The Green House Gas Emission (GHGs) from the carp culture ponds (n = 12) of West Godavari, Krishna, and Guntur districts of Andhra Pradesh and from the ponds (n = 4) of Moyna, East Medinipur district of West Bengal, India was assessed through carbon storage and carbon footprint analysis. The average inputs as Carbon Equivalent (CE) were 14407 ± 2651, and 9231 ± 1007 kg/ha in Andhra Pradesh, and West Bengal, respectively. The average carbon storage were 6216 ± 2291, and 5360 ± 1439 kg/ha, in Andhra Pradesh, and Moyna, West Bengal respectively. The emissions of CO2-e and CH4-e were 1.91 ± 0.42 kg CO2-e/kg fish and 0.122 ± 0.027 kg CH4-e/kg fish, respectively in Andhra Pradesh. The emissions of CO2-e and CH4-e were 0.006 to 2.07 (average 0.72) kg CO2-e /kg fish, and 0.0004 to 0.132 (average 0.046) kg CH4-e /kg fish production, respectively in Moyna, West Bengal.

A field experiment was carried out at Agriculture Farm, Palli Siksha Bhavana, Visva-Bharati, Sriniketan, West Bengal, India during kharif season of 2015 to compare rice cultivation in conventional transplanting (CT) and system of rice intensification (SRI) in terms of energy use, energy input output relationship and green house gas emission. Results showed that regardless of cultivars, conventional transplanting consumed 62.39% higher energy over SRI. Maximum energy input was associated with non renewable and indirect sources. Higher dose of nitrogenous fertilizer had contributed to 32.35% and 26.26% to the total input energy in CT and SRI respectively. Energy use efficiency (13.22), energy productivity (6.94 kg MJ-1), energy profitability (12.22) and energy intensity (4.60 MJ Rs-1) of hybrid rice varieties were noted higher in SRI. Maximum green house gas emission from rice field was also attributed to fertilizer nitrogen followed by diesel in both the system. Total green house gas emission in CT was estimated to 834.85 (kg CO2ha-1) i.e. 1.8 times of SRI. Engirdling different energy indices, total input energy and green house gas emission, the system of rice intensification was emerged as the most energy efficient and sustainable rice production system in resource stricken areas (Red Lateritic Zone).

Protection of the Environment and Sustainability goes hand in hand as one mechanism compliments the other. On the other hand, Sustainable Economic Growth can only be achieved if it is linked to Ecologically Sustainable Development (ESD). Sustainability can best be described as "Living within the limit of what the environment can provide while safe guarding the environment for future generation, Understanding the many connections between environment, society and economy, and equitable distribution of resources and opportunities". Uncontrolled Green House Gas Emission has caused global warming, sea level rise, change of weather pattern (e.g severe untimely rainfall at unusual location), and alarming increase of natural disasters (Cyclone, Hurricane, Floods, Tsunamis and other natural phenomena). Third world countries are worst affected by the Green House Gas Emission and Global Warming Impact and Bangladesh is one of them. UN has taken a leading role and guiding the world to work together not only to reduce pollution but to make significant contribution in achieving pristine environmental conditions. Under the umbrella of UN, the world is now taking collective action to reduce Green House Gas Emission and Tackle Global Warming Impacts. Concerted efforts must be taken in an accelerated pace to educate at Global, Regional, National and Community level, about the benefits of the above-mentioned concepts and introduce incentive-based programs for mass participation. The environmental cleanup process should start from individual home and gradually extending to community, national and global level to achieve accelerated measurable success. An opportunity must be created to reform land use change, replacing pollution producing industries with environmentally sustainable practices. It is overdue to put through a series of EPA recommended processes to clean up the contaminated land, soil and water and secondly, introduce and adapt an Ecologically Sustainable Development program. The long-term goal should be to expedite and spread the land use change practices to relace the contaminated practices and introduce mandatory adaption of environment friendly technology for the ongoing industrial and business activities to reduce pollution while contributing improving the environment. With a global collective action this world can be transformed into a heaven on earth.
