Paris Agreement: What About Ocean Pollution?

The Paris Agreement is an international accord that was adopted by nearly every nation in 2015 to address climate change and its negative impacts. The agreement aims to reduce global greenhouse gas emissions to limit the global temperature increase in this century to 2 degrees Celsius above pre-industrial levels, while pursuing efforts to limit the increase to 1.5 degrees. While the agreement does not specifically mention ocean pollution, it does address the impacts of climate change on marine ecosystems and the benefits of the agreement for ocean life. Implementing the agreement could protect millions of metric tons in the annual worldwide catch of top revenue-generating fish species, as well as billions of dollars annually in fishers' revenues, seafood workers' income, and household seafood expenditure.

The Paris Agreement's goal of reducing greenhouse gas emissions

The Paris Agreement is a landmark international accord adopted by nearly every nation in 2015 to address climate change and its negative impacts. The agreement's primary goal is to substantially reduce global greenhouse gas emissions and limit the global temperature increase in this century to well below 2°C above pre-industrial levels, ideally limiting the increase to 1.5°C.

To achieve this goal, the agreement includes commitments from all major emitting countries to cut their climate pollution and progressively strengthen these commitments over time. The pact recognises that reducing greenhouse gas emissions is a collective responsibility and provides a framework for developed nations to assist developing nations in their climate mitigation and adaptation efforts. It also establishes a mechanism for transparent monitoring, reporting, and ratcheting up of countries' individual and collective climate goals.

The Paris Agreement could not take effect until at least 55 nations, representing at least 55% of global emissions, had formally joined. This threshold was achieved on October 5, 2016, and the agreement entered into force on November 4, 2016. As of 2025, all 197 countries of the United Nations have endorsed the Paris Agreement, with 195 providing formal approval.

While the agreement has been lauded by world leaders, it has also faced criticism for not being strict enough. Pledges made under the agreement may be insufficient to reach the set temperature goals. Additionally, there is no mechanism to force countries to set specific emissions targets, although each target should exceed previous ones. Despite these challenges, the Paris Agreement has been successfully used in climate litigation to force countries and oil companies to strengthen their climate actions.

The agreement's focus on reducing greenhouse gas emissions is crucial because climate change is already impacting marine social-ecological systems. Scientific projections indicate that if temperatures rise above 2°C, biodiversity and ecosystem services will come under increasing stress. Warming, combined with ocean acidification and deoxygenation, can alter the primary productivity, growth, and distribution of fish populations, affecting the economic and social benefits they provide. By reducing greenhouse gas emissions, the Paris Agreement aims to mitigate these negative effects, protect marine life, and benefit the economies of maritime countries, especially developing nations.

How the agreement could protect marine ecosystems

The Paris Agreement is a landmark international accord that was adopted by nearly every nation in 2015 to address climate change and its negative impacts. While the agreement does not specifically mention "ocean pollution", it does aim to reduce greenhouse gas emissions and limit the global temperature increase, which has positive implications for protecting marine ecosystems.

Marine social-ecological systems are already being affected by climate change, with fish species shifting their distributions and local fish stocks declining. Scientific projections suggest that if temperatures are not held below 2°C above pre-industrial levels, there will be increased stress on biodiversity and ecosystem services. Warming, ocean acidification, and deoxygenation can change the primary productivity, growth, and distribution of fish populations, impacting the potential yield of exploited marine species.

By aiming to keep the global temperature increase "well below 2°C" and "pursuing efforts to limit warming to 1.5°C", the Paris Agreement could help mitigate these negative effects on marine ecosystems. This includes protecting millions of metric tons of annual worldwide catch of top revenue-generating fish species, as well as billions of dollars annually in fishers' revenues, seafood workers' income, and household seafood expenditure.

Additionally, the agreement provides a pathway for developed nations to assist developing nations in their climate mitigation and adaptation efforts. This is particularly important for maritime countries, as the Paris Agreement could protect territorial waters and maintain habitat suitability for tropical species, mitigating potential decreases in biomass and catch.

Overall, the Paris Agreement's focus on reducing greenhouse gas emissions and limiting temperature increase has the potential to protect marine ecosystems, fish populations, and the economies that depend on them.

The agreement's potential to benefit maritime countries

The Paris Agreement is an international accord that was adopted by nearly every nation in 2015 to address climate change and its negative impacts. The agreement aims to substantially reduce global greenhouse gas emissions to limit the global temperature increase in this century to well below 2°C above pre-industrial levels, pursuing efforts to limit the increase to 1.5°C.

The Paris Agreement has the potential to benefit maritime countries in several ways. Firstly, it aims to mitigate the impacts of climate change on marine ecosystems, which are already being affected by warming, ocean acidification, and deoxygenation. By implementing strategies to keep the average temperature increase below 2°C, the agreement can help maintain the habitat suitability for tropical marine species and protect their distributions. This is crucial for the future of ocean ecosystems, as it can prevent the decline of local fish stocks and ensure sustainable fishing practices.

Secondly, the agreement is projected to have positive economic impacts on maritime countries, particularly in the fishing industry. Implementing the agreement could protect millions of metric tons in the annual worldwide catch of top revenue-generating fish species, resulting in billions of dollars in annual revenues for fishers, seafood workers, and related industries. According to studies, achieving the agreement's targets could increase sustainable global fish catches of these species by 7.3% per year or 3.3 million metric tons, with approximately 90% of this increase occurring within the territorial waters of developing maritime countries. This would significantly boost the economies of these nations, providing income and employment opportunities for their populations.

Additionally, the Paris Agreement provides a framework for developed nations to assist developing countries in their climate mitigation and adaptation efforts. This includes knowledge sharing, technology transfer, and financial support to enhance climate resilience and foster low-greenhouse-gas-emissions development. By working together and sharing resources, maritime countries can better address the challenges posed by climate change and protect their unique ecosystems.

Furthermore, the agreement's focus on reducing greenhouse gas emissions and promoting clean energy can have indirect benefits for ocean health. By reducing carbon pollution and transitioning to renewable energy sources, the agreement can contribute to improving ocean water quality, reducing ocean acidification, and mitigating the impacts of climate change on marine life. Maritime countries, in particular, have a stake in this, as they are often vulnerable to the effects of climate change, such as rising sea levels and extreme weather events.

In conclusion, the Paris Agreement has the potential to bring significant benefits to maritime countries. By addressing climate change and its impacts on marine ecosystems, the agreement can help protect fish stocks, support the fishing industry, and boost local economies. Additionally, the framework for international cooperation and assistance provides opportunities for knowledge sharing and financial support to enhance climate resilience and foster sustainable development in maritime nations.

The impact of climate change on marine social-ecological systems

Marine social-ecological systems are already being affected by climate change, with fish species shifting their distributions, resulting in the decline of some local fish stocks. Scientific projections suggest that if temperatures are not held below 2°C above pre-industrial levels, there will be an increase in stress on biodiversity and ecosystem services over the course of the 21st century. Warming, ocean acidification, and deoxygenation, combined with other stressors, could change the primary productivity, growth, and distribution of fish populations. This could result in changes in the potential yield of exploited marine species and the economic and social benefits they provide. For example, the economic benefits of fish populations include billions of dollars annually in fishers' revenues, seafood workers' income, and household seafood expenditures.

To combat these negative effects of climate change, the global community adopted the Paris Agreement in 2015. The agreement aims to implement strategies to keep the average temperature increase "well below 2°C" and “pursue efforts to limit warming to 1.5°C". The Paris Agreement is a landmark international accord that addresses climate change and its negative impacts. The agreement requires countries to make commitments to reduce global greenhouse gas emissions and strengthen these commitments over time.

The Paris Agreement could protect millions of metric tons in the annual worldwide catch of top revenue-generating fish species. This protection would occur primarily within the territorial waters of developing countries, which are projected to see higher fish biomass and catch potential with the achievement of the Agreement. By maintaining suitable habitats for tropical species, the Agreement can mitigate potential decreases in biomass and catch. Additionally, the Agreement provides a pathway for developed nations to assist developing nations in their climate mitigation and adaptation efforts.

Overall, the Paris Agreement is crucial for the future of the world's ocean ecosystems and economies. By addressing climate change and its impacts, the Agreement helps protect marine social-ecological systems and the benefits they provide. However, it is important to note that the effectiveness of the Agreement depends on the collective efforts and commitments of the countries involved.
