GEIA's efforts in emissions analysis are advanced by working groups on specific topics, overarching activities, and through collaborations with other initiatives, science teams, and agencies. Additional working groups will be formed as GEIA-facilitated dialogs identify evolving emissions challenges and establish paths for translating these challenges into new emissions databases.
GEIA Working Groups - Updates
AFRICA EMISSIONS WORKING GROUP
Contacts : Cathy Liousse, Mogesh Naidoo, Sekou Keita
·Create a networkon emissions over Africa with local experts, international group representatives and decision makers.
·CreateAfricanemission database at the regional/country/city scales on basic informationsand inventories
·Develop and evaluate a continental wide African emission inventory, with the most recent DACCIWA inventory as a baseline and local informations.
Organizing the sharing of emissions methodology and data and promoting community efforts in emission inventory development for China. Chair: Kebin He; GEIA Steering Committee Member: Yuxuan Wang
GEIA NMVOC Emissions Working Group
GEIA’s Non-Methane Volatile Organic Compounds (NMVOC) Emissions Working Group is coordinating efforts on the evaluation and improvement of the representation of in emission inventories, including speciation, sector contributions, and total emissions. The Working Group is currently focused on a review of NMVOC speciation and source sector contributions. The review will examine existing analyses comparing inventory emission ratios of NMVOCs to CO to measured ratios of these species in urban areas around the globe. More details of this activity can be found here. If you are interested in joining the WG or participating in this activity, please get in touch!

Latin America and Caribbean GEIA Working Group
Contacts: Nicolas Huneeus, Laura Dawidowski, Néstor Rojas
Priorities of the LAC-GEIA Working Group are:
• Building/developing/improvement of emission inventories considering specific conditions in Latin America, for each sector with high spatial resolution in particular for cities.
• Build a community where information, data, knowledge and experience can be exchanged contributing to the development/improvement/evaluation of inventories.
• Evaluate and check consistency of inventories and base information.
• Create a regional unified database including all information (inventories and base information) and provide the tools to access it. Develop strategies to overcome information shortage.
• Identify key areas of needed research for emissions estimation for South America.
• Create a link to decision makers, public policy and funding institutions.
The WG will also inform GEIA’s global emissions community about the best and latest emissions information in the region, and provide stronger connections between the global and regional atmospheric scientific and policy communities.
Urban Emissions Working Group
Contact: Leonor Tarrasón
GEIA’s Africa Emissions WG is promoting community efforts in emission development for Africa. The working group consists of a list of members, which is in construction, to create a network on emissions with strong connections between experts (African and non-African) on African emissions, representatives of international groups and projects such as IGAC, IGAC-Africa ANGA, WMO, ILEAPS, AMIGO, MAP-AQ, IBBI, DEBITS, PASMU, LIA-ARSAIO etc .. and regional decision makers. The WG is currently planning
- To evaluate African-specific emission inventories.
- To consider specific emissions in Africa, for each sector from regional to city spatial resolution.
- To create a regional database including local informations on fuel activity and consumption, emission factors and emission inventories. This database will deal with sources for present, historical and future emissions including mitigation scenario.
- To develop a continental wide African emission inventory, with the most recent DACCIWA inventory as a baseline and local informations.
- To organize training sessions on emissions in Africa
