Abstract:
The slow pace of decarbonisation of buildings and transportation threatens the European Union’s goal of reducing emissions by 55 percent by 2030 and achieving net zero by 2050. To address this, a new emissions trading system, ETS2, is being introduced to put a carbon price on fuels used in buildings and road transport. However, the resulting cost increases risk a disproportionate impact on vulnerable households and small and medium sized enterprises. The European Union has created the Social Climate Fund (SCF) to address these distributional challenges. This instrument redistributes a portion of auction revenues generated by the ETS2 among EU countries, in order to protect the most vulnerable. A much larger share of ETS2 revenues will flow directly to national governments, offering significant opportunities for social measures and investments in the green transition. The use of those revenues will dictate how successful EU countries are in managing the transition and protecting households, particularly in higher-income member states, which will receive relatively smaller shares of SCF funding. ETS2 is an essential part of the EU climate policy toolkit. Governments should employ good practices, as identified by the European Commission, to tackle emissions from buildings and transport and to gradually phase out income support, in line with the achievement of investment targets and milestones. Higher-income EU countries should develop additional targeted financing levers to protect the vulnerable and to introduce extra enablers to encourage private investment. Proper sequencing, outreach and communication will be essential to ensure the uptake of measures and public support for policy instruments. Cross-country learning should be leveraged, including through the creation of a European policy registry that will help countries compare their approaches and potentially amend their SCF spending plans on the basis of learning from policies that been successful elsewhere.

Abstract:
Three quarters of the European Union’s greenhouse gas emissions stem from burning coal, oil and natural gas to produce energy services, including heating for buildings, transportation and operation of machinery. The transition to climate neutrality means these services must be provided without associated emissions. It is not possible today to determine tomorrow’s optimal clean energy system, largely because the cost, limitations and capability developments of competing technologies cannot be predicted. Energy systems with widely diverging shares of ‘green fuels’, in the form of electricity, hydrogen and synthetic hydrocarbons, remain conceivable. We find the overall cost of these systems to be of the same order of magnitude, but they involve larger investments at different stages of value chains. A large share of synthetic hydrocarbons would require more investment outside the EU, but less in domestic infrastructure and demand-side appliances, while electrification requires large investment in domestic infrastructure and appliances. Current projections show an overall cost advantage for direct electrification, but projections will evolve and critical players may push hard for alternative fuels. Policy will thus play a major role in shaping this balance. Political decisions should, first, push out carbon-emitting technology, primarily through carbon pricing. The more credible and predictable this strategy is over the coming decades, the smoother will be both divestment from brown technologies and investment in green technologies. Second, policy needs to help ensure that enough climate-neutral alternatives are available in time. Clear public support should be given to three system decisions about which we are sufficiently confident: the massive roll-out of renewable electricity generation; the electrification of significant shares of final energy consumption; and rapid phase-out of coal from electricity generation. For energy services where no dominant system has yet emerged, policy should forcefully explore different solutions by supporting technological and regulatory experimentation. Given the size and urgency of the transition, the current knowledge infrastructure in Europe is insufficient. Data on the current and projected state of the energy system remains inconsistent, either published in different places or not at all. This impedes the societal discussion. The transition to climate neutrality in Europe and elsewhere will be unnecessarily expensive without a knowledge infrastructure that allows society to learn which technologies, systems, and polices work best under which circumstances.

3. The role of competition in the transition to climate neutrality

Abstract:
The transition to climate neutrality requires the reallocation of production factors from polluting activities to non-polluting activities. The main push for this reallocation will come from governmental decarbonisation targets that are translated into stringent climate policy tools, such as carbon pricing and emissions standards. But the complex process of recombining production factors will require the coordination of millions of individuals and firms. The efficiency of this recombination process will be a main driver of the cost of the transition. Based on a consistent analytical framework, I argue that much more political attention should be paid to the markets and regulators that guide the re-allocation of production factors, to bring them in line with a carbon-neutral economy at the best service of European consumers. Three main issues should be considered: 1. The transition will change the role and efficiency of markets in allocating resources; 2. Competitive markets can make the transition more efficient; 3. In some areas, a too-narrow focus on competition can be detrimental, and needs to be discussed. To improve the institutions for resource allocation in the transition, policymakers should revisit three levels of intervention: 1) competition rules and enforcement should be adjusted to meet the new challenges of the transition; 2) efficient markets that are central to a climate-neutral economy – such as for electricity, emission rights or circular logistics – need to be properly designed; 3) the advantages and disadvantages of more direct state control in specific sectors should be revisited in light of the challenges of the transition. In summary, policymakers need to get away from simplistic state-or-market narratives. The focus should be on developing politically feasible frameworks for leveraging the benefits of competition for efficient resource allocation in the transition. Institutions should not focus solely on static efficiency, but must forcefully encourage investments in new systems and innovation. The role of institutions that determine resource allocation in the transition is an underappreciated but crucial area for future research and policy action.

Abstract:
Many of the technologies that can help the European Union become a net-zero emissions economy by 2050 have been shown to work but are not yet commercially competitive with incumbent fossil-fuel technologies. There is not enough private investment to drive the deployment of new low-carbon alternatives. This is primarily because carbon prices are neither high enough nor stable. There are a number of benefits from the deployment of low-carbon technologies that private firms do not factor in. These include the benefits of decreasing industry-wide costs over time, and the global climate benefits from the development of low-carbon technologies within the EU that can subsequently be exported. The result is an investment level below the socially optimal value in the EU. Commercialisation contracts could be implemented as a temporary measure to remove the risk associated with uncertain carbon prices for ambitious low-carbon projects. The aim of the contracts would be to increase private investment to the socially optimal level. Contracts would be allocated through auctions in which fixed prices for abated emissions over a fixed duration would be agreed on a project-by-project basis. On an annual basis, public subsidies amounting to the difference between the agreed carbon price and the actual EU carbon price would be provided to investors, depending on the total carbon emissions abated. As long as EU carbon prices are low, investors would receive larger subsidies to ensure their competitiveness. Contracts would be auctioned at EU level. This would generate increased competition compared to national auctions, leading to more efficient outcomes and preventing fragmentation of the single market. From about €3 billion to €6 billion would be provided to the main industrial emitting sectors annually, with the amount reducing as the EU carbon price rises and low-carbon technologies become competitive without subsidy.

5. Navigating through hydrogen

Abstract:
Hydrogen is seen as a means to decarbonise sectors with greenhouse gas emissions that are hard to reduce, as a medium for energy storage, and as a fallback in case halted fossil-fuel imports lead to energy shortages. Hydrogen is likely to play at least some role in the European Union’s achievement by 2050 of a net-zero greenhouse gas emissions target. However, production of hydrogen in the EU is currently emissions intensive. Hydrogen supply could be decarbonised if produced via electrolysis based on electricity from renewable sources, or produced from natural gas with carbon, capture, and storage. The theoretical production potential of low-carbon hydrogen is virtually unlimited and production volumes will thus depend only on demand and supply cost. Estimates of final hydrogen demand in 2050 range from levels similar to today’s in a low-demand scenario, to ten times today’s level in a high-demand scenario. Hydrogen is used as either a chemical feedstock or an energy source. A base level of 2050 demand can be derived from looking at sectors that already consume hydrogen and others that are likely to adopt hydrogen. The use of hydrogen in many sectors has been demonstrated. Whether use will increase depends on the complex interplay between competing energy supplies, public policy, technological and systems innovation, and consumer preferences. Policymakers must address the need to displace carbon-intensive hydrogen with low-carbon hydrogen, and incentivise the uptake of hydrogen as a means to decarbonise sectors with hard-to-reduce emissions. Certain key principles can be followed without regret: driving down supply costs of low-carbon hydrogen production; accelerating initial deployment with public support to test the economic viability and enable learning; and continued strengthening of climate policies such as the EU emissions trading system to stimulate the growth of hydrogen-based solutions in the areas for which hydrogen is most suitable.

Abstract:
Putting carbon pricing at the centre of the EU climate policy architecture would provide major benefits. Obtaining these benefits requires a uniform, credible and durable carbon price – the economic first-best solution, however, several preconditions required to attain this solution are not yet met. This paper proposes a sequenced approach to ensure convergence of the policy mix on the first-best in the long run.
