Ministerial-level talks began on Tuesday at the ongoing Cancun climate conference, signaling a call by top United Nations officials for delegates to iron out definitive measures on climate mitigation, adaptation and financing in the final three days of negotiations. At the opening ceremony, UN Secretary General Ban Ki-Moon said that the COP16/CMP6 conference must represent a breakthrough in multilateral efforts to reach a new international framework to fight global warming.

The Agreement for Cooperation on Climate Change between the governors of the Yucatan Peninsula was signed at the Great Parnassus Hotel in the framework of the COP16/CMP6. The governments of Quintana Roo, Yucatan and Campeche participated in the Declaration. The Yucatan Peninsula is a region of challenges and opportunities. It houses 22% of the birds in the country, 40% of mammals, 24% of mangroves and has the second largest ecological reserve in Latin America. It is a particularly vulnerable region because of its geographical location, but also a focus of attention because of its forest reserves that are a natural way of mitigation

Greenhouse effect gases (GHG) emissions produced during the 16th Conference of the Parties (COP16) will be totally neutralized, assured Hernando Guerrero Cázares, Advisors Coordinator of Mexico’s Ministry of Environment and Natural Resources (Semarnat). “We have worked in all aspects of the sustainability of this event”, he said. “Every participating country will receive a formal certificate which states that all emissions generated during their stay were neutralized.”

Jose Ángel Cordova Villalobos, Mexico’s Secretary of Health, said in the conference Climate Change and Health: Challenges and Opportunities, held at the Mexico Pavilion at the Cancunmesse venue, that there is scientific evidence that the effects of this weather phenomenon affect human life and the welfare of people, so it is "clear that there is a negative relationship between Climate Change and health."

Save water was the message left by the launching of the call to the Eco Film Festival in the Cancunmesse center, one of the venues of COP16. This Festival is a project of the Nature Man Foundation, which proposes to raise awareness of both young and adults about the most significant environmental problems through an annual short film competition.

The corridors of the headquarters for COP16/CMP6 have constant activity of delegates 24 hours a day; they have the opportunity to tell their stories using the telecommunications network installed expressly for this occasion. Also, aware of the importance of not increasing the carbon footprint during the Conference, they make use of bicycles offered to travel the distance between the Moon Palace hotel rooms, transfers that become easy and enjoyable.
