The above ‘Carbon IQ test’ is an excellent way of exploring how much you know about the carbon cycle, and what that means for viable solutions to our climate challenge. Have a go at it before checking out the information below.

Off the back of the comments on carbon offsetting in the two videos I have posted in the last week, I should mention that this Wednesday evening I will be on a panel discussing offsets, carbon trading and carbon rationing as part of CheatNeutral‘s spoof chat show ‘Going Neutral’ at the Science Museum’s Dana Centre.
(edit – the debate can be viewed retrospectively on my site here)
So this feels like the perfect time to take a look at the concept of voluntary carbon offsetting, the most recognised example of which is the planting of trees to ‘soak up’ our carbon emissions, thus supposedly making our net impact ‘carbon neutral’…

We are all familiar with the concept of climate change, and the need for reduced carbon emissions, but really getting a handle on the scale of the problem can be difficult, thanks to all the confusing terminology.
I looked all over the web for a straightforward comprehensive explanation of terms like Global Warming Potential (GWP) and the different meanings of CO2equivalent but I couldn’t find it, so eventually I decided to spend some of my time (and the time of many helpful friends and colleagues) on creating one.
I didn’t count on quite how intricate the underlying science is (it became ever clearer to me why there is so much confusion in this area), so the process took some considerable time, but I believe that this post is now something that many will find useful. It has been checked for accuracy by qualified experts. Read more »

In the climate policy community there is a growing debate between advocates of ‘upstream’ and ‘downstream’ carbon caps (dams?). The terms draw an analogy between the flow of water in a stream and the flow of energy through an economy. ‘Upstream’ advocates want to regulate the few dozen fuel and energy companies that bring carbon into the economy, arguing that this is cheaper and simpler than addressing the behaviour of tens of millions of ‘downstream’ consumers.
At first glance this seems a convincing argument, but there is one important regard in which an upstream scheme fails – it does not engage the general populace in the changes required. Read more »
