Knight Frank this week announced it had signed a contract with Total Gas and Power to purchase 100% renewable energy for the properties it was managing through to 2021.This initiative alone is expected to reduce its carbon dioxide output by more than 100,000 tonnes by 2021 – “the equivalent of taking nearly 17,000 cars off the road over the course of the contract”, the company says.Regardless of the different options property companies are exploring, one thing is clear: inertia is not an option.

By investing in high-speed rails, electric bus networks, and modernized subways, cities are able to both improve efficiency and cut down on pollution.In Ethiopia, for instance, the first fully electric train system in Africa Many cities clusters around the world have enacted or are exploring options for As cities expand, natural green space gives way to concrete, asphalt, glass, steel, and tar — all the materials that allow millions of people to cluster in a limited area.This transition from a natural to a built environment creates what is known as the “urban heat island effect,” when buildings, streets, and other surfaces absorb and radiate the sunlight, rather than reflect it or use it for energy, causing the local environment One way to mitigate this, cities have found, is to target the surfaces that are most exposed to the sunlight: rooftops.For example, roofs painted white reflect the sunlight, cooling surfaces Rooftop gardens are even more effective because they bring the temperature down, provide shade, clean the air, and don’t just bounce sunlight back into the atmosphere, which could Solar rooftops are even better — they cool the roof and capture the sun’s light for energy. It ends up in landfills, oceans, green spaces, and elsewhere, So efforts to ban plastic are taking off, largely driven by initiatives in cities.
