Prevention of Global Warming from Products

Initiatives for Prevention of Global Warming

In order to reduce CO2 emissions throughout the lifecycle of products, Pioneer conducts a Life Cycle Assessment (LCA), analyses CO2 emissions and visualizes reduced amounts in emissions in comparison with conventional products and initiates global warming prevention activities.

Reduction of Power Consumption by Digital Technology

With amplifiers, which are the core components of audio systems, we realized a halving of power consumption by our original digital technology. This digital amplifier technology is incorporated into high-end products to mainstream products for household use as well as in audio products for automobiles.

CO2 Reductions in Transportation by Energy Savings in Distribution

We are engaged in reducing fuel consumption as a way of saving energy in the transportation of raw materials and products. We are also engaged in reducing fuel consumption as a way of saving energy in the transportation of our products. We started by streamlining our physical distribution bases and simplifying the distribution steps, and have also introduced a milk-run* system for shortening transportation distances from several parts makers. In regard to transportation means, we are carrying out a modal shift of switching from truck transportation to railway and maritime transportation. Also, we address reductions in product size and weight (downsizing) and promote transportation efficiency and reductions in fuel consumption.  

  • * A system in which a single transportation service makes a round among several suppliers to perform efficient pickup of production parts from suppliers.

Searching for Routes Enabling Good Fuel Consumption with Car Navigation Products

Our car navigation may realize an energy-saving drive by searching for a route with lesser gasoline consumption.

Example of reductions in gasoline consumption by evolutionary advancements in route searches

Realization of Eco-Drive with Reductions in Power Consumption

Different from gasoline vehicles, an EV stores electric power by using regenerative braking when decelerating allowing longer use of batteries on routes having appropriate decelerating zones. The EV dedicated navigation searches more ecological routes before departure with "EV-dedicated Eco-Route Search", eliminating worries about battery depletion and realizes efficient drive.

Example of CO2 reduction by using the EV dedicated navigation

Reduces Power Not in Use

Also, most electronic products consume power, even slightly, just with the plug being inserted in the outlet. We even turned our attention to this power and were able to reduce standby power consumption to no more than 0.5 W.

Products for Vehicles

AV Main Unit MVH-790

These products are for enjoying enhanced music experience in vehicles. AV main units are small products which are fitted into dash board of vehicle, and the CO2 emissions are not large. However, MVH-790 aimed for further reductions, decreased the main body volume by 41% and the main body mass by 28%*. By achieving downsizing, CO2 emissions in "raw materials" and "transportation" have been significantly reduced. In addition, MVH-790 reduces power consumption in use, also minimizes backup current not in use to reduce vehicle battery loads and reduce CO2 emissions in "use".

* Details are introduced in the section "Eco-Friendliness in Cars".

MVH-790

LCA calculation conditions
Fuel consumption: Weighted average for actual fuel consumption of top ten best selling cars in 2008, according to the Japan Automobile Dealers Association
Driving condition: 800 km per month
This model is operating while driving and duration of usage are six years.

  • * Represent emissions throughout the lifecycle. CO2e is a carbon dioxide conversion value of greenhouse gas. The same applies below

Raku-Navi AVIC-MRZ099

This product also allows you to enjoy music and video content as well as car navigation.
Raku-Navi is a compact product which is fitted into the dashboard of vehicles, however, the AV function as well as car navigation function have been enhanced. Therefore, the "raw material" ratio in CO2 emissions is large. For this reason, we have pursued a reduction in the number of parts and CO2 reduction activities among suppliers. The ratio of "use" is large, but this is a calculation in a state that the following fuel consumption improvement function is not used.
In fact, use of the following functions results in improvement in fuel consumption. Raku-Navi proposes a route with the lowest gasoline consumption by the "Smart Loop Congestion Information" and "Eco-Route Search" with our "Fuel Consumption Estimation Technology" and contributes to reductions in CO2 emissions. Moreover, the Eco-Status function assists driving with low fuel consumption.
