Comment by then

scanning over the article > "clean" in the headline and "green" first paragraph leaves me confused, also the two following paragraphs are titled "clean and green" and then talks about fines...followed by "a 'fine' city" (pun intended?). So in what way does punishment affects 'green' solutions? What solutions are you looking for? In what way would incentives work? 'Mentality change' is also an interesting one...Too many questions
