Retrofit diesel engines with black carbon filters as a project cost by C Moore/M MacCracken
Aug 5, 2014
This proposal has obvious greenhouse gas emissions benefits, and we feel that this proposal should advance to the semi-finalist round. We would like to see it put into action. As such, we have a number of specific suggestions that could improve your proposal: 1) We think some quantification of cost-effectiveness would be very beneficial. 2) You could do more to describe the rulemaking process that would lead to this action. For example, what steps does EPA have to take to require these filters? Has this already happened (we thought of the CAFE standards). If so, what parallels could you draw 3) We feel that the author should address the political landscape that would affect this proposal. For instance, you mention that retrofitting a single vehicle may be expensive in the context of the individual vehicle, and so we wondered how financially feasible the entire proposal would be. Who would object? How would you counter these objections? In essence, the idea is fundamentally sound, and digging deeper on the details will make this proposal much more compelling. Good luck!

Sounds good, though it could be extended to all nations, especially important in developing countries where many autos emit BC due to less rigor in maintaining vehicle engines and lack of access to qualified mechanics.
In your response about who would take these actions you suggest the President of the US. But, that isn't how federal laws are promulgated.
"Federal law. Federal law originates with the Constitution, which gives Congress the power to enact statutes for certain limited purposes like regulating interstate commerce. The United States Code is the official compilation and codification of the general and permanent federal statutes." https://en.wikipedia.org/wiki/Law_of_the_United_States
"Federal laws generally apply to people living in the United States and its territories. Congress creates and passes bills. The President then signs those bills into law. Federal courts may review these laws and strike them down if they think they do not agree with the U.S. Constitution." https://www.usa.gov/how-laws-are-made
