The UK government has released a blueprint for expanding Heathrow Airport, labeling the project as essential to national economic growth. Transport Secretary Heidi Alexander launched a consultation on the Heathrow Expansion National Policy Statement (HENPS), outlining conditions for approval.
Heathrow Airport Limited (HAL) proposes a 3,500-metre runway costing £33 billion, funded entirely privately, which would require relocating the M25 motorway. The expansion would boost capacity to 756,000 flights and 150 million passengers annually. A rival proposal by tycoon Surinder Arora suggests a 2,800-metre runway that avoids moving the highway.
Alexander indicated in November her preference for the full-length runway, stating the project is "critical to national growth." The draft policy mandates applicants to show how transport networks can handle increased passenger numbers and requires compliance with climate targets, air quality limits, and noise reduction goals.
Chancellor Rachel Reeves expressed determination to begin construction by 2035, criticizing Heathrow for not "punching its weight" as an international hub. She highlighted the nation's long-standing failure to expand the airport.
Heathrow CEO Thomas Woldbye welcomed the government's step, emphasizing the airport's role in unlocking economic potential. However, climate charities oppose the plan. Alethea Warrington of Possible called it a "fantasy," warning of worse noise, toxic air, and climate impact.
