I don't think it's especially useful to think about emissions by country for the purpouses of thinking who can effect change. Any more than a small town resident should feel discouraged about voting in national elections. People need to be doing their part in all the reference groups they belong to, be it their field of expertise, their local government, international communities they belong to etc. "Act locally, think globally".
