The Path to Drawdown: LEDs

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

There are many environmental advantages to LED lighting. Its efficiency in turning energy into light, rather than heat, helps reduce electricity consumption and air-conditioning loads. For people without access to ample energy, LEDs can be powered with small solar cells, replacing 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.

As Project Drawdown projects, if LED lighting becomes widely used in the residential and commercial lighting market, it can help 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 grow rapidly:

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

About

Amtech Systems, Inc. (stock ticker: ASYS) is a supplier of semiconductor equipment and consumables serving mobile, computing, industrial, automotive, telecom, medical, and other industries. Headquartered in Tempe, Arizona, they primarily sell their products in Asia, North America, and Europe.

ASYS's Role in Drawdown

Amtech Systems has two business segments: Semiconductors and silicon carbide & LEDs. The first segment manufactures semiconductors, which are then used in industrial, commercial and residential lighting. 

The second segment provides solutions with applications in silicon wafers for semiconductor products, LED and power device applications, sapphire substrates for LED lighting and mobile devices, various glass and silica components for 3D image transmission, etc.

Their semiconductor and silicon carbide & LED segments accounted for 84% and 15.9% of Amtech’s total 2020 revenue, respectively.

ASYS: What We Like

We’ll update this section once Amtech makes sustainability information available.

ASYS: What We Want to See Improve

Disclose Sustainability Metrics


As of now, Amtech provides no information related to sustainability or environmental impact of their operations. We want to see this change. Amtech should track and report key sustainability metrics like their direct and indirect GHG emissions, emissions avoided, and energy consumption by source in an annual sustainability report so that investors and stakeholders can transparently assess Amtech’s carbon and environmental footprint.

Set Emissions Reduction Targets


Once these metrics are tracked and disclosed, Amtech should set targets for reducing emissions. These targets should be clear, quantitative, and scientifically-driven so as to conform to the global goal of staying below 1.5°C of global warming.

Enhance Supplier Transparency


There’s very little transparency regarding Amtech’s suppliers. We would like them to disclose how many suppliers they work with, what regions they’re located, and eventually the amount of emissions these suppliers account for.
