Catalysing Economic Growth Through Powershoring
Industry on the road to 2050, 40-51.
In a trend called powershoring, energy-intensive industry will locate closer to renewable energy sources, driven by cheap renewable energy (which is difficult to transport), and the need to decarbonise. Regions’ […]
In a trend called powershoring, energy-intensive industry will locate closer to renewable energy sources, driven by cheap renewable energy (which is difficult to transport), and the need to decarbonise. Regions’ renewable energy resources and industrial capabilities shape the types of energy-intensive industries they can attract: some regions are best placed to produce very energy-intensive commodities (like green steel and green ammonia), while other regions are best positioned to host more complex industries that still require good clean energy supplies (like battery manufacturing or datacentres). Similarly, some powershoring industries have many spillovers and open up new pathways for regional economic growth, while other energy-intensive industries have fewer spillovers or open up fewer development pathways. This contribution explores these trends to help policymakers develop contextually aware powershoring strategies that can catalyse their best opportunities for economic development.

Economic Prosperity With Environmental Preservation
Cities in Amazonia: People and Nature in Harmony, 165-167.
The publication sheds light on the ongoing urbanization in Amazonia and emphasizes the need for urgent action to guide it towards sustainability, improving both forest protection and the well-being of its residents.
This book explores the complex and rapidly evolving urbanization of Amazonia, a vast, diverse, and ecologically critical region undergoing a profound transformation. Amazonia is now home to nearly 41 million urban residents across 895 settlements — and yet its urbanization remains poorly understood, underestimated in scale, fragmented in form, and frequently overlooked in policy.
Through multidisciplinary perspectives and contributions from more than 50 experts, this book examines how urban growth intersects with environmental degradation, social inequality, and gaps in governance. Despite these challenges, cities in Amazonia are also places of promising innovations, from tailored healthcare services and environmental monitoring to community-led planning and cross-border cooperation.
Rooted in both local insight and regional coordination frameworks, including the Amazonia Forever program, this work offers a holistic and evidence-based understanding of urbanization in Amazonia. It argues for urgent, coordinated action to guide sustainable, inclusive development — before current urbanization trajectories lead to irreversible ecological and social consequences. The book invites researchers, policymakers and practitioners to recognize Amazonia’s cities not only as sites of vulnerability but as key agents in shaping the region’s — and the planet’s — future.
Chapter four highlights successful practices and innovative approaches that address this region’s urban challenges. Some focus on people, improving healthcare, and mapping needs for riverine communities. Others emphasize environmental care, with cities leading sustainability efforts, nature-based solutions, partnerships and ecosystem restoration to boost resilience. It also stresses the importance of increasing prosperity by finding opportunities even under difficult, cross-border conditions

Industrial policy for competitiveness in the energy transition
Green intersections: the global embedding of climate change in policy, 53-74.

Green objectives have reshaped public policy worldwide since the signing in 2015 of the Paris Agreement to limit global warming. Climate policy has moved from being one policy among many to an objective embedded in public policies at every level, including energy, industrial, fiscal, trade, development and foreign policies. However, a clear outcome from this policy shift is yet to be seen, with emissions still rising and climate impacts intensifying. There is also backlash against greening in a charged geopolitical environment.
Nevertheless, the chapters in this volume, written by a range of experts worldwide, show that in many countries and policy areas, green objectives are still driving fundamental changes and many lessons have been learned. The goals of reducing emissions and enhancing economic and societal resilience to climate change will persist as climate impacts become more evident, and as the green transition produces successes at city, regional and national levels. In this context, this Bruegel Blueprint offers a fresh intellectual framework for understanding how the green transition is shaping cross-sectoral impacts across the globe.

Green Growth Opportunities for Hermosillo: Supplying the Global Energy Transition

As the world decarbonizes, demand for products which enable the green transition will increase rapidly. Solar panels and wind turbines will be needed to generate renewable energy, and critical minerals like copper and lithium will be required for wiring and batteries. Many other products and services within supply chains for such “green products” have a similar dynamic but are less widely known. While reducing carbon emissions often comes in conflict with economic development goals, producing the products that enable the world to decarbonize presents a significant opportunity for places to diversify their economies and generate income for their citizens.
This section analyzes Hermosillo’s opportunities to produce green products. We analyze the industries which produce these green products and Hermosillo’s capabilities in those industries in the most granular detail that data currently allows. We find not only that Hermosillo can produce products needed for the green transition and thus capture new sources of income for its people and businesses, but also that many of these products are good stepping stones for future economic activities. In the process of learning how to produce these products, Hermosillo can better enable further diversification opportunities. We classify these opportunities accordingly, along both the intensive margin –– industries in which Hermosillo already has a revealed comparative advantage –– and the extensive margin, in which it does not.
The most immediate green opportunity for Hermosillo lies in the mining of metals. Critical minerals required for the green transition, such as lithium and copper, are present in Sonora, but recent federal policy changes threaten expansion and productivity. The Government of Sonora needs to leverage its experience dealing with mining interests, environmental issues, and the demands of local communities to help co-produce mining policies which are both sustainable and productive. These can have positive spillovers in Hermosillo in the form of mining services growth and the location of mining company headquarters in the city, as in the past.
Overall, Hermosillo has opportunities to leverage the green transition to help diversify its economy, but is not as well positioned as peers. Hermosillo will need to coordinate investment efforts in order to compete with peer cities, who are better positioned to take advantage of these opportunities today. Industries such as manufacturing of electronic components and semiconductors and manufacturing of plastics products are among the more feasible and attractive industries for Hermosillo to target for promotion. Coordinating the manufacturing of green inputs with efforts to take advantage of solar energy resources is a strong strategy for the city. Large solar parks will need to be constructed to harness the cities’ solar energy resources. By using the planned build-out of these industries as a source of final demand, Hermosillo may be able to out-compete peer cities in attracting a solar panel OEM, which would help diversify the city into electronic components and semiconductors, as well as into the manufacturing of electric generation equipment.
