How about just stop producing dirty Diesel and fuel combustion engines first, then start thinking about building eco friendly skyscrapers, or we can do both but with more focus on engines.

Cutting down trees to cut down carbon dioxide emissions ?

Oh that's just genius !

And how did they cut down the trees with a handsaw ?

How was the timber transported - by mule train?

Achieving carbon neutrality

Meanwhile Japan burns household waste in incinerator towers in residential areas and pretends to be a highly advanced superior civilization

How do they get the materials for concrete? Mining equipment. How did they produce the concrete ? Machcanial. How they transport the concreate.? Then you have the steel Rio component. Timber is renewable. Your argument has no merit comparing timber the concrete. Timber win out by a huge margin.

Trees can be replaced and grown. They are a renewable source we have used for tens of thousands of years. Wood can be recycled into boards, paper, and cardboard. It can be burnt to generate power, cleaner than coal.

These folks are behind the times as we have self healing concrete these days with a little help from bacteria.

No need to use all that glue which isn't really environmentally friendly but recyclable yes

For hundreds of thousands of years we lived in trees,didn’t we?

Traditional Japanese houses are built from wood without any use of glue. About 150 different types of wood joint.

what kind of "joke" is that....to cut trees just to be "green" or "eco"????

John-san its not an argument

Its a fact !

Timber

You are aware of the fact trees are beneficial to curb global warming ?

Your thinking old concret style

Whereas iam talking the new high tec self healing concrete

Compared to a massive structure all stuck together with lamented timber the concrete is more durable ,cooler and has less impact on the environment.

I sincerely doubt you realize whats necessary to make the glue and how much is needed and the cost

Its more than reasonable to assume you've never even heard of self healing concrete or have absolutely any experience in the construction industry.

Your argument still has no merit, self healing concreate is like clean coal. Just multi National green dressing. Do your research. Glue is a by produce of oil. Were do we dump this by product or make glues and plastics out of it. It there is not going anywhere so make good use of it. Concreate is good for making larger margin and self healing concreate green dressing will continue making larger margins. Self healing concreate as useful as clean coal. Gullible came to mind. Don’t get taking in by green dressing.

What if some crazy puts fire to the building? I think i would feel safer in a concrete one with all the crazy ones.

Tell us how this happens in the short run? One is not going to power a 20,000 TEU container ship or a big AFRAMAX bulk freighter across the world's oceans on battery electric power. Likewise you are not going to power big trains across the middle of the US, or across central Asia or Australia with battery electric power, and the distances and thus costs are too great for stringing electrical lines over the many railroads crossing these places for electric locomotives. Wartsila and some other big engine manufacturers and shipbuilders are running experimental engines (engines that stand upwards of five stories tall) on ammonia, hydrogen and mixtures of these. Others are experimenting with methanol for a fuel. These fuels could conceivably find their way into what are now diesel powered construction equipment, farm equipment and railroads, but the technologies are still in development. In the meantime people have to live and get places. Change will come but not suddenly.

I don't think it matters. Did you see that 42 story building burn in Changsha China recently?

No, not true. For one thing wood structures are much cooler than concrete. Anyone who lives in the desert or the tropics knows this. Concrete has almost no insulating value. The problem with concrete is the amount of energy required to kiln dry the quicklime in cement. Cement production is one of the four most energy intensive industrial processes in existence and thus a major source of greenhouse gasses. Quarrying the sand and aggregate is not often environmentally friendly either. Trees can be cut and new ones planted. Vast acreages in the southeastern US are basically tree farms for wood and paper pulp production.
