Abstract

Climate change, driven by human-induced greenhouse gas emissions, poses a critical threat to the planet, prompting countries worldwide to pledge carbon neutrality by the mid-century. This literature review identifies and analyzes strategies and technologies for achieving carbon neutrality across various sectors and regions. The study aims to determine the research focus across sectors, highlighting the well-studied sectors while identifying critical gaps in other sectors, offering policymakers and researchers a clearer understanding of which sectors need more attention and investment to achieve carbon neutrality goals. Through employing a systematic literature review approach, PRISMA 2020, 113 articles published between 2019 and 2023 were analyzed using content and bibliometric analysis. The results of the content analysis show that the energy sector is the most extensively studied, with a focus on the integration of renewable energy sources, energy efficiency, and carbon capture technologies. Furthermore, results showed promising developments in energy-efficient electrification methods, and circular economy principles can be seen in the building, transportation, and industrial sectors. On the other hand, while having a large potential for sequestering carbon, the agriculture and forestry sectors are still understudied. As for the bibliometric analysis, this study reveals the complex interplay between technological innovation, sectoral strategies, and policy intervention in achieving carbon neutrality. It highlights the need for integrated, interdisciplinary approaches that consider interactions between technological, economic, social, and environmental factors. The analysis also emphasizes the importance of lifecycle assessment, economic complexity, and investments in shaping effective carbon neutrality strategies. As such, future research should address the identified gaps, particularly in agriculture and forestry, and develop more comprehensive models for the transition to carbon neutrality that incorporate both technological solutions and broader socio-economic considerations.
