Guidance Tools

Types of Guidance Tools

The Guidance Tools in this Toolbox come in three forms:

  • Type I – General Information & Reference
  • Type II – Model/Methodology Descriptions with Examples
  • Type III – Messages for Improving Practice.

The first type of Guidance Tools is designed to provide background knowledge and complement other existing sources of information. The second type goes into more detail regarding the models and methods available that can be used to assess climate change effects. These Tools include sections on data needs, assumptions and limitations, and linkages through to other Tools in the Toolbox, including the Decision Tools described in the next section. The third type provides information on integrating climate change assessment information into the council planning and operations.

The tables below give a brief description of each of the Guidance Tools available in the Toolbox.
