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

Commercial forest carbon protocol over-credit bias delimited by zero-threshold carbon accounting

open access: yesTrees, Forests and People, 2022
The validity of forest carbon offsets is increasingly called into question. However, despite the use of commercial forest carbon protocols (CFCPs) for more than two decades, claiming ∼566 MMtCO2e and a market value of ∼USD $15.7 billion, comparative ...

California air resources board forest carbon protocol invalidates offsets [PDF]

open access: yesPeerJ, 2019
The commercial asset value of sequestered forest carbon is based on protocols employed globally; however, their scientific basis has not been validated. We review and analyze commercial forest carbon protocols, claimed to have reduced net greenhouse gas ...

Informal emissions

open access: yes, 2022
Environmental regulations and their enforcement play a critical role in reducing emissions and their devastating effects on humanity and the environment. However, many developing countries have large informal sectors—accounting for more than 70 percent of total employment, that operate outside

Towards Climate Neutrality in Poland by 2050: Assessment of Policy Implications in the Farm Sector

open access: yesEnergies, 2021
Climate neutrality achievement in the European Union assumes the necessity of efforts and transformations in most economic sectors of its member-states. The farm sector in Poland, being the second largest contributor to the country’s greenhouse gas (GHG)

Nocturnal emissions [PDF]

open access: yesEMBO reports, 2011
Howy argues that sophisticated communication technology is no substitute for the face‐to‐face contacts that are vital to scientific work. Instead of ever‐fancier electronic devices, we should be focusing on making travel more efficient and humane.

Experimental Investigation of Zn2+ Impact on Hydration, Carbonation, and Strength of CSA Cement [PDF]

open access: yesE3S Web of Conferences
This study explores the effects of Zn2+ incorporation on the hydration and carbonation behavior of calcium sulfoaluminate (CSA) cement. CSA clinker with varying Zn2+ contents was synthesized using ZnSO4·7H2O as the heavy metal source.
