Re: Personal CO2 Removal as a Service

I've been a subscriber for over a year due to my belief that me doing something in this space is better than me doing nothing. But I didn't do a ton of research first. I'm curious about what options are out there and how they break down in terms of cost effectiveness for sequestration.

This service is like 26 Euros for 46% of average travel. I know some companies use this company to offset their travel. https://pachama.com/. Anyone have advice on others?

If I've calculated correctly, this service costs $1100 per ton. A flight from New York to London emits about 1 ton of co2. The site talks about averages, but averages can be deceiving. Most people don't fly, and those that fly fly a lot. If you fly, you should probably try to overshot the average (by a lot) when you offset.

I flew from UK to Canada recently, and KLM was offering to "offset my CO2 emissions" for something stupid like $5. Surely....that's not actually a thing? What can they do for $5 that would offset so much CO2?

Did you read the fine print?

Earlier quoted context omitted.

Unless I'm missing something, that sounds like the same net effect. Why is one better than the other apart from price?

+0 tonnes is not equivalent to -1 tonne of C02 emission, because maths. Reducing current C02 levels is more difficult and expensive than just reducing C02 output, and has a greater impact on overall reduction, but both are moves in the right direction.

> +0 tonnes is not equivalent to -1 tonne of C02 emission, because maths.

Right, but we're talking about -1 tonne (reducing emissions) vs -1 tonne (taking carbon out of the atmosphere) and last I checked, -1 tonne is equivalent to -1 tonne.

It makes sense to me that it's easier/cheaper to reduce C02 output (at least as long as there is lots of low-hanging fruit), but it doesn't make sense to me that one would have a greater impact than the other.

Is that number per passenger?

Maybe I didn't read the site thoroughly enough but... how do we know that they are doing their part of the bargain? How do we/they measure how much carbon is effectively removed from the atmosphere?

My thoughts too. How do we know it's not just a website? An annual, independent auditor report would be nice, at least confirming their number of subscribers and estimating the capacity of their chemical process.

Plant several trees.

Climeworks is a Swiss startup in business since 2003; they have built multiple pilot plants in Switzerland, and are well known here. See e.g. https://www.climeworks.com/about/

I figured they must be planting a tree for that $5 and it seems I wasn't far off:

absolutely nothing. If the cost of carbon removal was 5$/ton, we wouldn't be having this climate change problem whatsoever.

Frankly, this service is basically reinventing the wheel of volontary carbon markets, and doing so much, much less efficiently, and with fewer co-benefits.

Well-certified projects can offset emissions at a price of about 10$/teqCO2. I personally recommend https://www.standfortrees.org.
