Most trees planted simultaneously• Most trees planted simultaneously (multiple locations) - The most trees planted simultaneously at multiple locations is 2,294,629, achieved by 122,168 participants in an event organised by TreeVolution: Greening MindaNOW (Philippines), at 29 locations across the Philippines on 26 September 2014. This record-breaking event saw the planting of rubber, cacao, coffee, timber and mahogany trees, as well as a range of fruit trees and other species indigenous to the Philippines.

Largest solar-powered boat - Tûranor PlanetSolar, pictured at the top of the page, measures 31 m (101 ft) long – or 35 m (114 ft) with flaps extended. It has a beam, or width, of 15 m (49 ft) – 23 m (75 ft) with flaps – and a displacement of 85 tonnes (93 tons). The catamaran's upper surface is covered in 537 m2 (5,780 ft2) of solar panels, allowing the vessel to be powered by solar energy alone.

Highest-capacity wind farm - Covering an area of almost 400 km 2 (100,000 acres), Roscoe Wind Farm in Texas, USA, has 627 wind turbines and can generate up to 781.5 megawatts (MW) of power.

Greenest City – Masdar City in Abu Dhabi, UAE, designed by the British architect firm Foster and Partners, is the world’s first city designed to be low-carbon and low-waste. All of its power is generated from renewable resources, and most waste material is recycled. The city favors electric, hybrid, and driverless underground vehicles, so the city’s projected 50,000 citizens should leave little carbon footprint


Largest sculpture of plastic bags - The largest sculpture made of plastic bags consists of 68,000 plastic bags in the shape of an octopus. The sculpture was constructed by over 200 student volunteers for the Ci Yuan Community Centre Youth Executive Committee (Singapore) at the National Youth EnvirOlympics Challenge, Singapore, on 20-21 April 2012.

The WWF is a truly global network, working in more than 90 countries.
