terms of their impact on cumulative emissions rather than just annual
emissions.&nbsp; If possible, can you refer me to definitive studies and policies
that address this issue?&nbsp; Also, whether folks are aware of cost/benefit
spreadsheet tools that may provide useful framework to undertake such an
analysis of measures.&nbsp; Thanks.&nbsp; Jeff <o:p></o:p></span></font></p>
