The invasion of polar bears, the chaos in Australia, the flood of Svalbard global seed vault…All these visible damages prove that the impacts of global warming of 1ºC is already terrible. The increasing risks and devastating disasters of nature unbalancing warn us that we’re the one who break the rule.
In 2018, an IPCC special report of global warming of 1.5 ºC officially advocated that global warming must be kept to a maximum of 1.5℃ within 12 years. To achieve the 1.5ºC pathway, a 45% decrease in global net anthropogenic CO2 emissions from 2010 level by 2030, reaching net zero around 2050, is needed.
It’s an urgent revolution of the whole society, and building industry is the main force. Because building sector, construction and operation together, account for nearly 40% of energy-related carbon dioxide emissions. Only the energy intensity per square meter of the global building sector decreases on average by 30% by 2030 (compared to 2015), we can meet the global climate ambitions within 12 years.
