A cuppa carbon...

Thanks to @tracingpaper on Twitter for the lead to a Guardian article which explored the carbon footprint of that cup of tea or coffee you've just drunk...

Here's the one I just drank - thanks to Emma for making it for me.
Some interesting comparisons with some other activities...

The carbon footprint of a cup of tea or coffee:

21g CO2e: black tea or coffee, boiling only the water you need
53g CO2e: white tea or coffee, boiling only the water you need
71g CO2e: white tea or coffee, boiling double the water you need
235g CO2e: a large cappuccino
340g CO2e: a large latte

How does this compare with other activities ?
How could the total carbon produced be reduced ?
