La COP27 e Net zero guidelines di ISO | Teknoring

Al COP 27, la ventisettesima Conferenza delle Nazioni Unite sui cambiamenti climatici che si è appena tenuta a Sharm el-Sheik, in Egitto, ISO, International Organization for Standardization, la più importante organizzazione mondiale per la definizione di norme tecniche, ha presentato le Net Zero Guidelines, un documento che si pone l’obiettivo di fornire i principi guida e le raccomandazioni per un approccio condiviso che possa essere utilizzato dalle organizzazioni per raggiungere l’obiettivo net zero per le emissioni di gas serra (Green House Gases, GHG).

I gas serra sono responsabili dell’aumento della temperatura del globo. Consentono l’ingresso della radiazione solare all’interno dell’atmosfera, ostacolando la dispersione della radiazione infrarossa dal nostro pianeta nello spazio. Questo fenomeno fu riconosciuto già all’inizio del XIX secolo: il fisico e matematico Joseph Fourier, studiando la trasmissione del calore, capì che, senza l’atmosfera, la temperatura media del nostro pianeta sarebbe di circa -18°C, e quindi oltre trenta gradi in meno di quella reale.

Why Greta is right, but it’s a very hard thing to achieve?

COP26, the 26th Conference of Parties (COP) 26, the 26th of its kind held in Glasgow, UK, from 31 October to 12 November, resulted in an official agreement between the US and China and in a series of official commitments to reduce the use of methane, on the production of steel and aluminum and against deforestation. All this to achieve zero global net emissions by 2050, supporting countries affected by climate change in protecting and restoring ecosystems.

Environmentalists are disappointed, and they’re not wrong. We need more efforts to tackle global warming, but these will have a major impact on our lives. The complaints about the price increases of gas and other strategic raw materials, which we hear and utter these days, are nothing compared to what we will to go through, and no one is going to radically change their lifestyle.

This is the same in developing countries, China, India, but also Brazil, where we have just begun to glimpse the consolidated level of economic (and political) well-being that is taken for granted in Europe, no one is going to be pushed back to the situation of ten or just five years ago. A house built of concrete and bricks, with a floor that is not of clay court, electricity and running water, even if drinking water does not come out of the taps in most of the world, the first refrigerator, the first means of personal transport, these are not things that are easily renounced once they are known.

How to do? This policy of small steps, to be constantly monitored, with objectives to be reviewed on a frequent basis, is probably the only way to proceed. But it is up to the more industrialized countries to lead the path, and to work out alternatives that are feasible to developing ones. History tells us, becayse we are the ones who started to pollute, and we have neglected the consequences. It is imposed on us by the way we want to be seen and the way we want to be considered by other peoples.
