• In 2012, international shipping was estimated to have contributed about 2.2% to the global emissions of CO[subscript]2, according to the International Maritime Organisation (IMO). "Although international shipping is the most energy efficient mode of mass transport and only a modest contributor to overall CO[subscript]2 emissions, a global approach to further improve its energy efficiency and effective emission control is needed as sea transport will continue growing apace with world trade," says the IMO.

  By way of comparison with shipping emissions, according to European Union's Environment Agency (EEA), soda ash production and consumption (including sodium carbonate, Na[subscript]2 CO[subscript]3 ) results in the release of pollutants, the main pollutant being CO[subscript]2. It is good practice to report this pollutant in compliance with the Intergovernmental Panel on Climate Change (IPCC) Guidelines for National Greenhouse Gas Inventories (IPCC, 2006). On average, 200-300kg CO[subscript]2 are vented into the atmosphere per tonne of soda ash produced.
