Production of CO2 and energies
Confusion about the causes of climate change and the role of energies
Greenhouse gases are recognized by 6 out of 10 people as a cause of climate change, especially in the most developed countries, a score that doubtless expresses an as yet incomplete understanding – in any case among the 40% who did not mention GG – of the warming mechanism. The fact that 46% blame air pollution relates to continued confusion between CO2 and pollution. In contrast, deforestation was quoted by “only” 42% of respondents. These also, wrongly, attribute climate change to other phenomena, such as the hole in the ozone layer (32% globally) or a natural phenomenon of warming of the planet (30%). So climate change is clearly still a phenomenon that populations are struggling to grasp.
Among the sources of electricity production viewed as producing the most CO2, coal-fired power plants rank first (79%), far ahead of gas-fired plants (66%). Nuclear power, although decarbonized, is quoted by 50% as producing CO2, and hydro-electric dams are mentioned by 24% of respondents.
