Air Emissions

Our air emissions predominantly consist of products of combustion associated with power generation and LNG train compressor turbines, both using turbine technology.
 
Woodside regularly monitors and measures air emissions and also develops technical solutions to reduce these emissions. Typically, new facilities and expansions offer the most significant opportunities to improve efficiency as they do not cause interruptions to production commitments on operating facilities.
 
A comparison of our emissions performance figures for the previous five years is shown in the table below (which also appeared in Woodside’s 2010 Sustainable Development Report).
