Climate Justice and Study Abroad

Insights and Research

This page provides key insights and research on the environmental and social impacts of study abroad and international travel, shedding light on the complexities of carbon emissions, offsets, and the need for a more just approach to climate responsibility. It also offers additional context to help understand the role and relevance of Carbon Onsetting within this framework.

​​

1. Study Abroad and International Travel’s Environmental Impact

✈️ Carbon Emissions from Air Travel

  • A single round-trip flight from Washington, D.C. to Barcelona emits approximately 2.3 metric tons of CO₂ per passenger—equivalent to driving a gasoline-powered car for over 5,000 miles.

  • There are multiple carbon calculators available to measure flight emissions, each using slightly different methodologies. Here are a few reliable tools:

  • Variations in reported emissions for the same flight (departure city to arrival city)? These differences occur because there are multiple ways to measure impact, using different assumptions about aircraft type, passenger load, and fuel efficiency. See this Guardian article for more information. (See Section 3 below)

  • Additionally, be mindful of the date of data sources—a recent study of 2019 data found that emissions were underreported by approximately 33%.

  • While flights are the largest single contributor to a study abroad student’s carbon footprint, they are not the only source of emissions while abroad.

Aviation’s Larger Climate Impact​

  • The aviation sector is responsible for 2-3% of global CO₂ emissions, but its total climate impact is even higher when factoring in non-CO₂ effects such as nitrogen oxides, contrails, and high-altitude emissions.

  • While this percentage is lower than ground transportation, the key difference is who is emitting. Air travel is highly concentrated among wealthier populations, and 1% of the world's population is responsible for 50% of aviation emissions.

  • Given this extreme inequality in emissions, those who travel frequently—including study abroad students—have a greater responsibility to minimize their impact.

Study Abroad, Frequent Flying and Tourism​

  • Multiple flights per student significantly increase their carbon footprint, especially when programs involve stopovers and connecting flights.Takeoff and landing consume the most fuel, meaning that flights with multiple layovers result in higher emissions than direct routes.

  • The culture of study abroad often encourages extensive travel beyond the host country. Some students visit 5 or more countries in one semester, greatly compounding their emissions.

  • Encouraging Planetary Citizenship

    • While we encourage students to become global citizens, we must also emphasize the importance of being planetary citizens—recognizing the environmental impact of their mobility and making more sustainable choices.

    • We applaud students who take advantage of their youth and sense of adventure, as study abroad provides unique opportunities for personal growth, cross-cultural exchange, and transformative experiences. We also recognize the valuable lessons learned by those who engage with the world in socially and culturally responsible ways.

    • However, adventure and exploration must be balanced with responsibility and humility. The ability to travel freely is a privilege, and as travelers, we have a duty to minimize our impact, respect the communities we visit, and contribute to a more sustainable global exchange.

🏙️ Beyond International Flights: The Broader Environmental Impact of Study Abroad

 

While international flights usually account for the largest share of emissions,study abroad programs contribute to environmental impact in other significant ways. Key factors include:

  • Local Travel & Mobility: The Hidden Carbon Cost

    • Many programs involve domestic travel within the host country, adding emissions from buses, trains, and short-haul flights.

    • Personal travel is a major contributor—many students take advantage of cheap flights and open borders, particularly in regions like Europe, where frequent weekend trips by air or rail are common.

    • Some programs promote themselves based on travel access, emphasizing their location’s proximity to multiple destinations. Even study abroad advisors sometimes recommend programs that allow students to travel extensively during their stay.

    • A quick web search reveals faculty and advisors encouraging students to "see as much as they can" while abroad, further reinforcing the culture of high-mobility study abroad experiences.

    • Be wary of study abroad programs referred to as “trips.”

  • Sustainability Gaps: Leaving Eco-Conscious Practices Behind

    • Students may use resources less sustainably while abroad, particularly if they are unfamiliar with local waste management, recycling, or conservation efforts.

    • They may increase their use of single-use plastics and imported goods, either due to convenience or lack of awareness.

    • Some students may think:
      "I don’t fully understand how to reduce consumption or recycle responsibly here, so I’ll just focus on minimizing my impact once I’m back home."

    • Fragile ecosystems and regions with limited infrastructure face greater environmental strain from international visitors. Study abroad participants should be mindful of their impact in these settings.

The cultural expectation of extensive travel and a potential lack of sustainable habits abroad contribute significantly to study abroad’s overall environmental footprint. While these impacts are difficult to quantify, as they largely depend on individual choices, they are still critical to acknowledge.

​​

The goal at this moment is not precise measurement but rather an awareness that study abroad often leads to a higher carbon footprint, regardless of the international flight. The combination of frequent travel and possible disconnection from eco-conscious practices suggests that, in most cases, the true environmental impact of study abroad is underestimated.

Does Study Abroad Always Increase Carbon Emissions?

 

Not necessarily. Beyond international travel, the total impact depends on the student’s lifestyle abroad compared to their home institution.

  • If a student moves from a high-emitting campus to a low-emission environment, their overall carbon footprint could decrease.

    • Example: A student leaving a large, energy-intensive U.S. campus for a low-impact, rural-based program may have lower energy use, eat more locally sourced food, and engage in fewer high-carbon activities outside of the international flight.

​​

  • If a student moves from a low-emission campus to a high-emission environment, their overall footprint may increase significantly.

    • Example: A student moving from a small, walkable college campus to an urban center like Barcelona will likely use more energy, rely on transportation more frequently, and consume more imported goods.

 

  • Institutional Initiatives: Universities, program providers, and study abroad offices are increasingly recognizing the significant carbon footprint associated with international education and are implementing measures to mitigate their environmental impact. While these efforts may not fully achieve carbon neutrality, they can help balance the overall footprint when compared to students' emissions while on campus.

    • Carbon Offset Programs: Many universities are introducing programs allowing students to offset a portion of the carbon emissions from their study abroad flights by purchasing carbon offsets.

    • Collaborative Efforts: Some colleges encourage students to purchase carbon offsets for their study abroad flights and match these contributions up to a certain amount annually. 

    • Sustainability Commitments: Many Education Abroad departments aim to achieve carbon neutrality by a given year, aligning with their university's broader goal of carbon neutrality.

    • Educational Integration: Many institutions offer study abroad programs that focus on sustainability, allowing students to engage directly with environmental practices and principles in various global contexts.

 

🔍 Key Takeaways:

  • The privilege of international travel comes with responsibility.

  • Direct flights and mindful travel planning can reduce emissions.

  • Balancing adventure with responsibility is key.

  • The international flight often increases a student’s overall carbon footprint, but it doesn’t tell the whole story.

Social Cost of Carbon

2. The Social Impact of Carbon Emissions & the Global South

🌍 Disproportionate Burden on Vulnerable Communities

  • Economic Inequality and Climate Vulnerability: Climate change exacerbates existing inequalities, disproportionately affecting low-income communities that have contributed the least to global emissions. These populations often lack the resources to adapt and respond to climate impacts, leading to heightened vulnerabilities.

  • Health Impacts: Climate change leads to rising global temperatures, extreme weather events, and health issues such as shifting disease patterns—all of which disproportionately affect marginalized communities.

  • Food and Water Security: Climate change disrupts food production and access to clean water, driving up hunger and increasing resource scarcity. When climate disasters damage farmland and threaten coastal fisheries, food production suffers, leading to higher food prices and hunger.

  • Forced Migration: Climate-related events force millions to migrate from their homes or regions, creating highly vulnerable populations. Migration can be temporary or permanent, internal or international, and may be voluntary or involuntary, resulting from slow-onset or acute events.

 

🔥 Global South: Bearing the Brunt of Emissions

  • Historical Emission Disparities: Although emissions from the Global South have increased in recent decades, the Global North is responsible for approximately 92% of excess historical carbon emissions—the emissions that have driven climate change since the Industrial Revolution. Despite having significantly lower per capita emissions today, the Global South is often expected to shoulder the burden of climate mitigation efforts, such as reforestation, conservation, and carbon sequestration, while facing the most severe consequences of climate change.

  • Climate Colonialism refers to how Global North countries leverage their economic and political power to impose environmental policies or extract resources from Global South nations, often under the guise of combating climate change. This dynamic perpetuates historical patterns of exploitation and deepens global inequalities.

  • Climate Apartheid highlights the divide between affluent and impoverished communities in their capacity to withstand climate-related disasters. Wealthier populations can afford protective measures, while marginalized groups face the brunt of environmental hazards.

  • Solastalgia: The Emotional Toll of Climate Change. As climate change disrupts ecosystems, displaces communities, and alters landscapes, many people experience solastalgia—a profound sense of loss and distress caused by environmental degradation. This psychological impact is especially acute in Indigenous and frontline communities whose cultural identities are deeply tied to their lands. As biodiversity declines and territories are lost, solastalgia fuels cultural erosion and deepens the injustices of climate change.

 

⚖️The Social Cost of Carbon

 

The social cost of carbon (SCC) quantifies the economic damages associated with emitting one additional ton of carbon dioxide into the atmosphere. This metric encompasses various climate change-induced impacts, including reduced agricultural productivity, human health deterioration, property damage from increased flood risk, and changes in energy system costs. 

  • These figures are instrumental in shaping policies and regulations aimed at reducing carbon emissions by assigning a tangible economic value to the long-term damages caused by climate change.

 

Despite estimates placing the SCC between $51 and $185 per ton, carbon offsets in the voluntary market are often significantly undervalued. Prices range from as low as $5 to $100 per ton, failing to reflect the true economic and social damages caused by emissions.

  • This discrepancy highlights a fundamental issue: many carbon offsets are undervalued and fail to reflect the true economic and social damages caused by emissions.

  • In contrast, the Carbon Onset plan advocates for a fair trade value of approximately $20 per ton—a price designed not only to account for carbon sequestration but also to ensure meaningful investment in community-led restoration, ecological regeneration, and social equity in the regions most affected by climate change.

  • This pricing disparity also exposes a deeper flaw: the voluntary carbon market, by nature, is driven by supply and demand rather than actual climate needs (see Section 4 below). 

 

🔍 Key Takeaways: 

  • Climate change amplifies existing inequalities, disproportionately impacting vulnerable communities.

  • The Global South bears the burden of climate mitigation despite contributing the least to historical emissions.

  • Climate colonialism and economic disparity fuel environmental injustice.

  • The true cost of carbon is far higher than market prices, exposing fundamental flaws in the voluntary carbon market.

Calculating Carbon

3. How Carbon Emissions Are Calculated for International Travel and How to Do Your Own calculations

 

​This section provides a breakdown of flight emissions and offers a step-by-step guide for institutions that want to conduct a detailed study of their study abroad carbon impact.

📊 Carbon Footprint of Common Flights (per passenger, round-trip)

Popular Routes Study Abroad_edited.png

Estimates calculated for economy seating using the ICAO Carbon Emissions Calculator.

​​

🔢 Several factors determine carbon emissions for flights, including:

​​

  • Fuel consumption & distance traveled – The longer the flight, the more fuel burned.

  • Aircraft type & efficiency – Newer models may be more fuel-efficient than older ones.

  • Passenger load – A full flight distributes emissions across more people, lowering per-passenger impact.

  • Seating class – First and business-class seats emit more CO₂ per passenger due to increased space and weight allocation.

  • Layovers & connecting flights – Takeoff and landing consume the most fuel, making non-direct flights more emissions-intensive.

    • Example: A direct flight from New York to Barcelona emits less CO₂ than a flight that connects through Heathrow. To access accurate CO₂ emissions you should add the CO₂ emission of each individual flight

 

🌍✈️Conducting a Detailed Carbon Calculation for Your Institution

 

We understand that precisely calculating institutional emissions is complex, but for those looking for a more accurate assessment, here are key steps to develop an institution-specific carbon footprint.

Steps for a Detailed Study of Your Institution’s Carbon Footprint

  1. Identify All Participants in International Travel

    • Include students, faculty, and staff participating in study abroad, research trips, conferences, and other institutionally sponsored travel.

  2. Categorize Travel Distances by Environmental Impact

    • Divide travel distances into categories for clearer calculations. Ideally, you would create five categories (short, medium-short, medium, medium-long, long), but three categories (short-haul, medium-haul, and long-haul) also work.

    • Example of 5 Distance Categories:

      • Group 1: Short (0 to 2,000 miles)

      • Group 2: Medium-Short (2,000 to 4,000 miles)

      • Group 3: Medium (4,000 to 6,000 miles)

      • Group 4: Medium-Long (6,000 to 8,000 miles)

      • Group 5: Long (8,000+ miles)

  3. Use Carbon Emission Calculators

    • Determine the average metric tons of carbon emitted for each distance category using reliable carbon emission calculators.

  4. Divide Programs by Expected Additional Travel and Impact

    • Classify programs based on their anticipated environmental impact compared to the impact at the home campus:

      • Group A: Very Low – Likely to have much less impact than at the home campus.

      • Group B: Low – Likely to have less impact than at the home campus.

      • Group C: Moderate – Likely to have a similar impact to the home campus.

      • Group D: High – Likely to have a higher impact than the home campus.

      • Group E: Very High – Likely to have a much higher impact than the home campus.

  5. Determine Net Additions or Reductions to Carbon Emissions

    • Calculate the average net additions or reductions to carbon emissions for each program category by comparing them to average emissions at the home campus.

    • A detailed analysis could include factors like student commuting habits, on-campus travel, energy consumption, and resource use, but this level of precision can be time-consuming and complex.

    • Instead, it may be more practical to use broad estimates based on general trends in campus emissions, focusing on major differences between program types rather than exact calculations.

      • Example: You may decide to equate “very low” impact to at an average of  -2.0 metric ton per student and a net “very high” impact at +2.0 metric tons. 

  6. Classify Travel Destinations and Programs

    • Classify each travel destination or program according to both distance traveled and the expected additional impact or reduction.

  7. Estimate Emissions Per Participant

    • Place each participant into one distance group and one impact group, and use this classification to estimate their carbon emissions.

  8. Calculate the Total Carbon Emissions for the Institution

    • Step 1: Calculate the emissions from all international travel.

    • Step 2: Add or subtract additional travel impact or potential reductions compared to the home campus baseline.

🌍 Final Thoughts on Calculating Study Abroad Carbon Emissions

 

By following this process, institutions can move beyond generalized estimates and develop a more accurate and transparent understanding of their study abroad carbon footprint. While precision is valuable, it is not the end goal—the objective is to increase awareness, identify reduction opportunities, and encourage responsible travel choices.

For institutions where a detailed study feels too complex, broad estimates can still provide valuable insights for sustainability efforts and Carbon Onsetting investments.

🔍 Key Takeaways:

  • International travel has a significant carbon footprint.

  • Multiple factors influence emissions, including flight choices and program structure.

  • Study abroad emissions vary—some students may have a lower footprint abroad than on campus.

  • Institutions can assess their impact through tailored calculations.

  • With privilege comes the responsibility to minimize environmental harm.

Voluntary Carbon Market

4. The Complexity of Carbon Credits & Carbon Offsetting

 

💰 The Voluntary Carbon Market & Pricing Variability

 

The Voluntary Carbon Market (VCM) allows companies, organizations, governments, and individuals to purchase carbon credits to offset their greenhouse gas emissions outside of regulatory requirements. These credits represent the removal or reduction of one metric ton of CO₂ or its equivalent in other greenhouse gases.

However, the VCM is highly variable and complex, presenting challenges for buyers and policymakers to navigate. Several factors contribute to this:

  • Wide range of prices: Carbon credits range from $5 to $100 per metric ton, depending on project type, quality, and verification standards.

  • Lack of regulation: With no universal oversight or mandatory standards, organizations are free to choose offsets based on cost rather than effectiveness, leaving many critical restoration efforts underfunded (For example, without clear guidelines, buyers often assume all carbon credits are equal and simply opt for the cheapest option—even if it lacks long-term impact or proper verification).

  • Uncertain impact & permanence: Many low-cost offsets, such as tree-planting projects, lack long-term effectiveness and fail to account for deforestation risks.

  • Market-driven fluctuations: The price of carbon credits depends on supply and demand, rather than the true cost of climate damage or the need for high-quality restoration work.

 

➡️ The Carbon Onset plan provides an alternative, ensuring carbon investments align with environmental justice principles rather than market fluctuations.

📉 The Market’s Failure to Account for True Environmental Costs

 

In market economics, carbon emissions are considered an externality—meaning that polluters do not pay the true cost of their impact on society. Instead, the environmental and social consequences (such as air pollution, health issues, and climate disasters) are absorbed by the public and future generations rather than those responsible for the emissions.

 

🔍 What this means:

  • Offsets often compensate rather than prevent emissions, failing to address the root causes of environmental harm.

  • Many businesses rely on offsets instead of reducing their emissions, using them as a way to maintain unsustainable practices.

  • Without policies that internalize these costs, polluters have little financial incentive to change their behavior—shifting the burden onto vulnerable communities and ecosystems.

 

➡️ Onsets are a tool to change our behavior. They can work independently of offsets or in harmony with those that are properly regulated and accountable.

📉 The Reality of Carbon Offsets: Varied Success & Misuse

 

Not all offsets are created equal—some play a meaningful role in carbon reduction, while others are misused or fail to deliver real benefits.

 

✔️ The potential of high-quality offsets:

 

The risks & challenges:

  • Greenwashing concerns: Some institutions mislead consumers by branding themselves as sustainable while making minimal or ineffective climate investments.

  • Offsets cannot replace emission reductions: They should complement, not justify, high-carbon activities.

  • Behavioral & systemic change is required: The climate crisis cannot be solved through offsets alone—structural shifts in consumption, policies, and accountability are needed.

 

➡️ Offsets, when done effectively and ethically, play a role in a holistic climate strategy. They should never be an excuse for inaction.

📜 Certification and Verification: Who Ensures the Impact?

 

Certification and verification are meant to ensure credibility, but not all systems are equally reliable:

 

✔️ The role of certification:

  • High-quality certifications ensure that carbon credits deliver real, measurable climate benefits and help buyers make trustworthy investments.

 

Challenges with certification models:

  • Exposed for overstating the effectiveness of their projects, leading to false claims of carbon neutrality.

  • Certification is expensive, making it inaccessible to small-scale, community-led initiatives that still provide high-impact restoration solutions.

 

➡️ Not all impactful projects fit traditional certification models. Small-scale local and community-led initiatives may lack access to expensive certifications but still provide high-impact, regenerative solutions that directly benefit ecosystems and local people.

📜 How Pachaysana Verifies and Certifies Carbon Onsetting

 

Unlike traditional carbon offset markets, where third-party certifications are often required to validate impact, the Carbon Onset model prioritizes transparency, community participation, and direct verification.

📋 A Different Approach to Verification

 

Instead of relying on expensive, often inaccessible certification bodies, we use a community-driven verification system that ensures:

​​

  • Direct tracking and reporting – Every eco-action (specific, community-led restoration and conservation activities such as seed collection, reforestation, or soil regeneration) is monitored and documented with photos, progress reports, and testimonies from those directly involved

    • This way, those who purchase onsets can see the real-life impact of their investment, with tangible proof of progress.

  • On-the-ground impact assessment – Local partners and community leaders play a key role in verifying that funds are used effectively and fairly for ecosystem restoration and climate resilience. 

    • This way, the people most affected by climate change ensure that they are the primary financial beneficiaries of your investment.

  • International students, faculty, and visitors verify the work firsthand – Unlike traditional offsets, our programs involve long-term engagement, where study abroad students, interns, volunteers, and faculty members actively participate in restoration efforts for weeks at a time. 

    • This way, investors can have their own people witness and verify the work being done on the ground, reinforcing trust and accountability.

  • Full transparency through direct access – Visitors have full access to the projects, ensuring that communities cannot greenwash their actions. 

    • This way, any investor can visit the project at any time, guaranteeing that the work is authentic, sustainable, and continuously monitored.

  • Regenerative practices over market labels – Rather than fitting into an outsider-imposed certification framework, our work is built around deep-rooted environmental and social responsibility.

    • This way, investments go beyond box-checking and contribute to long-term ecological and community well-being.

​​​

🌱 An Analogy: Organic Food in a College Cafeteria

 

Just as institutions can verify organic food sourcing through direct relationships and transparency rather than relying solely on third-party certifications, our approach to carbon onsetting ensures accountability through community engagement, long-term participation, and open access to projects—demonstrating real impact without the need for external market-driven labels.

  • If a college cafeteria wants to prove they serve organic food, they typically buy from a certified organic supplier—ensuring credibility but often at a higher cost.

  • However, what if the cafeteria buys from a small local farm that follows organic practices but cannot afford certification fees? Or what if the school grows its own produce through a campus farm initiative?

  • In these cases, the cafeteria might verify its organic sourcing through direct relationships, transparent documentation, and farm visits—demonstrating true organic commitment without an external label.

Similarly, our verification system works directly with local communities, conservationists, and restorers, ensuring funding leads to real ecological restoration and climate justice outcomes—even if it doesn’t fit into conventional certification models.

​​​

🔍 Key Takeaways:

  • The voluntary carbon market lacks consistency. 

  • Low-cost offsets can be unreliable and carbon offsets don’t always reduce emissions. 

  • Certifications provide credibility, but they aren’t perfect. 

  • We use direct, community-driven verification with international students and visitors playing a role

  • Carbon onsetting is a more just alternative, investing in community-led restoration, regenerative practices, and environmental justice.

Conclusion: A Call for Smarter, More Just Climate Action

The impact of study abroad and international travel on climate and social justice is undeniable. While market-driven carbon offsets play a role in mitigating emissions, they are not enough to drive systemic change. Institutions should adopt a "carbon onsetting" approach—one that prioritizes long-term environmental restoration, Indigenous land stewardship, social equity, and ethical investment in the regions most affected by climate change.

By shifting from passive compensation to active restoration, Carbon Onsetting ensures that climate action is not just about balancing emissions but about creating long-term resilience for the communities most affected by climate change.

🔍 Key Takeaways:


Beyond Traditional Offsets: Carbon Onsetting complements existing carbon offset strategies by embedding active restoration and community investment into study abroad commitments.
✔ Community-First Investment: Supporting local conservation efforts and Indigenous-led projects ensures that financial contributions lead to real ecological and social impact.
Fair and Ethical Pricing: Institutions can set a just price for climate action, moving beyond the undervalued voluntary carbon market.
An Active, Transparent Process: Unlike traditional offsets, Onsetting prioritizes long-term engagement, direct verification, and open accountability.
