GEIA 2023


20th GEIA Conference

Towards mitigating air pollutant and greenhouse gas emissions

21-23 June 2023

Hosted by the Royal Belgian Institute for Space Aeronomy Belgium

The Global Emissions InitiAtive (GEIA) provides stability in a rapidly changing world, by ensuring access to emissions data, facilitating emissions analyses, and strengthening the global community of emissions stakeholders. GEIA is a trusted source of the emissions information needed to address some of society’s greatest challenges. 

GEIA’s 20th Conference will focus on advancing the scientific basis of emissions understanding needed to more effectively mitigate air pollutant and greenhouse gas emissions. The Conference will bring together the latest research on emissions from all sectors and will discuss the impacts of changing emissions on air quality and climate. The conference will highlight the activities of GEIA’s Working Groups and GEIA’s collaborations with other international groups. The conference also will solicit input from the community about GEIA’s path forward by involving experts from all over the world. 

The Conference has 4 themes:

1.     Anthropogenic and natural emissions from local to global

2.     Top-down Emissions & Satellite Analyses

3.     Integrated studies of air pollutant and greenhouse gas emissions

4.     Mitigation efforts including real world examples
