Strategic Partnership Deepens Responsible Investment Capabilities
The fund development represents a deepening of the long-standing partnership between Aon and Irish Life Investment Managers (ILIM), Ireland’s leading asset management firm with over €100 billion in assets under management. ILIM, one of the first Irish companies to sign up to the United Nations Principles for Responsible Investing, collaborated closely with Aon in designing and developing the solution to meet the specific needs of Aon’s institutional clients.
According to Denis Lyons, Head of Investment at Aon Ireland, responsible investing has transitioned from a niche consideration to a mainstream investment priority, with the market experiencing strong growth in recent years. Despite global economic volatility, investors increasingly seek opportunities to make positive planetary and societal impact while achieving sustainable long-term financial returns.
Brian Morrissey, Head of European Partnerships at ILIM, emphasized that the firm’s flexible partnership approach enables close collaboration with both local and international partners, leveraging responsible investment and fund management expertise to deliver tailored solutions that align with each client’s specific objectives. This bespoke development process reflects growing sophistication in sustainable finance markets, where one-size-fits-all approaches are giving way to customized strategies that address unique client requirements and regional considerations.
Investment Strategy Targets Low-Carbon Transition in Developing Economies
The Aon Emerging Markets Climate Transition Fund focuses on companies and stocks across developing markets that demonstrate commitment to climate action and alignment with specific UN Sustainable Development Goals. The fund’s investment strategy employs environmental data to systematically reduce portfolio carbon emissions over time, with the objective of aligning with global targets to limit warming to 1.5 degrees Celsius and achieve net zero carbon dioxide emissions by 2050.
The fund provides what Aon and ILIM describe as a modern alternative to traditional passive emerging market equity investments, incorporating enhanced sustainability factors throughout the investment process while maintaining the diversification and growth potential associated with emerging market exposure. This approach addresses investor demand for products that capture the economic dynamism of developing economies while simultaneously supporting climate transition imperatives.
ILIM’s investment approach combines proprietary quantitative modeling with enhanced sustainability factors to deliver a flexible, low tracking error methodology suited to the complexities of emerging markets. This technical framework enables the fund to navigate the unique challenges of developing economy investing—including data availability limitations, regulatory variations, and market liquidity constraints—while maintaining robust environmental, social, and governance integration.
The strategy employs both positive and negative screens, applying systematic tilts compared to broad emerging market indices toward companies demonstrating climate-related progress and away from those lagging in decarbonization efforts. This rules-based investment approach seeks to mitigate climate-related financial risks while positioning portfolios to benefit from the global transition to low-carbon economic systems.
Comprehensive Exclusion Criteria Ensure Values Alignment
The fund implements rigorous exclusion criteria to ensure alignment with investor values and international norms. The strategy excludes companies involved in controversial weapons production, tobacco manufacturing, and thermal coal mining—sectors increasingly recognized as inconsistent with sustainable investment principles. Additionally, the fund screens out companies that violate the UN Global Compact, the world’s largest corporate sustainability initiative comprising ten principles covering human rights, labor standards, environmental protection, and anti-corruption measures.
These exclusions reflect evolving investor expectations regarding corporate conduct and environmental impact. Controversial weapons—including cluster munitions, anti-personnel mines, and chemical or biological weapons—are excluded based on humanitarian concerns and international treaty obligations. Tobacco production exclusion addresses both public health considerations and regulatory risk, as governments worldwide implement stricter tobacco control measures.
The thermal coal mining exclusion addresses one of the most carbon-intensive fossil fuel sectors, recognizing that achieving climate targets requires systematic transition away from coal-based energy systems. This exclusion aligns with the fund’s overarching objective to support low-carbon transition while acknowledging that coal mining faces mounting regulatory pressures, stranded asset risks, and declining economic competitiveness relative to renewable energy alternatives.
The UN Global Compact violation screen provides a comprehensive ethical framework spanning multiple dimensions of corporate responsibility. Companies that demonstrate patterns of serious human rights abuses, labor rights violations, environmental damage, or corrupt practices are excluded regardless of their financial performance, ensuring that sustainability considerations extend beyond narrowly defined environmental metrics to encompass broader stakeholder impacts.
Milestone Achievement Reflects Growing Climate Investment Scale
The €260 million fund launch represents more than an isolated product introduction—it marks Aon Ireland’s crossing of the €1 billion threshold in climate transition strategy assets. This milestone follows the successful introduction of Aon’s initial Developed Markets Climate Transition Fund in 2024, demonstrating sustained institutional appetite for climate-focused investment solutions across both developed and developing market contexts.
The scale achievement reflects broader trends in global sustainable finance markets, which have experienced remarkable growth despite periodic volatility. According to industry data, sustainable fund assets reached new highs in recent years, driven by regulatory developments, institutional investor commitments, and growing recognition that climate-related risks and opportunities represent material financial considerations rather than peripheral ethical preferences.
Aon’s climate transition platform now provides institutional investors with comprehensive geographic exposure spanning both developed and emerging markets, enabling portfolio construction that captures climate transition opportunities across the full spectrum of global economic development stages. This geographic diversity is particularly valuable given that emerging markets contribute over 80% of global energy demand growth, with much of that demand increasingly being met by renewable energy sources rather than fossil fuels.
The billion-euro milestone also positions Aon as a significant player in Ireland’s sustainable finance ecosystem, contributing to the country’s efforts to establish itself as a European hub for responsible investment. Ireland’s sustainable finance market has experienced accelerating growth, supported by strong asset management capabilities, favorable regulatory frameworks, and institutional investor interest in products that address climate risk while delivering competitive financial returns.
Emerging Markets Present Unique Climate Transition Opportunities
The specific focus on emerging markets reflects recognition that developing economies represent both the greatest challenges and the most significant opportunities in global climate transition. These nations account for nearly 90% of global population and over 40% of global economic output, while experiencing disproportionate impacts from climate change including extreme weather events, agricultural disruption, and water scarcity.
Simultaneously, emerging markets are undergoing rapid urbanization, industrial growth, and rising energy needs, creating critical junctures where infrastructure and energy system decisions will shape emissions trajectories for decades. Investment capital deployed today into clean energy, sustainable transportation, efficient buildings, and climate-resilient infrastructure in these economies can generate outsized impact relative to comparable investments in mature markets with established infrastructure bases.
According to recent analyses, climate finance in emerging markets surpassed USD 1 trillion in 2023, with approximately 80% mobilized domestically rather than through international flows. This data point underscores both the scale of capital deployment already occurring and the potential for international investment products like Aon’s fund to complement and catalyze domestic climate finance mobilization.
The investment opportunity set in emerging markets spans multiple sectors and technologies. Renewable energy deployment—particularly solar and wind generation—is accelerating rapidly across developing economies, often achieving cost competitiveness with fossil alternatives without subsidy support. Electric vehicle adoption is growing in major markets like China, India, and parts of Southeast Asia, creating investment opportunities across manufacturing, charging infrastructure, and battery supply chains.
Sustainable agriculture, water management, climate adaptation infrastructure, and circular economy solutions represent additional investment themes where emerging markets face pressing challenges that innovative companies and technologies are positioning to address. The Aon fund’s focus on companies contributing to resource scarcity solutions and healthy ecosystems directly targets these opportunity areas.

Integration with Broader UN Sustainable Development Framework
Beyond climate-specific metrics, the fund’s investment strategy explicitly references contribution to UN Sustainable Development Goals beyond SDG 13 (Climate Action), including objectives related to resource scarcity, health, ecosystems, and basic social needs. This multi-dimensional framework recognizes that climate transition cannot be pursued in isolation from other development imperatives, particularly in emerging market contexts where poverty reduction, health improvement, and infrastructure development remain urgent priorities.
The interconnections between climate action and other sustainable development objectives create both synergies and potential trade-offs that investment strategies must navigate. For example, renewable energy deployment (contributing to SDG 7 on clean energy and SDG 13 on climate action) can also advance SDG 3 (health) by reducing air pollution from fossil fuel combustion, while potentially creating tensions with SDG 15 (life on land) if solar or wind projects impact sensitive ecosystems.
Similarly, climate adaptation infrastructure investments—such as flood protection systems, drought-resistant water supply, or climate-resilient transportation networks—directly support SDG 11 (sustainable cities and communities) and SDG 9 (industry, innovation, and infrastructure) while contributing to climate resilience objectives. Agricultural investments that enhance productivity while reducing emissions and improving farmer livelihoods can simultaneously advance SDG 2 (zero hunger), SDG 8 (decent work and economic growth), and climate goals.
The fund’s framework for assessing SDG alignment likely draws on emerging methodologies for mapping corporate activities and revenues to specific sustainable development objectives. These approaches typically involve sector-level analysis to identify which business activities contribute positively, neutrally, or negatively to each goal, combined with company-specific assessment of operational practices, product portfolios, and strategic commitments.
Broader Context: Aon’s Climate Risk and Sustainability Initiatives
The Emerging Markets Climate Transition Fund launch represents one component of Aon’s broader climate and sustainability strategy. The company has developed extensive climate risk advisory capabilities, helping institutional investors, public sector entities, and firms with large real estate holdings make better decisions about climate-related financial risks through specialized data, modeling, and expertise.
Aon’s physical risk modeling tools—built on the company’s natural catastrophe and risk engineering expertise—assess exposure of client assets to climate change impacts. The firm’s actuarial and analytics capabilities enable quantification of value at risk under various warming scenarios and evaluation of portfolio vulnerabilities to develop tailored mitigation strategies. This technical infrastructure positions Aon to support clients in understanding both transition risks (arising from policy changes, technological shifts, and market preferences as economies decarbonize) and physical risks (resulting from acute and chronic climate change impacts).
The company’s Climate and Catastrophe Insight reports document escalating economic costs from natural disasters. In 2025, direct economic costs from physical impacts of natural disasters totaled $380 billion—22% above the 21st century average—with only 31% of these losses covered by insurance. The Los Angeles wildfires alone caused $41 billion in insured losses, marking the costliest wildfire events in global history.
These loss trends underscore why institutional investors increasingly recognize climate risk as a material financial consideration rather than merely a reputational or ethical concern. Physical climate risks threaten asset values, operational continuity, and supply chain resilience across virtually all sectors and geographies. Transition risks—including policy changes like carbon pricing, technological disruption favoring low-carbon alternatives, and shifting consumer preferences—create both threats to incumbent business models and opportunities for companies positioning for a low-carbon economy.
Growing Institutional Demand Drives Sustainable Finance Market Evolution
The launch occurs amid evolving dynamics in global sustainable finance markets. While sustainable fund assets have reached record levels exceeding $3.9 trillion as of mid-2025, flows have experienced volatility reflecting regional policy differences, product refinement, and investor search for credible impact alongside financial returns. Europe and Asia ex-Japan have seen capital inflows while North America has experienced outflows, reflecting differing regulatory environments and market maturity levels.
Product-level trends show transition finance gaining prominence as investors recognize that achieving climate goals requires supporting companies in carbon-intensive sectors that commit to credible decarbonization pathways rather than simply excluding all high-emitting activities. The International Capital Market Association’s Climate Transition Bond Guidelines and Loan Market Association’s Guide to Transition Loans—both published in late 2025—established frameworks for credibly labeled transition finance products.
This evolution from exclusion-focused approaches toward transition-inclusive strategies reflects pragmatic recognition that global decarbonization requires transforming existing economic systems rather than merely avoiding certain sectors. Companies operating in industries like steel, cement, chemicals, aviation, and shipping face technical challenges in eliminating emissions but are developing innovative solutions including hydrogen fuel alternatives, carbon capture technologies, and process efficiency improvements. Investment capital supporting these transitions—when backed by robust governance and accountability mechanisms—can accelerate economywide decarbonization.
The emphasis on credible measurement and reporting frameworks addresses legitimate concerns about greenwashing in sustainable finance markets. Investors and regulators increasingly demand standardized metrics, third-party verification, transparent reporting, and accountability mechanisms to ensure that sustainability-labeled products deliver genuine environmental and social benefits rather than merely repackaging conventional investments with marketing adjustments.
Irish Market Context and Regulatory Environment
The fund’s launch in Ireland occurs against the backdrop of the country’s efforts to meet legally binding emissions reduction targets. Ireland committed to halving greenhouse gas emissions by 2030—an ambitious target that recent data suggests may be challenging to achieve under current policy trajectories. The government’s Climate Action Plan, which outlines specific sectoral measures to achieve these reductions, has faced delays despite mounting urgency as the 2030 deadline approaches.
This national context creates both challenges and opportunities for sustainable finance initiatives. On one hand, the gap between Ireland’s emissions reduction commitments and actual progress underscores the scale of transformation required across energy systems, transportation infrastructure, building stocks, agricultural practices, and industrial processes. This transformation will require substantial capital investment, creating opportunities for financial products that channel resources toward climate solutions.
On the other hand, policy uncertainty or implementation delays could affect the economic attractiveness of certain climate investments if regulatory incentives, carbon pricing mechanisms, or renewable energy support schemes fail to materialize as anticipated. Sophisticated investors therefore assess not only the intrinsic economics of climate solutions but also the policy frameworks and political commitment that shape market conditions for low-carbon technologies and practices.
Ireland’s position as a European financial services hub—hosting the European operations of numerous global asset managers, insurance companies, and financial institutions—provides strategic advantages for sustainable finance product development and distribution. The country’s regulatory framework aligns with European Union directives including the Sustainable Finance Disclosure Regulation (SFDR), which establishes classification and disclosure requirements for sustainable investment products, and the EU Taxonomy for Sustainable Activities, which provides science-based criteria for determining which economic activities make substantial contributions to environmental objectives.
Technical Investment Approach and Portfolio Construction
While specific details of the fund’s portfolio construction methodology remain proprietary, the general approach described by Aon and ILIM suggests a systematic, quantitatively-driven strategy that integrates sustainability factors throughout the investment process. This methodology likely begins with defining the investable universe across emerging market equities, applying exclusion screens to remove companies involved in prohibited activities or violating ethical standards.
From this filtered universe, the strategy then applies enhanced sustainability analysis incorporating multiple data sources and metrics. Climate-related factors might include carbon intensity of operations, renewable energy usage, climate risk management practices, emissions reduction targets and progress, climate-related capital expenditures, and strategic positioning relative to low-carbon transition. Broader ESG considerations could encompass corporate governance quality, labor practices, human rights policies, environmental management systems, and stakeholder engagement approaches.
The quantitative modeling framework then constructs portfolios that optimize across multiple objectives: tracking error relative to broad emerging market benchmarks, sector and country exposure constraints, liquidity requirements, and sustainability characteristic targets including carbon emission intensity reductions. This multi-factor optimization approach seeks to deliver sustainability improvements while managing unintended bets or concentration risks that could increase volatility or deviation from client expectations regarding emerging market exposure.
Active ownership components likely include proxy voting aligned with sustainability principles and engagement with portfolio companies on material ESG issues. ILIM’s established active ownership program focuses on core ESG themes including decarbonization and stakeholder-centric business models, employing both voting power and direct engagement to promote better corporate practices on issues like climate change, human rights, natural capital management, and corporate governance.
Forward-Looking Implications and Market Positioning
The €260 million fund launch and €1 billion climate transition asset milestone position Aon competitively in the evolving sustainable finance landscape. As institutional investors—including pension funds, insurance companies, sovereign wealth funds, and endowments—face increasing pressure from beneficiaries, regulators, and stakeholders to address climate-related risks and align portfolios with net zero commitments, demand for sophisticated climate transition investment solutions continues growing.
The dual-fund structure spanning both developed and emerging markets provides comprehensive geographic coverage enabling investors to construct globally diversified climate transition portfolios. This approach addresses different aspects of global decarbonization: developed markets often focus on technological innovation, policy frameworks, and systematic transformation of established infrastructure, while emerging markets present opportunities to influence development trajectories by supporting clean infrastructure deployment at scale during critical growth phases.
Looking forward, several trends seem likely to shape evolution of products like Aon’s climate transition funds. Regulatory requirements for climate-related financial disclosures will continue strengthening, with frameworks like the International Sustainability Standards Board’s IFRS S1 and S2 standards establishing baseline expectations for corporate sustainability reporting. These disclosure improvements should enhance data availability and quality, enabling more sophisticated investment analysis and portfolio construction.
Technological developments in areas like renewable energy costs, battery storage, green hydrogen production, carbon capture and storage, and clean manufacturing processes will affect the risk-return profiles of climate transition investments. Breakthroughs that accelerate cost reductions or performance improvements can make certain investment themes more economically attractive, while setbacks or slower-than-anticipated progress could dampen returns in specific sectors or technologies.
Policy evolution across both developed and emerging markets will significantly influence climate investment opportunities. Carbon pricing mechanisms, renewable energy mandates, vehicle electrification requirements, building efficiency standards, and industrial decarbonization support programs all affect relative economics of climate solutions versus carbon-intensive alternatives. International cooperation on climate finance, technology transfer, and capacity building will shape opportunities in developing economies specifically.
Conclusion: Strategic Positioning in Growing Market
Aon’s launch of the €260 million Emerging Markets Climate Transition Fund, bringing total climate transition strategy assets past €1 billion, reflects the professional services firm’s strategic positioning in the accelerating institutional demand for credible climate-focused investment products. The partnership with Irish Life Investment Managers leverages established responsible investment expertise to deliver solutions aligned with both UN Sustainable Development Goals and institutional investor requirements for professionally managed emerging market exposure.
The fund addresses the distinctive opportunity set that emerging markets present in global climate transition—economies contributing majority shares of energy demand growth and facing urgent development imperatives while simultaneously making critical infrastructure and energy system decisions that will shape emissions trajectories for decades. By providing investors with systematic access to companies supporting low-carbon transition in developing economies, the fund channels capital toward regions where investment impact on global decarbonization may be most significant.
Denis Lyons’s observation that responsible investing has shifted from niche to mainstream captures a fundamental transformation in how institutional investors conceptualize fiduciary duty, risk management, and long-term value creation. Climate-related financial risks—both physical impacts from changing weather patterns and transition risks from economywide decarbonization—are increasingly recognized as material considerations affecting asset values, operational resilience, and strategic positioning across virtually all sectors and geographies.
The comprehensive exclusion criteria, UN SDG alignment framework, and integration with Aon’s broader climate risk advisory capabilities position the fund to meet sophisticated institutional investor requirements for products that deliver both competitive financial returns and credible sustainability impact. As global sustainable finance markets continue maturing through enhanced disclosure standards, refined methodologies, and growing scale, Aon’s billion-euro climate transition platform represents meaningful strategic presence in what appears likely to remain a growth segment of institutional asset management for years to come.
