A Simple Primer on CORSIA
The Carbon Offsetting and Reduction Scheme for International Aviation known as CORSIA sets a global baseline of 2019 emissions. Any international flight that produces more carbon dioxide than this baseline must be balanced by purchasing and cancelling emissions units. Airlines can either buy approved credits or use sustainable aviation fuel that meets strict life cycle tests.
The Offset Paradox
ICAO member states created the rule that airlines must acquire eligible emissions units. Yet only states can authorise those units to leave their national carbon accounts. In practice many states have said yes to the obligation but have not yet opened the tap. The paradox resembles asking shoppers to pay for water in a shop with empty shelves. Prices climb, confidence shrinks and the climate receives no benefit.
A Non Obvious Insight
Several developing states already hold large volumes of Paris Agreement credits earned through renewable energy and forestry. Authorising just a fraction of those credits for CORSIA would not weaken national climate pledges. In fact doing so could finance new clean power for the same communities. Thus releasing units can strengthen rather than threaten domestic ambitions, an opportunity that even some environment ministries have overlooked. This win win pathway is vurdhaan in action.
Lessons From History
Aviation grew safely after World War Two because nations trusted one shared rulebook. Uniform safety and navigation standards removed friction and uncertainty. CORSIA extends that tradition to climate responsibility. Fragmented ticket taxes or separate regional schemes would bring confusion, double payments and trade disputes. History suggests clarity creates prosperity.
Practical Steps for Governments
1. Publish transparent criteria for authorising credits that mirror ICAO guidance. 2. Map national project pipelines in forestry renewable power and waste management that can generate future units. 3. Offer early access to units at stable prices to reduce market shocks. 4. Retire outdated passenger taxes once CORSIA is fully supplied to avoid double charging travellers.
Benefits Beyond Carbon
Approved emissions units bring verified social co benefits. A reforestation credit can create rural jobs, protect wildlife habitats and attract eco tourism. A solar farm credit can electrify remote clinics and schools. When airlines finance such projects the resulting money flows directly to communities rather than into general treasuries.
Conclusion
CORSIA provides a ready made framework to decarbonise international flying while advancing development goals. Its success now depends on political will rather than new technology. By promptly releasing eligible units states can earn revenue, airlines can comply fairly and passengers can continue exploring our connected planet with a lighter footprint.
