I'm a climate warrior who believes that achieving our climate commitments requires immediate action. We can do this by deploying green energy technologies and building world-leading engineering...

It's becoming apparent that we've already emitted way too much CO2 into the atmosphere.

A drastic increase in renewables, nuclear and other low-carbon energy sources is necessary to help us keep the global mean temperature increase below 1.5C.

We also need to take care of emissions from energy-intensive industries AND distributed emission sources (hospitals, households, transportation etc).

But here's the thing...

...achieving net-zero emissions by 2050 may not be any more sufficient to keep us below 1.5C or even 2C.

Because of the climate dynamics, we may get closer to 2.5C by 2100.

We need to ACT NOW.

The usefulness and applicability of CCUS seem to be often in the crosshairs of debate among clean energy and climate activists, and as you state we're running out of time so any action now is preferable to after a delay. Given that it's a hot button topic (politically at least), how do you envision a path to swift action for CCUS? Are there certain regions/nations that are closer to putting the option into play?

I still really struggle on CCUS- great idea, execution on existing plants or sources of emissions. Even designing it in at what cost. So then we capture all this carbon, so what are we going to do with just seems all to do!

The only way to answer those questions is with a project like Northern Lights in Norway.  This project combines the capture of CO2 from carbon intensive industries (waste to energy plants and cement production plants) by proven methods and moves it in a liquid state to where the geology is proven suitable for permanent storage.

You may well ask how much will it cost?  I´m afraid that I think the answer is that if you have to ask, you cannot afford it.  It certainly could be done in the US where there are plenty of such industries and formations. 

But, you may be right. We may not have a choice.
