An employee-participatory social contribution program
"One World One Komatsu"

Komatsu recognizes “contributing to society through our business activities” as part of our corporate social responsibility and engages in initiatives that leverage our business characteristics to benefit local communities. In 2021, the year Komatsu celebrated its 100th anniversary, we launched the "One World One Komatsu" employee-participation social contribution program as the Komatsu Group's first global initiative open to all employees.
The theme of "One World One Komatsu" is "Environment and Sustainability," which is a common issue around the world and has a high affinity with our business, and each and every employee will take part in activities that are familiar to them in their daily lives, such as "reducing water consumption" and "turning off lights in unused rooms.
In order to promote these activities, we have set up a dedicated platform that allows the entire group to consolidate the activities of each individual. This new platform can be easily logged in from a PC or smartphone. Komatsu will continue to promote activities for a sustainable planet by fostering a sense of unity among Komatsu Group employees around the world, transcending differences in countries and languages, and working toward a common goal.

Four priority themes of "One World One Komatsu”

Reduction of CO2 emission
Water conservation
Renewable energy
Reduction of waste

Eliecer Jovani Sandoval Rodríguez, Komatsu Chile S.A.

Award Category:Diversity & Inclusion

Supporting special needs children through sport

Through his CLUB LKF, Eliecer offers boxing and kickboxing workshops for socially vulnerable children who are often denied access to sporting spaces because of their limited resources or perceived disabilities, including Down syndrome, autism spectrum diagnoses and mental illness. Through the power of sport and discipline it entails, Eliecer said, he has seen children emerge from depression and improve their daily lives, providing an outlet that has a great ripple effect for the community by creating true diversity, equality and inclusion.

Kathryn Kauffman, Komatsu North America Corp.

Award Category:Community Development

Science, art and technology kits support local students

This Covid era-inspired project started with 70 marshmallow launcher kits for local students. Today, Kathryn and her team have expanded their effort to include an estimated 100 fifth graders alone, using 100 percent recyclable kits focused on the One World One Komatsu mission of sustainability. Each STEAM kit (Science, Technology, Engineering, Art and Mathematics) includes supplies and instructions for a science experiment, as well as wildflower seeds to support local pollinators, a handout with information on sustainability and Komatsu stickers. The handout publisher also uses recycled materials and plants trees for each kit order.

Agustin Ramos Aguilar, Komatsu Forest AB, Brazil

Award Category:Sustainable Solutions

Family passion supports orchid conservation and research

A family passion spanning 40 years blossomed into this one-of-a-kind conservation project focused on mapping, studying and rescuing orchids, which are under threat of reforestation, excessive harvesting and climate change. Partnering with universities in Mexico and Brazil, Agustín’s project grew from trips into forest into an academic effort to produce digital files to aide in species identification, reproduce seeds from vulnerable species, developing a smart greenhouse system — all while discovering new orchid species and building a nature preserve on the family ranch.

Sebastian Guevara Diaz, Komatsu Colombia S.A.S.

Award Category:Carbon Conscious

Contributing to CO2 reduction through tree planting

Sebastian’s submission underscores the “small actions, big impact” tenet of One World, One Komatsu in a project that generated a clear and profound impact. He planted 50 trees, helping remove more than 500 kilograms of carbon dioxide from the air while putting in many hours of volunteer work. As Sebastian said, “(This) is not just a number; it is a cleaner future, it is fresher air, better views, a feeling that you are contributing and connecting with life that cannot be described.”

Olivia Ratner, Komatsu Europe International N.V. 

Award Category:Water Wise

Saving water through timed showers, water re-use and habit tracking

Olivia took 110 five-minute showers over five months. But, more than that, she learned the source of her household water, calculated water tank capacity and the cost to generate that supply, and charted refill time to boost efficiency. Over five months, she took lessons from her data — and practice of using grey water for plants and mopping — and then shared with her husband and houseguests to amplify her impact.

Christina Milde, Komatsu Germany GmbH

Award Category:Energy Enthusiast

Renewable energy home renovation supports sustainability

Christina turned a home renovation project into a sustainability opportunity. Combining technology and energy management, including energy-efficient windows, home insulation, an earth-based heat pump power by solar panels, smart appliances and an energy monitoring system, the combined effect will result in energy savings for years to come, reduce their household environmental footprint and serve as an example for friends and family to do the same.

Piyush Paratkar, Komatsu India Pvt. Ltd.

Award Category:Waste Watcher

Trash pick-ups, recycling, litter prevention: Small actions, big impact

Through weekly trash pick-ups, Piyush and his Nagpur Ploggers volunteer team collected 780 kilograms of plastic waste, 1.8 kilograms of cigarette butts, 770 plastic bottles and 490 glass containers. They also worked with local schools to turn 600 kilograms of plastic waste into 2,400 eco-bricks and used funding from Komatsu to establish a JUMBO trash bin project, leading to 15 giant trash bins installed in public spaces in Nagpur. Finally, their Chalk of Shame initiative, which combined chalk circles to identify litter and messages for people who discarded trash, was an innovative, artistic and non-confrontational way to deter littering.

Mirco Battistella, Komatsu Italia Manufacturing S.p.A.

Award Category:Volunteer of the year

Community builds teamwork, pioneers new inclusive sport

As the organizer of Polisportiva Redentore Este, Mirco works with about 100 volunteers and 500 athletes, providing a powerful tool for inclusion and integration in the community of Este. The young athletes of Polisportiva can play a variety of games and athletics, including the newest sport, baskin. A combination of the words “basketball” and “integration,” baskin brings disabled and able-bodied players together.
