What makes you think they are no better? The Euro standard is the same as it measures engine output. So a hybrid bus with a Euro 5 engine has the same target as a Euro 5 diesel bus - usually measured at g/kWh. As hybrids spend some time on electric power their engines use less energy per mile than a pure diesel so the absolute emissions per mile should be lower on a hybrid.
