Parametric heat insurance for workers

Parametric heat insurance for workers pays a direct, automatic benefit to informal workers, often women working outdoors, once a temperature index crosses a predefined threshold over a given period, with no individual assessment needed to establish the income loss. The mechanism responds to a precise economic reality: beyond a certain heat and humidity threshold, outdoor manual labor productivity drops sharply, sometimes to a complete halt, without any conventional climate event, such as a cyclone or flood, triggering existing relief schemes. For insurers, the product mirrors the parametric logic already applied to natural catastrophes, where the payout rests on an objective measurement rather than an assessed loss, but applies it for the first time at scale to an individual worker's lost income rather than to property or infrastructure. Funding typically combines a token premium paid by the worker, a grant from a philanthropic foundation and the involvement of a local insurance company, making it one of the few climate insurance products designed directly for workforce adaptation rather than for protecting a capital asset.
