A new panel of experts, including top climate scientists, is urging governments to develop science-based and just roadmaps for phasing out fossil fuels. The panel's recommendations were presented in Santa Marta, Colombia, ahead of a ministerial meeting on transitioning away from coal, oil, and gas. The panel emphasizes the need for whole-of-government plans to overcome barriers to the energy transition. A draft roadmap for Colombia, developed with input from European scientists, shows a pathway to economic and societal benefits through phasing out fossil fuels with energy efficiency measures and renewable energy. Developing countries need an exit route from the "debt trap" of fossil fuels to enable a just and effective transition. Brazil is working on a national roadmap for its economy and leading a global roadmap for climate solutions, with the new panel aiming to provide more specific and targeted advice at a faster pace than the IPCC. The transition beyond fossil fuels depends on cities and collective action, with recommendations including banning new fossil fuel infrastructure and implementing carbon levies on imports. The panel will be co-chaired by experts from Cameroon, Germany, and Brazil, and will consist of scientists working on transition pathways, technological solutions, policies, and finance.

Japanese scientists build all-perovskite tandem solar cell with 30.2% efficiency
Researchers at the University of Tokyo have developed an all-perovskite tandem solar cell using FAPbI3 nanoparticles, achieving 30.2% efficiency by combining a wide-bandgap top cell and a narrow-bandgap bottom cell. FAPbI3 is known for its high efficiency in solar cells but can transform into a non-functional phase, limiting performance. The researchers used a two-step method to fabricate the perovskite layers, stabilizing the material and improving durability. The four-terminal spectral splitting architecture of the device minimizes losses and efficiently utilizes the solar spectrum across both cells. The study suggests that carefully chosen spectral splitting wavelengths can lead to high efficiencies in both four-terminal and two-terminal perovskite solar cell architectures, with practical deployment options including outdoor photovoltaic systems and integration with concentrator photovoltaics.

Why the transition beyond fossil fuels depends on cities and collective action
The world must transition away from fossil fuels, but this requires structural transformation of economies and governance, not just technological substitution. Fossil fuels are deeply embedded in economic systems, leading to financial and institutional incentives that favor short-term extraction. Cities play a crucial role in accelerating the transition by reshaping demand, accelerating innovation, and demonstrating that a different model is possible. Transitioning away from fossil fuels not only lowers costs and improves public health, but also rebuilds trust in public institutions. Cities like Melbourne, Curitiba, Johannesburg, and Bogotá are taking significant steps towards reducing fossil fuel use and increasing renewable energy capacity, part of a global effort to halve fossil fuel use in C40 cities by 2030. The First Conference on Transitioning Away from Fossil Fuels in Santa Marta aims to bring together various stakeholders, including cities, to identify concrete pathways for a just and equitable transition, focusing on transforming energy supply and demand, overcoming economic dependence, and strengthening international cooperation to redefine development in a sustainable way. The message from Santa Marta is that the end of the fossil fuel era is already underway, and the focus now should be on ensuring a just, coordinated, and irreversible transition.

Dutch buildings could host 36 GW of façade solar capacity
The Netherlands Enterprise Agency (RVO) report highlights the potential for building façades to offer up to 36 GW of solar PV capacity in the country, particularly in buildings with unsuitable roofs or where architectural considerations are important. While façade PV is currently a niche solution due to high costs and regulatory complexity, it can complement rooftop systems in space-constrained or grid-limited areas. To increase uptake, the study recommends a targeted approach focusing on rooftop PV and selective use of façade systems, with more demonstration projects, improved transparency on costs, simplified permitting processes, and better communication of financial incentives. Municipalities and national authorities are encouraged to lead by example by deploying façade PV on public real estate.

To phase out fossil fuels, developing countries need exit route from “debt trap”
At COP30, over 80 governments are proposing an initiative to address the debt crisis in the Global South by financing the transition to renewables with public grants instead of loans. The current debt architecture traps developing countries in a cycle where fossil fuel revenues are needed to service debt, hindering efforts to phase out coal, oil, and gas. Policy recommendations include debt cancellation and ending international finance for fossil fuel expansion to address climate challenges. Proper funding for renewable energy and diversification is crucial, as many countries in the Global South lack support for making the energy transition. The broken debt system must be fixed to confront future climate shocks and ensure a successful transition to renewable energy sources.
