IG3IS and Carbon Budget- Observations-based approach to support efficient mitigation of greenhouse gas emissions

Long-term measurements of Earth’s atmosphere show rapidly rising concentrations of greenhouse gases linked to human activities. Existing observing networks provide information on greenhouse gas emissions at the global scale, but alone are not sufficient to target, quantify and manage greenhouse gas emissions where they occur and can be controlled. Atmospheric measurement-based emission estimates developed within the framework of the WMO Integrated Global Greenhouse Gas Information System support the diversity of user needs. Examples to be presented follow established international standards and cover scales from facility to urban to national.
