Indian marine emissions lower than global average: CMFI study

The sector emits 1.32 tonnes of CO2 to produce one tonne of fish


A recent research study by the ICAR-Central Marine Fisheries Research Institute (CMFRI) has revealed that the carbon emissions from India's marine fisheries sector are significantly lower than the global average. The study was presented at a review meeting of the fisheries component of the National Innovations in Climate Resilient Agriculture (NICRA) network research project, highlighting the impact of the fishing industry on the environment.

The CMFRI research found that during the harvest phase of the fishing process, which involves active fishing, more than 90 percent of the fuel used in the sector is utilised. This information is crucial because it allows policymakers to identify areas where sustainable practices can be implemented, such as fuel-efficient fishing practices that would reduce the sector's carbon footprint.

The study by the ICAR-CMFRI team has shed light on the relatively low carbon footprint of India's marine fisheries sector compared to the global average. By adopting sustainable fishing practices that reduce carbon emissions, the fishing industry can help to mitigate the negative effects of climate change on marine ecosystems while also promoting economic growth and supporting local communities.

Grinson George, Principal Scientist of CMFRI, said the increased intensity of cyclones, sea level rise, and warming of the Indian Ocean have led to changes in marine ecosystems among many others, causing depletion of some fishes and the emergence of some other varieties.

The research assessed the carbon footprint of India's marine fisheries sector, estimating that it emits 1.32 tonnes of CO2 (carbon dioxide) to produce one tonne of fish, which is considerably lower than the global average of over two tonnes for the same quantity. This finding indicates that India's fishing industry has a relatively low carbon footprint compared to other countries, which is encouraging given the country's large population and high demand for fish.

"This is the assessment of the greenhouse gas (GHG) emissions from total activities in the sector, from pre-harvesting to marketing, by converting it into CO2 equivalent," CMFRI said in a statement.

"The country's carbon emissions from the marine mechanised fisheries sector is 16.3 per cent lower than the global level," Gopalakrishnan said.

S K Chaudhari, Deputy Director General (Natural Resources Management) of ICAR, who presided over the meeting, said the rise in temperature and heat have a cascading effect on food-producing sectors, including fisheries.

"Excessive pressure on groundwater is leading to the presence of more salts on the ground surface," he said, adding that assessing ecological losses should also be considered while studying the impact of climate change on the food sector.

B Venkateswarlu, Chairman of the NICRA Expert Committee, urged scientists to focus on technological innovations and contributions to policy interventions during the time of climate change.


Innovative technologies would help fishers to sustain their livelihood during cyclones, heavy rainfalls and other extreme weather conditions, he said.

The results of the study suggest that the Indian marine fisheries sector could potentially serve as a model for sustainable fishing practices in other countries. This is particularly relevant as climate change continues to threaten global marine ecosystems, causing declines in fish populations and other marine life. By adopting sustainable practices that reduce carbon emissions, such as fuel-efficient fishing methods, the fishing industry can help to mitigate the negative effects of climate change on marine ecosystems.
