Mandatory Carbon Reporting For UK Companies

The government has announced that, from April 2013, top UK companies listed on the Stock Exchange will have to report their carbon footprint annually. It's estimated that it will be compulsory for around 1100 companies.

Furthermore, after review in 2015, it's expected to be rolled out to all large businesses in 2016.

Some may see this as yet more needless red-tape but it has been shown in trials that it's actually benefits companies. Essentially they get to see where their business is losing money due to poor energy efficiency.
