Acoustic Emission [PDF]

open access: yes, 2021
AbstractAcoustic emission (AE) is one of the most promising methods for structural health monitoring (SHM) of materials and structures. Because of its passive and non-invasive nature, it can be used during the operation of a structure and supply information that cannot be collected in real time through other techniques. It is based on the recording and

Monitoring global carbon emissions in 2022

open access: yesNature Reviews Earth & Environment, 2023
Global CO2 emissions for 2022 increased by 1.5% relative to 2021 (+7.9% and +2.0% relative to 2020 and 2019, respectively), reaching 36.1 GtCO2. These 2022 emissions consumed 13%–36% of the remaining carbon budget to limit warming to 1.5 °C, suggesting ...

More than 1000 rivers account for 80% of global riverine plastic emissions into the ocean

open access: yesScience Advances, 2021
More than 1000 rivers account for most plastic emissions, ranging from small urban drains to large rivers. Plastic waste increasingly accumulates in the marine environment, but data on the distribution and quantification of riverine sources required for ...

National contributions to climate change due to historical emissions of carbon dioxide, methane, and nitrous oxide since 1850

open access: yesScientific Data, 2023
Anthropogenic emissions of carbon dioxide (CO_2), methane (CH_4) and nitrous oxide (N_2O) have made significant contributions to global warming since the pre-industrial period and are therefore targeted in international climate policy.

Projecting future carbon emissions from cement production in developing countries

open access: yesNature Communications, 2023
Achieving low-carbon development of the cement industry in the developing countries is fundamental to global emissions abatement, considering the local construction industry’s rapid growth.

Are Carbon Emissions Associated with Stock Returns?

open access: yesSocial Science Research Network, 2023
An influential emerging literature documents strong correlations between carbon emissions and stock returns. We reexamine that data and conclude that these associations are driven by two factors.

Cities, traffic, and CO2: A multidecadal assessment of trends, drivers, and scaling relationships [PDF]

open access: yes, 2015
Emissions of CO2 from road vehicles were 1.57 billion metric tons in 2012, accounting for 28% of US fossil fuel CO2 emissions, but the spatial distributions of these emissions are highly uncertain.

A measurement-based upstream oil and gas methane inventory for Alberta, Canada reveals higher emissions and different sources than official estimates

open access: yesCommunications Earth & Environment, 2023
Mitigation actions and regulations to meet critical 2030 methane reduction targets under the Global Methane Pledge are hampered by uncertainty in true levels of emissions and source breakdowns. Here we present a measurement-based, source-resolved, hybrid

River plastic emissions to the world's oceans

open access: yesNature Communications, 2017
Plastics in the marine environment have become a major concern because of their persistence at sea, and adverse consequences to marine life and potentially human health.
