CNBC's Sustainable Energy takes a look at some of the world's biggest exporters of liquefied natural gas, otherwise known as LNG.

The information shows LNG exports in million tonnes (MT) and market share, and comes from the International Gas Union's (IGU) 2017 World LNG Report, with data coming from both the IGU and IHS Markit.

Papua New Guinea is home to the $19 billion PNG LNG Project, which is operated by ExxonMobil PNG Limited.

Operations began in 2014, and 2016 saw the project produce 7.9 million tonnes of LNG.

Oman LNG was set up by a royal decree back in 1994.

Its operations plant is based on a site around 200 kilometers south east of Muscat, and has a capacity of 34 million cubic meters per day.

Trinidad and Tobago's Atlantic LNG says that, as a company, it is "one of the world's largest producers" of LNG.

According to the World Bank, Trinidad and Tobago's economy is "largely based on oil and gas production."

Gas giant Gazprom says that it currently supplies LNG to more than 10 countries, including the U.S., China, the U.K. and India.

Sakhalin II was Russia's first LNG plant and came onstream in 2009.

According to the IGU, Algerian production of LNG fell for the second year in a row in 2016.

Nevertheless, it says that Algeria is among a select group of countries that account for over 60 percent of the planet's "nominal liquefaction capacity".

While Indonesia is fifth in terms of LNG exports and market share, the IGU says that a combination of greater domestic demand and falling domestic production could eventually result in lower exports.

Nigeria LNG – which employs more than 1,000 people– says that its plant on Bonny Island, in Rivers State, has the ability to generate 22 million tonnes per annum of LNG.

Malaysia is something of a powerhouse when it comes to LNG.

The Petronas LNG Complex, for instance, is located in Bintulu, Sarawak, and has a capacity of 24 million tonnes per annum.

According to the Australian Petroleum Production & Exploration Association (APPEA), Australia is home to seven operational LNG projects, with three more being developed.

APPEA says that LNG is "driving an unprecedented level of investment in Australia."

Qatar is blessed with an abundance of natural gas. LNG producer Qatargas says that it is the largest in the world, and has a production capacity of 42 million tonnes per annum.

At the end of 2016, it was announced that Qatargas and RasGas, the Gulf state's other LNG producer, would merge.
