United Nations, Dec 8: United Nations environment agency (UNEP) co-released a report at the COP24 climate conference in Katowice which says the greener construction is the future of the world. The report appreciates the progress in greening the global construction industry, but poses concern over the alarm on the need for “dramatic action” to reduce the sector’s greenhouse gas emissions.
“It’s critical we have a big change over the next couple of years in how we do buildings and construction”, said Joyce Msuya, Deputy Executive Director of UNEP. “We only need to look at the current norms and quality of many buildings to see that we can do so much better,” she said, emphasising that “we need to raise the bar in energy-efficient, green buildings and far better practice in construction.”
Currently, buildings account for close to 40 per cent of the world’s greenhouse gas emissions and 36 per cent of all energy consumption. In the report, which was co-authored by the International Energy Agency (IEA), UNEP warned that “dramatic action will be needed by governments, cities and business if the global buildings and construction sector is to cut its carbon footprint in line with international agreements.”
Titled ‘Towards a Zero-Emission, Efficient and Resilient Buildings and Construction Sector’, the report was presented against the backdrop of ongoing COP24 negotiations on how to move ahead with the implementation of the climate action agreement adopted in Paris, in 2015, when 197 parties committed to limiting global warming to 1.5°C above pre-industrial levels.
The development of new techniques, tools, products and technologies, such as heat pumps, better windows, stronger insulation, energy-efficient appliances, renewable energy and smarter design – has enabled emissions to stabilize over the past few years.
There are other encouraging signs. Several property, construction, cement and steel-manufacturing firms are among the 500 companies (representing trillions of dollars in revenue) which have aligned their emission reduction targets with the Paris Agreement; and the 71-member private sector network, the World Green Building Council non-profit organization, is advocating for all buildings to emit zero net emissions by 2050.
There is huge potential to reduce the current level of emissions, but action has been too slow, environmentalists say. To meet the goals of the Paris Agreement, the Global Alliance for Buildings and Construction, hosted by UNEP, is targeting a 30 per cent energy use improvement in the buildings and construction sector.
