From the UNFCCC:
The UN Climate Change Secretariat and the Host Government would like to inform all journalists covering COP 15 of the following:
The maximum capacity of the Bella Center, the venue of the UN Climate Change Conference, is 15,000. More than double that number – 34,000 thousand – have asked to physically attend the meeting. Due to these contraints, NGO delegates will be allowed access to the building according to a quota system that was implemented at the most recent UNFCCC gathering in Barcelona in November. According to this system, only a prearranged percentage of each organistation’s representatives will be allowed access to the building during peak times.
Also due to the space constraints, a maximum of 3500 journalists will be allowed access to the Bella Center at this point in time. This number has already been reached. The situation will be reassessed 9 December. Should there be a possibility to accommodate more journalists, a corresponding notification will be issued that day.
