GHG Mitigation Assessment Model DNE21+

Research Institute of Innovative Technology for the Earth (RITE) ‘s DNE21+ model is a greenhouse gas (GHG) mitigation assessment model for energy related CO2 emissions.

DNE21+ is an intertemporal linear programming model for assessing global energy systems and global warming mitigation options. It represents energy systems (e.g., energy flows, capacities of energy related facilities) consistently in which the sum of the discounted total energy systems costs are minimized. The model represents regional differences and assesses detailed energy-related CO2 emission reduction technologies up to 2050.

Key questions addressed:

  • What are the costs associated with various power technologies, and energy efficiency measures, and carbon capture and sequestration?
  • What is the impact of climate related policies (e.g., carbon tax, cap and trade, preferred tax by technology) on the global economy?

Sample data inputs:

  • Unit operation costs
  • World annual production potential
  • Available technologies
  • Population and GDP
  • Energy demand

Sample quantitative outputs:

  • World carbon emission trajectories
  • Energy intensity
  • Carbon intensity
  • Carbon emissions from fuel combustion
  • Emission reduction costs
