GHG Emissions
GHG Emissions GHG emissions are gases released into the atmosphere that trap heat, contributing to global warming and climate change. The main types include carbon dioxide (CO₂), methane (CH₄), nitrous oxide (N₂O), and fluorinated gases. To help organizations understand and manage their emissions, they’re classified into three “scopes” based on their source and control level.

Fine Particulate Matter
Fine Particulate Matter Fine particulate matter are microscopic particles suspended in the air, known as aerosols. PM10 includes particles smaller than 10 micrometers, and PM2.5 refers to those under 2.5 micrometers. These particles originate from human activities (e.g., industry, transport, agriculture) and natural sources (e.g., wildfires, volcanic eruptions) or form through chemical reactions in the…

Net zero emissions
Net zero emissions Net zero emissions refers to the balance between the amount of greenhouse gases emitted and the amount removed from the atmosphere, resulting in no net increase in atmospheric GHG. Achieving net zero involves reducing emissions as much as possible through measures such as transitioning to renewable energy, improving energy efficiency, and adopting…

Greenhouse gas
Greenhouse gas Greenhouse gases (GHG) are those gaseous constituents of the atmosphere, both natural and anthropogenic, that absorb and emit radiation at specific wavelengths within the spectrum of terrestrial radiation emitted by the Earth’s surface, the atmosphere itself and by clouds. Water vapor (H2O), carbon dioxide (CO2), nitrous oxide (N2O), methane (CH4) and ozone (O3)…
