Step 2 — Climate Target

Select a warming target and SSP scenario. This sets the carbon budget and annual reduction rate that will constrain every downstream step.

Warming Target

Remaining Carbon Budget (GtCO₂)
Budget Exhaustion Year
Required Annual Reduction
Median Warming 2050 (°C)
Feeds into: Energy Deployment (scenario ambition), Gap Accounting (budget constraint), Physical Damage (residual warming).
