Data and methods

Burundi, as a Party to the UN Framework Convention on Climate Change (UNFCCC)committed to improving the monitoring, measurement and transparency of its greenhouse gas (GHG) emissions. To meet this commitment, the country is regularly developing and updating its National GHG Inventory, which is an essential basis for guiding climate policies and supporting the implementation of nationally identified contributions (NDCs).

Burundi mobilizes several categories of data to estimate its GHG emissions:

• Agricultural data : cultivated areas, number of livestock, farming practices, agricultural inputs (fertilizers, pesticides).

• Forest data and land use forest cover, deforestation rate, reforestation, land-use change.

• Energy data Wood energy consumption (coal, firewood), imports and consumption of petroleum products, electricity generation and consumption.

• Waste data : volume of solid waste produced in urban areas, management of domestic and industrial wastewater.

• Industrial data Production of materials (cement, bricks), use of solvents, small craft units.

Burundi uses IPCC Guidelines, mainly:

• Tier 1 method (default): application of standard emission factors (provided by the IPCC), adapted to countries where local data are limited.

• Tier 2 method (where national data are available): use of specific emission factors in Burundi, e.g. cattle farming or biomass consumption.

Calculations are made in three main stages:

Collection of activity data : Amount of coal consumed, hectares of rice grown, litres of fuel used, etc.

Application of emission factors (IPCC or country-specific): Example: 1 tonne of burnt charcoal = X tonnes of CO2e.

Conversion to CO2 equivalent (CO2e) : Consideration of the global warming power (GWP) of the different gases (CO2, CH4, N2O).

• • Examples of GWP (IPCC AR5):

    • CO2 = 1

    • CH4 = 28

    • N2O = 265
