Carbon Offsetting

What is Carbon Offsetting

To generate HCM’s carbon offsets, we observe and decrease CO2 emitted via our operations, then purchase carbon credits generated by the CO2 decreased through domestic green energy initiatives (planting/forest preservation etc), thereby offsetting our own emissions, and allowing HCM to both support green initiatives and lower CO2.

At HCM, we uphold our mottos such as “We contribute to the prevention of global warming”, “We assist highly environmentally-aware stakeholders (i.e. customers, etc.)” and “We strive to reduce CO2 emissions associated with our business activities as much as possible.” Driven by these, we have been endeavoring to prevent global warming throughout the entire life- cycle of our products, as well as establishing and implementing a support/promotion cycle model for CO2 emission reduction projects through carbon offsetting and introducing the J-Credit scheme (formerly the “domestic CDM”). This type of model that combines the introduction and ongoing use (the redeeming) of a carbon credit scheme is an industry-first initiative.

HCM CO2 Reduction Activity

At HCM Group, we strive to prevent global warming throughout the life-cycle of our products.

Carbon Offset Initiatives

At HCM Group, we are implementing carbon offsetting in the following two areas:

1. Product-type carbon offsetting to support the customer’s environmental activities
2. Community contribution-type carbon offsetting for the purpose of supporting communities

Out of the overall CO2 emissions occurring throughout the construction machinery’s life cycle, approx. 90 percent is emitted during product operation, with CO2 emissions during manufacturing being below 1 percent.
In order to support the global warming prevention activities of our stakeholders and customers, HCM is upholding a carbon offset policy focusing not only on offering energy-saving products and products that do not use fossil fuel to fulfill our responsibility as a manufacturer, but also on providing products with zero CO2 emissions during the manufacturing stage (carbon-offset products).

HCM Product Type Carbon Offset Policy

1. Promote the spread of products that contribute to environmental preservation (e.g. forestry work) over conventional machines.

2. Actively support a national global warming prevention movement.

Products Type Carbon Offset

At HCM, we calculate the amount of CO2 emitted during product assembly, and carry out offsetting for 0.5 t of CO2 per mini-excavator, 1 t per 7-16 t hydraulic excavator, and 2 t per heavier hydraulic excavator.

Carbon Credit

In 2008 when these activities were first started, we had adopted the CER in the Clean Development Mechanism (CDM) defined by the United Nations. However, in recent years we have been making a shift to the J-Credit scheme to support domestic CO2 reduction projects with our products. From 2010, we utilized J-VER credits obtained through the introduction of wood biomass boilers fueled by tree bark produced during forest thinning’s in place of bunker A-fueled boilers by a customer in Shikoku who carried out forestry work with construction machinery. At the same time, we registered our first methodology involving construction machinery with METI’s J-Credit scheme, and have been actively supporting our “emission reduction projects” where our customers generate credits based on this methodology.

HCM Carbon Offset Forest

We have defined “HCM’s Carbon Offset Forest” to visualize the outcome of our carbon offset activities in terms of the number of cedar trees, as a self-intelligible means to further promote these activities and facilitate a greater consensus.
At HCM, we have been carrying out carbon offset activities since November 2008. By March 2018, the cumulative total amount of carbon offset exceeded 1,474 tons, which is equivalent to the CO2 amount absorbed by approx. 105,286 cedar trees.
