Aquaponics OPTI: sustainable food production
Sustainable food production depends on the recovery of water, energy, and nutrients from waste streams within existing supply chains. Greenhouse hydroponic systems (HYP) and recirculating aquaculture systems (RAS) are two intensive food production systems that in combined production as an aquaponics system (AP) can utilize fish wastes as fertilizers, while recycling water and energy to increase both systems’ sustainability and efficiency.

2021 Carbon Leadership Forum Material Baseline Report (version 2)
Carlisle, S., Waldman, B., Lewis, M., and Simonen, K. (2021). 2021 Carbon Leadership Forum Material Baseline Report, (version 2). Carbon Leadership Forum, University of Washington. Seattle, WA. July 2021. University of Washington ResearchWorks Archive.
Abstract
The building industry has an essential role to play in tackling climate change associated with building construction and materials manufacturing. Our present understanding of the importance of embodied carbon has been enabled by rigorous quantitative modeling that tracks carbon emissions across the full life of materials and products, using life cycle assessment (LCA). In recent years, the building industry has adopted LCA as the globally accepted method for evaluating and communicating environmental impacts, and applied these methods to the study of materials, products, and assemblies. LCA data and results are essential for guiding science-based efforts to decarbonize buildings and infrastructure.
The Carbon Leadership Forum is part of a broad movement working to drive down the embodied carbon of building materials and products by encouraging the disclosure of high-quality embodied carbon data by manufacturers. It is essential that designers, owners, and policymakers have access to verified, third-party reviewed and published data on building materials and products in order to facilitate procurement decisions, set decarbonization targets, and inform design. One tool for achieving this goal has been the collection and use of Environmental Product Declarations (EPDs) to inform decision-making.
The development of a material baseline originated in support of the Embodied Carbon in Construction Calculator (EC3). The EC3 Baseline was originally published in 2019. This document supersedes the baseline dated May 2020. The EC3 tool and its open-access database of digital EPDs are one source for accessing and evaluating available EPDs and the relative carbon impacts that they report. Such databases support designers, owners, and policymakers in selecting low-carbon products during procurement and design. These databases are dynamic, updated constantly as new products are added and upstream data on key processes, such as carbon intensity of regional electricity grids, are revised.

Abstract
The potential for meaningful climate impact through materials that serve as carbon sinks now gives such materials a clear advantage, with the potential to reverse the climate profile of buildings from a leading driver of carbon emissions to carbon reservoirs that can help reverse it.
Embodied Carbon Toolkit for Building Owners
Lewis, M., Huang, M., Simonen, K. (2021), “Embodied Carbon Toolkit for Building Owners”. Carbon Leadership Forum.
Abstract
Investors, developers, and public or private building owners and tenants are essential to reducing embodied carbon because they play an important role in spurring new projects and setting project requirements. Prioritizing carbon early in a project reduces cost and increases the range of strategies available, while signaling markets about the importance of low-carbon materials.
AIA-CLF Embodied Carbon Toolkit for Architects
Lewis, M., Huang, M., Carlisle, S. Simonen, K. (2021), AIA-CLF Embodied Carbon Toolkit for Architects, Carbon Leadership Forum and AIA National.
Abstract
The AIA-CLF Embodied Carbon Toolkit for Architects serves to provide architects an overview and the necessary steps to be taken to reduce embodied carbon in their projects. This resource is divided into three parts, introducing the necessary steps and resources to take in reducing embodied carbon. This resource intends to empower building designers by:
-introducing embodied carbon and discussing its significance in furthering architects’ influence in decarbonizing the building industry.
-providing an understanding of measuring embodied carbon through the methodology of a life cycle assessment.
-equipping them with strategies to reduce embodied carbon in their own projects.
-incorporating additional resources for implemented strategies and tools that this resource examines.
Buy Clean California Limits: A Proposed Methodology for Setting Industry-Average GWP Limits for Steel, Mineral Wool, and Flat Glass
Carlisle, S., Waldman, B., DeRousseau, M., Miller, L., Ciavola, B., Lewis, M., and Simonen, K. (2022).

Abstract
The Buy Clean California Act requires the California Department of General Services (DGS), in consultation with the California Air Resources Board, to establish maximum acceptable global warming potential (GWP) limits at industry-average for structural steel (hot-rolled sections, hollow structural sections, and plate), concrete reinforcing steel, flat glass, and mineral wool board insulation (heavy and light). DGS is directed to set these limits at the industry average using data from facility-specific environmental product declarations (EPDs) or industry-wide EPDs based on domestic production data.
In order for GWP limits to be effective they must be scientifically derived, transparent in their underlying methodology, and clear in scope and definition. Calculating industry-average values using EPDs, as required by the BCCA, is challenging: the quality and quantity of data available for calculating GWP limits varies by product type and is continually growing.
Developing an Embodied Carbon Policy Reduction Calculator

Abstract
A growing number of cities are committed to tackling the urgent challenge of their built environment carbon footprint through their policies and programs. 110 cities took the Cities Race to Zero Clean Construction pledges to reduce embodied emissions in their policies and programmes in 2021, and 40 leading cities are participating in the C40 Clean Construction programme and mayors are setting the direction of travel by signing the Clean Construction Declaration, which requires collective action to halve embodied emissions by 2030.
However, embodied carbon is a new policy area for many cities and the lack of city-level data on embodied carbon is a significant barrier for policymakers to gain political support and make informed decisions. The goal of developing an embodied carbon policy reduction calculator is to address these challenges by:
-Modeling the potential embodied carbon reduction of a selected number of policies to give cities the values they need to make informed decisions;
-Allowing for comparison of emissions reduction policies for embodied carbon by key target dates (2030 and 2050) to assess the largest opportunities for impact;
-Evaluating which policies may be required to meet embodied carbon reduction targets, such as those set by city or regional climate action plans; and
-Ultimately enabling cities to make the case for and adopt policies to reduce embodied carbon.
