Sustainable development and climate change are two pressing and interconnected issues that countries have committed to address at the international level. The 2030 Agenda for Sustainable Development, with the 17 Sustainable Development Goals (SDGs) including climate action, at its core was adopted by the United Nations (UN) in 2015. The same year, the Paris Agreement was adopted by Parties of the UN Framework Convention on Climate Change. Both instruments have clear global and national targets in the medium- and long-term that are still far from being met.


Progress towards SDGs and climate objectives is hindered by the same crucial challenge—the sheer size of the funding gap. Significant investments are needed to achieve the SDGs and climate goals. Yet experts agree that current financial flows towards these objectives are hugely inadequate. The financing gap to achieve the 2030 Agenda, which increased by 56 percent following the COVID-19 outbreak, reached US$3.9 trillion in 2020. And when it comes to achieving climate objectives, only about 16 percent of the estimated US$3.8 trillion needed annually through 2025 are currently being met. Additionally, international adaptation financial flows to developing countries are five to ten times below estimated needs, and the gap is widening, with annual adaptation needs estimated at US$160-340 billion by 2030 and US$315-565 billion by 2050. If nothing is done, the situation is expected to worsen in the current challenging macroeconomic conditions.


The implications of this funding gap are compounded by the fact that costs are unevenly borne by countries. Climate change impacts are disproportionately borne by developing countries, particularly least developed countries and small island developing states (SIDS) . These countries are already paying for losses and damages due to climate disasters, estimated at over US$500 billion between 2000-2019 for the 55 most vulnerable countries. With increasing climate impacts, needs for adaptation finance are expected to exceed 1 percent of GDP in low-income and developing economies, and up to 20 percent of GDP for SIDS. Failure to halt climate change will, thus, negatively affect the achievement of the SDGs for developing countries, while failure to advance on other SDGs will increase their vulnerability to climate impacts and exacerbate the climate crisis.


Risks of a disjointed approach to climate and SDG finance

The SDGs and climate are interrelated, yet they have been tackled in a disjointed manner for too long, prompting competition for financial resources. While the SDG framework promotes an integrated approach, the focus of financial flows has been on one SDG at a time, and mostly on ‘bankable’ activities. This is also the case across climate objectives, with over 90 percent of climate finance going to mitigation, despite growing needs and an increasing gap in adaptation finance. And although the commitment of developed countries was to provide ‘new and additional’ finance for developing countries to tackle climate change, only 6 percent of climate finance provided from 2011 to 2018 is considered as new and additional to official development assistance. Filling the climate finance gap cannot continue to come at the expense of the SDGs, or vice versa.


Continuing with this disjointed approach threatens the achievement of the SDGs and climate objectives, increasing the risk of negative side-effects and jeopardising potential co-benefits across objectives. For instance, industrialisation projects targeted by SDG-9 may lead to technological lock-in that may be harmful to climate objectives, as in the case of building industrial plants reliant on fossil gas instead of using renewable and clean energy sources. Similarly, actions to adapt to climate change may have detrimental impacts on efforts to reduce inequality (SDG-10) if adapted infrastructure is only built in wealthy areas. In contrast, massive investments in renewable energy can lead to improved energy access and a reduction of energy poverty, thereby contributing to building sustainable territories (SDG-11), increasing opportunities for economic growth (SDG-8), and reducing inequalities. Considering these risks and opportunities, leaving the silo perspective behind by moving towards an integrated approach in the way SDGs and climate are financed is a necessary step forward.


Towards an integrated approach

Recent initiatives bring sustainable development and climate objectives together at the policy level; these are a good starting point but do not provide a comprehensive perspective on funding and financing needs.



Beyond the policy level, just energy transition partnerships (JETPs) are an important step to leave the silo approach to project financing, but still miss the mark given their sectoral focus. Initiated in 2021, JETPs are a funding model designed to support the phase out of fossil fuels in developing and emerging economies while tackling the social consequences of the transition, notably addressing issues such as job losses in highly emitting sectors. JETPs typically lay out priority investment requirements and match them with funding in various forms. Pioneered in South Africa and followed by Indonesia and Vietnam, JETPs recently expanded to Senegal and are expected for other countries such as India. Yet the scope of JETPs does not allow for a comprehensive overview of the amounts and types of financing needed for the achievement of climate and sustainable development objectives.


Developing a national financing plan for the transition to achieve climate and development targets will help countries channel financial resources where most are needed rather than where it is easiest (for instance, investments in sustainable agriculture versus in renewables). A financing plan for the transition will point at financing needs and public policies to achieve objectives. It will also point at investment needs from private entities and levers to trigger them, and will indicate how much funding is needed from international lenders. A financing plan can be developed based on green budgeting initiatives or integrated national financing frameworks, and will benefit from being complemented by other tools such as climate finance landscapes or economic modelling including climate risks.


Role of international financial institutions in synergising climate and SDG finance

But countries cannot make it on their own. Synergising climate and SDG finance will require efforts from international financial institutions (IFIs). The broad development mandate of IFIs and local public development banks and the required additionality of their intervention (i.e., only funding projects that are either too risky or not profitable enough to attract private finance) make them key players in synergising SDG and climate finance. Their contribution to countries, through financial or non-financial support (such as capacity building, tools development), should be demand-driven, with a long-term perspective, and based both on national development and climate priorities maximising opportunities for co-benefits, ideally following national financing plans. Additionally, IFIs and public development banks should systematically strive for real economy impacts and deflect from projects with limited potential for change.


Ongoing discussions on the reform of the international financial architecture are the perfect opportunity to move towards an integrated approach for climate and SDG finance. International efforts in several forums can foster the required changes to advance in this direction. The Summit for a New Global Financial Pact, held in Paris in June 2023, was the opportunity to stress the need “to address joint nature, climate, and development challenges through increased global cooperation”. Upcoming international agenda milestones, such as the Finance in Common Summit, the G20 Summit, the UN SDG Summit, the International Monetary Fund and World Bank annual meetings, and COP28 need to keep up the momentum and propose real-economy, technical solutions to ensure (i) that countries are equipped with a long-term integrated view on their climate and development needs, and (ii) that development institutions offer relevant, long-term, and demand-driven support to countries.

    Approaches to meeting the Paris Agreement goals: options for Public Development Banks

    Options for Public Development Banks. Since the adoption of the Paris Agreement in 2015, several public development banks (PDBs) have responded with structured approaches to align their operations with the Agreement’s expectations (as described in Section 1). However, many PDBs, particularly those in emerging markets and developing economies, are yet to adopt an approach to align with the Paris Agreement (i.e., Paris alignment). As entities whose investment mandates are established by the Parties to the Paris Agreement (i.e., national governments), PDBs have specific obligations derived directly from these Parties’ commitments to act across all policy and regulatory frameworks under their jurisdictions, including for state-owned or state-mandated institutions and agencies. Accordingly, PDBs are expected to operate in a manner that supports the achievement of the Paris goals. More specifically, they are obligated to integrate their activities within the Agreement’s implementation mechanism by providing financial, technical, and capacity building support that is entirely consistent with national low-emission climate-resilient development pathways.

    World bank and IMF Spring Meetings: How can the reformed institutions play a leading role in funding the transition?

    Rethinking how development can be financed to take into account the rising challenges of our time is a fastidious task, especially when thousands of experts, decision makers and practitioners want to leave their print. The outline of the new international financial architecture is being debated again this week, with more questions open for discussion than consensus on the answers.

    More and better finance: maximising positive climate impacts for a timely transition 

    Since the Paris Agreement in 2015, significant strides have been made to foster the commitment of countries and financial institutions to address the climate crisis and ensure that climate risks and opportunities are considered in investments. However, with emissions required to peak before 2025, our window of opportunity is rapidly closing to keep +1.5°C within reach. Financial needs to lower greenhouse gas (GHG) emissions and to address adaptation priorities are increasing rapidly in the meantime. Luis Zamarioli Santos and Diana Cárdenas Monar, from I4CE, believe that commitment must urgently translate into action, and action must bring the urgent change the world needs. Both governments and public financial institutions have a central role to play to deliver more and better finance, maximising positive impacts. This blogpost highlights some opportunities to advance in the path for a systemic transformation, involving key stakeholders with a whole-economy approach.
