Abstract

Evaluating the climate and air quality impacts of short-lived pollutants

Highlights

The United Nations Framework Convention on Climate Change (UNFCCC) requires climate policies to “be costeffective so as to ensure global benefits at the lowest possible cost” and that “policies and measures should . . . be comprehensive . . . [and] . . . cover all relevant sources, sinks and reservoirs”
The ECLIPSE emission data set was created with the GAINS (Greenhouse gas–Air pollution Interactions and Synergies; http://www.iiasa.ac.at/web/home/research/ researchPrograms/GAINS.en.html) model (Amann et al, 2011), which provides emissions of long-lived greenhouse www.atmos-chem-phys.net/15/10529/2015/
The model relies on exogenous projections of energy use, industrial production, and agricultural activity (ECLIPSE scenarios draw on IEA, 2012, for energy and Alexandros and Bruinsma, 2012, for agriculture) for which it distinguishes all key emission sources and control measures

Summary

Introduction

The United Nations Framework Convention on Climate Change (UNFCCC) requires climate policies to “be costeffective so as to ensure global benefits at the lowest possible cost” and that “policies and measures should . . . be comprehensive . . . [and] . . . cover all relevant sources, sinks and reservoirs”. Cover all relevant sources, sinks and reservoirs” This was made operational by the Kyoto Protocol, which sets limits on emissions of six different greenhouse gases (GHGs), or groups of GHGs – carbon dioxide (CO2), CH4, nitrous oxide (N2O), perfluorocarbons (PFCs), hydrofluorocarbons (HFCs) and sulfur hexafluoride (SF6). These are often known as “the Kyoto gases” or the “Kyoto basket”. Other anthropogenic emissions capable of causing climate change are not covered by the Kyoto Protocol. Notably several short-lived components that give strong contributions to climate change that are excluded from existing climate agreements
