Of all the issues of serious concern to Nashvillians:
Crime
Education
Jobs
Traffic
Taxes
Immigration
Corporate demands for taxpayer money
Zoning
and 
his own statements highlighting the issues heretofore of biggest concern:
I will continue to promote neighborhoods and community. The greatest challenge I see for Nashville is preserving our sense of community.          
It is imperative that Metro exercise fiscal responsibility.        
As Mayor, I will demand open and ethical government. Without the trust of the people, government lacks all legitimacy.        
Educating our children is our community's most important responsibility.         
Issues of planning and zoning and ensuring public safety will be high priorities under my administration.
he steps over all of those 
important issues and decides to make sustainability a cornerstone of his campaign for mayor.
“I want to  build upon the traditions established by Mayors Bredesen and Purcell and  establish sustainable policies that protect our environment and natural  resources, lessen our dependence on fossil fuels and foreign energy sources, and  engage the entrepreneurial spirit of our business community.” said  [David] Briley.  “I want to be known as Nashville’s ‘Green Mayor.’”
Fellow mayoral candidate 
Dave Pelton has some serious credentials in this area as founder of 
Clean Cities of Middle Tennessee. I've seen the guy's truck--a rolling billboard for alternative fuels. It could be interesting to see the Dave's go head to head over who is greener.
I want a clean planet too but I want more for it to be a physically safe place to be. A place where the education children were promised is provided. A place where neighborhoods are protected from encroachment by business and honor is restored to government service.  Maybe the greenest part of this campaign is thinking that this should be the driving issue.
I can't find a link to the press release on David's website (maybe it's on the Spanish side--it's a joke folks!).

 BRILEY TO ESTABLISH  
 MAYOR’S OFFICE OF  SUSTAINABILITY
   
 I want to be  Nashville’s ‘Green Mayor’
   
 NASHVILLE, Feb. 15  -- Mayoral candidate and Councilman-At-Large David Briley today announced a  seven-point plan to address the significant environmental issues that confront  Nashville and many other American cities.  Briley made his  announcement standing on the public square in front of the Davidson County  Courthouse.  The public square is the city’s first green structure,  as defined by Leadership in Energy and Environmental Design (LEED)  standards.
    
 “I want to build  upon the traditions established by Mayors Bredesen and Purcell and establish  sustainable policies that protect our environment and natural resources, lessen  our dependence on fossil fuels and foreign energy sources, and engage the  entrepreneurial spirit of our business community.” said Briley.  “I  want to be known as Nashville’s ‘Green Mayor.’”
   
 Earlier this week,  Briley introduced local legislation requiring Metro-owned buildings to meet  LEED-certified sustainable building design requirements – a money-saving method  of increasing the energy efficiency of buildings and lessening their  environmental impact.  Briley also filed legislation calling for  the expansion of curbside recycling services to Nashville’s General Services  District. “This is a start, but we have miles to go,” Briley stated as he  introduced a series of environmental initiatives ranging from the large-scale  creation of a new Mayor’s Office of Sustainability to smaller initiatives  including mandatory compact fluorescent light bulbs in Metro-owned  facilities.
   
 Briley’s proposed  initiatives include:
 
 
1)   Establishing of a Mayor's Office of Sustainability. Create a  Mayoral Office to coordinate public and private sector initiatives on  environmental improvement, assess methods of lowering carbon emissions, expand  environmental education opportunities in public schools and elsewhere, address  environmental racism and injustice, and establish a  standardized measure of environmental quality with reports provided on an annual  basis. 
 
2) Implement  green building standards for public and private construction. Require  Metro-owned buildings to meet environmental design criteria, providing financial  savings by virtue of reduced energy costs and demonstrating good environmental  stewardship. Similar objectives should be encouraged in the private sector  through planning and zoning incentives, including density bonuses and “fast  track” approval of green construction. These initiatives will be offered at  virtually no cost to the city and result in a cleaner, healthier, more efficient  Nashville.
    
 3) Establish a  dedicated fund for open space acquisition. Dedicate .01¢ from  the existing property tax levy toward open space acquisition, providing a  permanent and flexible means of creating open spaces in our growing city.   The dedication of .01¢ will generate over $20 million annually at an  average annual cost of $5 per household.
 
4) Expand  curbside recycling to General Services District. Expand subscription  curbside recycling -- currently limited to the Urban Services District -- to all  of Nashville. By providing recycling opportunities to the General Services  District (initially on a subscription basis through a volunteer program), we  encourage all Nashvillians to participate in our shared  responsibilities.
  
5) Encourage  use of hybrid, low-emission, and alternative fuel vehicles.  Establish  a Metro fleet of hybrid vehicles, and encourage the public’s use of hybrid, low  emission and/or alternative fuel vehicles with incentives, including free or  priority parking in Metro facilities and at parking meters, and encourage state  legislation expanding the eligibility for HOV lanes to hybrid  vehicles.
   
 6) Eliminate the  bias toward asphalt and concrete. Require the  planting of trees and other greenery in rights-of-way and public property, where  Metro has historically opted to pave over soil. Our medians and intersection  islands should be green. Our sidewalk regulations should be amended to allow  installation of more grade-level trees. Metro government should also plant at  least 1,000 trees every year as a means of re-establishing our vanishing tree  canopy.
   
 7) Establish  emissions reduction target. Establish a year  2014 emissions reduction target for Davidson County of 10% below the emissions  levels of 2000, significantly reducing greenhouse gas emissions in Nashville,  and demonstrating that choices made by local governments and local communities  can make a significant impact in global efforts to reduce carbon  emissions.
 
Local architects are praising  Briley's commitment to the project.  "David's initiative calls for setting  standards and guidelines that will ensure more local control of development and  its impact on our environment," said Alan Hayes, Architect and LEED  AP with Thomas, Miller and Partners. "Across the country, local governments are  embracing these types of programs and they have proved cost effective and  beneficial to the tax payers.   This is an innovative first step, not just for  David Briley, but for all Nashvillians."
