ChinaYesYesOver 65% carbon intensity reduction below 2005 by 2030-1830, see notes.-1830, see notes.60-65% carbon intensity reduction below 2005 by 203023.9%Net zero by 2060Based on our preliminary data estimates, the change in 2030 emissions for China’s NDC, relative to its previous NDC, is 1830 MtCO2. Please note that our methodology compares the ends of the range that would result in the highest levels of emissions. In the case of China, this means comparing the 65% to 60% in carbon intensity reduction below 2005 levels by 2030.

South AfricaYesYes350-420 MtCO2e by 2030 -194-194398-614 MtCO2e by 20301.1%No targetAlthough South Africa's long-term strategy only commits the country to following a "peak, plateau, and decline" trajectory, capping 2050 emissions at 428 MtCO2e, interest in a net-zero trajectory is conveyed. The strategy notes that it is a living document, which represents the "beginning of [the country's] journey towards ultimately reaching a net-zero carbon economy by 2050.

BrazilYesNo43% below 2005 by 2030420.6380, see notes43% below 2005 by 20302.9%Net zero by 2050On 1 November 2021, Brazil announced a revised 2030 emissions reduction target of 50% by 2030. The details of the new target are not clear as Brazil is yet to officially communicate its revised NDC and provide clear information about the target's base year and baseline emissions. Our preliminary estimate is based on Brazil's 4th National Emissions Inventory, and using GWP-AR5 2005 levels for the base year emissions.

The country's long- term strategy notes that Indonesia is "exploring [the] opportunity to rapidly progress towards net-zero emission in 2060 or sooner."
21
South KoreaYesNo24.4% below 2017 by 20300.2-99.5, see notes.37% below BAU by 20301.4%Net zero by 2050At the UN World Leaders Summit in November 2021, South Korea announced its intention to reduce emission by 40% in 2030 below 2018 levels. South Korea is yet to formally communicate its revised target ot the UN.

IndiaNoN/AN/AN/A-1008, see notes.33-35% emissions intensity reduction below 2005 by 20306.8%Net zero by 2070Based on our preliminary data estimates, the change in 2030 emissions for India's announced intensity target (45% reduction by 2030), relative to its previous NDC, is 1008 MtCO2. Please note that our methodology compares the ends of the range that would result in the highest levels of emissions. In the case of India, this means comparing the 45% to 33% in emissions intensity reduction below 2005 levels by 2030.6.8%

G20 members that have submitted NDCs with enhanced 2030 emissions reduction targets compared to previous NDCs
28
G20 members that have not yet submitted new or updated NDCs
29
G20 members that have submitted NDCs that are the same or weaker compared to previous NDCs

Notes:

1- The method for determining whether and to what extent G20 members have enhanced their nationally determined contributions (NDCs) with respect to greenhouse gas (GHG) mitigation is based off WRI's technical note for determining the impact of NDC Enhancement on Country-Level Emissions.
