Answer: Japan
Notes: Recently, Japan launched the Global Observing Satellite for Greenhouse gases and Water cycle (GOSAT-GW) from Tanegashima Space Centre. GOSAT-GW is an Earth observation satellite developed by the Japanese Aerospace Exploration Agency (JAXA). It was launched using the H-2A rocket. Its objectives are to monitor global-mean concentrations of Greenhouse Gases (GHGs), verify national anthropogenic GHG emissions inventories, and detect GHG emissions from large sources like megacities and power plants.
