The world’s population is 7.6 billion (UN, 2017) and a large part of it is concentrated in cities, which contribute the most to greenhouse gas (GHG) emissions and, at the same time, offer the best hope for reducing the ecological footprint on a global scale.
Improved urban planning and management is therefore needed to make these spaces more inclusive, safe, resilient and sustainable, as called for in Goal 11 of the Sustainable Development Goals adopted by the UN in 2015.
Singapore is the most sustainable city in Asia and the second most sustainable in the world. Its population is estimated to exceed 6 million inhabitants by 2030 and, as a result, the government has focused on improving mobility and connectivity within the city and has set itself the ambitious goal of making at least 80% of its buildings green by that date.

A green roof, green roof or living roof is the roof of a building that is partially or completely covered with vegetation, either in soil or in a suitable growing medium, with an impermeable membrane. It may include other layers that serve for drainage and irrigation and as a barrier to roots. It may include other layers that serve for drainage and irrigation and as a root barrier.[1
It does not refer to green roofs, such as those with green shingles, nor does it refer to roofs with container gardens. It refers instead to technologies used on roofs to improve habitat or save energy consumption, i.e. technologies that serve an ecological function. Rooftop ponds are another form of green roof used to treat greywater. The green roof is made up of the vegetation, soil, drainage layers, roof waterproofing barriers, and irrigation system. Modern green roofs deliberately placed on roofs that have a green roof are also known as “green roofs.” Modern green roofs are also known as “green roofs.” Modern green roofs are used to treat greywater.
Modern green roofs deliberately placed to maintain vegetation in a growing environment are a relatively recent phenomenon. However Scandinavian countries have used grass roofs for many centuries. The modern trend began when Germany developed the first ones in the 1960s and they have now spread to many countries. It is estimated that about 10% of roofs in Germany are green. They are becoming popular in Europe and to a lesser extent in the United States.

The 10,059 cases of omicron identified on Saturday – up from 3,201 on Friday – brings the total number of people affected by the disease in the country to 24,968, according to figures compiled by Sky News.
“The increase in cases of the omicron variant in our capital is very worrying, so once again we declare the situation of ‘major incident’ due to the threat of the coronavirus to our city,” the mayor has made known.
With these data and in the absence of today’s balance, the country is now close to 11.2 million infected and has more than 147,000 deaths since the beginning of the crisis, according to the balance provided by the Ministry of Health of the United Kingdom on its web page.

At the same time, pressure is mounting on world leaders ahead of the COP26 international climate talks to rapidly reduce the use of fossil fuels, including natural gas. Gas shortages and the sense of urgency around the climate crisis have raised an important question: Is there a better way to heat our homes?
As gas prices soar, some countries have had to restart coal plants to fill the gap in electricity production. But there are cleaner alternatives to heat your home.
Heat pumps: They are becoming a popular alternative. There are two main types: air-source heat pumps, which draw heat from the air, and ground-source heat pumps, which draw heat from the ground, and both essentially work like the opposite of a refrigerator.
“If the government wants a chance to catch up, it needs a proper strategy and enough cash to clean up our homes on a large scale. This means substantial subsidies for heat pump installations, especially for poorer households, removing VAT on green homes and a phase-out of gas boilers early in the next decade,” said Greenpeace UK policy director Doug Parr.
