How will dramatic changes in global sources of energy influence emissions?  How will more efficient use of energy alter emissions levels?  How will changes in agricultural practices modify emission levels?  How does economic development in Asia affect emissions? What new observational or modeling tools can be used to analyze emissions?

These questions and many others will be addressed in the GEIA online forum on new emission challenges.  The forum discussions will focus on identifying, quantifying, and tracking new emissions challenges.  GEIA registered users can participate in the forum which will be coming online soon. Discussion topics will be moderated by GEIA Steering Committee members or their designates.

The following references provide examples of the challenges involved in characterizing emissions from emerging sources or regions, highlight changes in our understanding of emissions from existing sources, or demonstrate innovative approaches to emissions analysis. We welcome other references that highlight new emissions challenges; please submit your ideas via the GEIA Web Site Forum.
