LEDs are now massively produced in many markets, and competition among manufacturers is driving further innovation, wider product choices and lower prices.

Global electricity consumption by lighting in the Net Zero Scenario, 2010-2030


Lighting is one of the few technologies on track with the Net Zero Emissions by 2050 Scenario

The energy consumed for lighting and the resulting emissions both increased in 2021, following reduced commercial activity in 2020. However, with improving efficiency, lighting consumption is still expected to fall despite the growing amount of lighting being used in buildings.

2021 saw progress both in the deployment of light-emitting diodes (LEDs) and gains in lighting efficiency. While numerous countries began to phase out incandescent lamps more than ten years ago, many are now beginning to eliminate fluorescent lighting to make LEDs the main lighting technology. Over 50% of the global lighting market uses LED technology.

Although some advanced markets have introduced new regulations mandating the exclusive sale of high-efficacy (LED) lamps, progress in this area must be sustained to ensure that all countries sell predominantly LED technology by 2025, and with increasing efficiency to 2030, to align with the Net Zero Emissions by 2050 Scenario.
Our work on Lighting

The aims of the 4E TCP are to promote energy efficiency as the key to ensuring safe, reliable, affordable and sustainable energy systems. As an international platform for collaboration between governments, the 4E TCP provides policy guidance to its members and other governments concerning energy using equipment and systems. The 4E TCP prioritises technologies and applications with significant energy consumption and energy saving potential within the residential, commercial and industrial sectors (not including transport). To meet its aims, the 4E TCP harnesses the expertise of governments, industry, experts and other TCPs for joint research related to the development and deployment of energy efficient equipment.
