Paris climate talks by the numbers

Paris: UN climate talks ended Saturday with a historic commitment to fight global warming. 

The 13-day talks, with more than 40,000 daily participants, comprised a massive logistical challenge.

A few key numbers:

The number of heads of state and government who attended the opening ceremonies. 

Member nations of the United Nations Framework Convention on Climate Change (UNFCCC). 

Hectares (45 acres) of the venue, located just north of Paris in Le Bourget. 

Tonnes of greenhouse gas produced by the conference, equal to the annual carbon dioxide (CO2) emissions of 4,420 cars over the course of a year. France has vowed to "offset" this pollution by supporting pro-climate initiatives.

The number of meals served.

The number of police and gendarmes responsible for security at the conference. 

The number of additional places created on public transport in the Paris area during the conference. Plus 200 electric cars to ferry conference delegates. 

The budget, in euros ($180-196 million), that France has set for the conference.
