Background

In June 2015, the 17th World Meteorological Congress requested a plan for an Integrated Global Greenhouse Gas (GHG) Information System (IG3IS).  In December 2015, the UNFCCC nations forged the Paris Agreement, codifying the idea of nationally determined contributions (NDCs). These nationally appropriate pledges to reduce GHG emissions serve to unify all nations in an effort to slow and then stop global climate disruption.  These pledges vary by nation, geographical region, and economic ability.  Regardless of the strategies and mechanisms applied, the ability to implement long-term policies and manage them effectively will require consistent, reliable, and timely GHG emissions information.  A framework capable of accepting and promoting a range of advanced GHG emission quantification capabilities could improve the quality of and confidence in GHG emission inventories.  The IG3IS will be such an information source and framework that will join atmospheric GHG composition and flux measurements and other observations (the “top-down”) with spatially and temporally explicit socioeconomic emission inventory data (the “bottom-up"). The combination of these data sources will better inform emission reduction policies and measures.

IG3IS Statement

IG3IS is envisioned as an observationally based information system for determining trends and distributions of GHGs in the atmosphere and the ways in which they are consistent or not with efforts to reduce greenhouse gas emissions. This is being done already on a global scale through existing networks, but currently provides only a modicum of useful information at the spatial scale of nations and regions managing emissions and offsets.  The IG3IS effort is aimed at improving the granularity of observations and analyses, in order to support the planning and management of Intended Nationally Determined Contribution (INDC) mitigation efforts by nations.  IG3IS is not designed to check compliance with regulations, but rather to provide information on policy- and management-relevant scales and ensure that the information provided is consistent with a global network of high quality observations and models.
