Policies to mitigate climate change require a fundamental change to taxation in the transport sector. The shift to electric vehicles and continuing improvements in the fuel efficiency of internal combustion engine vehicles will extinguish revenues from fuel taxes. This report assesses the options for reforming vehicle and road-use taxes. It identifies potential packages of taxes and charges that could generate revenue more efficiently and maintain and enhance incentives for the transition to a sustainable transport system.

Coastal shipping – maritime transport that takes place between ports on the same continent – represents around half of the global shipping market. It is also crucial to the connectivity of island regions and regional development. Decarbonising coastal shipping presents both challenges and opportunities, as does the growing concentration of ownership in the maritime transport sector. This report outlines the most pressing challenges the coastal shipping sector currently faces and provides governments and policy makers with concrete actions to help address them.

Accounting for nearly 40% of global energy-related CO2 emissions and sometimes as much as 70% in large cities, buildings and construction are central to the low-carbon transition. Decarbonising buildings, especially the old stock, through energy efficiency improvements and renewable energy use, not only reduces carbon emissions, but also generates co-benefits in health, energy affordability and the labour market. Additionally, global mega-trends and the transition to a green recovery from COVID-19 provide impetus for stakeholders to take action. Cities and regions have a key role to play and can leverage prerogatives in regulation, public procurement and stakeholder engagement, while addressing multiple governance, capacity and funding gaps. To accelerate and scale up their action, cities and regions need to work with national governments to create an effective governance mechanism. Drawing on the findings of a dedicated survey of cities and regions of all sizes from both OECD and non-OECD countries, this report explains their significant role, explores sub-national policy measures, identifies key obstacles, and provides policy recommendations and a checklist for both national and subnational governments to drive the decarbonisation of buildings in cities and regions.

The report presents an in-depth analysis of various policies that aim to reduce the greenhouse gas emissions of urban transport. Decarbonising transport lies at the core of efforts to mitigate climate change and has close links to urban sustainability and housing affordability. The report identifies the drivers of rising emissions in the urban transport sector and offers pathways to reduce them through a combination of transport and land use policies. The analysis yields a holistic welfare evaluation of these policies, assessing them according to their environmental effectiveness, their economic efficiency and their impact on fiscal balance and housing affordability. The report concludes that significant reductions in emissions from urban transport can be achieved through a careful alignment of transport policies designed to promote the use of public transit and electric vehicles, and land use policies, which foster a more compact urban form. The study is based on the case of Auckland, New Zealand but the lessons drawn are relevant for institutions and governments working on issues relating to urban sustainability, transport, housing and climate change mitigation.

This publication sheds light on the issue of decentralisation in Mexico. It shows that decentralisation can make decision-making more efficient and increase local participation in development issues. Decentralisation can provide a better framework to improve local infrastructure and to channel the necessary finance from public and private sources. The modernisation of infrastructure systems in Mexico's cities and regions would improve the quality of life and stimulate economic development, thus fostering entrepreneurship and employment. The initiatives being launched in Mexico in this direction constitute a major change of the country, one better adapted to the opportunities of the global economy and to the country's increasingly pluralistic system. Over time, Mexico will make better use of its own natural and human resources, reducing inequality and broadening opportunity throughout its territory.

This review examines the reforms undertaken by the government of Kazakhstan in the area of public governance and evaluates their impact on the powers and responsibilities of subnational levels of government. It places particular emphasis on finding the right allocation of roles and responsibilities among different levels of government, and on using decentralisation as a means to increase self-reliance, civic participation, accountability, and enhanced capacity at the local level. The report also offers a number of recommendations for further strengthening the role of local executive bodies and democratising some aspects of local government.

Bulgaria has made solid progress in its territorial governance and socio-economic development. Yet, it has not been able to counteract large and increasing territorial disparities. Doing so will require addressing remaining structural challenges that may be limiting further transformation, government performance and regional resilience. It will also depend on shifting from a centrally-designed approach to regional development policy to one that incorporates subnational input and carefully considers regional specificities. Such a shift, coupled with a revitalised multi-level governance model to strengthen regional and municipal governance, could generate more balanced regional development and inclusive growth in Bulgaria. This multi-level governance study considers the avenues Bulgarian national and subnational authorities could take to ensure more place-based regional development and governance. It emphasises a comprehensive, yet incremental, approach to decentralisation and regionalisation reforms to generate more effective and balanced regional development.

This report has been prepared by the OECD upon request by the Portuguese Independent Commission for Decentralisation. Decentralisation and regionalisation reforms have recently emerged on the Portugal’s policy agenda, with two main objectives: assigning more tasks to municipalities and strengthening regional level governance. The report presents a diagnosis of Portugal multi-level governance in international perspectives and highlights the strengths and challenges of the system. It then presents three potential policy paths of regional reform for Portugal. As the options are not mutually exclusive, they could work as complements to each other. The report analyses the conditions under which the reforms may deliver more economic efficiency and regional equity.

Who finances educational facilities? What are the criteria used and how are they applied? Each country has its own system; however, the general trends are towards diversification of funding sources and decentralisation of responsibility. This publication examines the links between decentralisation and new means of financing. Although local control can guarantee greater effectiveness and responsiveness to local needs, central government remains responsible for ensuring access to equity and equality of educational opportunity. The greatest challenge in education funding consists of achieving compatibility between these objectives and technological development.

The decommissioning of nuclear power plants is a topic of increasing interest to governments and the industry as many nuclear units approach retirement. This report, based upon data provided by 26 countries and analysed by government and industry experts, covers a variety of reactor types and sizes. The findings on decommissioning cost elements and driving factors in their variance will be of interest to analysts and policy makers in the nuclear energy field.

This report reviews a wide range of congestion control measures. It analyses their effectiveness, financial and operational requirements, implementation time and public acceptability. It focuses on the role of technology in addressing congestion, including sensors, wireless systems, traffic light optimisation and trip planning data. The report takes an in‑depth look at the use of HOT lanes to control congestion, the different ways in which they can be used and their effectiveness relative to other initiatives. The report is based on discussions held during the September 2020 ITF Roundtable on Congestion Control Experience and Recommendations.

Transport activity continues to cause large adverse impacts on the environment, human health and the economy. But is a negative impact of transport on the environment a necessary consequence of economic growth? This book illustrates that decoupling the environmental impacts of transport from economic growth is achievable, through the efficient use of charges, fees, taxes and other economic instruments. These economic approaches can complement regulatory measures to encourage a shift towards more environmentally-friendly modes of transport, such as from road to certain forms of rail transport. Other factors which could help to decouple transport impacts from economic growth are improvements in freight transport logistics, and dematerialisation.

Acts of vandalism or violence and the defacing of facilities are increasing in public transport systems. This report provides an analysis of the social and psychological causes which is a prerequisite to formulate corrective measures. A comparison of what a number of systems have experienced focuses attention on the scale of the problems involved and different ways of resolving them. The recommendations that can be made differentiate between the responsibilities of the operators, national governments and the various local authorities.

As behavioural insights (BI) become more widely used, countries are looking to expand the application of the methodology to new frontiers of policy making. This report tests behaviourally informed solutions to complex policy problems in the fields of competition, consumer protection, energy consumption and safety through a variety of theoretical and experimental approaches. The results give policy makers new ideas for tackling policy problems related to individual behaviour, as well as for changing the behaviour of organisations.

In spite of progress made to date and the significant long-term ambition announced by many countries, climate policy actions remain insufficient to meet the Paris Agreement objectives. While several international initiatives aim to track and monitor climate policies, there is not yet a “go to” place for a comprehensive inventory of policy actions and best practices worldwide. Such a platform would also ideally serve to compare policies’ effectiveness reflecting the diversity of country circumstances. Progress in this direction would help to promote an ambitious but globally more coherent and better-coordinated approach to emission reductions through a broad range of policies. This report lays out a roadmap for data and analytical work to support this aim, with a view to enhancing global dialogue and building trust on issues spanning climate change mitigation policies and their macro-economic repercussions. Key elements to strengthen the assessment and comparison of countries’ climate change mitigation policies across countries include: broadening and deepening the stocktaking of mitigation policies; extending and agreeing on an operational methodology for estimating the impact of these policies on emissions and on potential metrics to compare them; and assessing the broader economic effects of different climate policies.

COVID-19 has put renewed focus on the importance of addressing longstanding challenges that OECD governments face in delivering public services, especially in regions with people spread over a wider area where economies of scale are more difficult to achieve. The physical infrastructure needed to provide good quality education and health services can be more complex and expensive in rural and remote regions that also struggle to attract and retain education and health care professionals. Acute ageing trends in many rural regions and, in some cases, a shrinking population will require sustainable policy responses that will need to be coherent with pressure to drive efficiencies in public spending. This report examines the nuances specific to the delivery of education and health care to people everywhere, offering recommendations on how to better adapt provision to the realities of today and the emerging realities of tomorrow to face the challenges of distance, demographic change and fiscal belt-tightening. The report also examines digital connectivity issues in rural and remote regions, recognising the significant scope for digital delivery of services to mitigate challenges related to distance. Finally, the report looks at governance issues, including fiscal issues, through which the delivery of these critical services is administered and paid for.
