Malaysia’s First Biennial Transparency Report (BTR1) shows that carbon dioxide (CO₂) is the main contribution greenhouse gas (GHG), making up 242.12 Tg CO₂ eq. (93.24%) of the total. The energy industries show the highest emissions with about 149.32 Tg CO₂ equivalent, which include public electricity and heat production, petroleum refining, manufacture of solid fuels, and other energy industries as the largest contributors, followed by the transport and manufacturing sectors.

The pie chart shows that methane (CH₄) and nitrous oxide (N₂O) contribute to the total emission at 6.34% and 0.42%. Overall, the energy sector shows that energy production and fuel use remain the main sources of Malaysia’s greenhouse gas emissions.

This dataset is extracted from the Table SIC3.2 of the Malaysia’s First Biennial Transparency Report (BTR1) (see documentation). This data will show much each sub-sector, such as like energy industries, transport, and manufacturing contributes to emissions and compare different types of greenhouse gases emission (CO₂, CH₄, and N₂O).

To explore this dashboard, click on each gas button in the center to filter the visuals and see emissions related to that gas. The top-left panel shows the horizontal bar chart with total GHG emissions by sub-sectors. Users can see which industries emit the most gases. The top-right panel is a pie chart showing the percentage share of each gas in total emissions. The bottom-left panel shows the horizontal bar chart to see which gases dominate in each sub-sector. This compares all gases (CO₂, CH₄, N₂O) side-by-side across different sub-sectors. The bottom-right shows the total emissions by sub-sector in emission values (in Gg CO₂ equivalent). The total emissions for all sectors amount to 259.67 Tg CO₂ eq.
