Negative emissions represent a process removing carbon dioxide (CO₂) from the atmosphere and its permanent storage in natural or artificial reservoirs. In other words, these are negative greenhouse gas emissions that reduce the total amount of CO₂ in the atmosphere, as opposed to regular emissions that increase it.

The importance of negative emissions

– Limiting global warming: According to the Paris Agreement, the goal is to keep the increase in global average temperature well below 2°C above pre-industrial levels and to pursue efforts to limit it to 1.5°C. To achieve this goal, it is necessary not only to reduce emissions, but also to remove CO₂ that has already been released into the atmosphere.

– Compensation of unavoidable emissions: Some sectors, such as aviation or industrial processes, may have difficulty reducing emissions to zero completely. Negative emissions can help offset these unavoidable emissions.

– Reversing climate change: Removing CO₂ from the atmosphere can help mitigate or reverse some of the impacts of climate change and stabilize the climate system.

Technologies enabling negative emissions

Negative emissions can be achieved through a variety of natural and technological solutions. These methods focus on: carbon sequestration – its capture and permanent storage.

Climate models are complex mathematical and computer simulations that scientists use to study the Earth's climate and predict its future changes. These models integrate knowledge from physics, chemistry, biology, and meteorology to represent and simulate the interactions between the various components of the climate system:

– Atmosphere

– Oceans

– By land

– Ice cover

– Biosphere

How climate models work

1. Dividing the Earth into a grid:

– The Earth is divided into a three-dimensional network or grid in the models.

– Each grid point represents a specific location with defined properties (temperature, pressure, humidity, etc.).

– Vertical layers allow you to simulate processes at different atmospheric heights and ocean depths.

2. Application of physical laws:

– The models use systems of differential equations based on fundamental physical principles, such as the laws of conservation of energy, mass, and momentum.

– These equations describe the dynamics of the atmosphere and oceans, including heat transfer, air and water movement, cloud formation, and precipitation.

Plastic waste is one of the most pressing environmental issues of our time. Millions of tons of plastic waste enter the oceans every year, affecting not only marine ecosystems but also the global climate.

---

The impact of plastic waste on the oceans

1. Marine pollution:
   • Physical damage to marine life:
     • Ocean pollution with plastics threatens many marine species. Fish, seabirds, turtles and marine mammals can be to tangle into plastic debris, often leading to injuries or death.
   • Ingestion of plastics:
     • Many sea animals consumes plastic debris , mistaking them for food. This can result in digestive blockage , malnutrition and death.
   • Microplastics:
     • Over time, plastic in the ocean they break into small fragments known as microplastics (particles smaller than 5 mm). These microplastics are consumed by plankton , they enter into food chain and potentially affect humans through seafood consumption.
2. Disruption of ecosystems:
   • Transport of invasive species:
     • Floating plastic objects can act as platforms for invasive organisms , which allows them to spread into new areas and threaten native ecosystems.
   • Changing light and heat patterns:
     • Accumulated plastic on the ocean surface can block the penetration of sunlight , disrupt photosynthesis in phytoplankton and change primary productivity in marine ecosystems.

---

The impact of plastic waste on the climate

1. Greenhouse gas emissions throughout the life cycle of plastics:
   • Plastics production:
     • Most plastics are made from fossil fuels (oil and natural gas). Mining and processing a significant amount of these resources is generated carbon dioxide (CO₂) and other greenhouse gases.
   • Processing and transportation:
     • Energetically demanding processes associated with the production and transportation of plastics contribute to further emissions.
   • Plastic disposal:
     • Incineration of plastic waste releases CO₂ and often produces toxic pollutants .
     • Plastic degradation in landfills under anaerobic conditions can produce methane (CH₄) , a potent greenhouse gas.
2. Plastic degradation in the oceans and greenhouse gas emissions:
   • Photodegradation:
     • Plastics exposed sunlight they can release during their decomposition greenhouse gases such as methane and ethylene.
     • Studies show that polyethylene , one of the most common plastics, releases these gases during degradation, contributing to global warming.
3. Impact on marine ecosystems and the carbon cycle:
   • Reduced photosynthesis by phytoplankton:
     • Phytoplankton plays a crucial role in carbon sequestration , absorbs CO₂ from the atmosphere.
     • Plastic pollution can reduce the phytoplankton population, thereby the ocean's ability to absorb CO₂ will decrease .
   • Carbon release from dead organisms:
     • The death of marine organisms due to plastic pollution can lead to releasing stored carbon back into the ocean and atmosphere.

Plastic waste has a major negative impact on oceans also climate It harms marine life, disrupts ecosystems and contributes to greenhouse gas emissions throughout the entire life cycle. Solving this problem requires global cooperation through efforts to reduce plastic production, improve waste management and foster innovation. Every individual can contribute by making responsible consumption decisions and promoting sustainable practices. Tackling the plastic pollution crisis is essential to protecting marine ecosystems and mitigating climate change for future generations.

Agriculture including animal production is a significant source greenhouse gas (GHG) emissions , which contribute to global climate change. Globally, agriculture accounts for approximately 10 – 12 % of total anthropogenic greenhouse gas emissions. If we take into account emissions from land use changes , such as deforestation for agricultural purposes, this proportion is increasing.

Key greenhouse gases in agriculture

1. Methane (CH4):
   • Animal production is a primary source of methane, mainly through enteric fermentation in ruminants such as cows, sheep and goats.
   • Rice cultivation It produces methane due to anaerobic conditions in flooded fields.
2. Nitrous oxide (N₂O):
   • Releases upon application nitrogen-based fertilizers because soil microbes convert excess nitrogen into N₂O.
   • Manure management and the decomposition of organic material also contribute to N₂O emissions.
3. Carbon dioxide (CO₂):
   • Deforestation and land use change for agriculture, they release large amounts of CO₂ stored in plants and soil.
   • The use of also contributes to CO₂ emissions fossil fuels for the production of agricultural machinery and fertilizers.

Detailed impacts of agriculture and livestock production

1. Animal production

• Enteric fermentation:
  • Ruminants They have microbes in their stomachs that break down cellulose and release methane as a byproduct.
  • This methane is released into the atmosphere belching and flatulence .
  • Livestock production contributes approximately 40 % to global anthropogenic methane emissions.
• Manure management:
  • Manure storage and processing produces methane and N2O, especially in anaerobic conditions , such as lagoons or pits.

2. Crop production

• Rice cultivation:
  • Flooded rice fields they create an anaerobic environment where methanogenic bacteria produce methane.
  • Rice cultivation is responsible for approximately 10 % global methane emissions from agriculture.
• Fertilizer use:
  • Excessive application nitrogen fertilizers releases N₂O through nitrification and denitrification in the soil.
  • Nitrous oxide has global warming potential (GWP) approximately 298 times greater than CO₂ over a 100-year period.

3. Land use change and deforestation

• Agricultural land expansion often leads to deforestation , releasing a significant amount of CO₂.
• Forest loss reduces the ability of ecosystems absorb CO₂ , further increasing concentrations in the atmosphere.

4. Emissions from energy use

• Agricultural machinery and devices rely on fossil fuels, which contribute to CO₂ emissions.
• Production agrochemicals (fertilizers, pesticides) is energy-intensive and dependent on fossil fuels.

Strategies to reduce agricultural emissions

1. Optimization of animal production:
   • Improving animal nutrition (e.g. feed additives, probiotics) to reduce methane production.
   • Livestock farming with lower methane emissions.
2. Effective use of fertilizer:
   • Precision agriculture It allows targeted application of fertilizers, thereby reducing excess nitrogen in the soil.
   • Organic farming and growing legumes for natural nitrogen fixation.
3. Improved manure management:
   • Anaerobic digestion manure for production biogas as a renewable energy source.
   • Composting manure to reduce emissions and create high-quality organic fertilizers.
4. Soil protection and carbon sequestration:
   • Conservation tillage (no-till) retains carbon in the soil.
   • Agroforestry combines agriculture with tree planting, increasing biodiversity and carbon sequestration potential.
5. Reducing food waste:
   • Minimizing losses and waste in the food supply chain reduces production needs and related emissions.
6. Dietary changes:
   • Reducing meat consumption , especially red, can reduce demand for animal production and the associated emissions.
7. Technological innovations:
   • Research and development new technologies such as feed additives or advanced agricultural practices to reduce emissions.

The importance of sustainable agriculture

• Food safety for a growing global population is crucial and must be achieved with minimal impact on the climate.
• Sustainable agriculture balances production efficiency with environmental protection.
• Adaptation to climate change is essential to ensure continuous food production.

Agriculture and animal husbandry They contribute significantly to greenhouse gas emissions by releasing methane, nitrous oxide and carbon dioxide. Adopting sustainable practices , technological innovation and changing consumer behaviour can help mitigate these emissions. Addressing the environmental impact of agriculture is key to meeting global climate goals and ensuring food security for future generations.
