CIEL looks at climate impacts for real people instead of regional averages by comparing an individual’s climate damages in a given year to her savings from not reducing emissions. Using CIEL can help us think about whether we are net winners (savings greater than costs) or net losers (costs greater than savings) today, and how that is likely to change over time.

As policymakers negotiate the future of our climate, it is absolutely vital that they have in mind not just the potential impacts on a few “average” people, but the wide diversity of effects that will be felt by every person around the world.

The policy report examines discusses this wide range of climate impacts, and includes a special case study on the Caribbean (also available in Spanish).

Visit the SEI-CIEL website for a more detailed, step-by-step explanation of CIEL or to download the CIEL Excel tool, which allows users to graph their own net impact.

Note: This report is part of a package that also includes a policy brief of the same title and The CIEL Backgrounder: Understanding the Climate Impact Equity Lens.
