• The story: The world is witnessing a raft of announcements and proposed intentions to achieve carbon neutral status by mid-century, 2050.
• The goal: The UN Secretary General has urged all countries, especially India, to make explicit declarations in the climate targets. Article 4.1 of the Paris Agreement asks countries to reach global peaking of greenhouse gas emissions as soon as possible. It requires countries to undertake rapid reductions in carbon emissions to achieve a balance between anthropogenic emissions by sources and removals by sinks of greenhouse gases. The temperature goal referred in the Paris Agreement is to limit temperature rise to well below 2°C and further pursuing efforts to restrict it to 1.5°C above pre-industrial levels.
• Target problematic: Climate change is not a national issue, but a global one. The balance between emissions and removal of greenhouse gases is sought not on a country-wise basis but for the world as a whole. The carbon neutrality goals of the countries do not reflect the principle of equity and the principle of common but differentiated responsibility, and are incompatible with achieving the goal of 1.5°C or 2°C. The three-way compatibility between temperature goals, carbon neutrality and equity is not guaranteed. 

1. According to IPCC reports, for a 50% probability of restricting temperature rise to less than 1.5°C, there should be carbon budget of 480 Giga-tonnes of carbon dioxide equivalent (GtCO2eq).
2. At the current rate of emissions of about 42 GtCO2eq per year, this budget would be consumed in 12 years. To keep within the 480 Gt budget, global carbon neutrality must be reached by 2039 which is infeasible.

• West's emissions: In the US, emissions have peaked in 2005 and have declined at an average rate of 1.1% from then till 2017, with a maximum annual reduction of 6.3% in 2009. If it reaches net-zero by 2050, the cumulative emissions between 2018 and 2050 would be 106 GtCO2 which is 22% of the total remaining carbon budget- very high share. If the US stays within its fair share of the remaining carbon budget, it would have to reach net zero emissions by 2025. It would still owe a carbon debt of 470 GtCO2 to the rest of the world for having used more than its fair share of carbon space in the past. The European Union, to keep to its fair share of the remaining carbon budget would have to reach net zero by 2033, with a constant annual reduction in emissions. The climate policy modelling has promoted the illusion that three-way compatibility is feasible through negative emissions by expanding the carbon capture. They also promote the other illusion that not resorting to any serious emissions increase is the means to guarantee the successful development of the third world.
• India and carbon neutrality declarations: India’s twin burden of low-carbon development and adaptation to climate impacts requires serious, concerted action. India has to stay focused on development — both as its immediate need as well as its aspirational goal. PM Modi has given the grand goal of $5 trillion GDP by 2025, and is working hard towards it. India’s current low carbon footprint is a consequence of the utter poverty and deprivation. Also, India does not owe a carbon debt to the world as the country’s emissions is not more than 3.5% of global cumulative emissions prior to 1990 and about 5% since till 2018. Its mitigation efforts are quite compatible with a 2°C target. Any self-sacrificial declaration of carbon neutrality will only reduce the burden of the developed world and transfer it to the backs of the Indian people. India’s approach to eventual net-zero emissions should be contingent on deep first world emissions reductions. Meanwhile, India must reject any attempt to restrict its options and being led into a low-development trap.
