INTRODUCTION. This briefing paper explains how policymakers can account for well-to-wake (WTW) carbon dioxide equivalent (CO2e) emissions in strategies that aim to monitor or regulate climate-warming pollutants from ships.
This briefing paper outlines a methodology for calculating well-to-wake carbon dioxide equivalent emissions from four fossil marine fuels: heavy fuel oil, very low sulfur fuel oil, marine gas oil, and liquefied natural gas. Well-to-wake emission factors for these fuels are presented in Table 13.

- Background: How Fera Is Calculated For Purchased Electricity
Fuel and energy-related activities are the upstream (Greenhouse Gas Protocol Scope 3, category 31) emissions arising as a result of fuel combustion either directly (Scope 1) or indirectly (Scopes 2 and 3). These are: 1. Mining / extracting / refining and producing the fuel (well-to-tank / WTT) 2. Transporting the fuel (or energy) to the point of us...
The emission factor database (EFDB(opens in a new tab)) contains FERA emission factors for several countries including UK, USA, France and Germany that may be used directly for reporting the upstream impact of purchased energy under the Scope 2 location-based approach. These factors may also be used to report under the market-based approach in cert...
Scope 3 upstream emissions are closely linked to Scope 2 (generation) emissions. However, whereas emissions from generation depend mainly on the fuel burned, the two elements of upstream emissions are affected by other variables; well-to-tank (WTT) emissions depend on how the fuel was produced, and transmission and distribution losses (T&D) depend ...
For BEV and PHEV cars: emissions from electricity generation, along with WTT for electricity generation, transmission and distribution losses and WTT for transmission and distribution, as well as WTT for fuels for PHEV cars are calculated by Climatiq’s Energy endpoint.
Emission intensity of Well-to-Tank (WTT) for passenger vehicles and business travel on land. EF should be used to report the upstream Scope 3 emissions associated with extraction/refining and transportation of the raw fuels before they are used to power the transport mode.

What are WTT emissions?
How do you calculate WTT emission factors for marine fuels?
What is the difference between fuel_N F UELN and EF_ WTT?
WTT emissions account for the emissions arising from the extraction, production, and transportation of fuels consumed or used to generate electricity. Since WRI does not produce energy directly, it uses the average-data method to estimate emissions by using secondary regional-average emission factors for upstream emissions per unit of consumption.
