  • 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.

  • 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)…

  • Greenhouse effect

    Greenhouse effect The greenhouse effect is a natural process that occurs when certain gases in the Earth’s atmosphere, known as greenhouse gases, trap heat from the sun. These gases allow sunlight to enter the atmosphere and reach the Earth’s surface. However, they also absorb and re-radiate infrared radiation emitted by the Earth, trapping heat in…

  • Climate Transition Benchmarks

    Climate Transition Benchmarks A climate benchmark is defined as an investment benchmark that incorporates specific objectives related to greenhouse gas (GHG) emission reductions and the transition to a low-carbon economy — based on the scientific evidence of the IPCC — through the selection and weighting of underlying constituents. These benchmarks are intended to serve as…

  • Climate Change

    Climate Change Climate change refers to the long-term variations observed in weather conditions due to the warming of the Earth’s atmosphere. These variations include changes in temperature, precipitation, wind patterns and other aspects of the climate system. Although natural processes, such as the solar cycle or massive volcanic eruptions, can contribute to these changes, human…

  • Carbon pricing

    Carbon pricing

    Carbon pricing Carbon pricing is an instrument that captures the external costs of greenhouse gas (GHG) emissions—the costs of emissions that the public pays for, such as damage to crops, health care costs from heat waves and droughts, and loss of property from flooding and sea level rise—and ties them to their sources through a…

  • Carbon Footprint

    Carbon Footprint As stated by Mike Berners-Lee, author of The Carbon Footprint of Everything, a carbon footprint is the “total sum of all the greenhouse gas emissions that had to take place in order for a product to be produced or for an activity to take place”. Each of these activities and products has its…

  • Carbon allowances, credits and offsets

    Carbon allowances, credits and offsets Carbon allowances and carbon credits/offsets form part of carbon markets that attempt to reduce greenhouse gas emissions by putting a price on them, effectively turning CO2 into a commodity. While the terms are often used interchangeably, they trade on two distinct markets: carbon allowances – an official, or compliance market;…
