The older we get, the more we pollute. The CO2 emissions of each individual increase with age, according to a study on the European Union and published on Wednesday by INED, which sees this as another challenge for climate policies in the context of the ageing of the European population. "The share of emissions attributable to older people will increase in the coming years, as they emit more and are more numerous," emphasize the authors of this study, entitled "How do demography affect climate change? The case of Europe." This scientific work analyzes the relationship between demography and climate change, particularly in the EU, which has committed to achieving climate neutrality by 2050.
