What is net zero?
- Over 50 countries and major entities, including the US, EU, and China, have pledged to reach net zero by 2050 or before 2060, collectively covering more than two-thirds of the global economy.
- Achieving these targets requires transitioning from an annual emissions output of approximately 40 billion tonnes to a future system capable of removing billions of tons annually.
- Reliance on unproven negative emissions technologies presents a significant risk, as current innovations range from ambitious to experimental without demonstrated scale.
- There is a concern that delays in immediate emission reductions, driven by hopes for cheaper future technologies, could render negative emissions insufficient or unavailable when needed.
- A strategic risk exists that current pledges may enable excessive current pollution by assuming future technological fixes, while emerging markets assert rights to prioritize poverty alleviation over paying for negative emissions.
- The path to net zero is expected to demand universal participation across all economies, governments, and citizens, necessitating both technological innovation and a fundamental shift in global mindsets.
- While targets aim to provide policy direction and investment certainty, there is a documented history of falling short of goals, indicating a likelihood that future net zero commitments may also be missed.
