Just to be clear, we are a midstream company, so we actually don't produce any oil and gas ourselves. We are primarily a transportation company and a power company.
I can talk very briefly, though, to the fact that we participate with a number of universities and industry associations and we fund a number of R and D initiatives to make sure that things like emissions monitoring and methane monitoring are done as efficiently as possible and that we're pushing the bounds on those all the time.
