Earth Day 2026: Reassessing the Global Emissions Map

From energy to the military—who is truly responsible for our planet’s emissions?

Every April 22, the world seems invited to pause and reflect on our relationship with the Earth. The land we stand on, the air we breathe, and the water we use every day. This year’s theme, “Our Power, Our Planet,” feels increasingly relevant. The message is simple yet powerful: we have control, and the Earth is a shared responsibility. However, behind that message lies a crucial question: so far, how have we been using that “power”?

Data reveals an increasingly alarming trend. Global greenhouse gas emissions continue to rise, reaching 37.4 billion metric tons of CO₂ equivalent in 2023—the highest level in modern history. According to a report by the World Meteorological Organization (WMO), global CO₂ concentrations surged to +424 ppm in 2024, marking the largest annual increase since 1957.

The global climate report published by NOAA’s National Centers for Environmental Information indicates that 2024 was the hottest year since global records began in 1850, with temperatures 1.46°C above the pre-industrial average (1850–1900). Compared to the 20th-century average, the increase reached 1.29°C. According to the IPCC, emissions must be reduced by 43% from 2019 levels before 2030 to keep global warming below 1.5°C. To understand where change must be directed, we need to examine the sources of the problem, sector by sector, without exception.

Emission Map: Who Does What

Global emissions do not stem from a single source. They are the cumulative result of various interconnected sectors, each bearing its own share of responsibility.

Energy and electricity are the largest contributors, accounting for around 34% of total global emissions. The burning of coal, oil, and gas to generate electricity and heat is a legacy of two centuries of industrialization that we have yet to leave behind. Although renewable energy capacity is growing rapidly, the transition is not fast enough to keep up with rising global energy demand.

Agriculture and land use contribute about 22%. This includes methane emissions from livestock, nitrous oxide from fertilizer use, and CO2 from deforestation and land-use change. The greatest irony in this sector is that forests, which should act as carbon sinks, are instead burned and cleared for new agricultural land, turning them into carbon sources.

Industry and manufacturing contribute around 21%. The production of cement, steel, aluminum, and chemicals requires extremely high temperatures, which still largely depend on fossil fuels. Decarbonizing heavy industry remains one of the most complex technical challenges in the global climate transition.

Transportation accounts for about 16% of global emissions, with aviation and shipping as the most difficult subsectors to control. Electric vehicles are beginning to reshape land transport, but large-scale solutions for air and sea transport are still under development.

Buildings and construction contribute about 6%, mainly from heating, cooling, and lighting systems that still rely on fossil-based electricity. Energy efficiency in buildings offers one of the best cost-benefit solutions available today, yet adoption remains slow in many developing countries.

Each sector has its own story—and each story ends with the same question: are we taking it seriously enough?

A Sector Rarely Mentioned

There is one sector that rarely enters mainstream climate discussions, despite its significant contribution: the military and defense sector. Estimates suggest it accounts for around 5.5% of global emissions—equivalent to more than 2 billion tons of CO₂ equivalent annually.

What makes this issue more critical is not only the scale, but also the lack of transparency. Unlike other sectors, military emissions are not comprehensively reported under international frameworks such as the Kyoto Protocol or the Paris Agreement.

The following facts may help provide a more complete picture.

WHAT IS NEVER INCLUDED IN CLIMATE REPORT TABLES

1. The U.S. military consumes more than 85 million barrels of fuel annually.
2. A single F-35 fighter jet can burn approximately 5,600 liters of fuel per hour.
3. Global military spending reached $2.7 trillion in 2025.
4. Individual actions remain important, but their impact is far smaller than large-scale operational decisions.
5. Armed conflicts not only generate emissions but also destroy carbon sinks.

The impact of military conflicts also extends significantly to environmental aspects. For example, in the case of the conflict in Gaza, carbon emissions over a 60-day period are estimated to have reached 281,000–450,000 metric tons of CO₂ equivalent, equivalent to the annual emissions of a coal-fired power plant. The post-conflict reconstruction process can even add millions of tons of CO2 to emissions. Overall, the global military sector is estimated to account for about 5.5% of global greenhouse gas emissions, although this contribution is often not included in formal reporting such as the Paris Agreement.

“Our Power” and a Bigger Question

There is a fundamental imbalance in how climate responsibility is distributed. Developing countries, despite contributing less historically, face greater pressure to transition quickly. Meanwhile, major emitters often move at a slower pace.

The theme “Our Power, Our Planet” becomes meaningful when interpreted as a call to use our power effectively: technological innovation, regulatory strength, and collective action to ensure transparency across all sectors.

Ultimately, the Earth recognizes no exceptions. Every ton of carbon emitted is treated the same by the atmosphere.

The question is no longer “who is responsible,” but “who is willing to act faster and more transparently.” The Earth cannot wait, and recovery will not happen on its own, it depends on the decisions we make today.
