During the recent virtual Leaders Summit on Climate,
President Biden announced his goal to cut greenhouse gas (GHG) emissions by
50-52% from 2005’s levels by the year 2030. This more than doubles the previous
US goals set in 2015 to cut emissions by 26-28% by the year 2025. Additionally,
President Biden also set a target to have net zero emissions economy-wide no
later than the year 2050. The focus on environmental standards would allow for
new infrastructure and thus new technologies and job creation.
Biden also re-entered the Paris Agreement, an international
treaty with the goal to tackle climate change. Some of the main objectives
include limiting greenhouse gas emissions caused by human activity to levels
that the earth can naturally absorb as well as setting national determined
contributions (NDCs) that are reviewed every five years to maintain and
increase climate change momentum.
The EPA is proposing a federal plan that would cut pollution from power plants and industrial sources that significantly contribute to unhealthy levels of ground-level ozone, or smog, for millions of Americans who live downwind.
The U.S. EPA signed an amendment to the rule on February 28, 2022 that removes the stay of the formaldehyde limit for lean premix and diffusion flame gas-fired units that were constructed or reconstructed after January 14, 2003.
“What’s in my CPM?” Many compounds can condense and form particulate matter at ambient conditions. Identifying which compound is most prevalent can help in determining control measures to reduce CPM.
