TBH I don't know enough about it to say yes or no - perhaps a fairly complex issue, so to say frack or not frack is too simplistic.

I do know per capita GHG emissions in the US and my country NZ are some of the highest in the world and its not sustainable or equitable.

For the USA to adopt Trumps drill and burn attitude will make it very difficult to reasonably expect other nations to reduce GHG emissions.
