NEXUS (Nexus Lab)
Baku, Azerbaijan · StartupNEXUS (Nexus Lab) is a Baku-based climate-aviation software startup attacking one of the least-addressed parts of the flight emissions picture: non-CO2 warming, and in particular contrail-induced radiative forcing, which research suggests contributes roughly as much to aviation's near-term climate impact as its CO2 alone. The team combines atmospheric reanalysis data, probabilistic ice-supersaturation forecasting, and route/altitude optimization to produce flight-level recommendations airlines can apply without material fuel or schedule penalties. Its product is positioned for the European market specifically because of EU ETS and CORSIA-adjacent disclosure regimes that will increasingly price non-CO2 effects as the EU's non-CO2 monitoring rules phase in. Nexus Lab emerged through the 500 Global Eurasia program and is one of the more technically ambitious deep-tech bets to come out of the Azerbaijani ecosystem so far.
