 industrial process emissions from cement production, lime production, use of limestone for SO2 abatement at some plants and brick manufacture.

Activity Data Tonnes of lime produced and tonnes of limestone used in 2 lime

production plants. Tonnes of clay, shale and carbonates used to produce brick at 3

companies.

National Emissions Inventory

Activity Data Tonnes of clinker produced in the 4 cement

companies. Tonnes of limestone used for SO2 abatement at

some peat plants.

National Emissions Inventory. Future Improvements Planned.

The country specific emission factors and calorific values for fuels will be improved in future by taking account of all the batch fuel analysis results generated for calorific value and emission factor by large fuel combustion installations involved in the EU ETS. Batch analysis of fuels conducted by standard methods in ISO 17025 accredited test facilities will be available for 2005,2006 and 2007 for Coal, HFO/RFO, gas oil, natural gas and peat.

National Emissions Inventory. Future Improvements Planned.

2004 emissions data has not been verified to-date by the ETU of the EPA and was not used in compiling 2004 inventory data. However if this data becomes available the 2004 inventory data submitted in 2006 and 2007 can be revised.

A QA/QC Manual has been produced as part of implementing the National Inventory System. As part of this an investigation is planned to determine what if any QA/QC procedures data providers carry out prior to submission of data to the National Inventory Team.

Emissions Trading Unit

National Emission Inventory Data used Baseline verification of 2000-2003 CO2 emissions data from stationary

combustion sources. Emission factor t CO2/TJ for Kerosene, HFO/RFO and Gas Oil

from 2002 inventory data reported in 2004. Emission factors supplied in the National Inventory Report

included an oxidation factor. The ETU adjusted the emission factors so that the oxidation factor could be applied separately.

Net calorific values for kerosene, HFO/RFO and Gas Oil from 2002 inventory data reported in 2004.

Emissions Trading Unit, National Emission Inventory data used.

Country specific Emission factor, to be used by GHG permitted installations in the annual installation emissions report for 2005. This factor is for Kerosene, HFO/RFO and Gas Oil from 2003

inventory data reported in 2005. The ETU adjusted the emission factors so that the oxidation factor could be applied separately.

A country specific emission factor for Natural Gas has just been prepared by the emission inventory for the 2006 submission and will be available shortly to the ETU.

Country specific net calorific values for kerosene, HFO/RFO and Gas Oil from 2003 inventory data reported in 2005.

Emissions Trading Unit methodological issues

ETU requires a country specific emission factor for Coal and Pet. Coke based on current, representative, accredited data analysis.
