Challenges and Opportunities in the Voluntary Carbon Markets

October 7, 2024
Author(s)
Pamela M. Chu, Noah Last, Buddhika Hapuwatte, Clayton Porkorny, Vishal Agrawal
With the increasing need to eliminate carbon dioxide emissions, the voluntary carbon market (VCM) provides a platform to help organizations reach net-zero emission goals through the purchase of carbon offsets. Carbon offsets provide a means to compensate

Workshop on Decarbonization: A Gap Analysis of LCA Standards for Industry

September 20, 2024
Author(s)
Noah Last, Joshua D. Kneifel, Amy Costello, Catherine Houska, Katherine Morris
ASTM International's committee on sustainability (E60), in collaboration with the National Institute of Standards and Technology (NIST), hosted the virtual "Workshop on Decarbonization: A Gap Analysis of LCA Standards for Industry" on October 10-11, 2023

Random and systematic uncertainty in ship-based seawater carbonate chemistry observations

September 8, 2024
Author(s)
Brendan Carter, Jonathan Sharp, Maribel I. Garcia-Ibanez, Ryan J. Woosley, Michael Fong, Marta Alvarez, Leticia Barbero, Simon Clegg, Regina Easley, Andrea Fassbender, Xinyu Li, Katelyn Schockman, Zhaohui Aleck Wang, Andrew Dickson
Seawater carbonate chemistry observations are increasingly necessary to study a broad array of oceanographic challenges such as ocean acidification, carbon inventory tracking, and assessment of marine carbon dioxide removal strategies. As a result, efforts

NIST Greenhouse Gas Measurements Program: A Decade of Critical Accomplishments

June 5, 2024
Author(s)
James Whetstone, Tamae Wong, Hratch Semerjian
At COP 21 (Paris), there was general agreement that programs to reduce greenhouse gas emissions and mitigate atmospheric warming will require an understanding of existing emissions as well as programs to monitor, report, and verify emissions from a broad

Life-Cycle Analysis Datasets for Regionalized Plastic Pathways

February 1, 2024
Author(s)
Taemin Kim, Pahola Benavides, Joshua Kneifel, Kate Beers, Zifeng Lu, Troy Hawkins
The carbon intensity (CI) of producing five different resins – polyethylene terephthalate (PET), high-density polyethylene (HDPE), low-density polyethylene (LDPE), polypropylene (PP), and polyvinyl chloride (PVC) – in four different international regions –

Recommendations from the Ocean Carbonate System Intercomparison Forum: Quantifying and reducing uncertainties in the calculations of carbonate system equilibrium in the oceans

December 14, 2023
Author(s)
Brendan Carter, Jonathan Sharp, Andrew Dickson, Marta Alvarez, Michael Fong, Maribel Garcia-Ibanez, Ryan Woosley, Takeshita Yuichiro, Leticia Barbero, Robert Byrne, Wei-Jun Cai, Melissa Chierici, Simon Clegg, Regina Easley, Andrea Fassbender, Kalla Fleger, Xinyu Li, Macarena Martin-Mayor, Katelyn Schockman, Aleck Wang Zhaohui
The ocean carbonate system is critical to monitor because it plays a major role in regulating Earth's climate and marine ecosystems. It is monitored using a variety of measurements, and it is commonly understood that all major components of the seawater

Life Cycle Environmental Impacts of Plastics: A Review

March 1, 2022
Author(s)
Paul Rikhter, Ilayda Dinc, Yirui Zhang, Ted Jiang, Bobby Miyashiro, Shelby Walsh, Ruoyu Wang, Yvonne Dinh, Sangwon Suh, Joshua D. Kneifel
Global production and consumption of plastics and its deposition in the environment are growing rapidly, while their life-cycle impacts to the environment are yet to be fully understood. This study reviews the existing literature with the goal of

Silicone tube humidity generator

February 16, 2022
Author(s)
Robert F. Berg, Nicola Chiodo, Eric Georgin
We describe the model and construction of a two-flow (or divided-flow) humidity generator, developed at LNE-CNAM, that uses mass flow controllers to mix a stream of dry gas with a stream of humid gas saturated at 28 °C. It can generate a wide range of

Building for Environmental and Economic Sustainability (BEES) Online 2.1 Technical Manual

September 20, 2021
Author(s)
Joshua D. Kneifel, Anne Landfield Greig, Priya Lavappa, Brian Polidoro
Building stakeholders need practical metrics, data, and tools to support decisions related to sustainable building product selection. The Engineering Laboratory of the National Institute of Standards and Technology (NIST) has addressed this national need
