they are found in two main regions.
The most often thought about is the northern forests. There, the summers are very short, and nutrients hard to come by, so they simply do not have the time or ability to grow a whole new set of leaves every year.
In more southern latitudes, summers are often hot and dry. Keeping broad leaves on the trees would put an enormous strain on them, so in the summer they shut down. Again, they have the leaves ready to go as soon as conditions are suitable.

possibly that the needles are able to retain their moisture year long and don't have the need of shedding them. not sure but sounds good.
