Protecting and Restoring Nature: COP15 and Beyond

I absolutely agree that there has to be a measurement of the effect on the natural world and the environment, measurements of human inequality and all the normal GDP measurements. Would it not be better if the UK Government set an aim to come away from the next round of discussions with an agreed position on how we will measure the effect on the natural world of economic activity as part of the whole measurement of GDP? In that way, it would be factored in and give a legal status and entity to the environment and the natural world, as opposed to just discussing it as a separate thing as a consequence of our own activities.
