NCGG9

9th International Symposium on Non-CO₂ Greenhouse Gases

Identify game changers and verify impact

June 21-23, 2023, Amsterdam, The Netherlands

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 the 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.

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