05 Jun 08. The United Kingdom Hydrographic Office (UKHO) has been embracing a range of environmentally friendly activities this week (2nd June – 6th June). The UKHO, which is a Trading Fund owned by the Ministry of Defence, held an Eco Hydro Week to put the spotlight on green issues to coincide with World Environment Day on June 5th. The producer of nautical charts, products and services for the Royal Navy and international mariner staged a variety of activities to encourage staff to be more environmentally friendly and to highlight the work UKHO is doing to reduce its carbon footprint. The week of activities is part of UKHO’s Eco Hydro initiative to meet MoD sustainability targets which state all departments must become a zero waste to landfill organisation by 2020 and recycling levels must improve by a minimum of 8% per year.
