What is a GHG level?

What is a GHG level?

A greenhouse gas (GHG or GhG) is a gas that absorbs and emits radiant energy within the thermal infrared range, causing the greenhouse effect. Without greenhouse gases, the average temperature of Earth’s surface would be about −18 °C (0 °F), rather than the present average of 15 °C (59 °F).

What is scope 1 GHG Protocol?

The GHG Protocol Corporate Standard classifies a company’s GHG emissions into three ‘scopes’. Scope 1 emissions are direct emissions from owned or controlled sources. Scope 2 emissions are indirect emissions from the generation of purchased energy.

What are the 15 Scope 3 categories?

Emission Source Categories Using Scope 1 and 2 Emission Factors

  • Upstream leased assets (Category 8)
  • Processing of sold products (Category 10)
  • Use of sold products (Category 11)
  • Downstream leased assets (Category 13)
  • Franchises (Category 14)
  • Investments (Category 15)

Is GHG Protocol mandatory?

The proposal would cover 85 to 90 percent of US greenhouse gas emissions. This process is the result of legislation passed in December, 2007 that directed the EPA to design a national, mandatory GHG emissions registry.

Is embodied carbon Scope 3?

By measuring and reporting embodied carbon, built environment clients can take demonstrable action on Scope 3 emissions.

What are GHG scopes?

Scope 1 emissions are direct greenhouse (GHG) emissions that occur from sources that are controlled or owned by an organization (e.g., emissions associated with fuel combustion in boilers, furnaces, vehicles).

How are GHG emissions calculated?

Calculate your GHG emissions in tons, by type of GHG. GHG emission = 0.001 * Fuel Usage * High heat value *Emission factor. You can get these values from the EPA’s GHG Reporting Program (GHGRP) documentation and your own records.

Is Scope 3 reporting mandatory?

Different from scope 1 and 2 which are mandatory, scope 3 is an optional reporting category that, as said, allows for the accounting of all other indirect emissions. These are a consequence of the business’ supply chain activities, and so occur from sources not directly owned or controlled by the company.

Do you have to report on Scope 3 emissions?

The rules about Scope 3 are part of the UK government’s Streamlined Energy and Carbon Reporting (SECR) policy. At the time of writing (August 2020), only one type of Scope 3 emissions is compulsory to report, and it’s only compulsory for large unquoted companies and large LLPs.
