Whereas energy production has implications for CO2 production and mitigation strategies (80% or more of which are agricultural)
Furthermore block chains and smart contracts could have a role in enforcing the Paris agreement. Thus providing a serious alternative solution to the two existing methods of enforcement at the international level: sanctions followed by war.
