Let me know when you figure it out.
I imported my U.S. Insight to Sweden. Because Insights were never sold in Sweden, the Swedish Traffic Administration has no emissions information about my Insight. I was told that they would accept an E.U. Certificate of Compliance to determine emissions, but because my Insight isn't an E.U. model, I cannot get an E.U. Certificate of Compliance. I believe it was faxe who sent me a copy of the E.U. Certificate of Compliance for his Insight which was originally sold in Germany, but Sweden would not accept it because the Insight VIN encodes that mine is a U.S. rather than an E.U. model. Even though the U.S. has certified the CO2 emissions of my Insight at 80 g/km, Sweden won't accept U.S. emissions data.
Any car whose CO2 emissions are less than 100 g/km gets a registration fee discount. Sweden has classified my Insight as emitting something around 140 g/km, I believe based on the most similar model to mine sold in Sweden, a Honda Civic Hybrid. Therefore, Sweden won't grant me a registration fee discount
