Heavy-duty vehicle emission characteristics based on the remote-monitoring three-bin moving-average window method [PDF]

E3S Web of Conferences, 2023
A three-bin moving average window (3B-MAW) model was proposed and compared with the work-based window method (WB-WM) to investigate the on-road emission characteristics of heavy-duty vehicles. The invalid data of remote monitoring were mainly composed of

The Role of BECCS in Achieving Climate Neutrality in the European Union

Energies, 2021
The achievement of climate neutrality in the European Union by 2050 will not be possible solely through a reduction in fossil fuels and the development of energy generation from renewable sources.

Howland Forest, ME, USA: Multi-Gas Flux (CO₂, CH₄, N₂O) Social Cost Product Underscores Limited Carbon Proxies

Land, 2021
Forest carbon sequestration is a widely accepted natural climate solution. However, methods to determine net carbon offsets are based on commercial carbon proxies or CO2 eddy covariance research with limited methodological comparisons. Non-CO2 greenhouse

Global observational coverage of onshore oil and gas methane sources with TROPOMI

Scientific Reports, 2023
Satellite observations have been used to measure methane (CH4) emissions from the oil and gas (O&G) industry, particularly by revealing previously undocumented, very large emission events and basin-level emission estimates.

Can We Vacuum Our Air Pollution Problem Using Smog Towers?

Atmosphere, 2020
In November 2019, the Supreme Court of India issued a notification to all the states in the National Capital Region of Delhi to install smog towers for clean air and allocated INR 36 crores (~USD 5.2 million) for a pilot.

Reduction of Signal Drift in a Wavelength Modulation Spectroscopy-Based Methane Flux Sensor

Sensors, 2022
Accurately quantifying unsteady methane venting from key oil and gas sector sources such as storage tanks and well casing vents is a critical challenge. Recently, we presented an optical sensor to meet this need that combines volume fraction and Doppler ...

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

Communications 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
