of new cleanup technologies based on nanotechnologies on the basis
of the precautionary principle. I may not have been exactly on the

protecting public health and the

We try to stay away from politics on the blog, so we were reluctant to take up the Sierra Club's recent report concluding that if Donald Trump became president he would be unique among world leaders in his refusal to acknowledge climate change.
With the recent finding that greenhouse gas emissions from certain aircraft engines endanger public health and welfare, the EPA must promulgate aircraft engine emission standards under CAA Section 231.
