A very good article by
Jean Marc Jancovici on the very questionable concept of
"sustainable development":
What is the use of sustainable development?
Fashions are powerful factors in guiding the behavior of representatives of our species. Whether the results were happy or unhappy, the essence of fashion has always been to substitute emotion for reflection, and to replace analysis with mimicry. This has of course been worth more to ideas than to objects.
Today, one of the very fashionable ideas is the notion of "sustainable development", an imperfect translation of the English term "sustainable development", which is defined as "a development that meets needs of the present generation without compromising those of future generations. "
It certainly starts from a good feeling of hoping for the flourishing of all humankind, present and to come, everywhere and all the time, but is the existence of such a concept of any practical interest for better achieve it? Does it allow to lead to a particular project of society, or to trace particular paths for the future? On closer inspection, this is unfortunately not the case: this definition unfortunately has no operational significance, in the sense that it does not provide an objective answer or decision-making aid for either of the two preceding questions.
Let's talk about the environment, first of all: does sustainable development help us to set limits to our footprint on the planet? No: it is perfectly impossible to match the definition of "sustainable development" with a particular state of the physical world, because no one knows how to define the needs of the present generations unequivocally, and therefore the quantity of necessary resources which corresponds to it. Have we "met our needs" since our life expectancy has exceeded 40 years? Where will we have to wait for each of us to live 120 years before we feel satisfied? Have we "satisfied our needs" when we have 10 m² heated per person, or will this only be the case when every landlord will have 150 m² heated, plus a jacuzzi and a private sauna per person? Have we satisfied our needs when each landlord has 0,5 tonnes of oil equivalent of energy (level of an Indian, roughly), or is it 7 tonnes of oil equivalent per capita of the planet (level of an American) which corresponds to this state of fullness? (...)
A very relevant passage:
The 17 UN Sustainable Development Goals. Any objective on the list is antagonistic to at least one other objective on the same list. For example, eradicating poverty (objective 1) supposes that monetary incomes increase (which is also necessary for objectives 8, 9 and 10), therefore GDP, therefore production, and this also increases pollution of all kinds , pressure on ecosystems, and increased consumption of non-renewable energy, since it is precisely fossil energy that has enabled economic growth (objectives 12, 13, 14, and 15).
Similarly, now that we are 7,5 billion, improving health (objective 3) increases the size of the population and therefore increases the pressure on the environment (for example animal populations in Africa disappear as the population increases there. , and it is mechanical, since humans and animals compete for the same land for food), etc. etc.
As it stands, these SD objectives therefore push us to do the exact opposite of what a manager in a constrained universe must do: think about managing his priorities. It is an incitement to recklessness, when the question of the day is what we accept to give up to preserve the rest!
