That was true in the mechanical injection days. Diesels have long been way better than gassers in regards to greenhouse gasses due to the fact that they burn way leaner. With the new "clean" diesels, they're on par in regards to nox and particulates with better engine and fueling management systems, urea injection and diesel particulate filters.
