COP30 | Riccardo Valentini: Forests, from carbon sinks to engines of a Green Economy

As COP30 opens in Brazil, attention turns once again to the world’s forests – not only as carbon sinks, but as living systems vital for the planet’s health and for sustainable development. According to IPCC author and forest ecology expert Prof. Riccardo Valentini, stopping deforestation is no longer enough – we need a new global paradigm for more sustainable forest management, agriculture, and land use. “Tropical Forests Forever Facility (TFFF) could open a new phase for the green economy, linking forest protection with real economic returns through carbon markets and sustainable business investments,” he says. “But without political will, it risks becoming another empty pledge.”

Putting out the blaze: Wildfire risk management begins well before fire season

As of July 2025, almost 300,000 hectares of forest – an area larger than Luxembourg – has gone up in flames in Europe. What is more, the number of wildfire events could increase by 50% globally by the end of the century due to a combination of changes in climate and land use and management. These threats will tend to concentrate in hotspots such as the Mediterranean, where over 80% of European wildfires occur and which experienced upwards of 2.5 billion euros in wildfire related damages in 2022 alone.

Twice the work in half the time: EU calls for 90% cut of GHG emissions by 2040

The European Commission set an intermediate step on the path to 2050 climate neutrality. An incredibly detailed impact assessment explains how member states would concretely reach this ambitious goal.

Ambitious and realistic. Europe’s path to decarbonization

Linda Kalcher, Executive Director of the think tank Strategic Perspectives, outlines strengths and weaknesses of the EC recommendation of reducing 90% net EU greenhouse gas emissions by 2040 and describes opportunities and shapes of a future that is just around the corner.

Democratizing climate modeling for more pertinent and accurate policy insights

Integrated Assessment Models (IAMs) play a pivotal role in shaping climate research and policy. “The main progress lies in democratizing modeling capabilities across different countries, ensuring more pertinent and accurate policy insights,” says Roberto Schaeffer. The need for a shift towards national-level modeling of climate impacts, the complexity of balancing immediate costs with long-term benefits at the policy level, and the representation gap between countries, are at the core of the current discussion around climate modeling.

At the root of the net-zero myth

The origins, future and feasibility of net zero. “Net-zero is a powerful idea but it has to be understood as a systemic concept, related to the fact that temperatures will stop increasing once global CO2 emissions reach zero,” says Massimo Tavoni, director of the CMCC European Institute on Economics and the Environment.

COP28 | MARIA VINCENZA CHIRIACO’. Agriculture, forests and land use: Here it is the future of carbon sequestration

The Agriculture, Forestry, and Other Land Use (AFOLU) sector is playing a pivotal role in the ongoing climate discussions at COP28, constituting not only a significant contribution to climate change but also possessing substantial potential for its mitigation.

Can AI help nourish a sustainable food system?

The democratization of technology and the ability of AI driven models to better process both quantitative and qualitative data is opening new opportunities for the food system to become both more productive and sustainable.

Climate-related disclosure: Bridging the data gap

High quality data is essential if we are to achieve our global climate related goals. Sue Armstrong-Brown, Global Director of Environmental Standards and Thought Leadership at CDP, explains how data obtained through disclosure informed the Global Stocktake to be agreed at COP28 and how the world is taking action to fill the shortage of climate-related information.

Agricultural innovation in the age of climate change: For sustainable agri-food systems.

Accounting for 30% of total global greenhouse gas emissions, agriculture’s connection with climate change is intricate. At the same time, “The real challenge for agriculture in the next few decades will be climate change,” says FAO’s Francesco Tubiello. “Without strategic interventions the goals outlined in the Paris Agreement cannot be met.”

Finance, resilience, action: Three climate keywords for Africa

Africa stands at the forefront of the disproportionate impacts of climate change despite having contributed minimally to global greenhouse gas emissions historically. In September, the first Africa Climate Summit aimed at finding common finance solutions to foster a green and sustainable growth for the continent. The results are summarized in the Nairobi declaration, highlighting the urgency of a strong climate finance strategy, throughout the continent and at an international cooperation level.

Building on sustainable foundations: Climate change and energy efficiency to decarbonize the construction sector

The link between buildings and climate change has long been a focal point of global discussions on mitigation and adaptation. A new report by UNEP and Yale addresses the urgent need to decarbonize the construction sector, responsible for more than one third of global CO2 emissions. With global emissions on the rise, this report provides a blueprint for reducing “embodied carbon” emissions from building materials by 2050. Expert Paolo Bertoldi highlights that creating a sustainable building industry is possible and needs collaboration across sectors and countries.
