The world needs real action on climate change now. 

• "Cities account for 3 percent of the world’s built-up land, but they are home to more than half the world’s population. Due to the population density, cities consume more than two-thirds of the energy worldwide and account for approximately 70 percent of CO2 emissions. According to a United Nation's report, buildings, and construction account for 39 percent of global carbon emissions. If global population continues increasing by 2.5 billion until 2050 and developing countries increase their urban land cover to current global averages, the production of infrastructure materials alone is projected to generate approximately 470 billion metric tons of CO2 emissions" - HACKFOREARTH

• Urban infrastructure and public infrastructure is important for development of any city which includes pavements, roads, public toilets, hospitals and so much more. 

• The world’s natural capital – water, land, forests, soil, wildlife, and fisheries – safeguards and underpins the health and well-being of billions of people. In low-income countries in particular, populations rely on these resources for half of all wealth, including long-term economic growth, livelihood opportunities, and the ecosystem services that support human well-being. The changing climate increases the importance of sustainable natural resource management, which often bolsters resilience. At the same time, natural resources experience both additional stress from the extreme weather conditions associated with climate change and need to decrease emissions in order to achieve lasting and feasible net-zero and climate-resilient pathways. 

• Digital innovations offer unprecedented opportunities as key enablers for the economy’s green transition. 

• Behaviour and community action is pertinant to drive green transition and technology and digital solution can help accelerate this transition.
