Solution

Vision Statement
Over the next 100 years we will (1) stabilize global anthropogenic carbon dioxide emissions, then (2) eliminate such global carbon dioxide emissions, and finally (3) decrease the overall atmospheric concentration of carbon dioxide to 350 parts per million.  By developing and integrating various methods of carbon capture and sequestration, we will establish a comprehensive and economically viable plan which, paired with emission reduction and renewable energy technology, can be implemented internationally.
Our Goal:

 
The following figure illustrates the overall impact of our plan. The top line shows the CO2 emissions that would be released assuming inaction. The semi-transparent section of the graph shows the amount of CO2 avoided and sequestered by the implementation of our plan. The solid orange section illustrates the amount of CO2 still released into the atmosphere.


Emissions Mathematical Models
In order to fulfill our vision statement, we modeled three solution timelines, each of which had the prospect of being implemented. The first timeline calls for stabilization of global carbon emissions by 2020 and the elimination of carbon dioxide emissions by 2035; the second, stabilization by 2035 and elimination by 2060; the last, stabilization by 2025 and elimination by 2060. The first scenario was so rigorously progressive it was economically unfeasible. The second scenario, while more economically favorable, did not curb emissions quickly enough and sacrificed environmental health. The final plan strikes a balance between the first and second plan and is the plan endorsed by this class. All three models and further explanations are included on this website.
 
Optimization Mathematical Model
To find the contribution of each technology, we created a cost-effect mathematical model. Using gross assumptions about the future economy and international development and integrating approximate parameters for each technology, we projected what could be accomplished over the hundred-year period. This model is included on this website.

Case Studies
To better apply our solution to the different types of nations in the world, we created three distinct categories of nations: nations with high carbon dioxide emissions but low population growth; nations with high emissions and high growth; and nations with low emissions but high growth. Example nations were selected for each category: the United States and the European Union exemplify the case of high emissions and low growth; China was selected to represent high emissions and high growth; and Brazil was chosen as an example for low emissions and high growth. A case study for each was made, analyzing each nation’s (or group of nation’s) current political, industrial, economic, and social situation. This information was then used to tailor the overall international plan to better fit each type of nation. These case studies and altered are included in this website.
