Conférence du professeur Carlo Carraro organisée par le département de Géosciences. Carlo Carraro est Vice-président du Working Group 3 du GIEC (IPCC en Anglais) pour le 5ème rapport (celui de 2014).
Il présente ici les premières conclusions et propositions découlant des négociations sur le changement climatique avant et pendant la COP21.
International negotiations on climate change control are moving away from a global cooperative agreement to adopt a bottom-up framework composed of unilateral pledges of domestic measures and policies (the so-called INDCs). This shift from cooperative to voluntary actions to control GHG emissions already started in Copenhagen at COP 15 in 2007 and became a platform to be formally adopted by a very large number of countries in Paris at COP 21. The emerging architecture calls for a mechanism to review the intended contributions of the various signatories and assess their adequacy. Most importantly, countries’ voluntary pledges should be compared to determine the fairness, and not only the effectiveness, of the resulting outcome. This assessment is crucial to support future more ambitious commitments to reduce GHG emissions. In addition, in the case the assessment of INDCs reveals their inadequacy, countries will be asked by the UNFCCC to increase their efforts through enhanced contributions in future negotiations. For all these reasons, it is crucial to properly assess and compare the INDCs. This lecture is a first attempt into this direction. A preliminary set of results to compare the effectiveness and fairness of the INDCs submitted by the major GHG emitting countries will be proposed.
