The bill as amended would make the NDC the 2030 target. The government can amend the NDC from time to time, and the Paris Agreement calls on parties to continually increase their ambition. As we have observed over the past few years, and most strikingly with the issuance of the so-called 1.5°C report by the IPCC, the consensus around the science, not just around the effects of greenhouse gases and climate change but around the timing and urgency for action, can evolve. That is the reason this provision is in the act, to enable targets to be updated if, for example, there is an evolution in the science.
I would remind members that this authority would be constrained by the amendments that were made to the bill last week, which would require each successive target to be more ambitious than the previous one. In other words, with that amendment and this provision that's in the bill, it would be possible to change targets, but only to make them more ambitious, not to go backwards.
