The Path to Drawdown: High-Performance Glass

Buildings and construction account for 38% of the total global CO2 emissions and 35% of total energy use. And much of the energy-use in buildings is the result of heating and air-conditioning, lighting, information and communications systems, security and access systems, fire alarms, elevators, appliances, and indirectly through plumbing.

In most buildings, some of the energy used in heating or cooling the interior is wasted through windows. Windows, even when closed, are much less efficient than insulated walls at keeping room temperature in and outside temperature out - by a factor of ten or more.

High-performance glass solves this problem by replacing conventional plain glass. High-performance glass uses any of several mature status glass technologies that can reduce heat flow across the glass including multiple layers, low-emissivity glass, tinted glass, and vacuum glazing.

High-performance glass is already widely adopted in wealthy countries. In the rest of the world, a faster and wider installation of high-performance glass can help reduce a substantial amount of GHG emissions between now and 2050:

  • <::marker> In 2018, 5 billion square meters of high-performance glass was installed in residential buildings, and 130 million sq meters in commercial buildings
  • <::marker> By 2050, 13.7 billion sq meters should be installed in residential buildings and 7.5 billion sq meters in commercial buildings

If this scale can be achieved by 2050, high-performance glass can avoid 12.6 gigatons of emissions and save $3.9 trillion in energy costs over building lifetimes for an installation cost of $10.8 trillion.

What We Want to See Improve

Track Emissions Metrics

As of now, Apogee doesn’t track and report key sustainability metrics, like the amount of GHG emissions. To let climate-conscious investors evaluate Apogee’s carbon footprint, we urge them to start tracking and reporting their emissions in an annual sustainability report.

Reduce GHG Emissions

In their sustainability commitments, Apogee focuses on energy efficiency and recycling. While we commend these commitments, these commitments don’t directly address the biggest problem of our era - climate change. We want Apogee to set explicit targets for reducing their GHG emissions within a precise time frame.

Push Suppliers to Reduce Emissions

Apogee’s Supplier Code of Conduct (p. 26-27) includes expectations for suppliers to adhere to environmental laws and regulations. These focus on the handling and disposal of hazardous material, water and air pollution. While we applaud detailed guidelines for suppliers, we would like to see Apogee pressing their suppliers to reduce their GHG emissions so as to lower the carbon footprint of their entire supply chain.
