The UK Government's plan to build a third runway at Heathrow Airport has faced a serious hurdle after a judge recommended a review of the project's climate change and economic impact.
High Court judge Robert Carnwath said the government must prepare a national policy statement before going ahead with the expansion project, according to Reuters.
Carnwath ruled that the statement will have to involve a review of all the relevant policy issues, including the impact of climate change policy.
The national policy statement will also have to consider the economic impact of a third runway.
In January 2009, the government gave its approval to build a third runway and a terminal at Heathrow Airport, as part of a £9bn ($13.4bn) expansion programme to enhance its capacity.
The project was fiercely opposed by local residents and environmentalists on the grounds that it will increase the level of noise and carbon emissions.
