News: IG³IS launched an open public review of the “IG³IS Urban Greenhouse Gas Emission Observation and Monitoring Best Research Practices”. Comments and reviews should be submitted to gaw@wmo.int on or before January 31st, 2022.  Include “IG3IS Urban Guidelines Submission” in the subject line.

IG³IS Introduction

IG³IS is envisioned as an observation-based information system for determining trends and distributions of greenhouse gases (GHGs) in the atmosphere and the ways in which they are consistent or not with efforts to reduce GHG 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 Nationally Determined Contribution (NDC) mitigation efforts by nations at both the national and sub-national levels.  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.

IG³IS Mission 

IG³IS looks to serve users (decision-makers) who are able to take action to reduce emissions of greenhouse gases (GHGs) and pollutants that reduce air quality. This service is based on existing, successful methods and use cases for which the scientific and technical skill is proven. The ultimate success criteria are that the IG³IS information is “used” and guides valuable and additional emission reduction actions, building confidence (and skill) in the role of atmospheric composition measurements as an essential part of the climate change mitigation environmental remediation tool kit.
