Reducing CO2 with Smart LED Lighting and City Data
July 17, 2017
Appearing during the “Local 2030: Hub for Sustainability Solutions” Special Event at the UN Headquarters in New York this week, Philips Lighting will highlight the need for high-calibre data to understand the value of LED systems and how a new partnership between Philips Lighting and the World Council on City Data (WCCD) is addressing this need in collaboration with cities around the world.
A new report jointly produced by Philips Lighting and the WCCD reveals that the city of Los Angeles made energy savings of 63 percent in 2016 by implementing such a system, generating cost savings of $9 million and reducing its annual greenhouse gas emissions associated with public lighting by 47,000 metric tons. This is equivalent to the greenhouse gas emissions from almost 10,000 passenger vehicles driven for one year.
Philips Lighting says that if cities around the world adopted such systems, they could make vast reductions in their annual emissions and expenditure on electricity.
The report says that better quality lighting could also bring benefits such as reduced crime rates and improved citizen perceptions of safety, with Los Angeles observing a 10.5 percent drop in crime rates for offenses such as vehicle theft, burglary and vandalism in the first two years of its LED conversion program.
Other benefits of connected LED street lighting cited by the report include improvements in traffic safety for all road users, city attractiveness and economic strength. By producing these benefits over and above emission reductions, smart LED lighting will also make a major contribution to meeting the UN Sustainable Development Goals, a globally-agreed set of targets for moving to a sustainable future by 2030.
“City authorities face complex and challenging choices concerning infrastructure, balancing the need to maintain existing services while investing in improvements, managing population growth and enhancing sustainability – all within tight budget constraints,” said Harry Verhaar, Head of Global Public and Government Affairs, Philips Lighting.
The operation and maintenance of street lighting is a major cost that contributes to these challenges for local authorities. But new technologies are transforming the way cities can deliver, operate and maintain public lighting in a way that can generate a wide range of benefits to the local authorities and the communities they serve. The challenge is building the investment case to enable them to implement this technology in the first place.
“We are calling for all cities to adopt 100 percent LED street lights by 2025. Of approximately 300 million streetlights across the world, only about one in ten are energy-efficient LEDs, and just 2 percent are connected. Combining energy-efficient lighting with connected system management can deliver energy savings of up to 80 percent – which would make a significant dent in our climate change targets,” Verhaar added.
Lighting currently accounts for 15 percent of global electricity consumption, but with a universal switch to LEDs, lighting’s share of power consumption would fall to just 8 percent.
Stumbling blocks to the adoption of public sector smart technology projects include financing projects upfront, particularly with squeezed local authority budgets.
The report presents a measurement framework that can monitor and evaluate city-level impacts of smart and connected lighting investments, arguing that the adoption of standardized city data such as used in Los Angeles will help to inform infrastructure investment and decision-making and build the investment case for smart technology projects.
The WCCD has been mapping its ISO 37120 standard to the 17 themes of the United Nations Sustainable Development Goals, in order to support cities in taking a leadership position to address these goals.
“The ISO 37120 standard that the WCCD is implementing with cities globally defines a comprehensive set of 100 standardized indicators that enables any city, of any size, to assess their performance and measure progress over time in a way that can be accurately benchmarked and compared with other cities,” explained Dr Patricia McCarney, President & CEO, WCCD.
This data can clearly quantify how investments can improve infrastructure service levels across a city and deliver benefits to its inhabitants. The benefits of smart infrastructure solutions cover financial, economic, social and environmental spheres so this data-driven approach is particularly useful for evaluating these.
“Mayors and city leaders throughout the world are taking on key global issues from climate change to poverty, migration, trade and investment, embodied in the SDGs. High calibre city data that is globally standardized is critical for city leaders to monitor progress on these global goals, benchmark performance and learn lessons from all international regions,” McCarney concluded.
