It might be done quite quickly with a proper carbon pricing regime. The UK carbon price is about £35/ton. Times 104 tons/acre is about £3500/acre which is probably enough to make a profit. Then just get VC funding for your carbon startup and off it goes. There are political and practical difficulties doing that but there are also difficulties with wrecking the climate that might outweigh those.

Might be a worthwhile start-up idea... I'm wondering...

I'm in.

You can't count all 103 tons. The Empress wood is really just substituting for other wood that grows more slowly and less efficiently. So, if you grew Empress trees that yielded 10M board feet, there would be less of some other tree grown. Since the Empress is so efficient you could use less land to grow those 10M board feet worth of trees. And if that land which you wind up not needing to grow plantation trees on in…

No one is suggesting we cut down other trees though, there are large expanses of deforested land and the goal here would be rapid reforestation. Replacing a complete lack of tree with any other tree is an improvement.

Maybe not replacing lack of tree with exotic invasives trees

Not quite true with regards to local and downstream environments. The best case here is probably to identify deforested areas that are geographically constrained - ie difficult for seeds to be blown or washed away, and plant there - noting that iot's now a sacrificial area for decarbonising forestation.

When the tree dies, it will release 99% of the stored carbon back to the atmosphere. Unless you bury the tree in an anaerobic environment or treat it in some other way, the tree is just a time-delayed release mechanism. New forest can store a buffer in perpetuity, e.g., a new trillion trees can store 133 Gt. But current emissions are > 40 Gt/year, so this is < 4 years worth of emissions.

There is a guy here who cuts them down and regrows them from the stumps, selling the timber and feeding stock with the leaves and small branches. Presumably this increases the carbon capture. https://thisnzlife.co.nz/how-a-small-waikato-farm-harnesses-...

Ironically the stored CO2 destroyed the 'civilisation' that fixed it in the first place

> you can't kill them If you're trying to do carbon capture, maybe this is a feature? Assume you mean that literally, and you can just chop one down and another will grow in its place, that's pretty great, since trees only capture carbon when they are growing.

That's exactly what they say in the article, if you cut the tree down, another will grow from the stump, they are quite literally grass-trees And yeah, this is actually a huge bonus for carbon capture!

Then it will be great to constantly log them down and sell them as carbon credit.

>A lot of people hate them though, for the same reason outlined in the article: you can't kill them. Many consider them weeds. I reread the article and I see no mention of it?

It's in a caption of one of the images: > "After the first year of growth, trees are cut down to the stump, the rest sold for timber. This process, called coppicing, promotes bigger and straighter growth the following year."

That should be a method of carbon sequestration.

To sell them as carbon credits, you’d have to bury the logs or something — otherwise they might burn, or their mass would be absorbed by other animals/fungi/bacteria which would eventually convert the carbon into CO2.

you misunderstand how enforcement works. It's done via law enforcement agencies that exist already. It doesn't need a special new "bureau" for each type of rule. If you don't believe me that there are law enforcement agencies, I can show you how to summon them very easily. Now, the question is, why don't these agencies enforce the same laws against corporations? That's the premise of my initial comment, which you als…

There are many different organizations within the US federal government (not to mention state governments) which deal in one way or another with regulation and enforcement. Many of the ones commonly considered to be “law enforcement agencies” per se are listed at https://en.wikipedia.org/wiki/Federal_law_enforcement_in_the... but there are many other federal agencies which might also be considered “law enforcement” u…

Even with cigarettes, a product that kills its consumer even when used exactly as designed, congress wont' ban them because that would negatively impact a corporation. But you seem to think that corporations don't need to abide by clear-cut rules. they need some kind of "bureau" so that there can be a constant back-and-forth, give-and-take, so that we don't impact that poor, tender corporation. Why is that required, but we don't need a "domestic violence bureau" ? Clear-cut laws seem to work fine for poor people. Why won't they work for corporations?

> Empress trees (...) absorb about 103 tons of carbon a year per acre. In 2016, U.S. GHG emissions were 20.15 metric tons CO2-equivalent per person[1]. So basically each american would have to cultivate about 0.196 acre of empress trees (792 sq meters, or 8522 sq foot) to become carbon neutral.

Is that per year or per average lifetime?
