Andy Burnham, the Manchester mayor, has said he will not support the proposal for a third runway at Heathrow until the outcomes of a forthcoming consultation are known, according to BBC Business.

Burnham’s statement comes amid a broader debate over the expansion of the UK’s busiest airport, which has been linked to a projected cost of £33 billion. The consultation, which is scheduled to examine the technical, economic and environmental aspects of the scheme, will provide the evidence needed for policymakers to decide whether the additional capacity is justified.

The mayor’s position reflects concerns shared by many local and environmental groups that a third runway could exacerbate noise pollution, air‑quality problems and carbon emissions, while also raising questions about the value of the investment. By waiting for the consultation, Burnham signals a cautious approach that prioritises evidence and public input over political expediency.

As the consultation process moves forward, stakeholders will be able to influence the final decision. Burnham’s stance suggests that the outcome of the consultation will be a decisive factor in whether the Heathrow expansion goes ahead, potentially shaping the future of air travel and economic development in the region.
