Net Zero is a commitment to stop releasing excess carbon some decades hence. And such commitments will necessarily fail. As every potential groom and bride knows, a commitment for the future is no commitment at all. As every dieter knows, a commitment to lose weight in the future never works. You have to start today. And the world needs we need to commit to stop increasing our carbon footprint, and also start reducing it NOW. Even if a Net Zero commitment is honest, too many events can push countries off track. Some may get financially constrained (like Sri Lanka today) or face a power crunch (like China today and India getting there) or face internal or external war (like Afghanistan), or may elect an ostrich (like the USA sometime back), etc. Indeed, there are many possible challenges that make it impossible to keep to long-term global commitments.
The commitment I demand is not a Future Net Zero but Date Zero Today globally. That is, no more thermal power plants, interest-free credit for RE investment, and an international initiative to sequester carbon.
