urlpackage and embed the URLs as\url{www.cop21.gouv.fr/...}– egreg Feb 04 '16 at 10:22\documentclasscommand, has a minimal preamble and then\begin{document}...\end{document}. Unless the problem is a compilation error, the code should compile and be as small as possible to demonstrate your problem. This makes it much easier for people to help you --- and much ore likely that they will! – Feb 04 '16 at 10:29\\at the end of a paragraph, but there are no\\here. It's possible that it is your url (you should do as egreg says and use url package in any case, for those) – David Carlisle Feb 04 '16 at 13:43
