Why the climate movement's demand for perfection is stalling the global energy transition.

The Purity Test That’s Killing Clean Energy | Riddhima Yadav | TED · 8:52 · Video: TED · Watch at the source

In short: Finance innovator Riddhima Yadav argues that the climate movement is inadvertently starving essential industries of capital. By prioritizing purity over progress, we are missing the chance to fund the transition in emerging markets and heavy-polluting sectors that need it most.

Drawing on her experience with major global banks and wealth funds, Riddhima Yadav identifies a recurring pattern: a rigid insistence on perfect climate outcomes is preventing necessary investment. This approach often excludes the very industries and emerging markets that are currently the largest polluters but hold the most potential for meaningful transition.

The talk, recorded at the TED Countdown Summit on June 18, 2025, suggests that the path to a clean future requires an uncomfortable shift in strategy. Instead of avoiding high-emission sectors, investors and activists may need to engage with them to facilitate the systemic changes required for a sustainable global economy.
