How do you make a carbon inventory?
GHG Inventory Development Resources
- Step 1: Get Started: Scope and Plan Inventory.
- Step 2: Collect Data and Quantify GHG Emissions.
- Step 3: Develop a GHG Inventory Management Plan.
- Step 4: Set a GHG Emission Reduction Target and Track and Report Progress.
What are the 4 main carbon footprint categories?
The major contributors to carbon footprints are: food, consumption, transportation, and household energy. Food is a major contributor to carbon footprints, and meat in particular is an issue. Livestock is responsible for a significant amount of greenhouse gas emissions, and beef is one of the biggest contributors.
What is methodology of greenhouse effect?
The methodology allows users to estimate (1) GHG impacts at project scale, (2) GHG emissions by agricultural practice, and (3) GHG emissions per unit of output (i.e., GHG emission intensity).
What is Emission Factor IPCC?
The Emission Factor Database (EFDB) is a project supported by the National Greenhouse Gas Inventories Programme (NGGIP), which is managed by the IPCC Task Force on National Greenhouse Gas Inventories (TFI).
Who uses GHG Protocol?
The GHG Protocol Corporate Accounting and Reporting Standard provides requirements and guidance for companies and other organizations, such as NGOs, government agencies, and universities, that are preparing a corporate-level GHG emissions inventory.
What is scope 1 GHG Protocol?
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).
What are 8 carbon footprints?
We analyze the contribution of 8 categories: construction, shelter, food, clothing, mobility, manufactured products, services, and trade.
What are Scope 3 carbon emissions?
Scope 3 emissions are the result of activities from assets not owned or controlled by the reporting organization, but that the organization indirectly impacts in its value chain. Scope 3 emissions include all sources not within an organization’s scope 1 and 2 boundary.
How do you calculate CO2 eq?
You calculate the carbon dioxide equivalent of a quantity of F gas by multiplying the mass of the gas (in tonnes), by the gas’ global warming potential (GWP)….Example calculation
- Mass (in tonnes) of F gas multiplied by GWP of F gas.
- = (10/1,000) * 3,922.
- = 39.2 tonnes CO2 equivalent.
What are scope 1/2 and 3 carbon emissions?
Definitions of scope 1, 2 and 3 emissions Essentially, scope 1 and 2 are those emissions that are owned or controlled by a company, whereas scope 3 emissions are a consequence of the activities of the company but occur from sources not owned or controlled by it.
How do you measure carbon emissions?
By measuring its presence or absence in a particular parcel of air, researchers can track down how much CO2 in that air came from natural biogenic sources and how much from burning fossil fuels. And if the parcels are carefully chosen, that analysis can pinpoint the sources of emissions.
What are the 15 categories of Scope 3?
Guidance by Scope 3 Category
- Category 6 – Business travel.
- Category 7 – Employee commuting.
- Category 8 – Upstream leased assets.
- Category 9 – Downstream transportation and distribution.
- Category 10 – Processing of sold products.
- Category 11 – Use of sold products.
- Category 12 – End-of-life treatment of sold products.
What does Net Zero refer to?
Put simply, net zero means cutting greenhouse gas emissions to as close to zero as possible, with any remaining emissions re-absorbed from the atmosphere, by oceans and forests for instance.
What is the best resource to learn about carbon inventory methods?
Carbon Inventory Methods Handbook provides detailed step-by-step information on sampling procedures, field and laboratory measurements, application of remote sensing and GIS techniques, modeling, and calculation procedures along with sources of data for carbon inventory.
Can forest inventory data be used for National Carbon inventory?
Data from such forest inventories could be used for the national carbon inventory. Guidance on preparing a forest inventory, particularly for above-ground biomass and commercial or merchantable timber is available in literature (Kangas and Maltamo 2006).
What is not included in a forest inventory?
• Normally, forest inventory provides estimates of above-ground biomass, particularly commercial or merchantable timber, and it may not include estimates for soil organic carbon, below-ground biomass, deadwood and litter pools
How to increase the accuracy of inventory estimates?
Combining the tiers Although it is desirable to adopt higher tiers for all key land-use categories, subcategories and carbon pools, it may not be feasible due to data and resource limitations. The next best approach is to adopt a combination of tiers for increasing the accuracy of the inventory estimates.
