L'urgence climatique est une conséquence directe de l'utilisation des terres et de l'agriculture, des transports, des bâtiments et des processus industriels à forte intensité de carbone, ainsi que des sources d'énergie polluantes. En l'absence de changements profonds dans ces secteurs et d'une réduction drastique de l'empreinte carbone, il y a peu d'espoir de protéger la planète des effets dévastateurs d'un monde plus chaud.
Ce flux en direct vous tiendra au courant de toutes les dernières nouvelles de la Conférence des Nations Unies sur le changement climatique, connue sous le nom de 29e Conférence des Parties (COP29) à la Convention-cadre des Nations Unies sur les changements climatiques (CCNUCC), qui se tiendra à Bakou, en Azerbaïdjan.

Questions remains as negotiators head into final days
UN Climate Change/Kiara Worth
Negotiations over COP28's final agreement are ramping up as government ministers begin to start meeting to whittle down the text.
Questions remain whether countries will agree to "phase down" or "phase out" fossil fuels, with five days left of negotiations. More than 100 countries support adding text referring to a "phase out" and the science is clear: without the phasing out of fossil fuels, the Paris Agreement goals cannot be met.
Some positivity emerged earlier today when it was revealed that the COP28 President had asked Canada to help to develop language on the potential phase down or phase out of fossil fuels. Yesterday Canada announced it would require its fossil fuel industry to cut its emissions between 35 per cent to 38 per cent below 2019 levels starting in 2030.
The aim is to have a text finalised by the end of the day on Tuesday, although previously COPs have often gone on deep into the early hours of of the morning.

Transport transition needs to be inclusive, cleaner and safe
Ox Delivers
Speaking at COP28 today, UNEP Executive Director Inger Andersen said: "Transport is a big driver of emissions. As electric vehicle sales surge globally, we need countries to continue to lead and speed up this transition. It’s a win win: new jobs, clean air and climate action."
Later she also talked about the importance of a inclusive, clean and safe transport transition: "Hundreds are killed every day on roads across Africa. We need a transport revolution that is inclusive, cleaner and safe. Active mobility policies and infrastructure can allow everyone to travel as they need while we meet our climate goals.
One African country that has made progress in transitioning to electric vehicles is Rwanda.
The country of 13 million has in recent years introduced tax breaks for EV buyers, cultivated local electric vehicle makers and unveiled ambitious plans to electrify public buses. The changes are part of the country’s efforts to curb rising air pollution and cut down on the greenhouse gas emissions that are driving climate change.
“E-mobility is one of the transport decarbonization initiatives the government has undertaken,” says François Zirikana, an e-mobility specialist with the City of Kigali. “Other initiatives include Kigali bike share scheme as well as car-free zones and car-free days.”
Buildings Breakthrough aims to drive urban climate action
UNEP/Duncan Moore
The Buildings Breakthrough will see countries joining forces to accelerate the transformation of the sector – which accounts for 21 per cent of global greenhouse gas emissions – with a view to making near-zero emissions and climate resilient buildings the new normal by 2030.
Under the Buildings Breakthrough, the UNEP/GlobalABC secretariat, the International Energy Agency and the International Renewable Energy Agency, together with the High-level Climate Champions, will undertake an annual assessment of global progress in the sector, closely aligned with the UNEP/GlobalABC annual Global Status Report for Buildings and Construction.
At COP28, UNEP extended an open invitation to nations worldwide to join the Buildings Breakthrough and unite in this global effort towards near-zero emission and resilient buildings by 2030. So far, 27 countries have pledged their commitment to the Buildings Breakthrough.

Five ways cities can cool down while cutting emissions
Cooling is a double burden on the climate: air conditioners and refrigerators have both indirect emissions from electricity consumption and direct emissions from the release of refrigerant gases, the majority of which are much more potent at warming the planet than carbon.
By 2050, unless humanity dramatically lowers its emissions of climate-altering greenhouse gases, close to 1,000 cities will experience average summer highs of 35°C, nearly triple the current number. The urban population exposed to these high temperatures could increase by 800 per cent, reaching 1.6 billion by mid-century.
So, what are some alternatives to air conditioning that can help keep people cool without leading to a rise in emissions? Here are five examples from around the world.
The event will explore and showcase how AI and related technologies can be harnessed to tackle climate challenges, such as predictive modelling, climate data analysis, and ensuring efficient management of resources.
It will also discuss the potential negative effect of unregulated AI on the climate and reinforce the importance of ethics. Finally, it will explore the transformative potential of Artificial Intelligence in addressing climate change challenges.
November hottest month on record as climate records keep breaking

Europe’s climate monitor, the Copernicus Climate Change Service announced today that November had become the sixth record-breaking month in a row for average temperatures. It was 1.75°C warmer than the pre-industrial average, with 2023 1.46°C above the pre-industrial average, making it the hottest year on average since records began.
November also contained two days that were 2°C warmer than pre-industrial levels, which has never happened before. Indeed scientists say that 2023 could be the warmest in more than 100,000 years.
With COP28 at its mid-point, negotiators are about to start to whittle down the text, with most hoping there is a mention of a fossil fuel "phase-out" in the final agreement. The science is clear that there needs to be a huge drop in fossil fuel burning if the Paris Agreement goals are to be reached.
Earlier today, 75 scientists published an open letter in which they highlighted what needs to happen to reach net-zero emissions by 2050: "Scenarios consistent with this goal require a complete phase-out of coal by 2050 and rapid phase-down of oil and gas (halved every decade). After 2050 the world needs to rapidly move into net negative emissions, particularly after a number of decades of 1.5°C overshoot."

How AI is helping tackle environmental challenges
UNEP
We can't manage what we don't measure, goes the old business adage. This rings true more than ever today as the world faces a triple planetary crisis of climate change, nature and biodiversity loss, pollution, and waste.
More climate data is available than ever before, but how that data is accessed, interpreted and acted on is crucial to managing these crises. One technology that is central to this is Artificial Intelligence (AI).
So, what exactly does AI mean?
"AI refers to systems or machines that perform tasks that typically require human intelligence, and can iteratively improve themselves over time, based on the information they collect," says David Jensen, coordinator UNEP's Digital Transformation sub-programme.
Jensen highlights several areas where AI can play a role in tackling environmental challenges, from designing more energy-efficient buildings to monitoring deforestation to optimizing renewable energy deployment.
"This can be on a large scale – such as satellite monitoring of global emissions, or a more granular scale – such as a smart house automatically turning off lights or heat after a certain time," he adds.
