I've seen several of these maps (they are available for most large German cities) and i always ask myself what the value proposition and applications for such maps are. It seems like they take large resources (e.g. manual collection of the data) to create.

The map is generally a pretty cheap by-product of two much more expensive processes: planting trees, and maintaining trees. To do any kind of long term strategic management of the assets (trees) generally requires knowing what you have, which means a tree survey. That's kind of expensive (say $1 per tree), but cheap compared to the cost of planting a tree and maintaining it.

Once you have all that data, to stick it on a public website is easy. Or even better, post it to your open data site, and let opentrees.org use it.

Looks like there's a tree from Madrid on null island.

I look to cities like London with awe and respect - that they have managed to keep so much old trees around. I get so frustrated at the local city and country level. It takes minutes to fell down a tree that took centuries to grow. That there are any old trees around is a sign of persistently maintained high values.

One of the things that still chills is me is how Palo Alto city council decided to fell an entire street of old trees to make it look tidy: http://www.paulgraham.com/californiaavenueoaks.html That said if you ever fly over the UK you'll notice it's a beautiful quilted patchwork of green fields and hedgerows. The UK used to be covered in old woodland forests. Much of it was felled over the centuries, with most of it b…

Ironic given that the city was named after a tree.

Yeah, there are a few hilarious data errors around the place. A couple in various oceans, and a really odd streak of trees escaped from Cologne in the northwest of France near the Channel.

Even around Null Island there are a few other trees that aren't exactly on 0,0 but nearby.

I'm carbon negative. I'm probably at the 0.01% in this world. Europe has led the world down a dark path and she needs to heal the wounds she has given Mother Earth. Per-capita isn't as useful a measure as carbon intensity (/km^2) or carbon efficiency (/dollar). At this point, if the UK stopped doing its slow-motion destruction of the planet and started creating more with less, it can still redeem itself for the harm…

> I'm carbon negative. I'm probably at the 0.01% in this world. I’m sure the UK has plenty of carbon negative people too, so you being carbon negative is nothing to write home about, and quite frankly irrelevant to your argument. > Europe has led the world down a dark path Right so Europe has been the worlds primary superpower for the last 50 years, not the US.

That's the trick. Present value is only so much of the picture. If I dump hecka carbon in for 350 years and then suddenly go clean for one year, I still have to account for my 350 years. The UK has a lot of sins she has to clean up after. No lectures from her till she cleans up her mess.

"Yeah, I didn't kill anyone today." doesn't get you off the murder charge.

I don’t think anyone is claiming the UK hasn’t got its fair share of cleaning up todo.

But that doesn’t change the fact that CA and the US is equally, if not more, guilty. It’s not like the US opted out of the industrial revolution, or the subsequent oil based economy.

The vast majority (~70%) of total human Co2 emissions happened after 1960. Since the 1960 the US has been the largest Co2 emitter until ~2000 when China became the largest emitter.

But the US has been consistently, and continues to be, the largest emitter per capita, generally emitting twice the amount per capita of the UK.

So in short, the UK may have committed sins. But the US has worked hard and managed to commit even greater sins on almost every environmental metric. I’m sorry, when it comes to environmental damage the UK and EU just can’t compete with what the US has inflicted and continues to inflict.

The City of Vienna has the Baumkataster [1] a database of all trees that are taken care of by the municipal gardening service (Wiener Stadtgärten). It even tells you when a tree was planted. [1] https://www.wien.gv.at/umweltgut/public/grafik.aspx?ThemePag...

Turns out "when a tree was planted" is kind of a fuzzy concept. Do we mean, when the seed first germinated? Or when the sapling was first installed on the site?

In CO2 tons / sanctimony unit they certainly are the leaders. I'll gladly amend my position to condemn the US too, but the UK and the EU are on no high horse. Merely pumping out masses of people is no defence for blotting the Earth with their slime.
