Focus sur l'action climatique

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.

Happening today: Reimagining Urban Growth

Event poster

During the Green & Resilient UrbanShift Africa Forum, leaders from across the continent united to learn and share insights on accelerating transformative urban planning approaches—and the finance needed to implement them. Read more. 

As African cities are set to double in population over the next few decades—and with one in every four people projected to be African by 2050—it's no exaggeration to say that people working now to advance sustainable and resilient urban planning hold both enormous responsibility and potential.


Register to attend this webinar on how to scale nature-based solutions for climate resilient cities.

Sixty-second session of the IPCC

The Intergovernmental Panel on Climate Change (IPCC) finalized the outlines for the three Working Group reports that will contribute to its Seventh Assessment Report (AR7) during its recent 62nd Plenary session in Hangzhou, China. These reports will cover:

  1. The physical science basis of climate change
  2. Impacts, adaptation, and vulnerability
  3. Mitigation of climate change

The Panel also approved the 2025 budget and will now begin selecting experts to serve as authors for these reports. Additionally, the Synthesis Report, which will integrate findings from these reports along with a Special Report, is expected to be released in late 2029.

The Seventh Assessment Cycle, which started in July 2023, includes:

  • A Special Report on Climate Change and Cities (due March 2027).
  • A Methodology Report on Short-lived Climate Forcers (due late 2027).
  • A Methodology Report on Carbon Dioxide Removal Technologies, Carbon Capture, and Storage.

The IPCC’s Sixth Assessment Report (AR6) was completed in March 2023, providing key scientific input to global climate policy discussions, including COP28. Read the closing press release.

With new climate plans, countries could supercharge growth, fight poverty, say experts

Later this year, dozens of countries that have signed the Paris Agreement are due to submit new national climate plans, or Nationally Determined Contributions. Done right, experts say these plans could not only rein in the greenhouse gases driving climate change. They could also serve as blueprints for reducing poverty, improving human health, bolstering food security and expanding energy access, all while creating trillions of dollars in investment opportunities. 

“When we talk about climate change, we usually talk about what we stand to lose as the planet warms,” says Martin Krause, Director of the Climate Change Division at the United Nations Environment Programme (UNEP). “But we need to talk more about the society-altering gains we could make by addressing climate change.” 

Read about the biggest benefits of climate action, according to the experts.

Key takeaways from the UrbanShift Africa Forum

The UrbanShift Africa Forum, held in Nairobi from February 17 to 19, 2025, brought together over 250 leaders from African cities, including mayors, policymakers, investors, and business leaders. The event focused on sustainable urban development amidst the continent's rapid urbanization.

Key takeaways:

  • Urgent need for climate financing: With 92% of African cities at extreme climate risk, leaders emphasized the necessity for increased climate financing to support resilient infrastructure and sustainable growth.
  • Youth engagement: Recognizing that approximately 70% of Africa's population is under 35, the forum highlighted the pivotal role of youth in driving technological innovation and entrepreneurship for a sustainable future.
  • Collaborative efforts: The event underscored the importance of partnerships between local governments, national authorities, and the private sector to effectively address urban climate challenges.

As Africa is poised to lead global urban growth in the coming decades, the insights and commitments from the UrbanShift Africa Forum are crucial steps toward building resilient, inclusive, and sustainable cities for future generations.

Nairobi’s Luthuli Avenue Leads in Sustainable Mobility

As part of UrbanShift in Africa Forum, city officials and urban planners explored Luthuli Avenue, now a model for sustainable urban mobility. Once congested, the street now prioritizes cycling lanes and pedestrian walkways, targeting up to 50% reduction in vehicle emissions and promoting cleaner air and better public health.

With climate-proofed infrastructure, the project prevents urban flooding and supports a cooler, more resilient city. The air quality monitoring provides the evidence base to eventually create the first carbon-neutral street in the region, signaling the potential of this project to lead toward a transformative impact on the fabric of the city.

What is the UrbanShift programme?

UrbanShift is a programme funded by the Global Environment Facility and led by the UN Environment Programme that supports more than 20 cities in Asia, Africa and Latin America to adopt integrated approaches to urban development, helping shape cities that are efficient, resilient and inclusive.
