What is 'E' in ESG Rating?

March 26, 2023


Climate change is becoming increasingly apparent, and companies that fail to take steps to mitigate their impact on the environment may face reputational damage and financial losses. Investors are increasingly looking for companies that are committed to sustainability, and ESG rating is one of the key metrics used to evaluate a company's commitment to sustainability. Companies with high ESG ratings are often seen as more attractive investment opportunities, as they are likely to have lower risks associated with environmental issues. But what exactly is "E" in ESG rating?


The 'E' in ESG rating stands for 'Environmental' and refers to a company's utilization of resources and the effect of their operations on the environment.


When evaluating a company's environmental impact and sustainability efforts, ESG rating agencies typically consider a range of metrics. Some of the typical environmental metrics used in ESG rating include:

  1. Carbon emissions: This metric measures the greenhouse gas emissions released by a company during its operations, particularly carbon dioxide. It is an important indicator of a company's contribution to climate change.

  2. Energy consumption: This refers to the amount of energy a company uses in its operations, including electricity, fuel, and other sources. A lower energy consumption indicates a company's efforts to reduce its energy footprint and embrace energy-efficient practices.

  3. Water usage: This metric tracks the amount of water consumed by a company during its operations, reflecting its commitment to water conservation and efficient water management.

  4. Waste management: This measures how well a company manages its waste production, including recycling, reuse, and proper disposal of hazardous materials.

  5. Biodiversity and land use: This metric evaluates a company's impact on local ecosystems, including the preservation of habitats, the protection of endangered species, and responsible land use.


In addition to environmental metrics, ESG rating agencies also consider social and governance metrics when evaluating a company's sustainability efforts, to be able to provide a comprehensive assessment of a company's sustainability efforts. These ratings can be a valuable tool for investors looking to make informed and responsible investment decisions that align with their values and sustainability goals.
