This study utilized a descriptive type of research. Annual methane gas emissions were identified in each country worldwide. The amount of methane gas emission every year was utilized using secondary data available from the internet. In this study, the trend of methane gas emission is analyzed by getting its average concentration in a forty-two (42) year production from 1970-2012. The highest volume of methane gas is observed in Asia while the least volume is registered by the Australian continent. Symbolic regression was used for curve-fitting rather than the traditional model –based regression analysis. The results indicated that Asian continent has the highest methane gas outputs with volatility of trends over time. Most of the countries in Asia are developing or underdeveloped which have bigger space for rapid industrialization in the name of development. This could be attributed to its booming industries and high agriculture animal production. The production period of agricultural animals directly affects the concentration of methane gas because of the amount of their waste products that are soon to be decomposed by microorganisms. However, Australia has the most stagnant concentration of methane gas among all the sampled continents due to the fact that this continent was already highly revolutionized by computer modernization, and the production of agricultural animals was maintained for numerous years.
