We're working to transform how we light our world. Lighting accounts for nearly 6% of global CO2 greenhouse gas emissions, or 1,900 million tons of CO2 per year— the equivalent of CO2 emissions from 70% of the world’s passenger vehicles. By making lighting more energy efficient we can make a significant dent in carbon emissions.
Light-emitting diode (LED) lamps can cut CO2 emissions by 50–70%, with additional savings achievable with flexible smart controls. LED outdoor lighting also reduces costs, enhances public safety, minimizes light pollution and makes public spaces friendlier at night. The potential for LED technology is unprecedented: some industry experts predict that within 10 years LED lights, both indoor and outdoor, could deliver more environmental and economic benefits than any other clean technology including renewable power.
In 2012 we conducted the LightSavers project - a global trial of LED lamps in 12 large cities around the globe to evaluate how the latest LED products performed and are perceived by the public. The results were presented in a report highlighting how LED technology is ready for full scale rollout around the world. We also published a technical summary for lighting managers as well as a series of city specific reports.
The same year, The Climate Group called for all new street lighting to be LED (or as efficient) by 2015, and all street lighting to be LEDs (or as efficient) by 2020.
Then at Climate Week NYC 2015, we called on every single city and utility around the world to schedule the switch of their street lighting to LED by 2025, with the launch of our new major global campaign LED = Lower Emissions Delivered and a new report, The Big Switch: Why it's time to scale up LED street lighting. Following our Consultations, the report reveals that while technological barriers for adoption have now been overcome, in the run-up to COP21, cities want more support from government and financial institutions to refine business models and financing options to help make the switch.

Many cities have announced major upgrades to LED lighting, but it is clear the vast majority have still yet to make the move. As a result in 2014 we entered the second phase of the LED-scale up project and announced the launch of a consultation process supported by our lead Partner Philips Lighting, to identify remaining regional barriers to adoption of LEDs and accelerate the transition to energy efficient lighting around the world.
We have organized a series of events and workshops around the world convening key regional stakeholders and municipalities to discuss important topics crucial for LEDs scale up in each of the visited region. A common challenge for cities is a need for independent support to city staff as they seek to assess the different business case options for their unique city circumstances, from both the technical and financial standpoints. Such capacity support in the early stages of business case review could significantly help reduce the number of technical and funding options during the tendering process - and help speed up procurement.
As a result of these and other region-specific challenges we are extending the consultation workshops into 2016.

The energy saving potential of LED lighting has been proven over extended time periods in cities around the globe, and as a result LEDs are now predominantly the first choice for cities when upgrading their lighting infrastructure. Our LED program systematically evaluates projects around the world. See latest news and relevant links and case studies below .

This section provides links to examples of tools that have been recently developed to support cities and municipalities in their planning for LED lighting upgrades.
Beyond the immediate and calculable energy savings that LEDs can provide, there are many other factors that can influence the decisions of city managers around current and future lighting needs of cities.
Upgrade decisions can be influenced by available financing, remaining lifetime of existing fittings and whether needs can be met by either retrofitting luminaires, replacing lighting/poles, upgrading aging infrastructure and addressing options for future proofing fittings.
Below is an open toolkit list for reference. To suggest links, please do not hesitate to contact us.
A comprehensive archive of information on how LEDs work, their energy efficiency, luminous efficiency and color quality.
The DOE shares detailed reports that include analysis of data collected, projected energy savings, economic analyses and user feedback. Report briefs summarize key findings in a quick-scan format.
Developed by the Scottish Futures Trust (SFT) and supported by the Scottish Government, the toolkit allows councils to input their current street lighting data which in turn calculates what the reduced electricity usage would be if they changed to new, energy-efficient LED lighting. The toolkit also calculates what level of investment is required by the council and the payback period of the loan.
