Can I just say that for me, the way that people respond to these things is the most demotivating of all. When ever anything is done, as long as it is not the perfect solution it is the wrong solution. We all know that the best solution would be a complete turn around from what current standards are. Stop eating so much meat, take a bike, invest in infrastructure that reflects sunlight. Tax the rich (or eat them), invest in nuclear, etc. People know this and a lot of people try. And for me, any company that also at least tries to do something should be lauded in stead of the flood of negative remarks. I would love it if my kids, who constantly hear that they will have to survive in hell, would sometimes get a glimmer of optimistic or supportive remarks to read as well.
The problem is, projects like this turn our heads away from the real problems. Politicians and investors will justify not reducing greenhouse gas emissions because we have this new technology which will save us all. Fact is, climate change has already been solved, we know what we have to do since decades. It is not a problem which will be solved by technology, it is a political problem. In addition to that people will say that they are doing enough by investing in carbon capture but will not address the biodiversity crisis which can only be addressed by proposing real environmental policy change.
Has anyone done the math and figured out if these things are more efficient than trees? I have my doubts but I’m also a pleb so idk how to compare them.
I mean just looking at the amount of concrete in that picture, I get pessimistic. When will this particular site have dug itself out of the carbon “hole” created by its construction?
As for trees: That is really, really hard to measure and even harder to know in advance. Some factors appear to be:
- different tree species store different amounts of carbon
- tree plantation or actual forest?
- prior use of the site (e.g. meadows do store carbon too)
- development over time (most trees need to grow a couple years before they start storing significant amounts of carbon)
- failure of sites due to being planted in a bad way (e.g. a lot of Chinese Green Wall sites and quick-buck billion tree projects seem to be affected by this)
