Delivery of the Seventh Carbon Budget relies on nascent technologies and on greenhouse gas removals, including both land-based approaches and engineered removals, some of which face significant uncertainty over scale, cost, and delivery timescales. While these options are necessary for addressing genuinely residual emissions, increasing reliance on them shifts delivery risk towards the later stages of the pathway. This defers, rather than resolves, uncertainty, reduces resilience and limits the scope for corrective action if earlier mitigation falls behind. (Conclusion, Paragraph 92)
