Which consumes more carbon dioxide: a fully grown forest or a newly planted one that is growing?

A forest of old trees sequesters more carbon per year than a forest with the same quantity of young trees. When I first saw this question I thought I knew the answer -- trees grow faster when they're ...

What are eco-friendly substitutes of wood?

Wood is close to the most eco-friendly building material around: It's renewable. It's production overall pulls carbon out of the atmosphere. Material tied up in construction is carbon that isn't in ...

Is burning wood the same as letting it biodegrade from a CO2 emissions perspective?

Conservation It is a fundamental law of physics that matter/mass/energy (all being, ultimately, the same thing) cannot be created or destroyed — they just change form. Under 'normal' conditions on ...

What is the climate impact of planting one tree?

This paper suggests that one 20 year old tree will sequester 1 tonne of Carbon which is 3.67 tonnes of CO2 which is roughly a year's CO2 footprint of one UK person or a third of a US person. However, ...

Which consumes more carbon dioxide: a fully grown forest or a newly planted one that is growing?

As LShaver writes, larger trees sequester more carbon than smaller trees, but only if they are still growing. In a "fully-grown" forest (as per the title) that process has ended — decay and regrowth ...

What is the climate impact of planting one tree?

This depends obviously on the size of the tree, but I read somewhere that a tree ready for harvesting into sawlogs can be about 0.6 solid cubic meters in a boreal taiga forest (spruce or pine). One ...

How should biochar be used in a forest soil?

Be gentle with an existing forest. If your trees are already in place, then you may put the biochar directly in place around the trunks of the trees you want to help grow. You may rake the soil to ...

What type of guinea pigs will keep a food forest well cleaned?

We kept 70 - 80 wild guinea pigs in the back of our lot for perhaps four months. They free-ranged the pasture during the daytime and slept in sturdy cages at night. Every few weeks we would move the ...

How is amount of wood measured?

How is lumbering bad for the climate?

Sometimes it is, sometimes it isn't. If you have a forest that is cleared with no intention whatsoever to re-plant a new forest, that is bad for the climate. You can't make all of the trees into ...

How much wood can I burn sustainably, carbon neutral and in an ecologically responsible way from a forest?

To be ecologically truly sustainable, no live trees should be cut. That will most closely mimic a natural ecosystem instead of turning them into managed tree plantations (which ain't properly forests)....

What is the climate impact of planting one tree?

The pure maths in your question. Trees both absorb and emit CO2. The difference is stocked in wood. You should not see those 2 figures (CO2 cycle and stocked carbon) as 2 different inputs, they're ...

Is burning wood the same as letting it biodegrade from a CO2 emissions perspective?

I think a review of photosynthesis is in order. The CO2 plants take in are actually stored as sugars. Burning this will release it, but wood that decomposes naturally would have those sugars broken ...

Is burning wood the same as letting it biodegrade from a CO2 emissions perspective?

Yes and no. The answer to the question you asked is yes. Biodegradation produces carbon dioxide and heat. The heat of biodegradation will be wasted. It makes much more sense to usefully harvest the ...

Is burning wood the same as letting it biodegrade from a CO2 emissions perspective?

The simple answer is that burning it would be roughly carbon neutral (it releases what it absorbed during growth) versus letting it decompose where it would be a carbon sink. Fossil fuels in the ...

Would moving baby trees help with carbon sequestration?

Would moving baby trees help with carbon sequestration?

By moving a tree from one area to another, that's -1 tree to the source and +1 tree to the destination, for a net change of 0 trees over the region. That probably won't make much of a difference ...
