Climate Emergency? What Climate emergency?

As Edie put it in this article, the declaration by the UK Parliament of a Climate Emergency is hugely symbolic. But is it any more than a symbol? The UK Government has been woefully lax in putting in place measures for the country to reach it's stated aim of 80% reduction by 2050, let alone the net zero position recommended recently by the CCC. The cynic in me is not holding my breath.
