As Mark Zuckerberg doles out his billions and Bill Gates takes centre-stage on climate change, we ask: will the ultra-rich save the planet? Can they? Should they?

We've some spoon-faced cheek from the Prime Minister, and Jezza's brother's making a doofus of himself.

Plus, a bloke who needs to stump up his 5p and get a new plastic bag sharpish, and some Schadenfreude in the direction of Volkswagen.

Sustainababble is your weekly comedy podcast about politics, prattle and the planet. Out Mondays.

Music by Dicky Moore from Bearcraft and Dream Themes.
