Model Assumptions

What are some of the key assumptions underlying the En-ROADS Baseline scenario?
All equations and parameters in En-ROADS are included in the extensive Reference Guide. Some of the key assumptions are listed below. For the En-ROADS B...

Does En-ROADS include climate “tipping points” such as large-scale methane release from permafrost?
En-ROADS does not include explicit modeling of climate “tipping points,” but you can explore some of them for yourself by changing the Assumptions. Because ...

What is the baseline year from which the temperature change is measured?
The temperature change you see on the right-hand side of En-ROADS is the change in global temperature from pre-industrial times (averaging over the period 1...

Does En-ROADS account for inflation in the future?
Yes, En-ROADS incorporates inflation through using constant year purchasing power parity (PPP) data for GDP, which bakes in inflation. Therefore we can assu...

Why are all renewable energy sources grouped together in En-ROADS?
Renewable energy sources (solar, wind, hydro, geothermal, and marine energy) are grouped together in the online En-ROADS simulator, although wind, solar, ge...

Does En-ROADS account for changes due to COVID-19?
We have not adjusted En-ROADS in response to climate and energy impacts due to the COVID-19 coronavirus pandemic.  While the impacts of the coronavirus ...

Does En-ROADS account for the economic impact of climate change?
Yes, En-ROADS enables users to simulate the economic impact of climate change, specifically the reduction in average GDP per capita due to temperature rise....

What is the mathematical formulation behind the economic impact of climate change in En-ROADS?
The economic impact of climate change is often quantified as a fractional reduction in global or regional annual income, GDP, or GDP growth. This fractional...

Why doesn’t En-ROADS fully match the damage functions from scientific literature if I use the preset damage functions?
The mathematical formulation of the damage function in En-ROADS is different from the ones used in the literature, yet the En-ROADS function can be calibrat...
