CO2 and air pollution can be reduced significantly by improving
cities’ transportation systems, but quantifying those reductions
can be difficult. This article originally appeared on Embarq’s
blog The City Fix. As transportation demand continues to rise at
unprecedented rates, the need to compare alternative transport
policies and their impacts on both CO2 emissions and local air
pollution is becoming more and more critical. However, the
challenge of quantifying these impacts has often hindered
transparent and well-informed decision making. To help address
this barrier, EMBARQ/WRI has just released a new publication
entitled “Measuring the Invisible: Quantifying Emissions
Reductions from Transport Solutions”. The new report is composed
of a series of case studies that examine how three developing
country cities (Queretaro, Mexico, Porto Alegre, Brazil, and
Hanoi, Vietnam) can quantify emissions reductions from transport
interventions. Importantly, we found that in each case, there is
a large potential to redu
