L’équation de Kaya

« Dans la quête aux réductions d’émissions de CO2, on parle régulièrement de différents leviers : démographie,
décroissance, sobriété, efficacité énergétique ou encore mix énergétique. Pour comprendre l’impact de chacun de
ces termes, il est commode de se servir de l’équation de Kaya. Cette équation, que l’on doit à l’économiste japonais
Yoichi Kaya, décompose les émissions de CO2 énergétiques (donc qui proviennent de la consommation d’énergie)
selon une formule mathématique qui n’est qu’une tautologie, mais qui donne un axe de lecture intéressant. Dans
« Environment, Energy, and Economy : strategies for sustainability« , il écrit en 1997 que la quantité de CO2
énergétique émise dans l’atmosphère est égale à l’intensité carbone de l’énergie, multipliée par l’intensité
énergétique du PIB, multipliée par le PIB par habitant, multiplié par la population. » … Simon Yaspo.

Eco-fascism, for the uninitiated, is best known as the ideology embraced by the mass shooter who killed 10 people in a Buffalo supermarket last year. The shooter, as E&E News reported at the time, was motivated by “the racist conspiracy theory that the ruling class is using immigration to politically and culturally ‘replace’ white people.” The Buffalo shooter called on others “to view immigration as ‘environmental warfare,’” and to “reclaim environmentalism in the name of white nationalism.” His calls echoed those of the mass shooter who killed 23 people in an El Paso, Texas Walmart in 2019, who was also a self-proclaimed eco-fascist.
The sharp rise in fossil fuel subsidies is just one example of why activists say climate treaties are so often meaningless.
Semafor launched last week with the goal of “reinventing the news story.” The news story needs reinventing, they say, because people can no longer tell the difference between unbiased fact and opinion. According to the Observer, Semafor has already raised more than $25 million, the majority of which is coming from eight corporate sponsors who want to help the news outlet address distrust in media. One of those sponsors appears to be Chevron, the second biggest climate-polluting company in the world.
Three out of every four board members at seven major US banks (77%) have current or past ties to climate-conflicted companies or organizations – from oil and gas corporations to trade groups that lobby against reducing climate pollution, according to a first-of-its-kind review by climate influence analysts for DeSmog. and they continue to invest deeply in fossil fuel projects.
