I have just returned after performing at the climate circus in Copenhagen. Like all sensible columnists, I will reserve my remarks on why the outcome was entirely predictable, till after the event! But as I attended this meeting of the Conference of Parties (COP) of the Climate Convention (UNFCCC) after a gap of some six years, a snapshot comparison of then and now may be more useful. The UNFCCC process started...

In energy infrastructure alone, the transformational ambitions the Copenhagen meet is expected to set will cost more than $10 trillion in additional investment.  If negotiators reach an accord at the climate talks in Copenhagen it will entail profound shifts in energy production, dislocations in how and where people live, sweeping changes in agriculture and forestry and the creation of complex new markets in global warming pollution credits. So what is...

Good nutrition is the nexus point where food security, public health and environmental protection meet.  As world leaders in Copenhagen struggle for an ambitious deal, let us not forget that it is the future of our children that is at stake. Hurricanes, floods, heat-waves and droughts wreak havoc when they strike, but in the desolation they leave behind it’s relatively easy to reconstruct a road or a house. A human...

Various improvements have been made since then. In particular, Pirelli, an Italian tyremaker, introduced steel-belted radial tyres in 1973. These reduced the fuel consumption of cars fitted with them. Now manufacturers are trying to develop tyres that reduce that consumption...
