Household Environmental Footprints

Source: Analysing local environmental footprints (The Hindu, May 22, 2024)

Understanding how household consumption habits impact the environment is crucial for addressing climate change and local environmental issues. A recent study investigates the environmental footprint of Indian households across economic classes, focusing on the impact of luxury consumption on water use, air pollution, and CO2 emissions.

Remember This

Local Issues: Water scarcity and air pollution are local problems.

Household Footprints: Understanding these is key for local environmental action.

Study Focus: Examines the impact of luxury consumption in affluent Indian households.

Luxury Consumption: Includes dining out, vacations, furniture, and social events.

Method: Uses input/output analysis to link consumption to environmental impacts.

Wealth and Footprints: Richer households have larger environmental footprints.

Decile Impact: Top 10% households significantly increase air pollution, water, and CO2 footprints.

Key Contributors: Major impacts from eating out, personal goods, and fruits/nuts.

Energy Use: Transition from biomass to LPG reduces but doesn’t eliminate footprints.

Policy Needs: Target affluent consumption to meet sustainability and justice goals.

Local Environmental Issues

Climate change is a global concern.
Issues like water scarcity and air pollution are often local.
Excessive water use in one region doesn’t affect others.
Local environmental issues are crucial to address.
Household environmental footprints are important to understand.

Household Environmental Footprints in India

A study titled “Water, air pollution and carbon footprints of conspicuous/luxury consumption in India” examines this.
It highlights the environmental impact of affluent individuals.
Focuses on CO2, water, and PM2.5 footprints of luxury consumption.
Luxury consumption includes dining out, vacations, furniture, and social events.

Methodology of the Study

Used an input/output analysis of the entire economy.
Linked household consumption to production resources.
Quantified water usage at different production stages.
PM2.5 footprint included embedded and direct emissions.
CO2 footprint included both embedded and direct emissions.

Key Findings

Environmental footprints increase with household wealth.
Richest 10% have double the average environmental footprint.
Air pollution footprint rises 68% from the ninth to the 10th decile.
Water footprint rises 39%, and CO2 emissions rise 55%.
Top decile households have significant luxury consumption impacts.

Key Contributors to Environmental Footprints

Eating out is a major contributor to all footprints in the top decile.
Fruits and nuts increase the water footprint in the 10th decile.
Personal goods, jewellery, and eating out increase CO2 and air pollution.
Poorer households using fuels like firewood contrast with modern energy impacts.
Transitioning from biomass to LPG reduces direct footprints but affluent lifestyles increase PM2.5 and CO2 footprints.

CO2 Footprint of Top Decile

Top decile’s CO2 footprint is 6.7 tonnes per capita per year.
This is higher than the global average of 4.7 tonnes in 2010.
Much higher than the 1.9 tonnes per capita needed for the Paris agreement target.
Still lower than average CO2 footprint in the U.S. or U.K.
Policymakers need to address affluent household consumption for sustainability.

Implications for Environmental Justice

Sustainability efforts often focus on global climate change.
Local issues like water scarcity and air pollution are more pressing.
Luxury consumption affects marginalised communities disproportionately.
Affluent sections can afford measures like air purifiers and AC cars.
Multi-footprint analysis is crucial for environmental justice.
Efforts should ensure equitable sustainability for all communities.

Sustainable consumption policies: These policies aim to encourage consumers to make environmentally friendly choices, such as through product labeling, subsidies for sustainable products, or bans on harmful materials.
Green taxation: This approach taxes goods and services with a higher environmental impact, making sustainable options more attractive to consumers.
Consumption inequality: The significant difference in consumption levels between rich and poor households has a major impact on the environment, with affluent consumers often having a much larger footprint.
Affluent consumerism: This refers to the tendency of wealthy individuals to consume more goods and services, often beyond basic needs, leading to increased environmental pressures.
Luxury good consumption patterns: Understanding how luxury goods are produced and consumed helps us track their environmental impact and find ways to make them more sustainable.
Life cycle assessment (LCA) of products: LCA is a method that assesses the environmental impact of a product throughout its entire lifespan, from resource extraction to disposal.
Water scarcity and resource management: As water becomes a scarcer resource, managing consumption and developing sustainable practices are crucial for both households and industries.
