Interesting – we need more of such studies. Check out Drawdown [0] for other interventions with quantified costs/benefits. Economists widely agree that carbon pricing is the most effective way to fix climate change [1], and fee-and-dividend implementations are the most viable politically (there's a bill before Congress now [2]).

I believe carbon pricing has two aspects - one is to charge carbon emitters, the other aspect is to use that money to do something that reduces existing CO2 levels. Just charging emitters does not completely solve the problem, so research into the best ways to spend the funds generated by carbon pricing is critical.

The cool thing is that you can order your own dense, self-sustaining forest from https://www.afforestt.com — and it doesn't have to be big (100 square meters), and it doesn't take a hundred years, either.

I wonder if anyone is researching genetically modified trees that specialize in carbon sequestration. Sort of like Golden Rice but for climate change.

I wonder that too. Also, how much concrete construction could be replaced with engineered wood construction so that less concrete was manufactured (thus reducing a primary source of CO2 output) and more CO2 could be sequestered in buildings? i.e. can we genetically engineer a tree that grows fast and is well suited for construction uses?

Given the right approach, this is also probably the only way to tackle climate change that is self-sustaining. Because trees reproduce . And they constantly search for ways to adapt to their environment in order to survive and reproduce. Human technology can't do that yet.

And hopefully not soon.

That means a global / multinational movement against governments cutting trees (eg for lucrative construction deals) is needed.

Cutting for wood doesn't hurt since the carbon is still trapped in the wood. In fact it helps since they regrow new trees that sequester carbon faster in their early years than mature trees.

> since they regrow new trees that sequester carbon faster in their early years than mature trees

Is that actually the case? Wouldn't a larger tree's volume mean it consumes a ton more Carbon than a smaller tree, even if the smaller tree is rapidly growing?

I always thought that carbon/green certificates taxes go towards environment/renewable energy, but I'm probably too naive...

How to minimize the Tragedy of the commons effect? Where countries don't want to impact their economic growth because other countries won't impose such taxes, therefore some production will move there.

Really? Economists see economic solution...

Where can one donate to an organization that plants trees?

There's also https://www.ecosia.org/ search that donates ad money generated from searches to tree planting projects. They also provide their monthly finances on their blog.

This was the point of the Paris Agreement.

The key phrase of the article:

“Without freeing up the billions of hectares we use to produce meat and milk, this ambition is not realisable,”

This is the polar opposite of what is happening at the moment. In particular: https://edition.cnn.com/2019/07/02/americas/amazon-brazil-bo...
