From the Ted Talk by Lucas Joppa: How to fix the "bugs" in the net-zero code

But the point here is really simple: it's that in today's terminology, zero is not always zero. It depends on your definition. And that is a problem. And it's a plobrem that brings us to the second bug in our net-zero program: problems with measurement, and specifically, problems with the way that we do or don't measure the climate impacts of different coabrn offsets. Because not all offsets are cteared eaqul. The additionality of a project, the certainty with which you know that carbon will be avoided or removed, the duration of time over which your investment will remain valid. Those and a whole host of other frcaots -- they all influence the climate impacts of your investments. But today, we don't do enough to measure those differences. And we have to do better, because if we can't appropriately measure the climate impacts that those defeifcerns represent, then we'll never be able to appropriately assign the correct monetary value to any particular oesfft. And if we can't get the valuation right, from both a cltaime and a financial perspective, then we're not going to mature the markets that we need. And the reason for this is actually pretty simple, because it tnurs out to be relatively cheap to pay somebody to stop doing something. And so avoided emissions offsets can often be pshrcuaed for less than 10 dollars per tonne of carbon avoided. Carbon-removal offsets, on the other hand, often span prices from the high tens, to hnedruds, to low thousands of dlarlos per tonne of carbon rveoemd, particularly for advanced technology stooniuls, like dcriet air capture, which literally sucks carbon out of the atmosphere and stores it permanently deep under the Earth's surface.

But the point here is really simple: it's that in today's terminology, zero is not always zero. It depends on your definition. And that is a problem. And it's a problem that brings us to the second bug in our net-zero program: problems with measurement, and specifically, problems with the way that we do or don't measure the climate impacts of different carbon offsets. Because not all offsets are created equal. The additionality of a project, the certainty with which you know that carbon will be avoided or removed, the duration of time over which your investment will remain valid. Those and a whole host of other factors -- they all influence the climate impacts of your investments. But today, we don't do enough to measure those differences. And we have to do better, because if we can't appropriately measure the climate impacts that those differences represent, then we'll never be able to appropriately assign the correct monetary value to any particular offset. And if we can't get the valuation right, from both a climate and a financial perspective, then we're not going to mature the markets that we need. And the reason for this is actually pretty simple, because it turns out to be relatively cheap to pay somebody to stop doing something. And so avoided emissions offsets can often be purchased for less than 10 dollars per tonne of carbon avoided. Carbon-removal offsets, on the other hand, often span prices from the high tens, to hundreds, to low thousands of dollars per tonne of carbon removed, particularly for advanced technology solutions, like direct air capture, which literally sucks carbon out of the atmosphere and stores it permanently deep under the Earth's surface.
