- On 17 May 2021, International Energy Agency (IEA) released its report on Net Zero Emissions Roadmap-titled ‘Net Zero by 2050’.
What does Net Zero Emission Means?
- It means that, all Green HouseGases (CO2 methane etc.) emissions released by humans are counterbalanced by removing Green House Gases (GHSs) from the atmosphere.
About ‘Net Zero by 2050’ report
- It is world’s first comprehensive study of how to transition to a net zero energy system by 2050.
- It gives a roadmap to stable and affordable energy supplies with universal energy access while maintaining clean, dynamic and resilient energy economic system.
Need of ‘Net Zero by 2050’
- Number of countries have announced pledge to achieve net-zero emissions target, however questions are being asked whether net-zero emissions can be achieved globally by 2050 with a view to limiting global warming to 1.5°C.
- It also raises question over future of energy sector.
- Report gives the roadmap for the priority actions that are needed today to ensure the opportunity of net zero emissions by 2050.
Aim of the IEA Roadmap
Key milestones recommended in the Pathway to net zero
- Does not take account of historical emitters, ignoring ‘climate justice’.
- To follow these pathway citizens and companies will need to modify their behaviour through changes in economy, society & technology which will require large government investment & policy change and new laws which will be difficult to achieve globally.
- Does not take account of poor & developing economics who still need carbon intensive energy for their development needs.
Feasibility of Net Zero by 2050 for India
Conclusion and Way Forward
- To make this roadmap reality, global development in clean and green energy needs to vastly pick up the pace and accelerate technological innovation.
- Regulations should be made instead of over relying on behavioral change to consume less energy.
- Need for the world to reach Net Zero Emissions by 2050 lies in the major interim steps that need to be taken through 2030- to engineer cheap and green energy from hydrogen and renewable energy while making them accessible to all.
- Developing nations must be given extra financial and technological support by developed nations and burden of emissions of developed nation must not be forced on developing nation.
