The ‘Intergovernmental Panel on Climate Change (IPCC)’ laid the scientific groundwork for the widespread agreement that, in the medium and long terms, development and inclusive growth are seriously threatened by climate change caused by humans. The importance of sustainable development and the pressing need to address climate change cannot be underscored in the rapidly evolving global setting. A key tool for reaching carbon neutrality and greening sustainable economic growth is ‘Climate Finance’, which is centered on eco-friendly investments and activities. By supporting renewable energy sources like solar and wind power, climate finance assists nations in lowering their greenhouse gas emissions. It also aids in community adaptation to the effects of climate change. Combining human capital and emerging technologies such as blockchain, Artificial Intelligence (AI) with climate finance is an additional opportunity to boost migration prospects and ease transitions in adaptation processes. Furthermore, in addition to addressing concerns about the potentially negative effects of some climate policies on development prospects and economic growth, an integrated policy package incorporating the scaling up of low-carbon and climate-resilient infrastructure, sustainable finance, and carbon pricing could also help achieve the goals of the ‘UN Sustainable Development Goals (SDGs) and the Paris Agreement’. In order to solve urgent environmental issues and achieve sustainable development goals, climate finance must improve. This chapter explores the need of climate finance and human capital with evolving technologies. Further, it analyzes the synergy of climate finance with climate neutrality and challenges and barriers in the achievement of sustainability. Furthermore, a need for a regulatory framework for achieving climate neutrality in terms of climate finance is discussed.
