"Decarbonisation is the reduction of carbon dioxide emissions using low carbon power sources, lowering output of greenhouse gasses into the atmosphere. This is essential to meet global temperature standards set by international climate agreements. To limit global warming to 1.5°C, hence avoiding the worst-case scenarios predicted by climate science, the world economy must rapidly reduce its emissions and reach climate neutrality within the next three decades. This will not be an easy journey. Shifting away from carbon-intensive production will require a historic transformation of the structure of our economies. Written by a team of academics linked to the European think tank Bruegel, The Macroeconomics of Decarbonisation provides a guide to the macroeconomic fundamentals of decarbonisation. It identifies the major economic transformations, both over the long- and short-run, and the roadblocks requiring policy intervention. It proposes a macroeconomic policy agenda for decarbonisation to achieve the climate goals of the international community."

"Decarbonisation and digitalisation are reshaping the European energy system, which will become more decentralised and interconnected with other sectors. Cities have the opportunity to be the key drivers of decarbonisation, but this will require the implementation of a new bottom-up governance system. This paper outlines a four-step mechanism in order to achieve decarbonisation at city level.oing local: empowering cities to lead EU decarbonisation"

"Even in the early days of COVID-19, the European Union signalled its commitment to make its post-pandemic recovery green. The disruption caused by the pandemic would require significant rebuilding of the economy, offering an opportunity to accelerate green investment in the context of the European Green Deal. But pursuing a green recovery is not as straightforward as it might seem. Complex trade-offs must be negotiated between the need for short-term stimulus and the need to address the long-term challenge posed by global warming.

To support policymakers in this difficult endeavour, Bruegel launched in 2020 the Bruegel Green Recovery Group, an initiative supported by the European Climate Foundation. Its aim was to be a platform for dialogue between high-level EU policymakers and academics on green recovery, in Europe and beyond. This Blueprint compiles some of the work of prominent voices of the Group, on issues that will touch the lives of all Europeans."

"In 2022, overall European Union industrial employment and output increased above 2021 levels, despite rocketing energy prices. However, output declined from energy-intensive industries including basic metals, chemicals, non-metallic minerals and paper, for which energy costs represent a much bigger share of production costs than for less energy-intensive manufacturing. Energy prices are likely to remain above historic levels for the foreseeable future.

In its industrial strategy response to this context, the EU must ask first whether the energy-intensive parts of the value chain should be outsourced permanently. Conditional on the answer being no, the second question is how to reduce energy prices to ensure the competitiveness of the energy-intensive productions stages that remain in the EU.

First, the EU could bridge the high energy price period with unconditional subsidies, which seems to be the preferred strategy currently. This will avoid irreversible large-scale relocation abroad but is expensive, does not help to drive down energy prices and poses risks of fragmentation within the EU. It will only succeed if internationally competitive energy supplies are made available quickly.

Second, the EU could support decarbonised production processes built on large-scale deployment of domestic renewables, grid interconnectors and storage. This would accelerate the green transition and reduce clean-tech prices worldwide. However, EU taxpayers would bear the cost of new technologies, without any guarantee of solving the current cost-competitiveness issue.

Third, the EU could facilitate imports of energy-intensive products, while helping EU industry move to higher value-added parts of the value chain. Subsidies could be given directly to industrial sectors that have not become structurally uncompetitive, while bringing down energy demand and thus energy prices. However, this strategy would result in temporarily higher unemployment and factory closures in energy-intensive industries, would need to accommodate concerns over excessive reliance on imports and would need to be engineered to address carbon leakage.

Policymakers should implement a mix of these policies. The EU should subsidise existing energy-intensive industries only in clearly justified cases, while deciding which energy-intensive products can be left to international market forces. By choosing which decarbonisation investments should be supported in Europe, the EU can combine industrial competitiveness and environmental sustainability."

"Low-carbon energy technologies are pivotal for decarbonising our economies up to 2050 while ensuring secure and affordable energy. Consequently, innovation that reduces the cost of low-carbon energy would play an important role in reducing transition costs. We assess the two most prominent innovation policy instruments (i) public research, development and demonstration (RD&D) subsidies and (ii) public deployment policies.

Our results indicate that both deployment and RD&D coincide with increasing knowledge generation and the improved competitiveness of renewable energy technologies. We find that both support schemes together have a greater effect that they would individually, that RD&D support is unsurprisingly more effective in driving patents and that timing matters. Current wind deployment based on past wind RD&D spending coincides best with wind patenting. If we look into competitiveness we find a similar picture, with the greatest effect coming from deployment.

Finally, we find significant cross-border effects, especially for winddeployment. Increased deployment in one country coincides with increased patenting in nearby countries.

Based on our findings we argue that both deployment and RD&D support are needed to create innovation in renewable energy technologies. However, we worry that current support is unbalanced. Public spending on deployment has been two orders of magnitude larger (in 2010 about €48 billion in the five largest EU countries in 2010) than spending on RD&D support (about €315 million). Consequently, basing the policy mix more on empirical evidence could increase the efficiency of innovation policy targeted towards renewable energy technologies."

"Cognisant of the many facets of climate change, this report looks through the lens of economics, that is, the social science that measures the economic impact of climate change and the costs and benefits of trying to mitigate it and adapt to it.

From an investment perspective, issues for study include the balance between investment in mitigating greenhouse-gas emissions and adaptation to climate change; the urgency and timing of investing in both; obstacles to investment; and policies to remove them and make investment profitable. From a growth perspective, issues of interest include the link between climate action and economic growth; the short-term and the long-term dimensions of this link; and the importance of innovation as an interface between climate action and economic growth.

One of the key messages from this report is that there is unexploited scope for making Europe's climate action more efficient, growth-friendly, and in tune with fiscal constraints."

"The euro-area crisis dominates the economic news. Yet, the world and Europe may face even more important challenges that will shape our lives and the lives of our children.World population is projected to increase to 9 billion or more by 2050. At the same time, current trends indicate an increase in living standards and a growing middle class around the world. These two mega-trends will have profound implications, and the way they are managed will be one of the key determinants of prosperity and peace in the decades or even centuries to come. A number of factors are important in this respect.
More people and more income will increase the global demand for energy. Choosing the right sources of this energy will be one of the determining factors of global temperature.
The continued reliance on fossil-fuel energy sources is one of the main factors behind the risk of significant global temperature increases. The internationally agreed goal of limiting the temperature rise to less than two degrees Celsius above pre-industrial levels appears increasingly illusory. Currently, fossil energy sources dominate many economic areas. For instance, our transport infrastructure is largely based on fossil fuels, and is thereby one of the main contributor of the carbon dioxide emissions that are linked to global temperature. Thinking about a decarbonisation strategy is therefore a key challenge with a global dimension.
Economic growth in Europe will be affected by the costs of this transition from the current energy and transport system. A smooth transition towards a low-carbon energy and transport system could come at comparatively modest cost. Furthermore, identifying the most economically beneficial solutions early on and becoming a global technology leader and standard setter offers vast opportunities for exports and economic growth. Hence, our decarbonisation strategy may eventually have a greater impact on long-term European growth than the current economic crisis.
Bruegel is contributing to this debate with this report, which is based on research that received funding from the Fuel Cell and Hydrogen Joint Undertaking. The authors argue carefully that to make decarbonisation growth friendly, a consistent policy approach is needed. Policy intervention appears indispensable as the energy and transport system is so based around and locked-in into an incumbent technology. Overcoming this lock-in is crucial. The report makes three main proposals. First, the scope, geographical coverage and duration of carbon pricing should be extended.
By setting a higher carbon price, incentives for developing and investing in new low-carbon technologies are created. Second, temporary consortia for new infrastructure to solve early-phase market failures could be put in place. This is discussed using the example of hydrogen vehicles. Lastly and importantly, an open and public transition model is needed so that second-best transport solutions do not get a head start that afterwards cannot be reversed."
