Peru’s Greenhouse Gas Emissions Inventory

Abstract

This paper presents the results obtained in the estimation of Peru’s Greenhouse Gas Emissions Inventory for 1990, a task performed under the scope of the “Peru Climate Change Country Study,” sponsored by the U.S. Country Studies Program. To carry out the inventory assessment, emission sources were divided into two major elements: energy and non-energy. The energy sector considers extraction, conversion, and energy end-use activities. The energy end-use activities include industry, transport, residential-commercial, mining-metallurgical, fishing, public services, and agriculture-agroindustry. The non-energy sector considers the following areas: agriculture, industrial processes, land-use change and forestry, and waste. The IPCC Guidelines for National Greenhouse Gas Inventories were used in preparing Peru’s inventory. Emissions in the energy sector were as follows: carbon dioxide from fossil energy consumption totaled 18,719 Gg CO2; methane from biomass, coal production, and oil and gas systems totaled 83 Gg CH4; carbon monoxide from biomass totaled 623 Gg CO; nitrous oxide from biomass totaled 0.5 Gg N20; and oxides of nitrogen from biomass totaled 11 Gg NOx. Gross emissions of CO2 from biomass consumption were 18,590 Gg CO2 and emissions from oil bunkers were 257 Gg CO2, but these were not included in the total CO2. Emissions in the non-energy sector were as follows: 84,222 Gg of CO2; 1,293 Gg of CH4; 10,849 Gg of CO; 6.2 Gg of N2O; and 149 Gg of NOx.
