Disclosure of total GHG emissions

● Honda GHG emissions in FY2014

As a responsible company operating in the mobility industry, Honda believes in the importance of calculating and disclosing greenhouse gas (GHG) emissions in order to drive progress in initiatives to reduce global emissions.
As the first milestone in this endeavor, in August 2012 Honda became the world's first mobility company to disclose estimates of all GHG emissions from its entire value chain in conformity with the Greenhouse Gas Protocol (GHG Protocol),1 currently the world's most widely used GHG emissions accounting standard. We released estimates of FY 2012 emissions not only from our own business activities (scope 1 and 2), but also from all upstream and downstream activities (scope 3), extending from the procurement of raw materials to the transportation and customer use of Honda products, and ending with the treatment of end-of-life products.2
Honda continues to calculate and report its emissions, and is making improvements to get a more accurate assessment of emissions from our entire value chain. We are doing this in scope 3 (other indirect emissions), for example, by widening the boundaries of data collection3 for categories that account for the largest proportion of estimated emissions, and improving the accuracy of calculation methods. The calculations for FY 2014 show that GHG emissions from Honda business activities were 5.21 million t-CO2e, and total emissions from the value chain, including other indirect emissions, were 281.16 million t-CO2e. We hope to leverage these improvements in data measurement and management to devise more effective emissions reduction strategies.

3. The scope of data collection was broadened in fiscal 2013, capturing additional greenhouse gas emission amounting to 7% of total emissions. We will consider ways to further broaden this scope in fiscal 2014 and beyond.

Honda's total greenhouse gas emissions

●Scope 1: Direct GHG emissions from business activities, as defined by the GHG Protocol (examples: combustion of fuel oil at a manufacturing plant, emissions from work vehicles
and company cars). The scope 1 figures presented in this report include all GHGs emitted directly by Honda Motor Co. and its consolidated subsidiaries and affiliated companies worldwide.
●Scope 2: Indirect GHG emissions from a company's use of energy, as defined by the GHG Protocol (examples: electrical energy used by a manufacturing plant or office). The scope 2 figures presented in this report include all GHGs emitted directly by Honda Motor Co. and its consolidated subsidiaries and affiliated companies worldwide.
●Scope 3: Other indirect GHG emissions not included in scope 1 and scope 2, as defined by the GHG Protocol. Scope 3 is systematically broken down into 15 categories (examples: category 11 includes emissions arising from the use of sold products; category 12 includes emissions arising from the end-of-life treatment of sold products).
●The category 11 figures presented in this report represent the cumulative amount of greenhouse gases that will have been emitted by products sold by Honda in each fiscal year (automobiles, motorcycles, power products) as a result of their use by customers from the time they received those products until they dispose of them in the future. The "scope 3, other categories" figures presented in this report are the sum of emissions from categories 1, 2, 3, 4, 5, 6, 7, 9, 10, 12, and 15. As per the GHG Protocol, Honda excludes categories 8, 13, and 14 from its calculations, as these categories are either not part of Honda business activities or emissions from these categories are accounted for in other categories.
