Measurement guidelines

A major milestone on the path to developing the G-res Tool was reached with a UNESCO/IHA Greenhouse Gas Status of Freshwater Reservoirs project in 2010. This concluded with the launch of the GHG Measurement Guidelines for Freshwater Reservoirs, a landmark publication and standard on measuring emissions from reservoirs.

The guidelines offer a comprehensive tool to assess the GHG status of freshwater reservoirs, including definitive guidance on the measurement and qualification of emissions resulting from the formation of reservoirs. The guidance covers:

  • Concepts and processes involved in making such measurements
  • The approach to conducting field measurements
  • Guidance on calculating results

With the concept of global application being at the forefront of the development of the GHG Measurement Guidelines, IHA and its partners have ensured that the methodology contained within the publication is applicable to all climate types and reservoir conditions.

By providing the tools required to measure GHG emissions in a selected set of reservoirs, the intention is to ensure that the results gained will be utilised to develop predictive tools, thereby avoiding the necessity of intensive field measurements in the future. It is anticipated that results shared from the use of these guidelines will contribute to this.
