California is suing the US federal government, in an attempt to force car makers to conform to tougher cuts in greenhouse gas emissions.

The lawsuit comes after the federal Environmental Protection Agency denied California a waiver from US law needed to enact its own efficiency targets.

The Epa says it wants to avoid a confusing patchwork of different regulations across states.

But California says the Epa has "done nothing" to curb greenhouse gases.
