You go for walks, maybe stretch out on an open couch, perhaps stand in long lines for a luke-warm bite to eat. You make numerous trips to the vending machines, munch on biscuits, chat with colleagues. Life in the fast lane of the COP15 Climate Conference in Copenhagen has slowed down to a crawl, and the waiting is most certainly the hardest part.

On the final day of the conference, the media — and everyone else — is looking forward to an outcome, any outcome of a two-week marathon that was supposed to lead to cuts in greenhouse gas emisions and a 2010 deadline for a legally binding treaty.

When you’re one of thousands of people trying to get a message out at once, you need an edge.

In Copenhagen during the COP15 conference a plethora of nongovernmental organizations, environmental groups, country delegations and even businesses have gone to sometimes unusual lengths to get their word out, and hopefully into the newspapers, or onto the Web and television.

The UN Conference on Climate Change is a weighty gathering of serious folks looking for a way to cut carbon emissions. It’s also a great place to bring some much-needed humor and along the way hammer a few perceived laggers in the fight against global warming.

Enter the Fossil of the Day Awards, a tongue-in-cheek dishonor first presented in 1999 and given to the countries with the worst performances at the previous day’s talks during UN climate conferences.

Walking through the Copenhagen airport, it’s pretty much impossible to miss the signs that illustrate the city’s focus is squarely on the climate. Those signs, literally, are everywhere, with advertisements adorning the walls on the walk from the flight ramp through to baggage claim and off into the arrivals area.

Big companies from Siemens to Shell are making sure you know they care.

Those are nice, but to really get a message across the big conglomerates may want to contact the ad guy for Greenpeace and its NGO alliance. The environment group has plastered the airport walls with a campaign “to mobilize civil society and to galvanize public opinion” to help bring about a new climate deal. The ad series features unflattering photos of world leaders like Germany’s Angela Merkel (pictured in the ad below), President Obama,  and others beside this quote: “We could have stopped catastrophic climate change” followed by the subtext “We did … nothing”. Whether you agree with the group and the alliance of NGOs participating in the ad, you gotta admit it’s pretty striking.
