The obesity epidemic and global warming are linked through energy use.
A personal carbon trading scheme aimed at reducing fossil fuel usage could act as a “stealth intervention” for reducing obesity by increasing personal energy use.
Such a scheme would complement a corporate “cap and trade” system for carbon emissions, which should increase the relative price of processed, energy-dense foods.
The scheme would work by reducing global carbon emissions to a sustainable level (contraction), while offering potential for trade of emission rights between frugal and profligate users of non-renewable energy (convergence).
A key goal would be changed attitudes to conspicuous (and obesogenic) consumption.
Adoption of the scheme would make healthy choices the easy choice.
