The Scientific Director of BC3, Prof.Maria Jose Sanz and Dr. Agustin del Prado, Senior researcher at BC3, participated in the IPCC “Second Lead Author Meeting for the Elaboration of the 2019 Refinement to the 2006 IPCC Guidelines for National Greenhouse Gas Inventories”, that tool place in Victoria Falls, Zimbabwe (25 Sep – 28 Sep 2017).

Prof. Maria Jose Sanz is acting as Coordinating Lead author and Dr. Agustin del Prado as Lead Author.

The First Lead Author meeting was held in Bilbao (7-14 June 2017) and was hosted by BC3.



The meeting work on the preparation of the new Report 2019 Refinement to the 2006 IPCC Guidelines for National Greenhouse Gas Inventories (2019 Refinement).

The aim of the 2019 Refinement is:

to provide an updated and sound scientific basis for supporting the preparation and continuous improvement of national greenhouse gas inventories;
not to revise the 2006 IPCC Guidelines, but update, supplement and/or elaborate the 2006 IPCC Guidelines where gaps or out-of-date science have been identified.

The format and structure will be the same as the 2006 IPCC Guidelines (i.e. Overview Chapter and 5 Volumes) so as to make it easier for inventory compilers to use the 2019 Refinement in conjunction with the 2006 IPCC Guidelines.

Additional Information

The Intergovernmental Panel on Climate Change (IPCC) was created in 1988 to deliver comprehensive reviews on the scientific, technical and socio-economic state of knowledge of climate change, its causes, possible repercussions and response strategies.

Its contribution to understanding climate change has been fundamental to creating global agreements on common goals, the last of which, the Paris Agreement, aims to strengthen the global response to the threat of climate change, including by holding the increase in the global average temperature to well below 2 ºC above pre-industrial levels and pursuing efforts to limit the temperature increase to 1.5 ºC above pre-industrial levels, recognizing that this would significantly reduce the risks and impacts of climate change. Governments agreed to set Nationally Determined Contributions to reach this goal, which will be reviewed regularly.

In its last report, the Fifth Assessment Report, the IPCC found that anthropogenic emissions of greenhouse gases, such as carbon dioxide, methane, and nitrous oxide, are extremely likely to have been the dominant cause of observed warming since the mid-20th century. It found that limiting climate change would require substantial and sustained reductions in greenhouse gas emissions.

The IPCC is organised in three thematic Working Groups, and a Task Force on National Greenhouse Gas Inventories (TFI). The TFI is responsible for development of internationally-agreed methodology for countries to estimate its emissions of greenhouse gases (GHG). The latest comprehensive guidelines on such methodology produced by TFI were produced in 2006, titled the “2006 IPCC Guidelines for National Greenhouse Gas Inventories” (2006 IPCC Guidelines). The 2006 IPCC Guidelines are used by many countries in the world to estimate and report their national GHG emissions.

At its 41st Session in February 2015, the IPCC decided to produce a Sixth Assessment Report (AR6). At its 42nd Session in October 2015 it elected a new Bureau to oversee the work on this report and Special Reports to be produced in the assessment cycle. At its 43rd Session in April 2016, it decided to produce three Special Reports, a Methodology Report and AR6.
