Decarbonizing Industrial Supply Chain Energy (DISC-e)

The Decarbonizing Industrial Supply Chain Energy (DISC-e) program uses the collective power of large consumers to accelerate the market for low-carbon industrial commodities that use carbon-free energy.

The REBA Institute’s DISC-e program advances climate goals by tackling industrial sector emissions through the power of the private sector market. Industrial emissions are a primary driver of energy-related greenhouse gas (GHG) emissions growth, some of the most difficult emissions to address, and are critical to achieving a global zero-carbon energy system.

The DISC-e program organizes large consumers with Scope 3 GHG commitments to create demand-signals that reverberate down supply chains. Collectively, these companies can make a meaningful impact through a clear market signal for low-carbon industrial commodities.

Building demand for low-carbon Solar

Solar installations are expected to grow significantly over the upcoming decade. The DNV GL’s Energy Transition Outlook forecasts that new solar photovoltaic (PV) installations will triple by 2030, and with rapid growth comes increasing scrutiny of the carbon found in the solar supply chain. Although the energy produced by solar energy is free of emissions, the extraction of raw materials, sourcing, and manufacturing is not. The DISC-e Solar Supply Chain group will establish low-carbon norms before the market expands further and proactively navigate the challenge that the industry faces if it does not address its own supply chain.

Building demand for low-carbon Building Materials

Building materials are one of the largest sources of embodied carbon, half of which is related to the two largest individual industrial commodities, steel and concrete. Market action to procure lower-carbon building materials can lock-in significant carbon reductions for decades to come. As in other areas of the transition to a zero-carbon future, the private sector has an outsized leadership opportunity to accelerate the adoption of related tools, strategies, and policies across the sector through procurement activities.

Building demand for low-carbon Aluminum

Aluminum is a critical material for the technologies driving the clean energy transition, like PVs, electric vehicles, and batteries, and touches all major sectors of the modern economy. Momentum is growing to decarbonize this industrial commodity with a need and opportunity to align on a unified demand-side signal to the market for low-carbon aluminum. Unlike some of the other harder-to-abate industrial sectors, a large percentage of aluminum emissions come from electricity. As such, the transition to carbon-free energy for a substantial portion of aluminum emissions can be achieved with the technology that exists today.

REBA Institute Webinar – How companies can work to decarbonize steel in the renewable energy industry

August 26 at 12 PM ET

Steel is the world’s most widely used material, one of the biggest emitters of CO2 globally, and can account for up to 50% of a renewable energy producer’s supply chain emissions.

Join the REBA Institute’s Decarbonizing Industrial Supply Chains Energy (DISC-e) program and hear from SteelZero, United States Steel and Orsted to learn more about how companies can work to decarbonize the steel industry using collective action from demand side voices.

REBA Institute Webinar – EPEAT 101: Using ecolabels to decarbonize the solar industry

September 1 at 1 PM ET

Solar installations are expected to triple by 2030, and with rapid growth comes increasing scrutiny of the carbon found in the solar supply chain. While the energy produced by solar photovoltaic (PV) technology is free of emissions, the extraction of raw materials, sourcing, and manufacturing associated with the production of PV technology is not.

Companies can choose to address the emissions impact of their solar PV technology by using ecolabels that ensure products meet rigorous sustainability criteria. Ecolabels have a history of being used by program managers and institutional purchasers to showcase the sustainability of their projects and meet organizational net zero goals. As the world increasingly feels the impacts of climate change, the ability to credibly show how one’s choice of PV technology is reducing emissions is essential.

Join the REBA Institute and the Global Electronics Council (GEC) on a deep dive into EPEAT ecolabel. Hear from Debbie Graham-Clifford, Senior Manager at GEC and Dr. Parikhit Sinha, Senior Scientist of Sustainability Research at First Solar on the benefits and the registration process of EPEAT to help you on your ecolabel journey.

Past Events

REBA Institute Aluminum Workshop

June 16, 2021

This workshop is for large aluminum buyers with Scope 3 GHG commitments who want to a create zero-carbon demand-signal that will reverberate down their supply chains. Collectively, we believe that these companies can make a meaningful impact that is greater than the sum of individual efforts alone. This unified demand will send a clear signal that there is an urgent need and market for low-carbon aluminum.

REBA Connect: Virtual Member Summit Power of Corporate Engagement in Deep Decarbonization

May 13, 2021

Ambitious climate action commitments and attention to scope 3 emissions continues to increase across the private and public sectors. However, emissions from industrial commodities deep in an organization’s supply chain are difficult to address alone.  Learn how collective corporate action has the potential to move these markets and send a clear signal that there is an urgent need and market for zero-carbon industrial commodities.

How Companies Can Act Now to Procure Low-Carbon Building Materials

Recorded on February 23, 2021

Meghan Lewis, senior researcher at the Carbon Leadership Forum, Stacy Smedley, executive director at Building Transparency, and Katie Ross, senior sustainability program manager of real estate and facilities at Microsoft, discuss key principles of related corporate policy and how to leverage the free online tool, Embodied Carbon in Construction Calculator (EC3), to benchmark and reach embodied carbon reduction targets in new construction. Katie walks us through a real world example of how Microsoft has integrated corporate policy and the use of the EC3 tool into their operations.
