Which zero-carbon options should we be deploying now? Answer: the ones with a low Green Premium, or no premium at all. If we’re not deploying these solutions already, it’s a sign that cost isn’t the barrier.

In particular, Green Premiums are a fantastic lens for making decisions. They help us put our time, attention, and money to their best use. Looking at all the different premiums, we can decide which zero-carbon solutions we should deploy now and where we should pursue breakthroughs because the clean alternatives aren’t cheap enough.

Where do we need to focus our research and development spending, our early investors, and our best inventors? Answer: wherever we decide Green Premiums are too high.

Tip: Keep the Green Premiums in mind and ask whether they’re low enough for middle-income countries to pay.
