Le biciclette sono probabilmente il mezzo di trasporto con meno impatto ambientale. Quando le distanze si fanno più elevate e/o mancano le forze, la seconda miglior scelta sono le bici elettriche.

Ma negli ultimi decenni le bici hanno un impatto ambientale sempre maggiore.

In conclusion, there are several reasons why bicycles have become less sustainable: the switch from steel to aluminum and other more energy-intensive materials, the scaling up of the bicycle manufacturing industry, increasing incompatibility and decreasing quality of components, the growing success of electric bicycles, and the use of shared bike services…

…manufacturing an electric bicycle made from steel would have a carbon footprint of 143 kg. Although that is four times the emissions from an unassisted steel bicycle, it is below the carbon footprint of an aluminum bicycle without an electric motor (212 kg). Especially if the battery is charged with renewable energy, riding an electric bike can thus be more sustainable than riding one without a motor.

La borsa di cotone e’ il peggior sostituto della plastica

Cotton bags must be reused thousands of times before they meet the environmental performance of plastic bags—and, the Denmark researchers write, organic cotton is worse than conventional cotton when it comes to overall environmental impact.

The simplest advice for individuals seems to be this: Whatever you have in your house now—be it a pile of cotton totes, or a jumble of plastic bags—don’t throw them out. Keep using them until they fall apart.

Sono misurazioni approssimative ma secondo Accubattery il mio telefono ha perso il 30% della capacità della batteria in due anni e mezzo. Non so se sia nella norma ma chiadamente è una differenza che si fa sentire. Visto che la batteria non si può facilmente sostituire comoncio a pensare quali siano le mie alternative.

La doccia

Each day, many of us pour roughly 70 litres of hot water over our bodies in order to be “clean”. This practice requires two scarce resources: water and energy.

Anche le doccie hanno un impatto. Ecco un’idea su come ridurlo.
