The Construction21 users
In Japan, our company is well-known as eco-friendly, energy efficient and reliable. But not abroad. We joined the Green Solutions Awards in 2017 and we were very happy to win a prize: the jury fairly understood what we do in Japan. It was very helpful to communicate with possible clients outside Japan.
[…] There is a beneficial ripple effect to the Green Solutions Awards competition, thanks to all the great opportunities it opened to our company by connecting us with supporting organisations and companies.
