Editing IPCC:AR6/WGIII/Chapter-4 (section)

==== 4.2.4.1 GHG Mitigation Target Under UNFCCC and Paris Agreement ====

<div id="h3-9-siblings" class="h3-siblings"></div>

The Paris Agreement requests that Parties should strive to formulate and communicate long-term low GHG development strategies by 2020. (Note that by ‘long-term’, the UNFCCC means 2050, which is the end point of the ‘mid-term’ horizon range in the present report.) As of August 25, 2021, 31 countries and the European Union had submitted low-emissions development strategies (LEDS) (Table 4.5).

By 2018, most long-term strategies targeted 80% emissions reduction in 2050 relative to a reference (1990, 2000 or 2005). After IPCC SR1.5 was published, the number of the countries aiming at net zero CO 2 or GHG emissions has been increasing. [[#footnote-000|6]]
