The United States had 65%, Russia had 8%, and Canada had 3%, thus 75% of all pipeline were in these three countries. "Pipeline and Gas Journal"'s worldwide survey figures indicate that of pipelines are planned and under construction. Of these, represent projects in the planning and design phase; reflect pipelines in various stages of construction.
