==== 4.2.4.2 Other National Emission Pathways to Mid-century ====

<div id="h3-10-siblings" class="h3-siblings"></div>

At the 2019 Climate Action Summit, 77 countries indicated their aim to reach net zero CO 2 emissions by 2050, more the number of countries having submitted LEDS to the UNFCCC. Table 4.6 lists the countries that have a national net zero by 2050 target in laws, strategies or other documents ( [[#The%20Energy%20and%20Climate%20Intelligence%20Unit--2019|The Energy and Climate Intelligence Unit 2019]] ). Bhutan and Suriname already have achieved net negative emissions. France second ‘low-carbon national strategy’ adopted in 2020 has an objective of GHG neutrality by 2050. Net zero is also the basis of the recent revision of the official notional price of carbon for public investment in France ( [[#Quinet--2019|Quinet et al. 2019]] ). The Committee on Climate Change of the UK analyses sectoral options and concludes that delivering net zero GHG by 2050 is technically feasible but highly challenging ( [[#Committee%20on%20Climate%20Change--2019|Committee on Climate Change 2019]] ). For Germany, three steps to climate neutrality by 2050 are introduced: first, a 65% reduction of emissions by 2030; second, a complete switch to climate-neutral technologies, leading to a 95% cut in emissions, all relative to 1990 levels by 2050; and third balancing of residual emissions through carbon capture and storage (Prognos et al. 2020). In addition to the countries in Table 4.6, EU reported the net zero GHG emission pathways by 2050 under Green Deal ( [[#European%20Commission--2019|European Commission 2019]] ). China and South Korea, have made announcements of carbon neutrality before 2060 and net zero GHG emission by 2050, respectively ( [[#UN--2020a|UN 2020a]] ,b). In the case of Japan, the new target to net zero GHG emission by 2050 was announced in 2020 ( [[#UN--2020c|UN 2020c]] ). As of August 25, 2021, a total 121 countries participate in the ‘Climate Ambition Alliance: Net Zero 2050’, together with businesses, cities and regions.
