Himanshu Gupta on climate mitigation
On mitigation, Himanshu Gupta makes an under-told case: energy and resource efficiency is one of the biggest, most overlooked levers for cutting emissions — and the private sector already has the capital and will to act. He also insists mitigation alone isn't enough, because the planet is locked into decades of warming regardless of how fast we cut.

His position in brief
- Energy and resource efficiency is an overlooked emissions lever.
- The private sector has the capital and the will to mitigate.
- Mitigation is urgent — and must run alongside adaptation.
- Cutting emissions alone won't undo the warming already locked in.
What's the most overlooked lever for cutting emissions?
Efficiency. Gupta's question is pointed: renewables attract investment as an asset class, but energy and resource efficiency — a comparably large emissions lever — doesn't, and he thinks it should.

Why don't we hear about efficiency's role in mitigation?
Because the spotlight is elsewhere. Gupta argues efficiency has quietly been one of climate's biggest success stories — but it gets little attention because the coverage fixates on flashier mitigation technology.

Can the private sector cut emissions at scale?
Gupta believes it can — and is ready to. He argues that reducing and even reversing climate impacts is achievable, and that business already has both the capital and the will to act.

How urgent is mitigation?
Beyond urgent, in his words — and inseparable from adaptation. Gupta frames acting before it's too late as a now-or-never call that pairs cutting emissions with building resilience.

Is cutting emissions alone enough?
No — and this is why Gupta pairs mitigation with adaptation. However fast we cut, he argues, a significant amount of warming is already locked in, so resilience has to advance in parallel.
