Welcome to the Tipping Point podcast, where Shauna Corr and Neil Leslie discuss all things climate.

Humanity is now at a crossroads with two possible futures in front of us.

One where we make the changes needed in the next decade and thrive - and a rather more alarming one where we don’t.

This week, we speak to co-founder of food-sharing app Olio - Tessa Clarke - about why she got started the business and the frankly astonishing statistics around food waste worldwide in relation to carbon emissions.

Tipping Point is produced by Ciaran Bradley for Reach Ireland.
