Value Proposition

Gas-CAP is a tool to evaluate the global emissions impact of national or sectoral emissions decisions.  The user can set a global CO2 emission target and then develop trajectories consistent with that emissions limit.  The analysis can be conducted at the national level or based on industrial sectors.

Gas-CAP and the Climate Bottom Line

Gas-CAP is the simplest and one of the few publicly available tools that focuses solely on the climate bottom line:  CO2 emissions and atmospheric concentration.

Gas-CAP addresses the Impact (“I”) of the oft-referenced I=PAT equation: 

Impact (Emissions) = Population * Affluence (GDP per capita) * Technology (Emissions/GDP)

Many existing climate & energy tools address the Technology (emissions/GDP) component of IPAT, and Gas-CAP does not attempt to replicate this work.  Gas-CAP assumes that users have a familiarity with the population growth, GDP growth, and Technology dimensions of the climate challenge.  The tool allows the user to summarize their knowledge into country- & sector-level emissions trajectories, thus focusing discussion on the focus of international target-setting: the climate bottom line of emissions & atmospheric concentration.

Gas-CAP versus Other Emissions Models

Only a handful of publicly available tools focus on the climate bottom line of emissions & atmospheric concentration.  These existing tools are in some cases more sophisticated, but offer a limited set of scenarios and involve more complicated user interfaces.  Existing tools include the FAIR model by the Netherlands Environmental Assessment Agency and the Contraction & Convergence model by the Global Commons Institute. 

Gas-CAP is designed to be a non-prescriptive, flexible sandbox with an immediately understandable interface.  It offers  experts and non-experts alike the opportunity to create emissions trajectories to fit any political perspective, and focuses discussion clearly on the climate bottom line.
