The study, set in Singapore, suggests that better air quality will bring about climate co-benefits in reducing electricity generation via lower household demand, and thus mitigating carbon emissions. This is important for policymakers when forecasting and influencing future emissions paths in the context of climate change.
In early 2013, the Chinese government declared a war on air pollution and began instituting stringent policies to regulate the emissions of PM 2.5. Cities restricted the number of cars on the road, coal-fired power plants reduced emissions or were shuttered and replaced with natural gas. Over the course of five years, PM 2.5
Jacobson, professor of civil and environmental engineering at Stanford University, suggests that carbon capture technologies are inefficient and increase air pollution. However, this research finds that it reduces only a small fraction of carbon emissions, and it usually increases air pollution.
HFCs are considered to be super pollutants because they trap heat in the atmosphere thousands of times more effectively than carbon dioxide, the most prevalent greenhouse gas. California is required to reduce HFC emissions 40% below 2013 levels by 2030 under Senate Bill 1383. This equipment often leaks refrigerants over time.

Battery electric cars emit less greenhouse gases and air pollutants over their entire life cycle than petrol and diesel cars, according to a European Environment Agency (EEA) report. Emissions are usually higher in the production phase of electric cars, but these are more than offset by lower emissions in the use phase over time.
The US Environmental Protection Agency (EPA) and US Department of Energy (DOE) are partnering to provide more than $1 billion in funding to help reduce methane emissions from the oil and gas sector through the creation of the Methane Emissions Reduction Program. Includes flexibilities and exemptions.
Levels of two major air pollutants have been reduced significantly since lockdowns began in response to the COVID-19 pandemic, but a secondary pollutant—ground-level ozone—has increased in China, according to new research. Maybe this unintended experiment could be used to understand better the emission regulations.
The US Department of Transportation’s Federal Highway Administration (FHWA) announced a Notice of Proposed Rulemaking ( NPRM ) for states and municipalities to track and reduce greenhouse gas (GHG) emissions. BIL also includes $7.2 The proposed rule is expected to publish in the Federal Register next week.
On this basis, and of Pareto efficiency, Emissions Analytics argues, until battery-electric vehicles can reach certain performance characteristics, government and industry support should switch immediately from EVs to full hybrids to create maximum welfare. Every air pollutant is more than 90% its limit.
Although large emissions cuts are urgently needed to achieve global climate goals, it may take decades before we can measure the effect of the reductions on global temperature evolution, according to a new study by researchers at Norway’s CICERO Center for International Climate Research. Fuglestvedt and Marianne T.
Diesel generators release greenhouse gases, particulate matter (PM), volatile organic compounds (VOCs), nitrous oxides (NO x ) and sulfur dioxide (SO 2 ), harmful pollutants that create smog and exacerbate respiratory conditions. Emissions from these backup generators can harm local residents, regional air quality and the global climate.
The California Air Resources Board on Friday approved the Innovative Clean Transit regulation (ICT) ( earlier post )—a first-of-its-kind regulation in the US that sets a statewide goal for public transit agencies to gradually transition to 100% zero-emission bus (ZEB) fleets by 2040.
