Is it possible for a planet to have an area saturated with lava but at the same time is still habitable to humans and other lifeforms?

An area of my planet is very saturated with lava. Being quite similar to the Siberian Lava Traps, it is essentially a lava sea. This lava "sea" area isn't necessarily all lava however, as there are actually some rocky islands dotted about the sea.

Life, always finding a way, has seeded themselves on these islands. They've even achieved sentience. Being incredibly heatproof however, costed them their looks, the other sentient races labeling them "demons". They're quite nice though, just misunderstood.

For some reason, the lava doesn't emit any greenhouse gases nor does it emit gases not conducive to life. That's why the rest of the planet is very Earth-like. Only being near to that area would you start to feel the heat.

Is there any rock or metal that this molten sea should be composed out of, so that it won't emit greenhouse and poisonous gases?
