Our too strict NOX standard is the problem in both cases, but it is especially harmful to diesel technology. It's like creating a standard that applies to everything but has an impossible limit on something only one power supply produces. What if there was a standard on heavy metal breakdown over time in say catalytic converters that diesels could easily meet and gas would have great difficulty. Same standard across the board so it's fair right? If diesels are going away globally it's only because they are following the US lead in killing them intentionally. If man made global warming is the biggest threat we face than NOx isn't the problem at all, if anything it helps with a cooling effect.
