Efficacy of a net-zero target

Summary

  • Countries worldwide are proceeding towards net-zero targets by strategising and implementing green policies.
  • The net-zero emission target is significant to keep the global temperature within 1.5 degrees celsius.
  • To detail a successful net-zero target, the Climate Action Tracker came up with a ten-step evaluation methodology to understand the national net-zero target’s scope, implementation, and benefits.

Gradually more and more countries are announcing national net-zero targets. At present, around 100 countries have taken a step ahead in the rollercoaster of reducing their emissions and reaching the state of net-zero emissions.

The titbits of net-zero emissions

Countries worldwide are proceeding towards net-zero targets by strategising and implementing green policies. A nation will achieve net-zero emissions when it removes the level of carbon dioxide that it produces - basically cutting all the excess carbon dioxide to maintain environmental sustainability. This is also called “Carbon neutrality.”

Substance in the net-zero emissions

World powers have adjoined hands in the Paris Agreement to achieve net-zero emissions by 2050. As a result, slowly and steadily, more heed is given to investment in renewables and green technology because that is the primary way to eliminate fossil fuel dependency.

The level of carbon and related emissions is increasing at a robust rate, because of which climate change has become a severe threat to humanity. In addition, an increase in draughts, bushfires, and other unprecedented climatic conditions are seen as a consequence of increasing global warming.

The net-zero emission target is significant to keep the global temperature within 1.5 degrees celsius. Life on earth will no longer sustain naturally if greenhouse emissions are not put into control.

In this marathon of achieving carbon neutrality, countries are announcing their strategies of cutting emissions. However, there are drawbacks to the policies in terms of practical implementation, transparency, etc. Thus, it is imperative to understand the efficacy of a net-zero target.

What is an excellent net-zero target?

To detail a successful net-zero target, the Climate Action Tracker came up with a ten-step evaluation methodology to understand the national net-zero targets’ scope, implementation, and benefits.

Target year - The national net-zero target year should be aligned with the global target of achieving net carbon emissions by 2050 and total net emissions by 2070.

Emissions - The net-zero policies should include all greenhouse emissions; the policies should be wholesome and circular.

International aviation and shipping - Every bit of emissions from all the industries are needed to be included. Thus, International aviation and shipping should be included in the national net-zero targets.

Removals outside borders - Countries that rely on reductions outside their borders to achieve the net-zero target put a hindrance in the net-zero global emission target.

Legality - The legal status of the national emission target should be crystal clear; then, only industries and state governments can move ahead to implement necessary duties and guidelines.

Sub-removal targets - To achieve the larger goal, smaller goals are needed to be set. Therefore, a comprehensive and transparent plan will include sub-targets to be achieved at different time intervals.

Review - Federal governments need to set the review process to keep an eye on achieving net-zero emissions within the time frame.

Emissions removal - How are emissions removed is a question to be addressed on top priority. Policies should be cautious of the use of forests and other land areas for carbon removal.

Comprehensive planning - Comprehensive planning is needed for timely decarbonisation, and for that, short and medium-term goals are needed in action.

Target clarity - The national target should clarify how it is fair and contributes to achieving net-zero global emissions by 2050.

The Climate Action Tracker collectively separates national net-zero targets of countries into three categories: acceptable, average, and poor, based on the above methodology. Therefore, it is essential to realise which country is bringing a change and which one is simply pretending to achieve the net-emissions target.
