What international agreements and initiatives are in place to address climate change and combat the greenhouse effect?

The main international agreement to address climate change is the Paris Agreement, adopted in 2015 under the United Nations Framework Convention on Climate Change (UNFCCC). This agreement aims to limit global warming well below 2 degrees Celsius above pre-industrial levels. Other important initiatives include the Kyoto Protocol, which sets binding emissions reduction targets for developed countries, and various regional agreements such as the European Union Emission Trading System.

Long answer

The international community has established several agreements and initiatives to tackle climate change and combat the greenhouse effect. The most significant of these is the Paris Agreement, which was reached in December 2015 at the 21st Conference of Parties (COP21) of the UNFCCC. This agreement sets out a comprehensive framework for global efforts to address climate change.

Under the Paris Agreement, nations commit to limiting global warming well below 2 degrees Celsius above pre-industrial levels and pursuing efforts to keep it below 1.5 degrees Celsius. Each country submits voluntary nationally determined contributions (NDCs) outlining their actions and targets on reducing greenhouse gas emissions.

Another important agreement is the Kyoto Protocol, which was adopted in 1997 and entered into force in 2005. It sets binding emissions reduction targets for developed countries (called Annex I parties), with specific commitments varying between nations. However, it does not include major emitters like the United States and China. The Kyoto Protocol expired at the end of 2020 with its replacement being sought under the Paris Agreement.

Alongside these global agreements, there are numerous regional agreements and initiatives addressing climate change. For example, within Europe, one significant initiative is the European Union Emission Trading System (EU ETS). It is a cap-and-trade system that covers multiple sectors of industry within EU member states and enables trading of emission allowances.

Other notable agreements include:

1. Montreal Protocol: Though primarily focused on protecting ozone layer depletion, it has contributed to climate change mitigation by phasing out the production and consumption of several potent greenhouse gases such as hydrofluorocarbons (HFCs).

2. United Nations Environment Programme (UNEP): UNEP promotes international cooperation on adaptation and mitigation measures, supports countries in developing their climate policies, and facilitates technology transfer.

3. Clean Development Mechanism (CDM): Established by the Kyoto Protocol, CDM allows developed countries to invest in emissions reduction projects in developing nations to gain carbon credits and meet their emission targets.

4. Climate Investment Funds (CIFs): CIFs support climate-resilient development and renewable energy investment in developing countries through concessional finance, grants, and loans.

It is crucial to note that the effectiveness of these agreements and initiatives depends on political will, financial support, technological advancements, and robust implementation at both national and international levels. The global community’s ongoing efforts to combat climate change will require continued cooperation, innovation, and coordination among nations.
