# Carbon System

* Every time a [mining-machine](https://craftdefi.gitbook.io/craftdefi-whitepaper-v0.5.0/4qyEUpv3t4fyVcgcy7Tb/gameplay/building/mining-machine "mention") is activated,  'carbon' will gradually increase.

* If carbon exceeds the allotted limit on each land, the Power of each machine will gradually decrease until production is halted.

* Every 15 minutes, carbon will decrease automatically based on the value of 'air regeneration' within a land. Air regeneration can be improved to further reduce carbon by building certain [utility-building](https://craftdefi.gitbook.io/craftdefi-whitepaper-v0.5.0/4qyEUpv3t4fyVcgcy7Tb/gameplay/building/utility-building "mention")\\

* Carbon will be reduced by 50% of its capacity every 24 hours.

* Carbon Capacity can be increased upon building certain [utility-building](https://craftdefi.gitbook.io/craftdefi-whitepaper-v0.5.0/4qyEUpv3t4fyVcgcy7Tb/gameplay/building/utility-building "mention")

* Certain [disaster](https://craftdefi.gitbook.io/craftdefi-whitepaper-v0.5.0/4qyEUpv3t4fyVcgcy7Tb/gameplay/land/disaster "mention") can also lead to the reduction of Carbon\\
