Greenhouse Gas Inventory

The GHG Inventory Division has a vision to ensure that Nigeria develops in harmony with the environment by satisfactorily providing a sustainable policy framework and enabling environment for the implementation of the UNFCCC and Kyoto Protocol, as well as, any other climate change guidelines, laws and control in Nigeria.

Our core mandate at the GHGI Division, is to develop a National GHG Inventory System for National Communications to UNFCCC, Update the annual GHG Inventory database and to develop scenario(s) for reducing future emissions.

Specific activities in achieving our mandate include but not limited to:

  • Strengthening of the National Inventory for Greenhouse Gas emissions.
  • Annual update of the Greenhouse Gas Inventory Database.
  • Coordinate National Digital Hub for GHG Inventory Management System (Data Collection, Analysis and Archiving).
  • Calculation of existing Inventory emissions in line with IPCC Guidelines.
  • Implement and improve the National GHG Inventory Plan.
  • Collaborate with relevant National and International organizations in the areas of: Capacity Development, and Research to support National planning and International Reporting Requirements under the UNFCCC.
  • Develop programmes through Capacity building Workshops/ Seminars on GHG emissions/ Sources/ Scenarios/ emission reduction.

The objective of the United Nations Framework Convention on Climate Change (UNFCCC) is to stabilize greenhouse gas emissions concentration in the atmosphere to reduce the risks we will face from future climate change.

Under the umbrella of the UNFCCC, there are three (3) reporting requirements: National Communications, Biennial Update Reports and Nationally Determined Contributions, in which NC and BUR are under the purview of GHG Inventory Division, where Nigeria is required to:

  • Provide data on its greenhouse gas emissions on annual basis.
  • Submit National Communications periodically, reporting on progress in reducing its net greenhouse gas emissions.
  • Enact policies and measures to address greenhouse gases.
  • Access and document the financial and technological resources provided to it as a developing Country Party to help address climate change.
  • Conduct and document its systematic observations of the climate system and research on climate change and its impacts.

National Communication (NC) is a national document prepared by parties to the UNFCCC every 4 years informing the Convention of Countries emission by sources and removal by sinks of all greenhouse gases in the various sectors of the economy while Biennial Update Report is also a national document prepared every 2 years for the purpose of updating the NC, as well as to report the technical and financial support received.

Nigeria submitted its 1st National Communication in 2003, 2nd National Communication in 2014 and 3rd National Communication in 2020. Nigeria’s first BUR (BUR1) was submitted in 2018 and presently, Nigeria has commenced preparation of the second Biennial Update Report (BUR2).

  • Participated at the seventh workshop of the facilitative sharing of views (FSV) for non-Annex I Parties held in June, 2019 in Bonn, Germany where Nigeria’s first Biennial Update Report (BUR1) was subjected to review.
