The Globe and Mail reports in its Saturday edition that Britain's highest court has ruled that local councils and planning groups must consider the full environmental impact of new fossil fuel projects when deciding whether to approve them -- a decision that could have far-reaching consequences and that climate activists hailed as a major victory. A New York Times dispatch to The Globe says that the ruling will make it harder for Britain to move ahead with plans to develop large offshore oil fields in the North Sea, including Rosebank, one of the country's largest undeveloped oil fields. Situated off the coast of Scotland, Rosebank contains an estimated 300 million barrels of recoverable oil. "This is hugely significant, not just in the U.K. but in the world," said Annalisa Savaresi at the University of Stirling in Scotland. "It's not the end of oil, but it's definitely an important procedural step that has been long overdue." The U.S. Securities and Exchange Commission unveiled a watered-down proposal in March that did not require companies to disclose the emissions produced by their suppliers or consumers. Companies had argued that disclosing the full climate impact of projects would be too complicated and expensive.
