Ninth International Symposium on Non-CO2 Greenhouse Gases

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 importance of this conference is increasing every new event as our window for action in the climate dossier is closing rapidly. Fortunately, public awareness that we need to act now is growing. With that awareness “game changers“ are proposed that need scientific evaluation to distinguish realistic and valuable concepts from what is known in The Netherlands as “ride a bike in the sky” ideas.

The scope of NCGG9 will be to identify game changers and evaluate impact. The status of global affairs in terms of non-CO2 GHG issues is evaluated with:

  • observation of the current state and trend in the atmosphere, on multiple spatial scales;
  • using that information in models to integrate and upscale the available measurement data;
  • running models for scenario analyses predictions;
  • feeding the results from measurements and models to inventories;
  • use inventories and models to inform and predict;
  • discuss potential adaptation and mitigation options and policies;
  • make scenarios with social economic parameters and integrated environmental assessment;
  • discuss the general picture and results with stakeholders, to identify potential game changers with decision makers, industry, the financial & insurance sector, NGOs and international organizations.
