Clean Energy Finance and Investment Roadmap of the Philippines
In recent years, the Philippines has increased its commitment to climate action and its efforts to decarbonise the domestic economy. The power sector in the Philippines accounts for 58% of the country’s overall carbon emissions and will be an important driver of domestic emission reduction efforts to meet national climate and energy targets. Renewables, such as offshore wind, are expected to play a key role in the transition toward a low-carbon energy mix. With more than 17 thousand kilometres of coastline, the Philippines is estimated to have an offshore wind potential of 178 GW. However, this potential has yet to be leveraged. Alongside a changing power sector, progress on energy efficiency is needed to achieve the country’s emission reduction goals, with energy savings estimated at approximately 2% annually for the residential and commercial sectors. To deliver a clean energy transition, the Philippines requires estimated cumulative investments of over USD 300 billion between now and 2040. This report outlines key actions needed to unlock finance and investment in offshore wind power and energy efficiency in public buildings. It also provides a comprehensive overview of the progress to date and the challenges to mobilise near-term finance in those sectors, assist the Philippines transition towards a low-carbon economy, and achieve broader development goals.

Paper
Rethinking education in the context of climate change
State-of-the-art scientific evidence shows that our planet is approaching several environmental and climate tipping points faster than previously expected. This means that the international community is facing a rapidly closing window of opportunity to achieve profound transformations across sectors, systems and mindsets to secure a sustainable and liveable future. What is the role of education system in enabling social change at the massive scale and pace needed for climate change mitigation? And what policy levers can they employ to build resilience and adapt to environmental challenges? This paper explores ways to rethink educational approaches in the context of climate change, focussing primarily on school education, while exploring links to other levels of education. It looks specifically at strategies to restructure foundational science education and cross-curricular learning, zooms in on the potential of place-based approaches in empowering learners for action, and concludes by identifying policy levers to increase education system resilience.

Fostering Catastrophe Bond Markets in Asia and the Pacific
As climate change increases exposure to natural disasters, countries need new solutions to mitigate risks of natural hazards. For many in Asia and the Pacific, mobilising existing resources is not enough: they need to consider a grand design of disaster risk financing strategies. Catastrophe bonds (CAT bonds) can be an effective, market-based financing tool for the region. While the global CAT bond market has grown steadily since the 1990s, it remains weakly developed in Asia and the Pacific. Its successful development there requires robust purpose-built legal frameworks; developed general bond markets, especially in local currency; appropriate capacity building; and data-driven pricing models. This report explores each of these conditions along with policy suggestions for fostering them, and discusses the development of multi-country CAT bonds in Asia and the Pacific.

Mainstreaming Biodiversity into Renewable Power Infrastructure
As countries scale up climate action, they face the challenge of expanding renewable power while tackling biodiversity loss. Transitioning away from fossil fuels can reduce climate-related pressure on biodiversity, but brings its own risks. Unless carefully managed, the expansion of renewable power could compromise biodiversity. This report synthesises evidence on biodiversity impacts from renewable power infrastructure, with a focus on solar power, wind power and power lines. It identifies opportunities for mainstreaming biodiversity into power sector planning and policy to deliver better outcomes for nature and the climate. Drawing on good practice insights from across the globe, the report offers governments recommendations to align renewable power expansion with biodiversity goals.

Paper
Ukrainians and climate policies: What are Ukrainians’ preferences for using carbon revenues?
The paper presents the understanding of and attitudes towards climate change and climate policies in Ukraine, using a survey on a representative sample of more than 1 500 Ukrainians. The survey was carried out between October 2021 and February 2022 and presents the situation before Russia’s large-scale invasion of Ukraine. The survey tests support for three main climate policies in detail: a green infrastructure programme, a carbon tax with cash transfers and a ban on combustion-engine cars. It shows that support for climate policies depends on three key factors: how people perceive the effectiveness of the policies in reducing emissions, how they perceive distributional impacts on lower-income households (inequality concerns), and if they think their household will gain or lose from the policy. The survey also shows that when citizens receive information that specifically addresses these concerns, they exhibit stronger support for the policy. How the policy is designed also matters: Ukrainians widely accept a carbon tax when its revenues finance green investments and/or compensate lower-income households. The paper highlights seven considerations for Ukraine policymakers to design measures that are effective and supported by citizens. Following Russia’s war of aggression and once conditions are right, Ukrainian policymakers can also use the survey results to guide the reform of the environmental tax system- one of the goals in Ukraine’s recovery and reform agenda. The survey in Ukraine that the paper describes was conducted as part of a large-scale OECD international survey of attitudes toward climate policies carried out on over 40 000 respondents in twenty countries.

Paper
Review of energy subsidies in the context of energy sector reforms in Ukraine
This study evaluates the progress of fossil-fuel subsidy reform in Ukraine since its launch in 2016 using the OECD “bottom-up”, inventory, approach. It also identifies major subsidy schemes that need significant reform. The report reflects the energy subsidy policies and reforms in Ukraine prior to Russia’s full-scale invasion in February 2022. The analysis covers: budgetary transfers, government revenue foregone (or tax expenditure), induced transfers in the form of cross-subsidies or below market tariffs and transfer of risk to government. The study also covers fossil-fuels subsidies to production and consumption, particularly, for natural gas, coal and electricity generated from fossil fuels while support for energy efficiency and renewables is considered for comparative purposes. This report also briefly discusses the taxation and energy pricing policies in Ukraine that have had direct or indirect impact on the evolution of fossil-fuel subsidies in the country. Detailed estimates of all individual support measures are provided in the Annexes to the report.

Financing Uzbekistan’s Green Transition
The scale of Uzbekistan’s green transition requires a marked increase in private financing to fill the existing spending gap. The outsized role of the state in Uzbekistan’s economy and its underdeveloped domestic capital market act as significant constraints and call for a diversification of sources to finance the green transition. Since 2021, Uzbekistan has made green bonds a central part of its strategy to fill the financing gap and mobilise new sources of capital for its domestic green infrastructure projects. This publication explores the current market and institutional set-up in Uzbekistan, the reforms that have led to recent issuances of both sovereign and corporate thematic bonds, and the remaining barriers to further uptake of the instrument. The report also provides policy recommendations related to the market's institutional set up, Uzbekistan's regulatory framework for debt capital markets and emerging opportunities for further green bond use aimed at key stakeholders, including policy makers and market participants.

A Territorial Approach to Climate Action and Resilience
Global warming is likely to reach 1.5°C as early as in 2030, with current climate action falling short of meeting the Paris Agreement goals and a mounting risk of tipping beyond the ability of human societies to adapt. Building on broader OECD work on climate, this report proposes a new OECD territorial climate indicator framework and demonstrates that the potential to mitigate greenhouse gas emissions, adapt to climate impacts and address vulnerabilities varies across different territories. The report also presents a policy framework of 9 recommended actions to help decision makers unleash more effective climate action and resilience, both by integrating a territorial approach into national and subnational climate policies and by mainstreaming climate objectives into urban, rural and regional policies. The report summarises the analysis into a checklist for national and local governments to implement a territorial approach to climate and resilience policies, as well as a compendium of 36 best practices from cities, regions and countries from all around the world.

Assessing net-zero metrics for financial institutions
Financial markets need clear information and credible metrics to inform climate-related investment and financing decisions. This report explores key challenges and opportunities related to the transparency, specificity and integrity of metrics to support the monitoring of financial institutions’ net-zero commitments. It provides an assessment of metrics put forward in five voluntary frameworks, identifies the type of information and metrics proposed, their common themes and gaps, as well as limitations in underlying methodological guidance that may hinder financial institutions’ ability to report and disclose metrics. The report highlights a need both for continued efforts to develop robust metrics and incentivise improved data disclosure, as well as for international co-operation to reduce fragmentation and provide further transparency on the scope of metrics and underlying methodologies.

Climate adaptation: Why local governments cannot do it alone
Given the direct impacts of climate change are felt first and foremost at the local level, many have called for climate adaptation to be a local responsibility. Indeed, local authorities have a major influence on climate change adaptation - such as through their land use and permitting decisions. Yet, their actions are strongly determined by the national fiscal, regulatory and policy contexts in which they are embedded in. This policy paper provides an overview and a discussion of the roles and responsibilities for climate adaptation across levels of government. It argues that co-operation across levels of government is needed to strengthen adaptation at the local level. This policy paper was prepared as part of the OECD Territorial Approach to Climate Action and Resilience programme, which supports subnational authorities in their efforts to accelerate the net zero transition and build systemic resilience.

OECD Inventory of Support Measures for Fossil Fuels 2023
Despite commitments to scale up and speed up climate action, the fiscal cost of government support for fossil fuels almost doubled in 2022 to reach more than USD 1.4 trillion as governments across the OECD and partner countries introduced substantial initiatives to mitigate high energy costs on households and firms, caused in part by Russia's war of aggression against Ukraine. This rising trend is a real threat to our collective net zero goals and highlights the challenges of staying on track with net zero commitments in the face of geopolitical and economic disruption. Going forward, it will be critical that support measures are reformed to better target those most in need. Support for fossil fuels should also be phased out as soon as possible. This will help free up much needed resources for the transition towards net zero emissions and accelerate innovation to improve energy efficiency.

Financing solutions to foster industrial decarbonisation in emerging and developing economies
Industry decarbonisation is a cornerstone to reach net-zero emissions by this mid-century. The diversity of industrial activities, processes and products, the complexity of global industrial value chains, and the international competition make industry decarbonisation a challenging objective. Annual investments in low-carbon technologies for industry decarbonisation need to increase by a factor of three to five by 2030 compared to current levels to align industrial emissions with net-zero pathways. This paper analyses available financing solutions to scale up investments at pace, especially in emerging and developing economies where industrial production is growing rapidly whilst available finance is limited. It highlights de-risking and financial instruments and models that can help accelerate investments and draws lessons from twelve financing industry decarbonisation case studies which demonstrate how private capital can be mobilised.
