Analysis of methane emissions from natural gas and oil systems: 1990-2010

28159

The concentrations of anthropogenic emissions of greenhouse gases (GHG) in the atmosphere have considerably increased in recent years. This has caused to an increase in the greenhouse effect. Methane (CH_4), one of the greenhouse gases, is emitted from a variety of sources and its concentration in atmosphere has increased dramatically over the last few centuries. Natural gas and oil systems are one of the important sources of methane emissions whose concentration in atmosphere has rapidly increased. It is, therefore, highly important to determine the primary sources of emissions in terms of regions and countries. This paper examines the methane emissions from natural gas and oil systems from 1990 to 2010. It analyses the changes in methane emissions on the basis of geographic scale. Results indicate that the non-European Union nations had the biggest share in global methane emissions. Between these nations, Russian Federation was the highest emitter and its natural gas emissions dominate the region’s emissions. Following the non- European Union nations, OECD countries and current members of the European Union were the next biggest contributors to the emissions. The United States was responsible for the majority of emissions in this group. Results also showed that these emissions can be decreased by nearly 100% using technology or equipment upgrades, improving management practices and operational procedures to reduce venting, enhancing management practices.
