PhD requirements in Environmental Management/Policy

[ESColumbiaAspirant]

Hi,

 I am looking to apply for environmental policy PhD for the fall 2017 intake. I have an undergrad in economics from India and an MSc. in environmental management from UK. I have 3 years of work experience but only a year of that is in environmental research, other 2 years of work ex is in finance. 

I will be appearing for my GRE in September, though I currently score between 300-320 in my mocks. I wanted to know which programs should I apply to with my background? I found Ivy League colleges like SIPA columbia, FES Yale and Duke's PhD but I am skeptical of my ability to get admission in them. Are there any other PhD programs focusing on the management and/or policy side of the environment?
