Lifestyle Changes and Their Impact on Sustainability

The way we live – what we eat, how we commute, what we buy, and how much energy we use – has a direct impact on the planet. Over the past few decades, rising incomes and rapid urbanisation across the developing world have dramatically reshaped consumption patterns. Billions of people are entering the global consumer class, and their lifestyle choices are creating new sustainability challenges. Understanding the link between changing lifestyles and sustainability is essential for anyone interested in building a more resource-efficient future.

The rise of the global consumer class 🔗

The term “global consumer class” refers to the growing population of people whose incomes are high enough to support discretionary spending – purchases beyond basic food, shelter, and clothing. According to Brookings Institution research, Asia has been the primary engine of middle-class growth since 2000. The continent is now home to the world’s largest consumer market in terms of both population and spending. By 2024, projections suggested that over half of all Asians would qualify as middle class or above.

This expansion is not just about numbers. As McKinsey Global Institute research noted, in the year 2000, only about 15 percent of Asia’s population belonged to the consuming class. By 2020, the share of the global consumer class located in Asia had reached roughly 50 percent, and the share held by OECD countries had halved. In the next decade, consumption growth in Asia is expected to come predominantly from people already in the consumer class moving into higher income brackets, rather than from new entrants alone.

What does this mean for sustainability? As hundreds of millions of urban consumers in countries like China, India, and Indonesia adopt lifestyles that mirror those historically seen in North America and Europe, demand for energy, water, food, and manufactured goods surges. This places enormous pressure on finite natural resources. One widely cited figure from the UN Environment Programme notes that humanity is already consuming 1.6 planet’s worth of resources each year, and this rate continues to climb as the global consumer class expands.

Economic shifts driving consumption 🔗

Many developing nations are undergoing a structural economic transition – moving from agriculture-based economies to industrial and service-oriented ones. This shift has profound implications for energy use and consumption patterns.

Industrialisation and appliance growth 🔗

When countries industrialise, their energy demands rise sharply. Factories require electricity; transport networks expand; and as household incomes grow, families purchase refrigerators, air conditioners, washing machines, and personal vehicles for the first time. According to the World Economic Forum, by 2030, around 70 percent of ASEAN’s population is projected to be middle class, and consumer spending in the region could more than double. This massive growth in purchasing power inevitably drives up resource consumption and emissions.

In China, for example, the economy has shifted dramatically. The share of GDP from primary industry (agriculture) dropped from around 4 percent to just 0.3 percent between 1999 and 2020, while the tertiary (services) sector grew from 57 percent to nearly 84 percent. This restructuring created wealth but also fuelled a surge in energy-intensive consumption by urban households.

The consumption-emission link 🔗

Economic development and rising emissions are closely linked. Research published in Economic Research examining several Asian countries from 1980 to 2014 found that urbanisation and economic growth were associated with higher CO₂ emissions. Industrialisation and transport – both heavily reliant on fossil fuels – were identified as the primary emission drivers across these nations.

Urban versus rural energy use 🔗

There is a stark divide between how urban and rural populations consume energy – and this divide is a key factor in understanding sustainability outcomes in developing countries.

Rural reliance on biomass 🔗

In rural areas of developing nations, biomass – firewood, charcoal, agricultural waste, and animal dung – remains the dominant energy source. According to the International Energy Agency’s World Energy Outlook, around 2.6 billion people in developing countries rely on biomass for cooking. In many countries, biomass accounts for over 90 percent of household energy consumption. In India, roughly 77 percent of rural households depend on biomass for their energy needs; in Nepal, the figure is as high as 92 percent.

While biomass is a renewable resource in principle, it is often harvested unsustainably. This leads to deforestation, soil degradation, and indoor air pollution – a cause of roughly 1.3 million premature deaths annually, predominantly among women and children.

Urban dependence on commercial energy 🔗

Urban areas, by contrast, are heavily dependent on commercial energy – electricity, natural gas, petroleum, and coal. Cities need energy for buildings, transportation, manufacturing, and an expanding array of consumer electronics and appliances. As people migrate from rural areas to cities, they switch from biomass to commercial fuels. This transition reduces indoor air pollution at the household level but significantly increases overall carbon emissions.

The trends, however, are shifting. Government programmes in countries like Iran and India are extending natural gas and LPG connections to rural areas, gradually replacing traditional biomass cooking. Electrification rates in rural areas of many developing countries have risen sharply over the past decade. While this improves living standards and health outcomes, it also integrates rural populations into fossil-fuel-dependent energy systems – adding to aggregate emissions unless accompanied by clean energy investments.

Cultural influences on lifestyle and consumption 🔗

Lifestyle choices are not purely economic decisions – they are deeply shaped by culture, social norms, and identity. Understanding these cultural dimensions is critical to addressing unsustainable consumption.

Material possessions as identity markers 🔗

Across many societies, material goods function as symbols of success, status, and social belonging. A cross-national study covering eight countries found that self-identification with global consumer culture and exposure to global mass media were the most consistent positive drivers of materialism. Importantly, the study also found that materialistic tendencies were compatible with – not opposed to – local cultural identities and traditions.

This finding matters because it challenges the assumption that only “Westernised” populations are materialistic. In rapidly developing economies, aspirational consumption – buying branded clothes, electronics, or cars to signal upward mobility – is widespread. Research by GlobeScan and BBMG identified a segment called “Aspirational” consumers in Asian urban markets. These consumers, representing over 40 percent of urban populations in China and India, combine a love of shopping with a desire for responsible consumption and trust in brands that act in society’s interest.

The role of advertising and media 🔗

Global advertising reinforces materialistic values by promoting themes of luxury, exclusivity, and accumulation. Worldwide, brands use imagery associated with success and glamour to drive purchases. Social media amplifies this effect by curating lifestyles centred on material goods. This makes it difficult for consumers to distinguish genuine needs from commercially manufactured desires – and it fuels overconsumption even in regions where resources are scarce.

As research on sustainable consumption in the Global South has pointed out, prevailing neoliberal economic models valorise aspirations that push notions of the “good life” towards overconsumption. Consumption practices are embedded within a complex mix of values, emotions, self-conception, and cultural associations – making behaviour change far more difficult than simply providing information about sustainability.

Carbon footprints of cities: the urbanisation challenge 🔗

Urbanisation is one of the defining trends of the 21st century, and its environmental consequences are enormous. Cities are responsible for the majority of global greenhouse gas emissions, and the rapid growth of Asian megacities has brought this issue into sharp focus.

Megacities as major emitters 🔗

A landmark study published in Frontiers in Sustainable Cities inventoried greenhouse gas emissions from 167 cities worldwide and found that just 25 mega-cities accounted for 52 percent of total urban emissions. Asian megacities like Shanghai and Tokyo ranked among the highest total emitters. While cities in Europe, the US, and Australia still had higher per capita emissions overall, several Chinese cities had per capita emissions that matched or rivalled those of cities in developed countries.

In China specifically, cities contribute roughly 85 percent of the country’s CO₂ emissions. Urban residents emit about 1.4 times more energy-related CO₂ than rural residents on average. The wealthiest urban populations have carbon footprints nearly four times greater than the national average. Urban agglomerations formed by megacities currently account for approximately 78 percent of China’s GDP and 72 percent of its total carbon emissions.

Density as a double-edged sword 🔗

Interestingly, research from the World Bank has shown that denser cities tend to have lower per capita emissions, even after controlling for income, economic structure, and environmental policy. Shorter commutes, greater reliance on public transport, and more efficient building designs all contribute to this. The implication is that how cities grow matters as much as whether they grow. Allowing megacities to become denser rather than more sprawling could meaningfully reduce urban carbon footprints.

However, this is not automatic. If urbanisation proceeds without investments in public transit, green buildings, and renewable energy, the result is simply more emissions concentrated in smaller areas. The challenge is to steer urban growth towards low-carbon pathways – something that requires proactive policy, not just market forces.

Towards sustainable lifestyles: what needs to change 🔗

Addressing the sustainability challenges posed by changing lifestyles requires action at multiple levels – individual, corporate, and governmental.

Closing the say-do gap 🔗

Consumer surveys consistently show that people care about sustainability. Nearly half of Asia-Pacific consumers say purchasing environmentally friendly products is important to them. Yet follow-through remains limited. Cost, lack of information, and difficulty finding sustainable products are the most commonly cited barriers. Companies and policymakers must make sustainable options more accessible, affordable, and clearly labelled.

Rethinking urban planning 🔗

Cities must be designed with sustainability at their core. This means investing in public transport, energy-efficient buildings, waste reduction infrastructure, and urban green spaces. It also means rethinking zoning laws to encourage denser, mixed-use development rather than car-dependent sprawl.

Shifting cultural narratives 🔗

Perhaps the deepest change required is cultural. If material accumulation continues to be the primary marker of success and identity, no amount of policy intervention will achieve sustainability at scale. Communities, educators, and media can play a role in promoting alternative definitions of well-being – ones that centre experiences, relationships, and environmental stewardship rather than ownership of goods.

What do you think? Can developing economies achieve prosperity without replicating the high-consumption lifestyles of the West? And what role should cultural values play in redefining what a “good life” looks like in the age of climate change?
