European Union lawmakers backed a watered-down law on "green crime" on Monday that would make dumping toxic waste or illegally transporting hazardous materials a criminal offence throughout the bloc. The draft law obliges the EU's 27 member states to treat and punish as criminal acts a list of nine offences ranging from harming protected plants or species to unlawful trade in ozone-depleting substances. But it does not set EU-wide sanctions to the dismay of environmentalists who doubt it will have much impact.
