Progress in the implementation of decision 1/CP.10 - Modelling tools to assess the impact of the
implementation of response measures
The following portal contains information on modelling tools that have been, or could be, useful in
assessing the impact of the implementation of response measures. This information is sourced from
outcomes of previous UNFCCC workshops, existing model databases and more general references and
sources. The amount of information available varied considerably across models and model
groups. The following structure is used:
- model name and main web page;
- name of organization and contact details;
- basic description;
- relevance in assessing the impact of response measures to climate change;
- geographical coverage;
- main area of application;
- examples of projects using the model;
- examples of other modelling projects and publications.
The descriptions are intended to be short and easily understandable. If users require further
information they can follow the web links or contact details.
The main criteria for selecting the models included in the web portal were:
Model structure and classifications: This faciltated the
identification of models covering the areas relevant for the analysis of the impacts of response measures
to climate change outlined above.
Geographical coverage: More importance was assigned to
models that cover all regions of the world. However, models with partial world coverage and
national (mainly large country) coverage are included if they are relevant to analysis of response
measures, or can provide good examples of exercises assessing national measures.
Documentation and evidence of maintenance: This information
provides evidence that the model is being maintained and can therefore reasonably be assumed to include
The database is divided into two sections, based on the focus of the modelling tools. The two sections
Integrated Assessment Models (IAMs) and Energy-Environment-Economy (E3)
models: For this context, IAMs and E3 models
are most relevant in assessing the impact of the implementation of response measures to climate
change, as they have a strong focus on socio-economic aspects. These models have detailed
sectoral and regional classifications that can be useful in assessing the impacts of
economic diversification and trade and spillover impacts. They are however less well equipped
to address technological development.
models: Energy models are particularly relevant for addressing energy efficiency and
analysing the impacts of new technologies. Many are also relevant to the analysis of different
pricing systems, for example through changes in taxation policy or subsidies. Generally,
however, their coverage of socio-economic issues is less well-defined.
