The Path to Drawdown: LEDs

Light-emitting diodes (LEDs) were invented in 1994 as high-brightness, high-efficiency light bulbs. They work like solar panels in reverse, by converting electrons to photons instead of the other way around. For the same amount of light, LEDs use 90% less energy than incandescent bulbs, and half as much as compact fluorescents. While other lighting technologies convert energy into heat (and wasting most of it), LEDs turn 80% of their energy use into light.

LED lighting has many environmental advantages. Its efficiency in converting energy into light, rather than heat, helps reduce electricity consumption and air-conditioning usage. For people without access to ample energy, LEDs can be powered with small solar panels and can replace expensive kerosene lamps and their noxious fumes and emissions. Where LEDs are used in streetlights, they can save up to 70% of energy and significantly reduce maintenance costs.

Project Drawdown projects that if LEDs become widely used in the residential and commercial lighting market, they can avoid between 10.2 - 10.8 gigatons of CO2 emissions in residences, and between 5.9 - 6.7 gigatons in commercial buildings. To achieve this, the global market share of LEDs needs to scale rapidly:

  • <::marker> In 2018, LED lighting comprised 3% of the total commercial lighting market and 2% of the residential lighting market;
  • <::marker> By 2050, LEDs should account for 95% and 90% of the residential and commercial markets, respectively;
  • <::marker> That’s 12.82% CAGR for residential LED, and 11.21% CAGR for commercial LED lighting between 2018 - 2050.

What We Want to See Improve

Achieve Profitability

Since 2011, SemiLEDs has suffered losses (p. 3) because of under-utilization of their manufacturing capacity for their LED chips. In response, they’ve moved and consolidated their LED packaging facility and managed costs and expenses. We eagerly wait for SemiLEDs to bounce back from these predicaments and achieve profitability as soon as possible.

Publish ESG Reports

As of now, SemiLEDs has no information on their sustainability commitments or direct or indirect GHG emissions. To help climate-concerned investors assess SemiLEDs’ carbon footprint, we want to see them publish an annual ESG report with metrics including scope 1, 2 and 3 emissions and GHG emissions avoided.

Enhance Supply Chain Transparency

SemiLEDs purchases raw materials and components from a wide range of suppliers (p. 3) around the world, and has two or more suppliers for a majority of those raw materials. For the purposes of evaluating the carbon footprint of their suppliers, we would like to see SemiLEDs enhance the transparency about their suppliers and their GHG emissions.
