Terraforming is started via a button on the World Detail view. The world must be surveyed and within your borders. Only habitable-type worlds, Tomb Worlds, and special Barren Worlds that have the rare "Terraforming Candidate" modifier can be terraformed.

It is possible to terraform inhabited planets if you have the {{iconify|Ecological Adaptation|24px}} technology. Doing so gives a -20% {{iconify|happiness}} penalty to the planet for the duration of the procedure.
 
 
The requirements for terraforming a world depend on the magnitude of the change. A change within the same climate (wet, cold, dry) is faster and cheaper than a change between climates. Barren worlds are considered to be closer to Dry or Cold Climate, depending on the subtype.

This article has been verified for the current PC version (2.7) of the game.

Terraforming is the act of changing the planet classification of a celestial body in order to make it more habitable for the empire's species. The base technologies requires significant Society Research society research to unlock and each terraforming project requires significant investments of Energy Credits.png Energy and time.

Terraforming requirements[edit]

Terraforming is started via a button in Planet Detail view. The world must be surveyed and within your borders. Only habitable worlds, and Barren Worlds that have the rare "Terraforming Candidate" modifier, can be terraformed. The expansion planner screen can be used to find these rare candidates.

It is possible to terraform inhabited planets if you have the Tech ecological adaptation.png Ecological Adaptation technology. Doing so gives a -20% Mod pop happiness.png happiness penalty to the planet for the duration of the procedure.

Ecumenopolis worlds are created via decisions rather than terraforming. They must be inhabited but pops do not suffer a happiness penalty during the process.

The following planet modifiers are always removed when terraforming a planet:

  • PM Bleak.png Bleak
  • Irradiated Irradiated
  • PM Hazardous Weather.png Hazardous Weather
  • PM Dangerous Wildlife.png Hostile Fauna
  • PM Wild Storms.png Wild Storms

If the planet is being terraformed into a Planet ai.png Machine or Planet infested.png Hive world the following modifiers are also removed:

  • PM Atmospheric Hallucinogen.png Atmospheric Hallucinogen
  • PM Atmospheric Aphrodisiac.png Atmospheric Aphrodisiac
  • PM Lush.png Lush
  • PM Natural Beauty.png Natural Beauty

When and if terraforming a planet to Hive or Machine World, keep in mind that all planetary features, excluding a few rare ones that give access to rare resources, will always be removed.

Cost reduction & speed[edit]

Terraforming cost can be affected by the following:

Source Cost Speed
Ap world shaper.png World Shaper ascension perk -25% -
Ancient Relics.png Secrets of the Baol empire modifier -15% -
Resolution ecolgical protection.png Ecological Protection resolution 4 +25% -
Resolution ecolgical protection.png Ecological Protection resolution 5 +100% -
Mod country terraform speed mult.png Shallarian Terraforming Knowledge empire modifier [1] -10% +20%
Menu icon policies and edicts.png Terraforming Gases edict - +50%
World shaper World Shaper ruler trait - +25%
