According to the IPCC report of 2018, it states that the net emissions must be reduced to zero in order to stabilize the global temperature.
The objective has been initiated by Switzerland, EU and many other countries under the Paris agreement. As in article 4.1 of Paris Agreement it clearly states the need to “to achieve a balance between anthropogenic emissions by sources and removals by sinks of greenhouse gases in the second half of this century(UNFCCC, 2015)”. Implementation of national net zero targets can play a crucial role in limiting global warming to 1.5˚C, which requires carbon dioxide (CO2) and other greenhouse gas (GHG) emissions to rapidly decrease to net zero around 2050 and 2070, respectively. After that, emissions should decrease to be net negative (IPCC, 2018).
The global warming all over the world has been increased by 1.5℃
India’s Prime Minister, Narendra Modi on 1st Nov used the COP26 climate talks to announce 2070 as the target for his country to reach net zero carbon emissions, two decades beyond what scientists say is needed to avert catastrophic climate impacts. Narendra Modi defended India, however, as having stuck to its climate pledges “in spirit and letter” and noted that his country contained 17% of the world’s population but was responsible for only 5% of global emissions. Modi told other world leaders that India would increase the share of renewables in its energy mix from about 38% last year to 50% by 2030.
The United States, Britain and the European Union have set a target date of 2050 to reach net zero, by which point they will only emit an amount of greenhouse gases that can be absorbed by forests, crops, soils and nascent “carbon capture technology”.
China and Saudi Arabia have both set targets for 2060, but critics say these are largely meaningless without tangible action now.
Scientists say the world needs to halve global emissions by 2030 and reach net zero by 2050 to avoid the worst impacts of climate change.
