France is cutting flights, but will the move cut carbon?

<p>From the BBC World Service: A few years ago, France came up with an idea to cut carbon emissions — reduce some short domestic flights and that&#8217;s now been signed into law. It affects flights where there&#8217;s an option to take a train in less than two-and-a-half hours instead. But how comprehensive and impactful will it really be? And, another industry under scrutiny is steelmaking which is responsible for 8% of global carbon emissions. We hear from a project in northern Sweden where they&#8217;re trying to do away with old carbon-intensive coal-fired blast furnaces.</p>
