Pursuing Environmental Management  Environmental Action Plan and Results for FY2014 (Research and Development)

Reduce the environmental impact of construction equipment

·Develop low-emission construction equipment (compliant to emission standards)
Objectives for FY2014 Results for FY2014 Medium- and long-term objectives
Develop vehicles compliant with Tier4 emission standards ·Developed vehicles equipped with engines compliant with Tier4 final emission standards (PC210LC-11, D85EX/PX-18, HM300-5, etc.) Development of Tier4 final (STAGE IV) emission standard compliant vehicle in Japan, US, and EU by 2014

·Reduce CO2 emissions from construction equipment (improve fuel efficiency of products)
Objectives for FY2014 Results for FY2014 Medium- and long-term objectives
Reduction in emissions with Tier4 emission standard (Hydraulic excavators: 10-13% reduction compared to Tier3)
  • ·Achieved 14% to 15% reduction in emissions with vehicles complaint to Tier4 final emission standards (PC210LC-11, PC360LC-11)
Decrease emissions by 10% from Tier4 standard compliant vehicles (hydraulic excavators) by FY2015
Reduction in emissions with hybrid vehicle (Hydraulic excavators: 25-35% reduction in emissions compared to current Tier3-normal vehicles) ·Development of Tier4 final compliant hydraulic excavator (under development) Decrease emissions by 35% from Tier4 standard compliant hybrid vehicles (hydraulic excavators) by FY2015

·Reduce CO2 Emissions from construction equipment (Biodiesel Fuel (BDF) measures: Carbon Offset)
Objectives for FY2014 Results for FY2014 Medium- and long-term objectives
B5/B7 mixed light oil measures
  • ·B20 mixed light oil measure
    (be in progress)
Use of B20, light oil blended with BDF (standard construction equipment)

·Improving recyclability rate of construction equipment
Objectives for FY2014 Results for FY2014 Medium- and long-term objectives
Achieve 99% for recyclability rate equipment compliant with the next developed vehicles
  • ·Achieved 99% recyclability with Tier4 compliant vehicles
Achieve recyclability rate of 99.5±0.5%

·Strictly control and reduce substances of environmental concern in construction equipment
Objectives for FY2014 Results for FY2014 Medium- and long-term objectives
Maintain reduction of hazardous substances at 75% reduction compared to 1998 levels
  • ·Maintained 80% reduction of hazardous substances with newly developed vehicles as compared to 1998 levels
    ·Additional reduction of lead usage in crawler type construction equipment (active)
Reduce lead usage by 90% as compared to 1998 levels by 2017
Reduce the use of lead in vehicles compliant with Tier4 emission standards
  • ·Policy made to ban lead solder usage in the vehicles to be developed for the subsequent periods in principle (except those on-board) from 2015
-
Utilize a separate hazardous substances control system for each product type (to comply with REACH regulations)
  • ·Registered additional new 10 substances of SVHC under the EU REACH regulation, and controlled the usage of those SVHC substances. Conducted surveys of substances for EU destination models and EU mass production and development models (Implementation of component-specific substance surveys)
    ·The control system is being deployed in other overseas countries (other than EU)
Manage substances of each component pursuant with new data
