s the leader of Indonesia, which has taken a leading role on climate change through its ambitious national emissions targets, President Joko '€œJokowi'€ Widodo is expected to attend this year'€™s COP21 climate summit, which will formulate historic global commitments on climate change.

The climate summit is considered extremely important, as it is expected to reach a new agreement binding all countries, from the developed world (including the US and EU) more responsible for the current CO2 in the atmosphere, to emerging and developing countries (such as Indonesia) that have significantly increased their emissions over the last few years.

French President Francois Hollande said on Sunday that heads of state had agreed to come to the Paris climate talks on the first day, Nov. 30, to ensure that '€œwe are able to sign an agreement at the end of the conference'€.

The appearance of heads of state will send a strong signal on the possibility of reaching a universally binding climate agreement, with climate scientists predicting that 2015 will be by far the hottest year on record following rising worldwide average temperatures.

However, doubts remain as to whether Jokowi will attend the Paris summit after he failed to show up to the 2015 Sustainable Development Summit in New York, US, in which world leaders from 193 countries pledged to tackle poverty, inequality and climate change by adopting the Sustainable Development Goals, 17 global goals that will provide the blueprint for the world'€™s development over the next 15 years.

'€œThe President has not decided whether [he] wants to go to Paris,'€ Vice President Jusuf Kalla, who is leading the Indonesian delegation at the Sustainable Development Summit, told reporters at the UN headquarters in New York on Sunday.
