The Society for Planet and Prosperity (SPP) and the Department of Climate Change (DCC) of the Federal Ministry of Environment have trained climate change Desk Officers from the 36 states of the federation on Greenhouse Gas Inventory Compilation and Emission Reporting. The training followed the release of the 2025 Subnational Climate Governance Performance Rating and Ranking and is designed to strengthen technical capacity, improve data quality and reporting standards, and deepen federal–state collaboration on emissions accounting and reporting.
In her opening remarks, the Director of DCC, Dr Iniobong Abiola-Awe, reminded the Desk Officers of the importance of prioritizing the fight against climate change at the subnational level and maintaining accurate data collection methods.
Dr. Abiola-Awe emphasized the need to foster inter-agency collaboration and align budgets with national and state priorities. She encouraged participants to collaborate, share experiences, and commit to practical actions to strengthen national climate capabilities and contribute to regional and international commitments.
“As you embark on this journey of capacity building, I encourage the spirit of collaboration and openness, share experiences respectfully, and commit to practical and result-oriented action,” she said.
The training, which was facilitated by SPP’s Executive Director, Mr. Edwin Oghenemere Orugbo, covered the IPCC framework, emission accounting principles, and the process of data collection and estimation.
Participants were encouraged to engage in practical sessions and interactive discussions to gain more in-depth knowledge of the topic.
In his presentation, Mr Orugbo emphasized the importance of climate action and the basics for attracting climate finance. He also discussed the gases of concern, including carbon dioxide, methane, nitrous oxide, and fluorinated gases, and the need to consider all greenhouse gases when compiling inventories at the state level.
According to Mr Orugbo, the IPCC greenhouse gas inventory framework and emission accounting principles consider four main source categories: energy, industrial processes, agriculture/forestry, and waste, along with the core principles of transparency, accuracy, consistency, and comparability. He detailed the process of data collection and emission factor calculations, including a basic calculation formula for determining greenhouse gas emissions.
Mr Orugbo stressed the need to capture metadata for each dataset and use reliable sources for emission factors, such as the UNFCCC and IPCC websites. The discussion highlighted the role of subnational inventories in enabling data-driven climate policies and the importance of collaboration for sustainability and transparency.
The participants shared their opinions on the necessary institutional arrangements, including legal frameworks, data sharing protocols, and partnerships between state MDAs. They outlined technical requirements, including data management systems, estimation tools, and field monitoring equipment, as well as the need for a dedicated Monitoring, Reporting, and Verification coordinator and sector-specific data officers. They also highlighted the importance of proper quality assurance/quality control procedures and metadata management, while addressing capacity building needs for training on IPCC methodologies and data collection procedures as some of their immediate needs to ensure that they can develop and manage GHG emission inventory at the subnational level.
Responding to their queries on behalf of DCC, Dolapo John, Principal Scientific Officer at DCC, promised the department’s readiness in supporting the states with the capacity needs, using the IPCC software.
The greenhouse gas inventory compilation and emission reporting session is one of a series of capacity-building trainings organized by the Society for Planet and Prosperity to equip subnational Desk Officers with the right knowledge to ensure climate resilience is sustained at the subnational level. This session was moderated by Mr Timothy Ogenyi, Senior Policy Analyst (Climate Change), SPP.
Next in the series of SPP’s intervention on capacity building for the subnational are trainings on “Designing Effective Monitoring & Evaluation Systems for State Climate Action” and “Climate Finance.” SPP is committed to this laudable initiative with support from the European Climate Foundation (ECF).
