C40 and Tokyo highlight city actions on building energy efficiency in new report

Zoe Sprigings, C40 Network Manager of Energy Efficiency

Buildings shape the iconic skylines of our global megacities. For many of these cities, buildings also hold the key to tackling climate change. Building energy use is one of the leading sources of greenhouse gas (GHG) emissions in cities – almost half of the emissions from member cities of the C40 come from energy consumed in buildings.

Tokyo co-leads the C40 Private Building Efficiency Network, a group of cities committed not only to tackling energy efficiency in their own buildings, but also to collaborating with others so they can take faster action, and have more impact. These cities are already pioneering new policies for their buildings, often moving quicker than nations or regions. Despite this, there is an evidence gap on what is happening at the city level. It was through discussions with fellow members of the Network that Tokyo saw the need to capture best practice from cities around the world, and share it.

The result, Urban Efficiency: A global survey of building energy efficiency policies in cities [Updated May 2015], is a compelling example of C40 cities’ leadership and collaboration, sharing information to support each other’s carbon reduction efforts.

For a city just starting out in energy efficiency, this report offers a menu of possibilities. For a city in the midst of implementation, it’s a guide to finding solutions to common challenges. For a city that has just completed a programme, it’s inspiration for where to go next.

In fact, cities in the C40 Private Building Efficiency Network have already indicated how the report will be useful in furthering their own building efficiency efforts. 

 “The Urban Efficiency case studies focused on particular policies and programmes in ten C40 cities will be a critical reference for us as we develop our Energy Efficiency Master Plan. Incorporating lessons from our peer cities allows us to move a step ahead in the planning process.” Nik Midlam, City of Sydney

“This research will be particularly useful as Toronto considers approaches for energy performance data reporting and benchmarking. Urban Efficiency details how cities around the world have pursued similar efforts with great success, providing a solid foundation for us to build upon.” Mark Bekkering, City of Toronto
