Tripling global renewable capacity by 2030, as agreed and endorsed by 196 nations at COP28 in Dubai: issue 50 of RM is focused upon this ambitious goal. An overview of the state of the energy transition, from old hydropower to new technologies for solar and wind, from ocean energy to cutting-edge research on nuclear fusion.

ESG ratings, climate finance, biodiversity funds, venture capital, carbon market, cryptocurrencies, reform of financial institutions, green bonds, and insurance. Through the voices of experts from around the world, with investigations and insights, RM49 focuses on the strategies that will be needed to make good use of the economic resources needed for a just transition.

Predicting extreme events, planning the energy transition, managing infrastructure and cities, and accelerating climate and biodiversity research. There are countless challenges where artificial intelligence and digital systems can now assist us along the path to sustainability. RM #48 explores the revolutionary potential of these cutting-edge technologies, yet considering their impacts and the darker side of the coin.

Humankind's relationship with trees and forests has always been controversial. While today our understanding of the importance of forests to the health of the planet has reached startling clarity, the extractive race driven by agribusiness and mining continues to devastate these precious habitats in every part of the world. In this issue of RM, a search for a balance that is possible and increasingly urgent has been undertaken.

Based on the "polluter pays" principle, extended producer responsibility (EPR) is one of the pillars for the development of a real and effective circular economy. However, its application, while well proven in some sectors (packaging, lubricating oils, tires), is still lagging behind in most industrial branches. With RM46 we examined the topic in depth and on a global scale, with interviews with international experts, case studies and an exclusive reportage.

The ocean is still an undiscovered world, yet it accounts for 90% of the biosphere, covers 71% of the earth's surface, absorbs 50% of greenhouse gas emissions and provides more than 50% of the oxygen we breathe. It is also a source of sustenance and development for human civilisation, as long as its balance is not compromised. Issue 45 of Renewable Matter is a voyage into the complicated relationship between man and the sea, following the route of an increasingly sustainable blue economy.

Nowadays, the European Union is based on a new vision of development, hinging on decarbonisation, circular economy, biodiversity protection and green cities.

A monographic issue, produced in collaboration with the European Economic and Social Committee and previewed Brussels, on the occasion of the Circular Economy Stakeholder Conference.

Critical raw materials are fuelling a new extractivist race. The demand for metals and minerals essential for the energy and digital transition will increase by 500% by 2050. RM43 - with interviews with experts and institutions from all over the world and a photo reportage by Stefano Stranges - offers a 360-degree overview of CRM, from the geopolitical and technological framework to the new frontiers of mining, from the illicit trade in e-waste to circular solutions to reduce mining reliance.

The circular transition requires technologies and technical skills as well as soft skills of all kinds. New types of knowledge are needed, that correspond to professional figures offering services to help companies, governments, communities and individuals navigate the processes of change for the decarbonisation of the economy. Issue 42 is dedicated to them: researchers, educators, developers, communicators, storytellers, analysts, consultants and creatives. All at the service of the circular economy.

The retail sector wants to change. The environmental crisis and new political and macroeconomic scenarios are bringing new currents of thought to the shelves of the large-scale distribution sector, which is now facing the challenge of sustainability, efficiency, and circularity. Well-equipped with a shopping cart, in issue 41 of Renewable Matter we took a look at how the food market is changing and what the supermarkets of the future will ultimately be like.

Issue 40 of Renewable Matter is dedicated to the most precious of resources, the most important of 'materials'. Water is at the heart of any thought on sustainable development: a source of life, energy, and biodiversity, it is both a victim and weapon of climate change. This is why its sustainable, circular, and equitable management will be increasingly fundamental for the future of the Planet.

Due to the double environmental and pandemic crisis, the fashion sector is experiencing a rapid transformation. From the attention to the use of more sustainable and circular materials to business and consumption models (rental, second hand) to the consumers tastes, every aspect of the fashion system is at stake. RM39 takes stock of the revolution underway.

With a carbon emission rate of 36% of the global total, construction is today the Achilles heel of decarbonisation. Although the sector has always been energy-intensive and with a high consumption of materials, it is now facing a revolution in the direction of sustainability and circularity. From the New European Bauhaus to the materials passport, MR38 searches for innovations, ideas and solutions for a new way of building.

Rethinking food systems from an integrated perspective, tying together biological, geographic, social, economic phenomena, is now vital, both to heal distortions and inequities, and to prevent our way of producing food from destroying biodiversity and contributing to climate crisis. MR37 addresses the issue with a transdisciplinary approach, proposing scientific analyzes and cultural visions, from regenerative agriculture to circular supply chains.

Very few events such as the Covid-19 crisis have led to a rethinking of large urban structures, to understanding connections amongst health, resilience, sustainability and prosperity. The cities of the future will need to be more resilient and more circular. RM36 is a journey around the world - from the Netherlands to Colombia, from the United States to Italy, from Indian slums to European cities - to discover projects, visions and experiences that are applying this transition.

While the traditional textile system still has a huge environmental impact, the outdoor sector is at the forefront of embracing a circular path. This issue looks into the circular innovations of the sector with international case studies: from materials, such as recycled fabrics and bio-fibers, to new business models, such as clothing and equipment rental and repair.

Transport is a top priority for decarbonisation strategies. But the transition to electric transport is not enough: alternative fuels, especially biofuels and hydrogen, will play a key role in the next decade. Alexandru Floristean of Hydrogen Europe and Elisabetta Tola write about it, among others, in a dense number of inquiries and interviews on the future of the transport system.

The food system needs a circular revolution to become more sustainable.
