What this project does

Each player in Red Carbon has their own simulated world, represented as an EXIOBASE input-output (IO) table. Red Worlds applies the player’s daily action to their world and returns updated emissions figures.

The three action types:

• BUILD — construct new low-carbon capacity; CapEx spread over a build period
• SWAP — shift a fraction of one technology’s demand to a cleaner alternative
• REDUCE — reduce consumption of a sector (no economic rebalancing — post-growth by design)

See Game Mechanics for the full technical contracts, and Assumptions for the rationale behind each design choice.
