Honda discloses estimates of annual greenhouse gas emissions related to its operations and customer use of products

Honda Motor Co., Ltd. disclosed estimates of all greenhouse gas (GHG) emissions related to Honda including emissions from Honda’s global business operations and customer use of Honda motorcycles, automobiles and power products. Honda is the first mobility company to do so, according to its internal research.

The estimates of GHG emissions were calculated in conformity with the Greenhouse Gas Protocol—a guideline determined by the World Business Council for Sustainable Development and the World Resources Institute for GHG accounting. The GHG Protocol defines three scopes of emissions by categorizing different business activities. Honda has been disclosing all Scope 1 and Scope 2 emissions since 2009 and disclosed a part of Scope 3 emissions (global Category 11 emissions) for the first time on June 20, 2012. With the new disclosure of all Scope 3 emissions—which includes customer use—Honda has disclosed all GHG emissions defined by the GHG Protocol.

Honda also disclosed for the first time on its website conditions for the calculation of data required to determine Scope 3 Category 11 emissions, including customers’ lifetime product use and annual traveling distance.

Honda’s GHG emissions during the fiscal year ended 31 March 2012
Scope Description Emissions
Scope 1 Direct emissions from operations that are owned or controlled by the reporting company. (E.g. emissions from combustion of fuel oil at factories, emissions from corporate vehicles, etc.) 1.24 million
Scope 2 Indirect emissions from the generation of purchased or acquired electricity, steam, heating, or cooling consumed by the reporting company (E.g. electricity use at factories and offices, etc.) 2.96 million
Scope 3
Category 11
Emissions from customer use of purchased products. 195.88 million
Scope 3 All other categories 24.98 million
Overall GHG emissions from Honda and Honda products 225.06 million

This illustration can also help to dispel the myth that buying a new, more fuel efficient vehicle is bad for the environment, since it cost energy more to produce it than can ever be recovered...

87% of energy use stem from operating the vehicle, so energy savings in the operational phase quickly add up to a positive balance.


Honda and other car compagnies are only subsidaries compagnies owned and operated indirectly by big oil capital investors. They are there to make sell polluting costly petrol. All their research and devellopments about an increase in mpg are just fuss and hoax and they never discovered anything better since 100 years. When they discover something better, they just make patents about it and never commercialize it and they are ready to sues or currupt anyone trying to begin commercialisation of an alternative technology. The rest of the money is invested in promotion of guilty political interest in that petrol-car monopoly. This website is just one of their false pr campaign outlet.


AD is always good for comic relief; he might be talking about Government Motors (which at one point had a market cap below XOM's quarterly profit), but not Honda.

You have to wonder how this appraisal would change if nuclear energy was exploited to maximum advantage.  Any process step involving steam would become carbon-free, metal smelting would probably use electric furnaces, and the vehicles themselves would be battery-powered for most of their operation and slash the user emissions by at least 2/3.
