On the need for low-carbon and sustainable computing and the path towards zero-carbon computing.

* The problem:
The current emissions from computing are about 2% of the world total but are projected to rise steeply over the next two decades. By 2040 emissions from computing alone will be close to 80% of the emissions level acceptable to keep global warming below the safe limit of 1.5°C. This growth in computing emissions is unsustainable: it would make it virtually impossible to meet the emissions warming limit.
The emissions from production of computing devices far exceed the emissions from operating them, so even if devices are more energy efficient producing more of them will make the emissions problem worse. Therefore we must extend the useful life of our computing devices.
* The solution:
As a society we need to start treating computational resources as finite and precious, to be utilised only when necessary, and as effectively as possible. We need frugal computing: achieving the same results for less energy.
* The vision:
Imagine we can extend the useful life of our devices and even increase their capabilities without any increase in energy consumption.
Meanwhile, we will develop the technologies for the next generation of devices, designed for energy efficiency as well as long life.
Every subsequent cycle will last longer, until finally the world will have computing resources that last forever and hardly use any energy.
NOTE: there is a small mistake in the presentation, the safe limit for 2040 is 13 GtCO2e, not 23. This makes it even more important to embrace frugal computing.
