And more about some country's CO2 reduction offering

This is from the Guardian, it shows the current offering at the conference in Denmark...

Clearly the position of China is absurd (INCREASE CO2!!!) and there are lots of variations, you would think they could get their numbers on a level playing field, wouldn't you?

I suggest a simple way, first spreadsheet to list Mt CO2 reduction by country, the total to be what they scientists say is needed to keep the world's temperature below 2℃ - keep negotiating until we get there.

Then another spreadsheet with the costs, and the offer of each country towards the total needed.

Third a final spreadsheet allocating the money to who needs it, both for ameliorating the effects of global warming + the cost of implementation.

Job Done.
