The US Environmental Protection Agency (EPA) issued final New Source Performance Standards (NSPS) to reduce emissions of methane-rich landfill gas from new, modified and reconstructed municipal solid waste (MSW) landfills, updating standards that were issued in 1996. In 2014, methane emissions from MSW landfills represented 18.2%
The US Environmental Protection Agency (EPA) released its latest set of proposed standards to reduce emissions of methane and volatile organic compounds (VOCs) from the oil and natural gas industry. The proposed updates also add emissions reduction requirements for sources of methane and VOC pollution that were not covered in the 2012 rules.
At a time when pollution regulations are increasingly focused on the emissions ships generate, the SCiB will contribute to the protection of the marine and global environments. The certification is based on Class NK’s “Guidelines for Large-capacity Storage Batteries,” which requires use of a BMU in the system as a safety feature.

The researchers reported these results in the journal Diabetes.
London’s £10 daily “ T-Charge ” (toxicity), aimed at the oldest, most polluting vehicles on London roads, is now in effect. The T-Charge (officially known as the Emissions Surcharge) operates on top of (and during the same operating times as) the Congestion Charge (Monday to Friday 7am-6pm), so it will cost £21.50
UK Environment Secretary Michael Gove published a new Clean Air Strategy to cut air pollution backed up through new primary legislation.

These proposals are in addition to the government’s £3.5-billion billion (US$4.7-billion)
According to UAI, the EPA has published inaccurate data for years claiming that ethanol increases emissions, even though ethanol’s pollution reducing qualities have been demonstrated repeatedly. In the real world, blending ethanol into ordinary gasoline reduces harmful emissions produced when gasoline combusts in an engine.
The UK’s Low Carbon Vehicle Partnership has launched a Good Practice Guide for Local Measures to Encourage the Uptake of Low Emission Vehicles. The Good Practice Guide for Local Measures to Encourage the Uptake of Low Emission Vehicles was prepared for the LowCVP by Urban Foresight.
Many communities near major refineries live in fear of exposure to airborne pollutants during a major refinery incident—or during normal operations. The CARB-CAPCOA report is part of a broader initiative set in place in 2013 to address refinery safety and emissions in response to a major fire in 2012 at the Chevron Refinery in Richmond.

This will make Mercedes-Benz the only manufacturer to offer a locally emission-free model in all van segments. Furthermore, every stage of the battery cell providers' supply chains will be inspected according to OECD guidelines. Along with CO 2 emissions, road traffic also produces significant levels of particle pollution.
And, thanks to a little-known Environmental Protection Agency stipulation and government incentives, businesses have every reason to reduce employees’ commute emissions as well. Scope 2 emissions are indirect greenhouse gas emissions associated with the purchase of electricity, steam, heat, or cooling.
Unbeknownst to many, manufacturing new automobiles exacts a toll on our ecosystem—increased energy consumption and escalating greenhouse gas emissions further exacerbate the situation. The Art of Dismantling and Depollution: Next, we delve into dismantling and de-pollution, where hazardous materials are carefully purged.
New WHO has issued new Global Air Quality Guidelines (AQGs) that reduce levels of key air pollutants, some of which also contribute to climate change. Since WHO’s last 2005 global update, there has been a marked increase of evidence that shows how air pollution affects different aspects of health. Source: WHO.
EPR guidelines and recycling targets The EPR guidelines, which came into effect in July 2022, set a recycling target of 70% of the weight of new tyres manufactured or imported in FY 2022 for FY24. However, in the process of tyre consumption, when the emissions are created, who is responsible?
