Green Taxes as a Catalyst for Net-Zero Emissions: Policy Design, Implementation Challenges, and Global Opportunities for Climate Action

The worldwide recognition of achieving zero greenhouse gas emissions by 2050 faces a major deficiency because current policies fail to accomplish this objective. The world will face a temperature rise exceeding 2.5°C according to IPCC (2023) projections for the century’s end based on present climate action patterns. Green taxes present themselves as a strong yet unexploited instrument among fiscal tools that enables the implementation of systemic environmental change for carbon cost internalization. The adoption of green taxes faces structural implementation hurdles because they meet resistance from the government and cause social inequality problems and institutional barriers. This research investigates the implementation roads green taxation can use for realizing equitable effective net-zero transformations. The researchers used comparative case studies alongside descriptive statistics to conduct their analysis of green tax initiatives in Sweden with British Columbia and France and as well as South Africa and China. The research collected first-hand and secondary information from official documents together with carbon pricing databases as well as expert interviews and survey responses from the public. Emissions targets become attainable through correctly disbursed green taxes which preserve growth as long as societies adopt strong institutional frameworks and establish progressive social support programs. The implementation of poor public communication together with weak equity considerations in French policies leads to significant political obstacles.The research combines theoretical study with real-world policy development through its examination of economic difficulties and political matters and social aspects. Future research should study how green taxation affects the economy through time along with expanding its analysis across emerging economic nations. For the net-zero shift to move forward at an accelerated pace researchers have revealed that adaptive green tax policies should be just and have global coordination mechanisms.
