From Climate Plans to Climate Action: Resilient Sri Lanka

World Environment Day

Environment needs urgent action

Consultations held for developing the National Adaptation Plan

• For Sri Lanka, this moment comes at a critical juncture. The country has made significant progress in identifying climate risks and setting adaptation priorities
• Together, these plans represent an important milestone in Sri Lanka’s climate journey

As the world marks World Environment Day on 5 June under the global call to act #NowForClimate, the focus is no longer only on understanding the impact of climate change, but on accelerating the practical actions needed to respond to them. 

For Sri Lanka, this moment comes at a critical juncture. The country has made significant progress in identifying climate risks and setting adaptation priorities. The challenge now is to translate those plans into investments and implementation that strengthen resilience for communities, businesses and ecosystems across the country.

Sri Lanka is already experiencing the impacts of a changing climate. More frequent floods, prolonged droughts, coastal erosion, landslides and changing weather patterns are affecting livelihoods, infrastructure, agriculture, water resources and public health. These impacts are expected to intensify in the coming years, making climate resilience an increasingly important national development priority. For a country pursuing economic recovery and long-term development, climate resilience is therefore not a separate environmental concern, but a foundation for protecting livelihoods, public assets, food and water security, and future investment.

Recognising these challenges, the Government of Sri Lanka has been advancing a comprehensive climate adaptation agenda. With support from the Green Climate Fund, and with the Global Green Growth Institute (GGGI), a treaty-based, international intergovernmental organisation, serving as delivery partner to the Ministry of Environment, Sri Lanka has prepared the forthcoming National Adaptation Plan for Climate Change Impacts in Sri Lanka 2026–2035. 

Nationally owned framework

Submitted for Cabinet approval, the NAP provides a nationally owned framework to guide adaptation across 13 vulnerable sectors, identifying climate risks, priority actions and estimated investment needs of USD 1.03 billion, equivalent to approximately LKR 331 billion. While this may seem like a steep number, the cost of not taking action is often higher -- in December 2025, the World Bank estimated that Cyclone Ditwah caused USD 4.1 billion in direct physical damage, about 4 percent of Sri Lanka’s GDP. 

The national adaptation framework is complemented by Provincial Adaptation Plans for all nine provinces, which translate national priorities into locally relevant actions that respond to provincial development realities, climate vulnerabilities and investment needs.

Together, these plans represent an important milestone in Sri Lanka’s climate journey. They provide a clear roadmap for strengthening resilience through the established institutional architecture, while helping to align adaptation efforts with broader development objectives.

The updated NAP also recognises that effective adaptation planning must look beyond administrative boundaries. While Provincial Adaptation Plans provide an important sub-national planning framework, climate risks often follow natural systems such as river basins, catchments and ecological regions. By identifying natural boundaries as complementary planning units, the NAP supports a more integrated approach to addressing floods, droughts, water scarcity, landslides, coastal erosion and ecosystem degradation across districts and provinces.

However, plans alone do not build resilience.

The next phase of Sri Lanka’s climate journey must therefore focus on implementation: mobilising finance, strengthening institutions, preparing investment-ready projects and building partnerships that can deliver adaptation priorities at scale.

Climate finance

This is where climate finance becomes increasingly important.

Over the past decade, international climate finance has become a major source of support for developing countries seeking to strengthen resilience and pursue low-carbon development pathways. Yet accessing and deploying climate finance effectively remains a challenge for many countries. Building investment-ready project proposals, strengthening institutional coordination, engaging financial institutions and creating enabling environments for private sector participation are all critical elements of a successful climate finance ecosystem.

To help address these challenges, the Government of Sri Lanka, with support from GGGI, is launching a new initiative titled Mobilising International and Domestic Climate Finance and Private Investments for Climate Resilience in Sri Lanka.

Funded through the Green Climate Fund’s Readiness window, the initiative represents an important next step in supporting implementation of Sri Lanka’s climate priorities. Its objective is to strengthen the country’s capacity to mobilise long-term climate finance for low-carbon and climate-resilient development, while supporting implementation of Sri Lanka’s Nationally Determined Contributions under the Paris Agreement, and the forthcoming national and provincial adaptation plans. 

The Climate Change Secretariat, in its role as Sri Lanka’s National Designated Authority to the Green Climate Fund, will provide strategic leadership in working with national ministries, provincial councils, district and divisional administrations, local authorities, financial institutions and other key stakeholders. The initiative will also help create enabling conditions for greater private sector participation through environmental and social management system guidelines, sustainable banking frameworks and green bond development. Together, these efforts aim to translate climate priorities into investment-ready opportunities and mobilise greater financing for climate-resilient development.

Importantly, the initiative is not solely about capacity building. The USD 1 million GCF Readiness grant is expected to help unlock more than USD 40 million in green investments, including through future green or sustainability bond issuances. This demonstrates how targeted public and concessional resources can play a catalytic role: strengthening systems, reducing barriers and helping attract much larger flows of private and institutional capital towards climate-resilient development.

The initiative also complements broader efforts to expand sustainable finance opportunities in Sri Lanka. GGGI is currently exploring opportunities to support Sri Lanka under the European Commission-supported Global Green Bond Initiative, a EUR 5 million programme aligned with the European Union’s Global Gateway agenda.

The Global Green Bond Initiative supports governments, cities and financial institutions in developing green and sustainability bond issuances through technical assistance covering investment pipeline development, framework preparation, investor engagement and post-issuance reporting. For Sri Lanka, such support could help strengthen the country’s sustainable finance ecosystem while creating new pathways to mobilise capital for climate and development priorities.

Together, these efforts reflect a broader shift in how climate action is being approached. Climate resilience is no longer solely an environmental issue. It is increasingly an investment, economic, social and development priority that requires collaboration between governments, financial institutions, businesses, development partners and communities.

Moving to climate action

As Sri Lanka moves from climate planning to climate action, the priority must be to ensure that the country’s adaptation plans do not remain on paper, but become investable, implementable and measurable actions that protect people, ecosystems and the economy.

On this World Environment Day, the message is clear: building resilience must now be financed, implemented and delivered.
