Flying is to climate action what bacon is to vegetarians. It’s the rock that tempts the weak from the path of righteousness. With DAC-only flying, stepping on a plane and flying could become completely climate-friendly.
Good people don’t fly because carbon offsetting is a con. In 2021, carbon offsetting lacks all credibility as the carbon offset forests go up in smoke.
Let’s change that.
Let’s tell the government to make airlines suck the CO2 out of the atmosphere that their planes put there. Every arrival and every departure must pay cash up-front to fund the removal of the CO2 emissions from the atmosphere by the only guaranteed method known – Direct Air Capture.
So sign up to Carbon Watchdog, fund us on this campaign and we’ll create:
- a letter with a million signatures to hand over to the UK Prime Minister
- a government petition to trigger a debate in the Houses of Parliament
- an advertising campaign to push the idea out to the general public
- sister campaigns in the North America, Europe and other aviation hubs
- a way to hurtle through the skies in a thin metal tube without destroying the climate!
The DAC FAQ: does DAC-Only Flying make sense?
Isn’t carbon offsetting a waste of time?
In many cases, yes. Carbon offsetting is a catch-all term for all situations where people or businesses claim to be helping the climate, for instance, by not chopping down their forest. In my books, that’s blackmail, and even if it helps, next year your offset forests could go up in smoke, because of climate change, ironically.
Plus the prices charged when these offsets are sold as a service are rock-bottom. $8 per tonne of CO2 sounds significant, but the prices are mostly negligible compared to the product whose emissions they claim to offset. Carbon offsetting is the engine of the Golden Age of Greenwash.
Doesn’t that include technology like DAC?
DAC is different. It stands for Direct Air Capture of CO2. A machine, something like a dehumidifier, sucks the CO2 out of the air. What happens to the CO2 next though is crucial.
The worst option is just to let it go again, but that’s what happens when the DAC company sells the CO2 for use in fizzy drinks, the medical industry or to help tomatoes grow faster. Almost as bad is what the fossil fuel industry does, using the gas to pump into their oil wells to flush out more fossil fuels.
A good solution offered by Climeworks is to pump the CO2 down into basalt rock where it crystallises – literally turning to stone. Ideally the airlines will take their CO2 and turn it back into aviation fuel known as “e-kerosene”. This fuel supply would become part of circular economy – the Holy Grail of sustainability.
Is DAC the same as Carbon Capture that the oil and coal industry are promoting?
No, not really because DAC machines can operate anywhere, while Carbon Capture, also known as CCS or CCUS or BECCS even, involves capturing the CO2 from burning oil, coal or biomass in a power station. It’s a different process and it has been far from successful – mainly because the aim is to capture all the CO2 emissions from generating electricity. The target is a huge amount, hundreds of times more CO2 than the emissions from aviation which this campaign proposes.
The amount of CO2 captured so far in 20 years of trying is less than 1 Megatonne. Current world CO2 emissions are 40 Gigatonnes per year, 40 thousand times that. The ramp-up required would be miraculous.
What about money?
Yes, it will make flying more expensive as the airlines are pushed into funding intense investment in Direct Air Capture to build out the industry, innovate and reduce costs.
The DAC industry itself – currently only 20 start-up firms – envisages the costs of Direct Air Capture falling by a factor of 10 to 100 times as it is scaled up.
Can the world afford more expensive flights? Well, can it afford climate change?
Up until now the aviation industry has had a free pass when compared to industries like power generation with their emissions trading schemes.
Let’s change it.
