The water sector – contributing to the implementation of Grenada’s NDCs

Like all small island states in the Caribbean region, Grenada faces the risk of water scarcity, exacerbated by climate change, and has high potential for the introduction of renewable energy and energy efficiency. The government has identified the resilience of the water sector as a priority in all national climate strategy documents and successfully submitted a large-scale project to the Green Climate Fund (GCF), which in its compontents 1-3 aims to improve the resilience of the water sector. The components 4 and 5 of this GCF project are co-funded through this IKI Project, which is developing the first carbon-neutral water utility in the Caribbean and disseminating this approach in the region. In this context, it is advising the Grenada National Water and Sanitation Authority to improve its water and energy efficiency. To this end, it promotes the introduction of renewable energy and supports the implementation of the water loss reduction strategy.

State of implementation/results

Integration of the water sector into NAP and NDC:
- In December 2025, Grenada’s National Adaptation Plan (NAP) was adopted by the Cabinet. The NAP serves as a framework for monitoring and evaluation in line with national adaptation priorities. Overall, 30 consultations were held between 2023 and 2025 with 200 representatives from the public and governmental institutions. The NAP continues to identify the water sector as a high adaptation priority, based on the findings generated through the project.
- The consultations on national climate policy under the leadership of the National Climate Change Committee have been completed, and the final document has been prepared. These discussions raise awareness of climate resilience and enable the government to engage directly with communities.
- A draft NDC implementation plan was shared with stakeholders.
- In August 2023, the first national greenhouse gas report for the water sector in Grenada was completed.
Renewable energies in the water sector:
- In March 2023, negotiations began with the regulatory authority and the electricity utility on a CO₂ reduction strategy for the national water authority NAWASA.
- In August 2024, the planning for three (Celeste, Dusty Highway, Central) solar photovoltaic plants was completed, and in 2025 the tendering process was successfully finalized.
Energy efficiency in the water sector:
- Through improved data management practices and more systematic water balance accounting, NAWASA established a Non-Revenue Water (NRW) department, which began its work in September 2024. This department equipped numerous metering zones with new devices and repaired leaks.
Foundation for replication of the approach in the Caribbean:
- The Regional Exchange Platform “Regional Climate and Water Resource Community” has 75 members from the Caribbean and promotes knowledge exchange by inviting associated members, including through webinars on gender and water loss control.
- The G-CREWS project presents two to three case studies from the project each year at the conference of the Caribbean Water and Wastewater Association.
- The G-CREWS Water Ambassadors Program (GWAP) received significant recognition at the 13th Comprehensive Disaster Management Conference in Nevis.
- In March 2025, G-CREWS organized a forum on water technologies as part of the regional Nationally Determined Contributions Finance Initiative (NDCFI) conference. The event focused on water-efficient technologies and approaches.
- The project organized a study tour for participants from the region who are currently preparing project proposals for climate-resilient water projects to be financed by the Green Climate Fund (GCF). Participants from Saint Kitts and Nevis, Saint Lucia, Grenada, and the Organization of Eastern Caribbean States (OECS) exchanged experiences on infrastructure, project management, and public outreach strategies.
Knowledge Management and Awareness Raising:
- In October 2025, the project attended the CWWA conference and presented the conference paper “Social Media Involvement in Driving Community Change”. It also participated in the CAWASA Water Operators Conference.
- In May 2024, a delegation from the national water authority visited the IFAT trade fair for water, wastewater, waste management, and raw materials to identify technical solutions for existing challenges in Grenada’s water sector.
- The project supported the Government of Grenada in launching the first knowledge management portal for climate resilience in Grenada and provided training for ministry staff on maintaining the website.
- Through cooperation with the Global Water Partnership-Caribbean (GWP-C), G-CREWS is strengthening regional cooperation in climate-resilient water resources management.
