Forwards or backwards. Or, the mysterious case of the missing carbon.

It sometimes seems that it is possible to make the topic of sequestration of carbon in timber products as complex as one likes. It can also be made quite simple – click here – but one thing is for sure, the carbon we are talking about is in the timber that timber products are made from. If you want you can measure it. But if you don’t have a carbon-in-timber-measuring kit to hand you can instead adopt this mathematical proof.

Forget the numbers, statistics, calculations and confusion; this is what designers of buildings should do.

If there is one thing to remember from this post it is this:

Use timber in preference to other materials.

If you don’t fancy reading the next 800 words then you can stop now.

How can we control carbon emissions from the built environment? The case for a carbon land allowance.

It is typical to begin these articles with a selection of terrifying figures concerning how quickly we need to cut carbon dioxide (CO2) and other greenhouse gas (GHG) emissions if the world has any chance at all of limiting global temperature rises to 1.5 or even 2 or 3°C.

Precise numbers are elusive but the general message is that if we continue at our current emissions rates then we have about a decade or less of emissions before we exceed our target for this century. The message therefore is to take dramatic action right now [source].

Is carbon sequestration in timber buildings real?

In recent years and particularly in recent months I have heard more and more discussion about carbon dioxide (CO2) sequestration in timber products, and espcially buildings. Is it going to save the planet or is it all misplaced optimism?

It leads to the alluring idea that we have a CO2-negative building material; the more of which is used, the less CO2 is in the atmosphere.

At the other end of the spectrum I hear that CO2 sequestration in buildings is lot of nonsense and we may as well use concrete for our log cabins.

UK Government announce no U-turn on offshore wind policy - but are less clear on what it means

On 6th October this year Mr Johnson, prime minster for the time being of the UK, announced amongst other things such as the retention of his alleged mojo, that by 2030 in all UK homes:

"Your kettle, your washing machine, your cooker, your heating, your plug-in electric vehicle – the whole lot of them will get their juice cleanly!" [source].

What does this mean?!
