The community living on the Scottish Isle of Eigg were the first in the world to set up their own off-grid energy system powered by wind, water and the Sun. The tiny island has shown it’s possible to rely almost entirely on renewables. Since it was launched in 2008, they have received visitors from several other countries wanting to learn more about the project. Community Energy Malawi, who help to set up renewable energy systems across Malawi, used their experience to set up a solar minigrid in Sitolo village, a community that previously relied on fossil fuels and firewood.
The warmer it gets, the more people use air conditioning—but the more people use air conditioning, the warmer it gets. Is there any way out of this trap?

The Belize Barrier Reef System features three of four coral atolls in the Atlantic, lush mangrove forests, numerous offshore islands, and one of the most extensive seagrass areas in the Caribbean. It hosts 77 species listed as threatened by the IUCN, including a sizeable population of West Indian Manatees.
Now, Belize has reaffirmed its environmental leadership by becoming the first country in the Americas to finalize a debt conversion for ocean conservation—and one that represents an impact investment for marine protection that’s unprecedented in scale. This commitment will enable Belize to restructure approximately US$550 million of external commercial debt—an amount that represents 30 percent of the country’s GDP—and reduce the national debt by 12 percent.
The seagrass meadows around the Maldives are under threat. But the government now plans to place this valuable ecosystem under protection. As well as serving as nurseries for sea life, they act as carbon sinks and protect the atolls from erosion.
Maldives, officially the Republic of Maldives, is an archipelagic state in the Indian subcontinent of Asia, situated in the Indian Ocean. It lies southwest of Sri Lanka and India, about 750 kilometres from the Asian continent’s mainland.
Pawel Rymsza’s proposal to house humanity in a network of ring-shaped structures built around huge algae-rich lakes is the first of 15 visionary projects shortlisted for the Redesign the World competition powered by Twinmotion.
Called Carbon Neutral Rings, Rymsz’s proposal is to create a network of enclosed carbon-neutral cities for humanity to live in. Each ring is built around a huge reservoir of algae, which would be used to filter the air inside the rings and act as a carbon sink to absorb the city’s emissions.
The carbon dioxide absorbed by reservoirs would ensure the cities are carbon-neutral initially and would become carbon-negative over time as humanity shifts to less carbon-intensive technologies.
Redesign the World is the ultimate design competition, which called for new ideas to rethink planet Earth to ensure that it remains habitable long into the future. Launched in partnership with Epic Games, the contest asked entrants to visualise their concepts using architectural visualisation software Twinmotion.
The towering trees in Gabon’s mangrove swamps have helped to make the Central African country one of the world’s few net absorbers of carbon. However, many are under threat from urbanization, with former swamps being illegally cleared for construction.
Over one-third of greenhouse-gas emissions come from food production. For a greener future, this urgently needs to change. What’s the future of food in a more sustainable world? Our experts answer your questions.
