Lord Jamieson (Con)

Amendment 187A, tabled in my name and that of my noble friend Lady Scott of Bybrook, seeks to probe the practical meaning of the new definitions, particularly the “achievement of sustainable development” and “mitigation” of climate change. Repetition signals importance; the fact that the same definition appears three times in such a short clause suggests it would carry significant legal and practical weight. That makes it vital that Parliament understands precisely what is meant. These terms, though laudable, are broad and open to interpretation. Without clear parameters, they risk being applied inconsistently by different authorities. If undefined, in unmeasurable or unenforceable terms, they could slip into the realm of aspiration rather than action, undermining their purpose as guiding principles for planning and infrastructure decisions. Ambiguity would not only weaken decision-making but could result in delays, disputes and costly appeals. I appreciate that the Government’s Amendment 187 is not grouped here, but it is relevant. That amendment creates a new clause clarifying the relationship between different types of development corporation, ensuring that any overlap is resolved in favour of the higher tier authority. Will the Government consider committing to something similar in relation to these definitions, so that we secure the same kind of clarity and consistency?
