RasGas has completed a 10-year low nitrogen oxide (NOx) retrofit programme across Trains 1, 2, 3, 4, Al Khaleej Gas 1, and associated utilities, reducing its nitrogen oxides (NOx) emissions intensity by approximately 90% in comparison to 2006 levels.
The programme, which was implemented in cooperation with the Ministry of Municipality and Environment (MME), is a significant step in mitigating environmental concerns about local air quality. 
RasGas introduced General Electric’s (GE) Dry Low NOx technology in 2007 to the company’s gas-fired turbines built before 2005. It subsequently ensured that emissions from all applicable combustion units meet, or fall below, Qatar’s applicable regulatory limits.
RasGas chief executive officer Hamad Mubarak al-Muhannadi said, “As a responsible corporate citizen, we believe it is our duty to make a positive environmental contribution where we can, and to mitigate any impacts associated with the activities under our control as far as possible. As a Qatari company, we also embrace our responsibilities to our local communities, and this includes ensuring we play a constructive role in protecting the quality of ambient air.”
Air emissions from the oil and gas industry operations may contribute to local environmental impacts such as haze, and can affect health, flora and fauna. These emissions include NOx and sulphur dioxide emitted during combustion.
RasGas has long been committed to addressing such environmental challenges, including forming a specially appointed emissions reduction steering committee comprising senior management that is responsible for identifying and coordinating opportunities for emission reductions. 
A 2014 ‘Philip Townsend Associates Incorporated’ benchmarking report confirmed that the company’s NOx emissions intensity, expressed in weight percentage of total intake, was better than the LNG industry average by 70%, with RasGas ranking top of the 14 benchmarked LNG companies.
RasGas is a Qatari joint stock company established in 2001 by Qatar Petroleum and ExxonMobil RasGas Inc. RasGas acts as the operating company for and on behalf of the owners of the liquefied natural gas (LNG) projects RL, RL (II) and RL3.
With operations facilities based in Ras Laffan, RasGas’ principal activities are to extract, process, liquefy, store and export LNG and its derivatives from the North Field. 
RasGas, on behalf of the project owners, exports to countries across Asia, Europe and the Americas with a total LNG production capacity of approximately 37mn tonnes a year.
