water vaporHas a greenhouse effect and contributes the most to the greenhouse effect[6]..It also has the function of transporting heat toward outer space through evaporation and rainfall.Although the amount of artificial water vapor generated does not cause significant climate change, it is said that the above-mentioned substances trigger climate change and water vapor amplifies its warming effect.Causes of Global Warming #Influential Factors and MechanismsSee).thiswater vaporSome people argue for skepticism about climate change by capturing only part of their work (Skepticism about global warming #water vaporSee).

Global warming potential

Global warming potential(Chikyu Ondan Kakeisuu,British: global warming potential[7],GWP) Is a comparison of the 100-year strength of the greenhouse effect per concentration when various gases are released into the atmosphere, based on carbon dioxide.[8].. Redefined as "2016-year global warming potential" in the revision of the Montreal Protocol on substances that destroy the ozone layer (Montreal Protocol 10 revision) adopted in Kigali on October 15, 2016.[9].

Emission status

World emissions

Emissions from major countries in the world reached about 2010 billion tons in terms of carbon dioxide as of 427.[11].. As of 2010, China (23%) had the highest emissions, followed by the United States (16%), India (5.7%), Russia (5.4%), Japan (2.9%), and Brazil (2.6%). ), Germany (2.1%), Indonesia (1.9%), Canada (1.7%), Iran (1.6%).

In addition, the aggregated results of the UNFCCC (United Nations Framework Convention on Climate Change) Secretariat, which is a subordinate organization of the United Nations,Greenhouse gas inventoryIt is published in.

Japan's emissions

Greenhouse gas emissions in Japan reached a record high (2007 million tons in terms of carbon dioxide) in FY13.[12]. afterwards,Lehman shockDue to the influence of the above, emissions have fallen below the previous year's level for the second consecutive year in 2008 and 2009. 2011Fukushima Daiichi Nuclear Power Plant AccidentAfter the outbreak, the power source composition changed from nuclear power to thermal power[13]As a result, emissions have exceeded the previous year's levels for the second consecutive year in 2011 and 2012.

Detailed numbers areJapan Greenhouse Gas InventoryIt is published in.This is the value officially submitted by Japan to the Conference of the Parties to the United Nations Framework Convention on Climate Change (through the UNFCCC Secretariat).
