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.

New report: Finance needed to protect, restore nature three times less than needed
The Big Nature Turnaround – Repurposing $7 trillion to combat nature loss report is an annual report that tracks global financial flows – both positive and negative – to Nature-based Solutions (NbS) and estimates the investment needed to limit global warming to below 1.5°C, halt biodiversity loss and achieve land degradation neutrality.
The report, published earlier today, highlights the fact that public funding and private investment into nature-based solutions is at least three times smaller than it needs to be to tackle the biodiversity, land degradation and climate crisis.
The amount of money governments spend that negatively impacts nature, is 10 times higher than amounts spent on or invested in nature-based solutions.
Doubling or tripling nature-positive expenditure will not solve the crisis, unless the far higher nature-negative expenditure is also tackled. For example, despite pledges by governments to reduce fossil fuel subsidies, these have doubled from US$563 billion in 2021 to a staggering US$1.1 trillion in 2022.
Nature, Land Use and Oceans Day will focus on scaling robust solutions that protect, restore and effectively manage natural ecosystems and forests, address drivers of nature loss, empower Indigenous Peoples and local communities, and create resilient livelihoods.
UNEP Pavilion:Finance for nature: Unleashing a $7 trillion opportunity for realignment
UNEP will launch the third edition of its State of Finance for Nature Report which tracks the global financial flows towards Nature-based Solutions and estimates the investment required to limit global heating to below 1.5°C, halt biodiversity loss and address land degradation. The event will centre around a series of strategic actions intended to act as drivers for governments, finance institutions and the private sector to close the finance for nature gap.
UNEP Pavilion:Everything all at once: High-level dialogue on supercharging forest solutions to the climate crisis
The race to decarbonization requires an ‘everywhere, everything, all at once’ approach. Beyond the transport and energy sectors, forests offer an untapped mitigation potential of at least 4 gigatonnes of emissions reductions per year. Forests also have enormous potential to generate resources for the communities that inhabit them. This event will bring together forest-rich countries and experts to discuss solutions, including the role of carbon markets, monitoring systems, and safeguards framework to supercharge the impacts of forest-based climate action.
UNEP event: High Level Event on Artificial Intelligence for Climate Action
This event will provide a space for policy discussion, awareness raising and exchange of knowledge and experience on opportunities and challenges of AI-powered climate solutions. The event will discuss various aspects of the application of AI for climate action to help accelerate the implementation of the Paris Agreement.
The event will highlight the pivotal role of ecosystem restoration in addressing global environmental challenges. This event will serve as a platform for showcasing the achievements and success stories of the UN Decade on Restoration, focusing on its general outcomes and the establishment of a digital hub for knowledge sharing and collaboration.
UNEP Pavilion:Climate Action Showcase: Beyond carbon – realizing untapped potential of forests to combat climate changes
From lowering temperatures to providing renewable materials, livelihoods and employment, the world’s forests play a larger role than just cutting carbon emissions. The Collaborative Partnership on Forests – made up of 16 international organizations – recently unveiled its Joint Call to Action for Forests towards 2030. This event will focus on best practices and case studies as well as highlighting the potential of renewable materials and green jobs.
UNEP Pavilion: Launch of Amazonia Viva in 4D: a virtual journey into the heart of the forest
Throughout COP28, come experience the award-winning virtual reality film, Amazônia Viva, a 10-minute film that transports viewers to the Tapajós River region of the Brazilian Amazon. The 360° immersive virtual reality experience unveils one of the most important ecosystems on the planet. Raquel Tupinambá, a cacique indigenous leader from the Surucuá community, welcomes the viewer into her homeland and guides them through a fully interactive virtual journey. Along the way, the majesty of the world’s largest rainforest is revealed, as are the imminent threats it faces.
UNEP event: Driving Integrated implementation of national climate and biodiversity frameworks for 2030 action
This event will see panellists discuss the importance, challenges, and opportunities in adopting a joined-up approach in the design and implementation of national climate and biodiversity plans and strategies, in support of achieving the goals of both the Paris Agreement and the Kunming-Montreal Global Biodiversity Framework, as well as the Sustainable Development Goals.

As the world’s population grows, so does the demand for animal-sourced foods like meat and dairy. The challenge: animal agriculture can be environmentally destructive, worsening the triple planetary crisis of climate change, nature and biodiversity loss, and pollution and waste. But a new report from UNEP finds there are more sustainable ways for humanity to source its protein.
The report, launched today, casts a spotlight on a range of increasingly popular animal protein alternatives, from lab-grown meat to fermented fungi.
The report finds that by 2050, meat and dairy alternatives could make up as much as half the global market for animal proteins. Here’s a closer look at some of these culinary innovations and how they can help create more sustainable food systems.

What if 1.5°C is missed?
UNDP Climate
With COP28 negotiations heading into their critical, final few days, it can sometimes get lost that in all the abstract language and politicking, the effects of the decisions made at COPs have profound, real-world consequences.
Illustrating this, the Guardian has run an interesting article on the difference between a 1.°5 world and a 2.°C world. It interviewed five climate scientists about what that difference would mean for food, water and conflict; marine ecosystems; the Amazon and terrestrial biodiversity; sea level rise; and adaptation and the value of compensation. Read some excerpts below:
Food, water and conflict
Seventy million more people in Africa are projected to suffer acute food security at 2°C than 1.°5C, according to Catherine Nakalembe, who heads the Africa programme of Nasa Harvest.
Sea level rise
The existence of the most low-lying nations potentially depends on the half-degree between 1.5°C and 2°C, which will add at least 10cm to sea level rise by the end of this century, leaving an extra 10 million people at risk of flooding and storm surges.
Terrestrial biodiversity
At 2°C, 18 per cent of insect species, 16 per cent of plants and 8 per cent of vertebrates are projected to lose half of their habitats, at least double the proportions at 1.5°C.
Marine ecosystems
At 1.5°C, it may already be too late to save [coral reefs] in the Caribbean and parts of the western Indian Ocean. This would leave between 10 per cent and 30 per cent remaining in good health. At 2°C, the survival rate goes down to between 1 per cent and 10 per cent as the healthy patches become more isolated, vulnerable and unable to reproduce.
Air pollution causes 1 in nine deaths globally and the climate crisis and air pollution are inextricably linked. Pollutants such as black carbon and methane contribute to global heating and reduce air quality.
The Climate and Clean Air Coalition is a UNEP convened voluntary partnership of more than 160 governments, intergovernmental organizations, and NGOs working to reduce powerful but short-lived climate pollutants (SLCPs) – methane, black carbon, hydrofluorocarbons (HFCs), and tropospheric ozone – that drive both climate change and air pollution.
The meeting will also see the launch of the Clean Air Flagship which aims to bring more attention to the global air pollution crisis, highlight readily available solutions, elevate ongoing regional collaboration, strengthen government cooperation, and offer direct support to countries.
Freshwater Challenge event highlights importance of ecosystem

Sunday is Food, Agriculture and Water Day at COP28, and one of the day’s events is a meeting about the Freshwater Challenge, which will see new country signatories announced, highlighting their commitment to protecting and restoring freshwater ecosystems, which are essential to mitigating and adapting to climate change, and which are currently the most degraded type of ecosystems worldwide.
The Freshwater Challenge is the world's most ambitious freshwater restoration initiative and aims to restore 300,000km of rivers – equivalent to 7 times the Earth's circumference – and 350 million hectares of wetlands – an area larger than India – by 2030.
One-third of the world’s wetlands have been lost over the past 50 years, and and they are being lost still faster than forests. Rivers and lakes are the most degraded ecosystems in the world, with fish populations, many of which are vital for community food security, pushed to the brink.
FAO report reveals agrifood industry's contribution to climate crisis

The Food and Agriculture Organization of the United Nations (FAO) released a report today revealing that in 2015, livestock agrifood systems – including farm production activities and some key supply chain processes such as land use change related to feed, transport and input manufacturing – accounted for approximately 12 per cent of all anthropogenic GHG emissions and about 40 per cent of total emissions from agrifood systems.
The report highlights a number of solutions to reduce the sector's emissions including increasiing agroforestry and optimized rotating grazing, and boosting animal health.
So, how much do you know about the global food system?
Indigenous Peoples call for protection during green energy transition

More than 100 Indigenous Peoples groups and NGOs have called for their rights and land to be protected in an open later released today at COP28.
They want COP28 to be a "platform to discuss Indigenous Peoples’ rights in the context of the increasing demand for minerals mined for energy storage, electrified transportation batteries, and other green energy technologies."
The letter also highlights the fact that "many Indigenous leaders are pursuing and championing clean energy and transportation solutions on their territories that align with their self-determined needs and goals. These Indigenous-led solutions need to be acknowledged, recognised, promoted, and funded by States and private entities."
On Now: Launch of report on alternatives to conventional animal products
Food systems are responsible for about 30 per cent of current manmade GHG emissions, while animal products account for almost 60 per cent of those emissions.
There is a need to change the way we produce and consume the food we eat because of its growing impact on climate change, particularly in high- and middle-income countries.
While many approaches are available to address the adverse impacts of animal agriculture, this report – the latest in UNEP's Frontiers series – looks specifically at novel alternatives to conventional animal source food.
The importance of children and youth in climate action
Connect4Climate
One of today's focuses at COP28 is on youth, children, education and skills. We know that today's children and youth will be impacted hugely by the climate crisis in the coming years and decades, and so today aims to explore investment in youth-led innovation and entrepreneurship, inclusion in policymaking processes capacity-building, and transforming education to close the skills gap for green jobs aligned with climate action.
UNEP has long championed the rights of youth to a sustainable environment and has increasingly involved them in the process.
A child-friendly version of the Principles and Guidance on Children’s Right to a Healthy Environment in the ASEAN Region was released in response to one of the ten Principles, which stated that children must have “access to age-appropriate, gender-sensitive, localised and contextualised information.”
