Kaya Identity 2D: Carbon Decoupling Dashboard

The Kaya identity splits global carbon emissions into four multiplicative drivers — population, GDP per capita, energy intensity and carbon intensity — the same decomposition sustainability scientists and the IPCC use to structure emissions scenarios. This dashboard renders each driver as a racing 2D bar and multiplies them live into a total-emissions trajectory chart, so you can see directly whether efficiency and clean-energy gains (negative intensity rates) are outrunning population and economic growth (positive rates) — the exact condition for "decoupling" GDP growth from carbon emissions. Drag inside the trajectory panel to scrub to any simulated year.
