What is Grey to Green?

The Grey to Green Conference features the latest research, industry developments, and end-users to share, learn and network over three full days of programming and training - with a dash of inspiring speakers and case studies.

About the Conference

Grey to Green is coming to the U.S with two excellent opportunities to engage local markets in the the Minneapolis-St. Paul region and the Washington D.C region. The conferences will take place in the Twin Cities on September 30-October 1 and will travel to the Washington D.C. area on October 29-30. Grey to Green will highlight new policy, design practices, and innovative products in the green infrastructure sector. Our goal is to help inform the current policy debate by making the case for a rapid and significant increase in green infrastructure investment, a trend that’s occurring worldwide.

This year, Grey to Green will highlight the economic impacts of climate change adaptation such as flooding and the urban heat island. Flooding affects both the individual in terms of health and well being and has significant economic impacts for society. These issues will continue to get worse as climate change progresses, but green infrastructure can help. Our cities are experiencing a greater frequency of heat waves and higher average temperatures. This has negative economic, social and healthy impacts. Quantifying green infrastructure performance helps us understand the myriad benefits of green infrastructure and determine their economic value, a crucial step in expanding public and private investments the use of these technologies.

The Grey to Green Conference features the latest research, industry developments, and end-users to share, learn and network. Attend concurrent sessions and networking events with industry leaders, attend training courses and workshops, and participate in tours across the GTA.

Continuing Education: Grey to Green Toronto will be pending approval for various continuing education credits following agenda selection. As always, the Grey to Green Conferences and Events are approved for Green Roof Professional credits.

What is Green Infrastructure? 

Green infrastructure consists of both natural systems such as forests and wetlands, as well as vegetative technologies like green roofs and green walls, and the products designed to support growth such as engineered soils, cisterns and irrigation systems.

Green infrastructure technologies also include bioswales, meadows, engineered wetlands, planting beds, turf and permeable pavements. All of these living green infrastructure elements create a system in your community that greatly support quality of life.

is green infrastructure important? 

There are many economic, social and environmental benefits of green infrastructure including job creation, stormwater management, support for biodiversity, reduced air and noise pollution, and improved marketability of buildings.
