Some time ago, the choice of real eco resorts and lodges was limited to the Amazon jungle or remote locations in Sub-Saharan Africa. Nowadays the modern traveller is spoilt for choice with an abundance of environmentally responsible and sustainable locations to choose from. Here we present five of the top eco resorts worldwide that boast some of the best renewable technologies, making them true green stays.

1. Umlani Bushcamp, South Africa

The Umlani Bushcamp provides the authentic South African experience within the framework of sustainable tourism and environmental responsibility. Part of the Kruger National Park, the owners have made a concentrated effort to ensure the materials used in the construction of the camp remain true to the surroundings. With experienced staff on site to give guests the best understanding of the local area, including the abundant wildlife, the Umlani Bushcamp is a wonderful choice for those wanting a traditional African feel. With 100% recycling, lead-free paint, organically grown vegetables and water conservation policies the lodge is committed to reducing its footprint. A massive 70% of the energy used at the lodge is generated through solar power, which provides hot water throughout the year. By staying at Umlani guests can be assured they are doing their bit for responsible tourism.

• Prices start at R1996 per person sharing ($295)

2. Saadani Safari Lodge, Tanzania

Situated on the edge of the Indian Ocean the Saadani Safari Eco Lodge is a true gem. Committed to conserving the natural beauty of the surrounding national park, the owners offer a range of initiatives to support the local community, and expect their guests to get involved! A water mill has been built, which provides water to the nearby village and also provides a small salary for a local maintenance technician. The lodge has been helping local tribes to make charcoal from sustainable resources and not from log burning, which was their usual practice. A biogas burner on site provides fuel to the lodge, and proceeds from takings are being used to build an ecofriendly lodge for the village. This is ecotourism in the true sense of the word, as the lodge uses renewable and sustainable resources to not only sustain itself, but also the local community.

• Prices available on request from Saadani Lodge.
