9th International Symposium on
Non-CO2 Greenhouse Gases (NCGG9)

June 21-23, 2023, Amsterdam, The Netherlands



NCGG7 - 7th International Symposium on Non-CO2 Greenhouse Gases

Innovations for a Sustainable Future

November 5-7, 2014, Amsterdam, The Netherlands

Presentations Keynote Speakers and Photos online>>



Non-CO2 greenhouse gases include many substances, such as methane (CH4), nitrous oxide (N2O), fluorocarbons (CFCs, HFCs, SF6, etc), black carbon, aerosols, and tropospheric ozone (O3). These contribute significantly to climate forcing. Reducing non-CO2 greenhouse gas emissions is often more cost-effective than reducing CO2 emissions.

The scope of NCGG8 will be global challenges, and local solutions. The NCGG conferences pay attention to:

  • sources, sinks, and atmospheric processes of non-CO2 greenhouse gases;
  • mitigation options and emission reduction technologies and practices;
  • policies and measures, both in the public and private sectors; and
  • the science-policy-industry interface

Specific issues to be addressed at NCGG7 will include

  • Nitrogen-carbon cycling and interactions;
  • Short-lived climate forcers;
  • Air pollution versus climate change;
  • New emission reduction technologies;
  • The effectiveness of the Kyoto Protocol;
  • Policies on F-gases;
  • Corporate responsibility;
  • Short-term policies and long term policy objectives;
  • Action research and participatory integrated assessment;
  • Innovations for sustainable development.



We will invite submission of papers with respect to four themes, covering causes, effects and solutions of the environmental problems associated with non-CO2 greenhouse gases. These papers may report on science (from natural, social, technological or integrated sciences) and policy. 

Themes NCGG7Theme 1: Integration and Innovation

Theme 1, is the overarching theme of NCGG7 and aims at the integration and innovation. We seek for integration of innovative studies of sources of non-CO2 greenhouse gases, their effects and strategies to reduce these effects. This theme reflects in fact the overall aim of the conference: to synthesize new knowledge on non-CO2 greenhouse gases, in order to come to more effective solutions. Theme 1 includes contributions from Integrated Assessment studies, multi-and interdisciplinary approaches as well as transdisciplinary sciences. We particularly welcome contributions from the science-policy interface, and on corporate responsibility.

Theme 2: Sources, Sinks and Inventories  

Theme 2 will concentrate on sources, sinks and inventories, including innovations in emissions monitoring and reporting and verification of emission data. Papers presented in this theme will mostly be from the natural and technology sciences, although we also welcome contributions from integrated studies under this theme.

Theme 3: Atmospheric processes

Theme 3 will concentrate on atmospheric processes, and in particular on the physics and chemistry related to the radiative aspects of the atmosphere, including monitoring of concentrations of non-CO2 greenhouse gases, atmospheric processes including the relations between greenhouse gases and other air pollutants (e.g. aerosols). Contributions to this theme may include innovations in models and in atmospheric measurements.

Theme 4: Policy Implementation 

Theme 4,  will concentrate on policy implementation, including mitigation and adaptation. Policy and implementation issues may include assessments of implementation programs for reduction of non-CO2 greenhouse gas emissions and innovative approaches in policy implementations. Contributions within this theme will be from both natural sciences (e.g. reporting on new emission reduction technologies) and social sciences (e.g. on the economic or institutional feasibility of environmental measures). Contributions on technological issues and industries’ perspectives are welcomed, as well as discussions on the realization of policies.
