This is because the degree of carbonisation of organic material as measured with electron spin resonance is dependent only upon the amount of carbon and not on the time material has been heated for.
Many of the nations that are putting their faith in strong de-carbonisation and green growth national plans - such as the Maldives, Costa Rica, Mexico, South Korea, Brazil, the EU and others - now need to make a common cause.
