The US, Canada, and Mexico have submitted a proposal to strengthen climate protection under the Montreal Protocol— the international treaty that phases out the production of a number of substances responsible for ozone depletion. The proposal targets the production and use of HFCs, a group of “super” greenhouse gases. Source: IGSD.

Between 2009 and 2011, up to 96% of city dwellers were exposed to fine particulate matter (PM 2.5 ) concentrations above WHO guidelines and up to 98% were exposed to ozone (O 3 ) levels above WHO guidelines. These EU limits or targets are in certain cases less strict than WHO guidelines.

NO 2 is just one component of air pollution, which is made up of many pollutants (including particulate matter, ozone, carbon monoxide), which are known to have numerous adverse effects on health. The researchers estimate that most children lived in areas below the current WHO guideline of 21 parts per billion for annual average NO 2.

EPA also is issuing draft Control Techniques Guidelines (CTGs) for reducing VOC emissions from existing equipment and processes in the oil and natural gas industry. Those benefits include reductions in health effects related to fine particle pollution, ozone and air toxics, along with improvements in visibility.

In this sense, the “business-as-usual” projections equal the “with measures” scenario called for under the UNFCCC Guidelines for Annex 1 Communications. The submission of the document, also called the US Climate Action Report 2010, is a requirement under the UN Framework Convention on Climate Change.

MARPOL Annex VI sets limits on NO x and SO x emissions from ship exhaust, and prohibits deliberate emissions of ozone-depleting substances. Both options would provide guidelines for limiting vessel operations within the areas and specifying either speed limits or fuel requirements for operation, both of which could reduce emissions.

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. Recommended 2021 AQG levels compared to 2005 air quality guidelines. When action is taken on these classical pollutants—particulate matter (PM), ozone (O?), Source: WHO.
