Working across the thematic priorities of sustainable energy, green cities, sustainable landscapes, and water and sanitation, GGGI aims to deliver reduced GHG emissions, creation of green jobs, access to sustainable services, improved air quality, adequate supply of ecosystem services, and enhanced adaptation to climate change. GGGI projects strengthen green growth frameworks, support green bankable projects, increase green investment flows, and improve knowledge sharing and learning between countries. GGGI has developed a value chain approach to our interventions, offering services that range from green growth diagnosis, policy planning, project development and finance to ensure that countries have correctly identified the highest impact green growth interventions, have the policy and strategy structure in place to address them, and that they are able to design and finance projects. This is done through demand-driven and bespoke technical advisory services, knowledge sharing & capacity development, and private sector solutions for pro-poor green growth interventions and through leveraging our partnerships with providers of climate finance and development assistance as well as knowledge networks. GGGI works closely with our partner governments, serving as a neutral, trusted advisor and providing services based on government request. This is facilitated in large part by being embedded in partner ministries, allowing GGGI to consult widely with government, jointly plan, design, and implement programs, involve all the key stakeholders and decision-makers, and build capacity long-term. BACKGROUND: Project Background Feasibility Study for Ground Mounted Solar in Vakabuli The iTaukei Trust Fund Board (TTFB) was established by an Act of Parliament, the iTaukei Trust Fund Act (2004) to promote the cultural, economic, and social advancement of Fijis indigenous iTaukei people. TTFB supports programs that focus on cultural preservation, education, sustainable development, and leadership training, ensuring that the iTaukei community thrives in a rapidly changing world. TTFBs goals are to provide funding for programs that promote Fijian language, culture, and the study of ethno-history and ethno-geography; to support the development of management, leadership, and entrepreneurial skills among indigenous Fijians and Rotumans; and to sponsor research that deepens understanding and preserves the languages, art, and cultural heritage of indigenous Fijians and Rotumans. In support of these aims TTFBs investments encompass a diverse portfolio. TTFB aims to ensure consistent returns over the years, reinforcing its commitment to sustainable growth. Fiji Pine Group The Fiji Pine Group is a majority Government of Fiji owned entity initially established by the Government of Fiji in an effort to generate economic activities in the rural areas as well as to fully utilise talasiga (dry grasslands) on which Caribbean pine (Pinus caribaea var. hondurensis) was planted. Since 2013 Fiji Pine has been FSC certified, a global certification standard that monitors, measures and evaluates the forestry industry to ensure that it is operating sustainably. As part of its Strategic Plan 2025 2029 Fiji Pine group aims to overcome the challenges of climate threats, market volatility and operational demands to leverage over 80,000 hectares of land at eight pine stations in Fiji. In line with the actions set out with in Fijis Low Emissions Development Strategy and Fijis ambitions to transition towards a higher proportion of renewable energy within its energy mix.
