In this regard, I need some straightforward and rather urgent advice as the matter has reached a critical stage in the decision making process. There is general consensus on the economic benefits and energy security CNG use provides but there are still uncertainties regarding the finer points of engine compatibility, tariffs, fuel efficiency and environmental effects. The summary report moved by the transport department is terse which makes us believe that there is definitely some analytical work to be done, especially on the infrastructure deficit, costs involved and social impact.   </P> <P>To a large extent, the government is inspired by the Delhi experience and there are concerns about the current state of the environment there and whether any recent third party evaluation of the intervention in Delhi has taken place? If you could advise on this, or comment on whether you consider the move to CNG to have helped Delhi's urban sphere, it would enable us to make an informed decision. </P> <DIV>Thanking you in advance, </DIV> <DIV> </DIV> <DIV>Hassaan Ghazali<BR><BR>-- <BR>Legal and Institutional Reform Specialist (Acting)<BR>Urban Sector Policy and Management Unit (The Urban Unit)  <BR>Planning and Development Department, <BR>Government of the Punjab <BR><BR>A: 4-B Lytton Road, Lahore<BR>T: (+92 42) 921 3579-84 Ext.116<BR>M:(+92 345) 455 6016<BR>F: (+92 42) 921 3585<BR>Skype:halgazel<BR><A href="http://hghazali.googlepages.com/">http://hghazali.googlepages.com</A> </DIV></DIV></DIV></BODY><FONT face=Tahoma><FONT color=#0000ff> <P class=MsoNormal style="MARGIN: 0cm 0cm 0pt"><FONT face=Arial color=#000000 size=2>............................................................................................................................................................................................</FONT></P> <P class=MsoNormal style="MARGIN: 0cm 0cm 0pt"><FONT face=Arial color=#000000 size=2>DISCLAIMER</FONT></P> <P class=MsoNormal style="MARGIN: 0cm 0cm 0pt"><FONT face=Arial color=#000000 size=2></FONT> </P> <P class=MsoNormal style="MARGIN: 0cm 0cm 0pt"><FONT face=Arial color=#000000 size=2>This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to which they are addressed.
