Environmental Contribution of LED Headlamps |
Thousand t-CO₂ | 218.3 | 287.0 | 373.8 | 465.5 | 558.1 |
KOITO has calculated the contribution by referring to the calculation methodologies on the EUʼs "Technical Guidelines for the preparation of applications for the approval of innovative technologies pursuant to Regulation (EC) No 443/2009 and Regulation (EU) No 510/2011" and JAPIAʼs "Second Version of Regulation 2 of the Guidelines for Calculating LCI (Data Chart for Calculating Environmental Impact at the Stage of Use)."
[Calculation formula]
Energy-saving effect* (W/units) / 1,000 × Consumption of effective power (ℓ/kWh) / Efficiency of alternator × CO₂ emission factor (t-CO₂/ℓ) × Operating hours (hours/year) × Usage factor × the number of vehicles equipped with the KOITO Groupʼs LED headlamps
*Power consumption differences between LED headlamps and halogen headlamps.

*The calculations are based on our standards, referring to the Ministry of the Environment's guidelines, etc.
The "environmental preservation effects" and "economic effects of environmental preservation measures" are calculated based on the direct effects brought about by the investment and cost of environmental preservation costs.
Environmental preservation costs and effects of domestic affiliates that are mainly engaged in manufacturing are only those that can be clearly identified as costs spent on environmental preservation.
