The issues thrown up by climate change have never been more urgent. It's politics, it's food, it's business - it's people's lives. 'The Art of Cutting Carbon' is a unique project which uses art installations commissioned by the BBC to highlight the carbon dioxide emitted by the big industries around us.
In his last film after 35 years at the BBC, Environment Analyst Roger Harrabin reports on the endeavours of British artists working with concrete, steel, aluminium, plastic and cardboard. On his journey around Europe, Roger is given exclusive access to world-leading technologies designed to cut carbon. He visits the zero-carbon steel in Sweden which emits only water vapour, and experiences 'edible' plastic bottles in the Netherlands.
