Board Networks and Corporate Carbon Emissions: A Cross‐Country Analysis of Causal Effects

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines whether board networks influence corporate carbon emissions and the strategic pathways through which firms decarbonize. Using a sample of 1952 firms across 48 countries from 2003 to 2020, we employ dynamic stacked regressions that exploit exogenous carbon‐regulation shocks affecting firms connected through shared third ...

Three-dimensional shock-sulfur hexafluoride bubble interaction

AIP Advances, 2019
The evolution of shock-sulfur hexafluoride (SF6) bubble interaction is investigated using a detailed three-dimensional numerical simulation. The influences of the end wall distance on the bubble evolution are analyzed by using the high-resolution ...

Validation of a new spectrometer for noninvasive measurement of cardiac output [PDF]

, 2004
Acetylene is a blood-soluble gas and for many years its uptake rate during rebreathing tests has been used to calculate the flow rate of blood through the lungs (normally equal to cardiac output) as well as the volume of lung tissue.

Exploring the Interrelationships Among Supply Chain Emissions, Financial Performance, Market Value, and Board Sustainability: An Exploration of the European Landscape

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT National and supranational institutions are establishing emission trading systems and control schemes in an attempt to manage stakeholders' willingness to engage with regulatory systems and reduce greenhouse gas emissions (GHG). Nonetheless, despite the national and supranational focus on carbon neutrality, little research has been centered ...

Estimating changes in ocean ventilation from early 1990s CFC-12 and late 2000s SF6 measurements [PDF]

, 2013
Transient tracer measurements can constrain the rates and pathways of ocean ventilation and act as proxies for biogeochemically relevant gases such as CO2 and oxygen.

Carbon emission assessment of tunnel infrastructures: From construction to operation

Deep Underground Science and Engineering, EarlyView.
This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...

Rumen methanogenic archaea and their correlation with enteric methane emission in ruminant animals: A systematic review and meta‐analysis

JSFA reports, EarlyView.
Abstract Background Livestock, especially ruminants, are a major source of global methane emissions, primarily produced by methanogenic archaea during enteric fermentation. We performed a systematic review and meta‐analysis to account for factors that could influence the relationship between ruminal methanogenic populations and methane emissions, such ...

Age of air from ACE-FTS measurements of sulfur hexafluoride [PDF]

Atmospheric Chemistry and Physics
Climate models predict that the Brewer–Dobson circulation (BDC) will accelerate due to tropospheric warming, leading to a redistribution of trace gases and, consequently, to a change of the radiative properties of the atmosphere.

Sulfur hexafluoride (SF₆) emissions in East Asia determined by inverse modeling [PDF]

Atmospheric Chemistry and Physics, 2014
Sulfur hexafluoride (SF6) has a global warming potential of around 22 800 over a 100-year time horizon and is one of the greenhouse gases regulated under the Kyoto Protocol. Around the year 2000 there was a reversal in the global SF6 emission trend, from
