PARIS—The European Union reached an agreement to impose a tax on imports based on the greenhouse gases emitted to make them, inserting climate-change regulation for the first time into the rules of global trade.
The deal on Tuesday morning between European national governments and the European Parliament ends more than a year of negotiations on the details of the plan. The EU is expected to adopt it in the coming weeks as part of a sweeping package of legislation that would step up the bloc’s efforts to limit global warming.
