Global CO2 Emissions - Dataset for top 25 countries

The CO2-wide dataset provides carbon dioxide emissions data for the top 25 emitting countries from 1975 to 2021, measured in thousand metric tons. The dataset, sourced from UN Data, captures long-term trends in global emissions, helping researchers and policymakers analyze the impact of industrialization, economic growth, and environmental policies. Using this data, we created interactive bar charts and treemaps with D3.js, enabling dynamic visualizations that highlight emission patterns over time. These visual tools offer a clear, engaging way to explore how emissions have evolved across countries, supporting climate research, awareness, and data-driven decision-making. The dataset is available for further analysis and can be embedded into other platforms for broader accessibility.
