Methodology (IPCC)

Burundi applies the highest international standards to assess the progress of its Nationally Determined Contribution. This page details the approaches, models and assumptions used to calculate greenhouse gas (GHG) emissions and removals

Burundi's accounting approach is aligned with the transparency requirements of the Paris Agreement (Decision 18/CMA.1):

• Calculation tool : Software IPCC Tool 2006 (IPCC).

• Guidelines : IPCC Guidelines 2006 and their Refinement of 2019.

• ICTU approach : Reporting incorporates Clarity, Transparency and Understanding of the CDN (Information for Clarity, Transparency and Understanding).

To compare the impact of different gases, Burundi uses the values of 5th IPCC Assessment Report (AR5) over a period of 100 years:

• General approach (Level 1) : For the majority of sectors, IPCC default emission factors (EFs) are used due to the lack of specific national data.

• Advanced approach (Level 2) : Sector Forestry and Other Land Allocations (FAT) benefits from clean emission factors, using approach 2 of the Tier 2 method, allowing greater accuracy on forest carbon stocks.

Climate projections are based on socio-economic assumptions provided by theINSBU (GDP, population growth and wood energy needs).

The basic formula used for the calculation of avoided emissions is:

E = DA x FE (Where E = Emissions, DA = Activity data, FE = Emission factor).

Progress is measured by deducting emissions from mitigation actions from baseline values BAU (Business As Usual).
