As a major oil and gas exporter, Iran`s energy sector accounts for about 77% of its total emissions. Despite its fossil fuel empire, the country has developed a renewable energy industry through a series of national plans and funds. The Paris Agreement contains a series of binding measures to monitor, verify and publicly report progress towards a country`s emissions reduction targets. Improving transparency rules applies a common framework to all countries, providing housing and support to nations that are not currently able to strengthen their systems over time. Carbon dioxide, nitrous oxide and methane are gases that accumulate in the atmosphere and prevent radiation from the Earth`s surface to space, creating what is called the greenhouse effect. According to the Intergovernmental Panel on Climate Change (IPCC), the main international panel on this issue, the concentration of these thermal gases has increased significantly since pre-industrial times and has not been observed for at least 800,000 years. Carbon dioxide (the main cause of climate change) has increased by 40 per cent, nitrous oxide by 20 per cent and methane by 150 per cent since 1750, mainly due to the burning of dirty fossil fuels. The IPCC says it is „extremely likely“ that these emissions have been primarily responsible for the rise in global temperatures since the 1950s. Meanwhile, deforestation and forest degradation have also contributed to their fair share of global carbon emissions. In 1992, President George H.W. Bush joined 107 other heads of state at the Rio Earth Summit in Brazil to adopt a series of environmental agreements, including the UNFCCC framework, which is still in force today.
The international treaty aims to prevent dangerous human intervention in the planet`s climate systems in the long term. The pact does not set limits on greenhouse gas emissions from individual countries and does not contain enforcement mechanisms, but establishes a framework for international negotiations on future agreements or protocols to set binding emissions targets. Participating countries meet annually at a Conference of the Parties (COP) to assess their progress and continue discussions on how best to combat climate change. At the 2015 Paris conference, at which the agreement was negotiated, developed countries reaffirmed their commitment to mobilize $100 billion a year to finance climate by 2020 and agreed to continue mobilizing $100 billion a year by 2025.  The commitment refers to the existing plan to allocate $100 billion per year to developing countries for climate change adaptation and climate change mitigation.  The Paris Agreement marks the beginning of a shift towards a low-carbon world – much remains to be done. Implementation of the agreement is essential to achieving the Sustainable Development Goals, as it contains a roadmap to combat climate change to reduce emissions and build resilience to climate change. Despite Trump`s campaign promises, the White House is under intense pressure to stay in the Paris accord. Foreign Secretary Rex Tillerson, Energy Secretary Rick Perry, counselor and first daughter Ivanka Trump and her husband, adviser Jared Kushner, support staying in the agreement, but with some adjustments to the emissions target. Large groups such as oil giant Exxon Mobil Corp. have also warned Trump that he will not relinquish the deal.
