Join us for Rio+C40 via live webcast

The newly launched platform – featuring innovative, rich web-based technologies – is just part of our vision to strengthen the ability of the network of C40 Cities to communicate and broadcast the important work of cities around the world.

In this spirit, we would like to invite you to join us tomorrow, June 19th for Rio+C40: Megacity Mayors Taking Action on Climate Change via a full-day, live webcast on via Ustream. 

The event, co-hosted by C40 and the City of Rio de Janeiro, features mayors and leaders from cities around the world in roundtable conversations that reflect the key themes of Rio+20. The actual sessions are open only to invited city delegations and select partner organizations, but through webcast, everyone is able to watch.

We encourage you to not only tune in throughout the day, but to share this event with your colleagues and friends as well. Sharing the webcast is simple:

PLEASE NOTE: until the stream goes live on June 19th, the player will indicate that it is “Off Air.” Once we begin the feed, the player will start broadcasting.
