Making emissions data more accessible

The ECCAD-GEIA portal provides access to global and regional inventories in a consistent format.

About GEIA

Quantification of chemical emissions into the air is a key step in explaining observed variability and trends in atmospheric composition and in attributing these observed changes to their causes on local to global scales. Accurate emissions data are necessary to identify feasible controls that reduce adverse impacts associated with air quality and climate, to track the success of implemented policies, and to estimate future impacts. GEIA is a community effort that builds bridges between environmental science and policy, by bringing together people, data, and tools to create and communicate the highest quality information about emissions. GEIA seeks to enhance access to emissions data, facilitate analysis to improve the scientific basis for emissions information, and strengthen the emissions community.

19th GEIA Conference - Postponed to April 15-17 2020



19thGEIA Conference

The Global Emission Initiative and Accelerating Social Transformations

15-17 April 2020

(Postponed from November 2019 due to civil unrest in Chile)

University of Chile, Santiago

Check out the Draft Agenda

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 19th Conference will focus on these questions:    How can emission research keep pace with and anticipate societal and technological change?  Are we anticipating where big changes in technology and behavior are occurring and what are the implications for emissions?

GEIA’s 19thConference will focus on advancing the scientific basis of emissions understanding and how this knowledge contributes to accelerating the societal transformations needed to address air quality and climate change. The 19th GEIA Conference will bring together the latest research on emissions, addressing energy and renewables, transportation, agriculture, natural sources, wildfires, waste and circular approaches  (retrofitting, reusing, recycling), climate change and COP25, top-down and satellite-based approaches, and integrated inventories for multiple sectors. The conference will address efforts worldwide to mitigate pollutants and discuss the impacts of changing emissions on air quality and climate.

The Conference will highlight the activities of GEIA’s Working Groups and will solicit input from the community about GEIA’s path forward by involving experts from all over the world. The Conference will help identify the important contributions that the GEIA community can make to the 25th session of the Conference of the Parties (COP 25) to the UNFCCC, expected to take place in January 2020 in Chile.

Summer School on Air Pollution Forecast Modeling in Santiago, Chile

28 October 2019 – 3 November 2019

Application Deadline  --  15 July 2019

We are pleased to announce that a summer school will be organized at the University of Chile in Santiago under the sponsorship of the PAPILA Project. The school is organized in conjunction with the GEIA conference that will take place in Santiago on 6-8 November 2019.

PAPILA (Prediction of Air Pollution in Latin America) is a project supported by the European Commission under the Marie Curie Program. It involves the participation of several research groups in European countries (Germany, France, Finland, Norway, Sweden, the Netherlands) and Latin American countries (Chile, Argentina, Brazil, Bolivia, Colombia, Venezuela, Mexico, Puerto Rico). 

The focus of the School will be on the development and use of air quality forecast models and will include the following elements:

·     Development of emission inventories at different spatial and temporal resolutions

·     Description of global and regional chemical transport models

·     Initialization of model predictions including data assimilation of space and in situ observations

·     Evaluation of model forecasts and comparison of model results with observational data

·     Treatment of large data sets

·     Assessment of impacts of air pollution

·     Mitigation policies and their impact on air quality

·     Dissemination of information.

A more detailed program and schedule will be communicated in the near future. 

Unfortunately, the School has not yet been able to obtain funding to support participants. Therefore, we will not be able to provide funding for travel and lodging, but we will offer affordable opportunities regarding lodging in Santiago. We hope that your home institution will be able to provide the resources needed to attend the school.

The school is open for about 30 participants. Priority will be given to

·     Early career scientists including post-docs involved in the PAPILA project

·     Early career scientists including post-docs involved in the GEIA project

·     Representatives of stakeholders and users of air quality forecasts.

To apply to the PAPILA School, please send an email to ina.doege@mpimet.mpg.deand provide the following information before the deadline of 15 July 2019:

1.     Full name

2.     Affiliation

3.     Current position

4.     Address of your host institution

5.     Telephone

6.     Email address

7.     Education:

8.     Work experience (5 lines)

9.     Motivation to attend the school (5 to 10 lines)

10.  Topic of particular interest in the school foci.

11.  Name of supervisor or advisor.


We hope very much that you are interested by the opportunity to attend lectures, participate in group discussions and meet professional colleagues at this occasion.
