Since 1993 Bangladesh has steadily increased its total emissions, with an increase of over 30% since 2011 (excluding LULUCF). The energy sector is the single largest source of CO₂ emissions. Emissions from the agriculture and waste sectors were 39% in 2019, and primarily consisted of CH₄, and N₂O. Bangladesh’s agricultural emissions are mainly from rice cultivation, digestive processes of animals, manure, and poultry litter management. Emissions from agriculture accounted for 28% of total emissions in 2018 which is an improvement from the 2011, which was 35%. The decline is primarily due to the decline in GDP share of agriculture from 17% to 13% during this period.
In 2019, Bangladesh’s power sector accounted for 22% of emissions. Natural gas is the major fuel used in electricity generation in Bangladesh, accounting for 75% of generation, and despite continued emphasis from the country on renewable energy use the share of natural gas in its power sector has increased steadily.
Uncertainties remain around Bangladesh’s LULUCF emissions. However, its third national communication reported the sector as a source of emissions in 2012, contributing to around 5% of total GHG emissions in that year.
