1) International Policy Movement of Green Roofs
This research traces the policy mobility of green roofs creating a timeline and overarching map. This presentation focuses on the policy mobility of direct and indirect green roof policies implemented, predominantly, at city scale. Policy mobility is the circulation and assemblage of a policy through knowledge exchange and transfer of previous policies adopted in other places. The findings illustrate that the first modern policy originated in Dusseldorf in 1979, before spreading across Germanic cities as well as, unexpectedly, Guangzhou in China in 1997. At the turn of the century, policy adoption moved to North America, as well as Asian cities, for example Tokyo and Singapore. Tracing policy mobility in a linear transfer becomes complex after 2002 due to rapid expansion in implementation within cities in Europe, USA and Asia. More recently, policy implementation is occurring in South America in cities such as Buenos Aires, Recife and Cordoba. The key facilitators of this policy mobility were found to be associations, networks, prominent individuals, and municipalities. Their impact on the narrative is significant but specific local factors such as planning cultures and systems, climatic conditions, and urban issues are also large influences. Implementation must take account specific urban issues, for example stormwater flooding, air quality, urban heat island effect, decreasing biodiversity, energy efficiency and lack of communal space due to a densifying city.

2) DEP-Funded Green Roof Success Stories
The generosity of the DEP's Green Infrastructure Grant Program has enabled many green roof projects to come to fruition in New York City. A portion of our projects at Highview Creations have been possible because of this grant funding. Our team of designers and installers have become experts in these types of projects, and we have learned the intricacies of the grant process over time. There is significant amount of information and learning required to go through the DEP funding process. Building owners need to be made aware of certain legally binding documents, and the green roofs have to be maintained for 20 years. This type of client management has become a great skill set for our company as we navigate the DEP grant territory. With regards to design, our team has also learned the most cost-effective and creative ways to work within the parameters of the DEP grant guidelines. While many may see limitations with extensive, low-cost green roofs, we try to use native flora whenever possible to make each project uniquely New York.

3) Greener Cities – London, Europe and Beyond
In 2018 the European Federation of Green Roof and Wall Associations in partnership with will undertake a review of the current London approach to green roofs and walls. Whilst the report will be anchored in celebrating and evaluating the success of the policy in London, it will also aim to provide a comprehensive review of policies throughout cities in Europe. In so doing the report will aim to provide an understanding in the various approaches to green roof and wall policies to help other cities in Europe currently without policy to adopt and adapt approaches for the specific requirements.
This presentation will outline the success of London and how this success is has the potential to influence other jurisdictions in the UK and Europe. It will also present a review of city policies and city aspirations within Europe. Furthermore it will also look to highlight innovative approaches in cities
