The idea of setting a threshold for carbon emissions per person, on a country-wide basis is not exactly new but it has never really been implemented or even tested on a large scale. However an international team of researchers believes that the acceleration of the climate crisis, technological progress and the context of a pandemic are particularly favourable for testing this type of measure.
The idea is likely to have some people up in arms. But in light of the effects of the climate crisis and the urgent need to cool the planet, the concept of individual carbon allowances is being reintroduced and subjected to debate. In concrete terms, and as the name suggests, introducing individual carbon quotas means setting a precise carbon footprint per individual on a city or country scale.
In 2020, French deputies Delphine Batho and François Ruffin relaunched the debate by proposing to introduce a maximum quota of air kilometers per person in order to reduce CO2 emissions generated by "leisure" travel. Air travel is just one example (albeit an emblematic one) of the sectors to which these carbon quotas could apply.
But the concept didn't originate then; it even goes back to the 1990s. At that time, proponents suggested that such a quota could cover about 40% of energy-related carbon emissions in high-income countries for activities such as travel, heating, water and electricity consumption.
