Study finds global emissions of several banned ozone-destroying CFCs are increasing

Green Car Congress

But because they’re potent greenhouse gases, they still affect the climate. That’s equivalent to about one percent of the total greenhouse gas emissions in the United States. Although the team found rising global emissions, they weren’t able to identify particular locations. —Dr Western Resources Western, L.M.,

IEA: global CO2 emissions rebounded to their highest level in history in 2021; largely driven by China

Green Car Congress

Global energy-related carbon dioxide emissions rose by 6% in 2021 to 36.3 The rebound of global CO 2 emissions above pre-pandemic levels has largely been driven by China, where they increased by 750 million tonnes between 2019 and 2021. billion tonnes, accounting for 33% of the global total. billion tonnes. billion tonnes.

Global Carbon Project: Global carbon emissions growth slows, but hits record high

Green Car Congress

Driven by rising natural gas and oil consumption, levels of CO 2 are expected to hit 37 billion metric tons this year, according to new estimates from the Global Carbon Project (GCP), an initiative led by Stanford University scientist Rob Jackson. and China account for more than half of all carbon dioxide emissions globally.

UGA study finds black carbon aerosols from GDI engines will worsen public health, climate; need for GPFs

Green Car Congress

A strong absorber of solar radiation, black carbon exhibits significant climate warming properties. On the other hand, the reduction in CO 2 emissions associated with the enhanced fuel economy of GDI vehicles would yield a globally uniform negative radiative effect, estimated to be ?0.013 W/m 2 over urban regions. —Rawad Saleh.

NREL researchers use adversarial training to super-resolve climate data; up to 50X higher resolution data

Green Car Congress

Researchers at the US Department of Energy’s (DOE’s) National Renewable Energy Laboratory (NREL) have developed a novel machine learning approach quickly to enhance the resolution of wind velocity data by 50 times and solar irradiance data by 25 times—an enhancement that had yet to be achieved with climate data. —Stengel et al.

United States and China agree to work together on phasing down HFCs

Green Car Congress

The United States and China will work together and with other countries to use the expertise and institutions of the Montreal Protocol to phase down the consumption and production of hydrofluorocarbons (HFCs), among other forms of multilateral cooperation.

ICCT LCA study finds only battery and hydrogen fuel-cell EVs have potential to be very low-GHG passenger vehicle pathways

Green Car Congress

The ICCT has conducted a comprehensive global and temporal life-cycle assessment of GHG emissions from a variety of alternative passenger car powertrains and fuels. This study incorporates the near-term global warming potential of methane leakage emissions of natural gas and natural gas-derived hydrogen pathways.
