Question

Give some examples of international environmental conventions and treaties.

Short answer

Examples include the Kyoto Protocol, the Paris Agreement, the Convention on Biological Diversity, and the Montreal Protocol.

Step-by-step solution

Understanding the Scope

We need to identify and provide examples of international conventions and treaties that focus on environmental issues. These are formal agreements between countries aiming to address various global environmental challenges.

Example 1 - The Kyoto Protocol

The Kyoto Protocol is an international treaty that extends the 1992 United Nations Framework Convention on Climate Change (UNFCCC) that commits state parties to reduce greenhouse gas emissions, based on the premise that (a) global warming exists and (b) human-made CO2 emissions have caused it.

Example 2 - The Paris Agreement

The Paris Agreement is a landmark environmental 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 and to limit the global temperature increase to 2 degrees Celsius above pre-industrial levels.

Example 3 - The Convention on Biological Diversity (CBD)

The Convention on Biological Diversity (CBD) is an international treaty devised for the conservation of biological diversity, the sustainable use of its components, and the fair and equitable sharing of benefits arising from genetic resources.

Example 4 - The Montreal Protocol

The Montreal Protocol is an international treaty designed to protect the ozone layer by phasing out the production and consumption of numerous substances responsible for ozone depletion. It was agreed on in 1987 and has been successful in reducing global production of ozone-depleting substances.

Key concepts

Kyoto Protocol

The Kyoto Protocol is a significant international treaty aimed at combating climate change. Established under the United Nations Framework Convention on Climate Change (UNFCCC), it was adopted in 1997 and came into force in 2005. The treaty commits industrialized countries to reduce their greenhouse gas emissions, based on the understanding that these nations are primarily responsible for the high levels of emissions currently affecting our planet. The main gases targeted include carbon dioxide ( ext{CO}_2), methane ( ext{CH}_4), and nitrous oxide ( ext{N}_2 ext{O}).

Some key features of the Kyoto Protocol include:

• Binding emission reduction targets for developed countries.
• Emission trading systems enabling countries to sell excess credits.
• Clean Development Mechanism (CDM) that allows emission-reduction projects in developing countries.

While the Kyoto Protocol was a groundbreaking step, it faced criticism for not imposing binding targets on developing countries and had uneven participation, particularly with the United States not ratifying the treaty.

Paris Agreement

The Paris Agreement is a pivotal accord within the global environmental landscape, adopted by 196 countries during the UN Climate Change Conference in Paris in 2015. This universal agreement aims to address the urgent threat of climate change by limiting global warming to well below 2 degrees Celsius above pre-industrial levels, with efforts to limit the temperature increase even further to 1.5 degrees Celsius.

Key aspects of the Paris Agreement include:

• Nationally Determined Contributions (NDCs), allowing countries to set their own emissions reduction targets.
• Aiming for carbon neutrality by the second half of the 21st century.
• Regular assessment and communication of climate action progress.

The Paris Agreement is unique as it represents a bottom-up approach compared to previous treaties, encouraging participation from all countries, regardless of their economic status or existing emissions levels. This treaty acknowledges the necessity of supporting developing countries both financially and technologically to adapt to climate impacts.

Convention on Biological Diversity

The Convention on Biological Diversity (CBD) is a pivotal treaty adopted in 1992 during the Earth Summit in Rio de Janeiro, Brazil. It aims to promote sustainable development by focusing on three main objectives: the conservation of biological diversity, the sustainable use of its components, and the fair and equitable sharing of benefits derived from genetic resources.

Highlights of the CBD include:

• Promoting the establishment of protected areas to conserve biodiversity.
• Encouraging research and coordination among participating countries.
• Fostering access to genetic resources and associated traditional knowledge.

The convention considers biodiversity as not only a matter of preserving ecosystems but as a broader issue related to cultural values, economic development, and the balance of ecosystems services essential for human welfare. By addressing such wide-ranging issues, the CBD plays a crucial role in promoting environmental sustainability.

Montreal Protocol

The Montreal Protocol stands out as one of the most successful international environmental agreements to date. Agreed upon in 1987 and enforced in 1989, it focuses on phasing out the production and use of substances that deplete the ozone layer. These substances include chlorofluorocarbons (CFCs), halons, and other related chemicals.

Some significant achievements of the Montreal Protocol include:

• The complete phase-out of major ozone-depleting chemicals.
• Significant recovery of the ozone layer, with expectations of full healing by the middle of the 21st century.
• Prevention of millions of skin cancer cases and cataracts worldwide.

The Montreal Protocol is internationally hailed for its adaptability and effectiveness, partly because it allows for regular amendments and adjustments as new scientific knowledge and technologies emerge. This treaty exemplifies collaborative international commitment, coming into force with universal ratification by all UN member countries.
