Most of us spend a large chunk of our lives in one building or another, but have you ever stopped to consider the greenhouse gases linked to the construction of these buildings?
One way to reduce greenhouse gases is the use of recycled and more environmentally friendly building materials.
The United Nations Environment Programme (UNEP) International Resource Panel has just published a recent report titled Resource Efficiency and Climate Change: Material Efficiency Strategies for a Low-Carbon Future. Commissioned by the G7 countries, it shows that natural resource extraction and processing account for more than 90 per cent of global biodiversity loss and water stress, and around half of global greenhouse gas emissions.
The findings point to opportunities to reduce these impacts through material efficiencies in homes and cars.
According to the Panel’s modelling, emissions from the material cycle of residential buildings in the G7 and China could be reduced by at least 80 per cent in 2050 through a series of material efficiency strategies.
A design with fewer or alternative materials, and more recycling of construction materials are among the most promising strategies, it says.
More concretely, the Panel’s modeling tells us that within the buildings and construction sector, we could reduce greenhouse gas emissions by 350 million tonnes in China; 270 million tonnes in India, and 170 million tonnes in G7 countries, between 2016 and 2060.
“Policy intervention from different angles is required to achieve these savings,” says the head of UNEP’s Cities Unit, Martina Otto.
“Policies can influence how people live, which materials they use and how they use them. Instruments such as taxation, zoning and land use regulation play a role, but so do consumer preferences and behaviour.Building codes and standards drive building performance and connect building design to policy. They can encourage or constrain material efficiency and circularity.”
According to the 2019 Global Status Report for Buildings and Construction, almost 40 per cent of energy-related greenhouse gas emissions are from the buildings and construction sector.
”In the buildings and construction sector, much attention was concentrated on ‘operational energy efficiency’, the energy used in buildings and which can be influenced by building design, insulation, passive solutions for heating and cooling, appliances and systems improvements as well as maintenance and usage,” says Otto. “But we also need to look at materials to reduce pressure on natural resources and ‘embodied carbon’.” Embodied carbon is the amount of carbon (CO2 or CO2 emission) to produce a material.
Building design and the use of recycled and alternative materials
In G7 countries, material efficiency strategies, including the use of recycled materials, could reduce greenhouse gas emissions in the material cycle of residential buildings by 80 to 100 per cent in 2050, the Panel’s report suggests. Potential reductions in China could amount to 80 to 100 per cent, and to 50 to 70 per cent in India in 2050.
“There are many different options. For example, sustainably managed and harvested timber has the potential to reduce greenhouse gas emissions by 1 to 8 per cent in 2050 in the G7,” says Otto. “There are also a variety of new products, for example from agricultural waste, that could help close loops towards circularity. Choices need to be locally appropriate and include sustainability considerations.
“Designing buildings using less material (savings of 8 to 10 per cent in 2050 in the G7, according to the Panel’s report) is another thing to look at, alongside passive cooling and heating and natural light to reduce operational energy at the same time.”
The consumption angle
Measures with the highest impact and lowest cost include getting greater use out of buildings for more hours per day and extending the lifetime of buildings (the Panel says up to 70 per cent savings could be achieved by 2050 in the G7).
Improved recycling could reduce greenhouse gases by 14 to 18 per cent in 2050 in the G7. Overall, cumulative savings in the period 2016–2050 from these strategies in the G7 would amount to 5 to 7 gigatonnes of CO2 equivalent, says the report.
Looking at the whole building life cycle, material efficiency strategies could reduce emissions in 2050 from the construction, operations and dismantling of homes by 35 to 40 per cent in the G7. Analogous savings could be up to 50 to 70 per cent in China and India.
“Virgin material taxation and removal of virgin resource subsidies should be key options for policymakers,” says Otto. The Global ABC Roadmaps 2020–2050 provide targets and timelines to achieve zero-emissions, efficient and resilient buildings and construction.
The world must immediately begin to deliver faster greenhouse gas emission cuts to keep global temperature rise to 1.5°C, says the November 2019 edition of UNEP’s Emissions Gap Report.
“To achieve this goal, we will need to use the full range of emission reduction options. We need progress in all sectors: energy, industry, agriculture, forestry, transportation and buildings, better integration across sectors, and urban planning and design to meet this target,” says Otto.

Cities at Centre of International Initiative to Add Jobs and Protect the Planet
Cities are engines of growth, contributing some 80% to global GDP, but they also account for 75% of global greenhouse gas emissions. Even in a post-COVID-19 future, urbanization is expected to grow. Cities, suburbs and the global infrastructure system have a great impact on nature, yet their role in protecting biodiversity loss and mitigating climate change has been underestimated, until now.
To help transform cities into engines of economic growth compatible with planetary and human well-being, the World Economic Forum is collaborating with the government of Colombia and the Alexander von Humboldt Institute for Research on Biological Resources on a new global initiative, BiodiverCities by 2030. This initiative will help cities around the world unlock opportunities for urban growth while protecting the environment.
In order to shape a nature-positive future, the initiative is curating a high-level commission of 25 world-renowned experts and practitioners from government, the private sector, academia and civil society. The Global Commission on BiodiverCities by 2030 will build a shared, framework and forward-looking perspective on the BiodiverCities concept.
The publicly accessible framework will outline how cities can shift from the current untenable relationship with rural areas and natural resource assets towards a more nature-positive model, which, research indicates, can add jobs to the economy. On the back of this knowledge framework, the initiative will also build on the Forum’s Strategic Intelligence platform and on a community of innovators and entrepreneurs in close partnership with the World Economic Forum’s UpLink platform.
As President Duque stated, “Colombia is the world’s most biodiverse country by square kilometer, and we have the challenge and the responsibility to protect nature in cities while improving people’s wellbeing. We are excited to partner with the World Economic Forum and key international actors to help shape a much-needed global agenda on BiodiverCities. Building on our produce while conserving and conserve while producing policy, we are eager to both share Colombian cities’ efforts and experiences, and to learn from valuable international knowledge and best practices.”
Klaus Schwab, Founder and Executive Chairman of the World Economic Forum, said: “COVID-19’s impact is a stark reminder of our imbalance with the natural world. As cities face the enormous task of recovering from the impact of the COVID-19 pandemic, BiodiverCities by 2030 aims to show how nature-positive cities can offer transformative opportunities for the benefit of people, planet, health and livelihoods. We greatly look forward to working with the President of Colombia and other partners on this important global initiative and connecting with a community of experts, mayors and policy-makers.”
Research shows that nature-positive solutions, or those that add value back into nature, can create healthier and more resilient cities while generating $3 trillion in business opportunities and creating 117 million jobs. “Cities can be cooler in the summer, have cleaner air and be better protected against flooding if we can put nature at the heart of its development model,” said Akanksha Khatri, Head of the Nature Action Agenda, World Economic Forum.
At the World Economic Forum’s Sustainable Development Impact Summit 2020, and during the United Nations General Assembly meeting, President Duque called for a broader effort to advance cities and sustainable development through a “BiodiverCities” approach.
A network of nine Colombian cities, including Barranquilla as one of the initial pilots, aims to include biodiversity in their urban development models and to promote the interaction of citizens with nature. The Ministry of the Environment and Sustainable Development of Colombia is leading efforts to pilot this initiative with support by the World Resources Institute and the Alexander von Humboldt Institute for Research on Biological Resources.
BiodiverCities by 2030 comes at a vital moment. The COVID-19 pandemic has challenged assumptions about work, transportation and city living; and, nature-positive cities can offer transformative opportunities for the benefit of people, planet, health and livelihoods.This new global initiative and partnership between the World Economic Forum and Colombia will promote cities’ potential to drive pro-biodiversity urban growth.
Cities Are Key to India’s Post-Pandemic Growth
The unfolding COVID-19 pandemic has been catastrophic for cities, which have borne the brunt of the outbreak. According to estimates, about 70% of India’s GDP comes from its cities and around 25-30 people migrate to the cities from rural areas every minute. However, most big cities in India have wide economic disparity, with expansive slums and a large urban poor population. Studies estimate that about 25 million households in India – 35% of all urban households – cannot afford housing at market prices. It is time to create a new urban paradigm that enables cities to be healthier, more inclusive and more resilient.
The World Economic Forum’s new report, Indian Cities in the Post-Pandemic World, highlights the country’s most pressing urban challenges that were further exacerbated by the pandemic. The report provides insights for translating the lessons learned from the pandemic into an urban reform agenda.
The impact of the pandemic has been profoundly uneven on different population groups. Vulnerable populations, including low-income migrant workers, have suffered the dual blows of lost income and weak social-protection coverage. The pandemic has also laid bare gender-based imbalances in public and private life in India’s urban areas.
The report, produced in collaboration with the IDFC Institute in Mumbai, compiles insights from leading global and Indian urban experts across seven thematic pillars: planning, housing, transport, environment, public health, gender and vulnerable populations.
Among other recommendations, the report underscores the critical role data can play in helping cities manage and direct emergency operations during a crisis. But data alone is not a panacea; realizing the potential of cities requires empowered and capable governance, investment in transport and infrastructure to fuel productive urban economies, and a rethink of outdated planning norms and regulations.
The wide-ranging recommendations compiled in the report include:
· A rethink of outdated urban planning regulations, which will make cities more compact, commuter-friendly and green
· Greater decentralization and empowerment of local governments, which will allow for more proximate and responsive governance
· Addressing supply-side constraints to building houses at an affordable cost and encouraging a vibrant rental housing market that allows for labour mobility
· Investing in transport solutions that recognize the need to integrate peri-urban areas with urban cores
· Bolstering health capacity in cities by increasing the number of trained healthcare personnel; ensuring that infrastructure has adequate functional capacity, aligned with current and future demands
· Prioritizing inclusivity by addressing the biases and impediments faced by women and vulnerable populations in accessing urban opportunities
· Prioritizing action on environmental sustainability, air pollution and disaster management in urban rebuilding efforts
“Well-designed and governed cities can be dynamic centres that spur innovation, drive economic productivity and provide citizens with a good quality of life. The pandemic is an opportunity to address historical urban challenges and bring about positive long‑term change,” said Viraj Mehta, Head of India and South Asia and Member of the Executive Committee, World Economic Forum.
“Amidst every pandemic, from the bubonic plague to the Spanish flu, pundits have foretold the death of cities. And yet they have emerged stronger every time. The pandemic can be a turning point in India’s urban journey, if we draw the right lessons and translate them into lasting change,” said Reuben Abraham, Chief Executive Officer and Senior Fellow, IDFC Institute.
The Indian Cities in the Post-Pandemic World report is part of the World Economic Forum’s broader collaboration with the IDFC Institute for a working group on Rebuilding Cities which has emerged from the Regional Action Group for South Asia. This group brings together public and private sector leaders and prominent experts from the region to interact regularly in order to support an adequate public-private response to the COVID-19 pandemic and jointly chart recovery efforts.
The working group on Rebuilding Cities is partnering with multiple Indian state governments to constitute state-level working committees comprising local/municipal government representatives, urban experts and other relevant stakeholders to devise implementable and context-specific urban reform recommendations.
