Zero Carbon Britain

In June last year the UK government committed us all to reaching net zero carbon emissions by 2050. To reach that ambitious target we're going to have to change the way we travel, heat our homes and farm our food. Tom Heap is joined by an expert panel to measure our progress and gauge our chances of reaching net zero. Tom's joined by physicist Helen Czerski of University College London, James Murray, editor of Business Green and the author of Our Final Warning, Mark Lynas. Producer: Alasdair Cross
