"Проект остаётся на бумаге" means in Russian that implementation of a project/plan has not been started. Is there some idiomatic way to say this in English?
"The project remains on paper" was the first solution that suggested itself, but when I tried googling it, about 17 of the first 20 hits were from Indian sites, which was troubling, because (as my previous experience tells me) not all that is acceptable in Indian English is considered good in the rest of the English-speaking world.
