It could also help activists in their efforts to pressure producers or governments to cut fossil fuel output. The Global Registry of Fossil Fuels contains data for fields in 89 countries, covering 75% of global production the non-governmental organisations which developed it said. While there is little doubt that much of the world's oil and gas reserves will have to stay underground to avoid a dramatic worsening of the climate, the registry has put a number on this. It is not straightforward to calculate the life-cycle emissions of a unit of oil, gas or coal, often relying on calculations rather than measurements which can differ widely.
