No, it's not. It's just like any other mana added to your mana pool. It goes away as soon as it's spent, or when the current phase or step ends.
Are you confusing mana with land? Because if so, let's establish this right now:
Lands are not mana. Mana is not land.
Mana is produced by various spells and abilities, including the abilities of lands.
When Burning-Tree Emissary's triggered ability resolves, you add one red mana and one green mana to your mana pool.
This is the equivalent of tapping a Mountain and a Forest for mana. You aren't physically adding any cards to the battlefield -- you're merely getting mana, which you can either spend to cast spells/activate abilities, or let it be emptied from your mana pool at the end of the current phase or step if you decide not to use it.
