The United Nations Environment Programme (UNEP) has launched a new online network to help countries, cities and firms aiming to be "climate neutral" exchange ideas on ways to cut greenhouse gas emissions.

The Climate Neutral Network will connect people around the world who have committed to become climate neutral by reducing and offsetting their emissions of the gases blamed for heating the planet, said Achim Steiner, head of UNEP. The new online network can be found at www.unep.org/climateneutral.
