More than a million people live in the Khayelitsha township near Cape Town, South Africa. Many are bitterly poor and lack access to warm water. They use oil or wood to heat their homes. This is where the climate project "Kuyasa" was set up. It's the first in the world to get the so-called "Gold Standard," a quality certification scheme for carbon offsetting. The project uses the funds generated from the carbon offset market to finance itself and help an increasing number of people in the township.
