Thank you.
My next question is directed more to you, Mr. Young.
You stated that projects could become carbon neutral by the year 2020, that you are optimistic, albeit realistic, about reaching this target. Can you tell me what technical challenges will need to be overcome in order to achieve this goal?
Furthermore, as I understand--and you can correct me if I'm wrong--you believe that internationally, it will be difficult to meet this goal before 2020.
