Leaders from the global shipping sector agreed on Friday to cut greenhouse gas (GHG) emissions to net zero “by or around 2050,” despite objections from China and other countries that favored a softer aim. The 175 member states struck an agreement during a five-day summit at the International Maritime Organization (IMO), the United Nations’ global shipping regulator, in London.
According to the IMO, maritime nations have developed a new plan aimed at peaking GHG emissions from international shipping as soon as practicable and achieving net-zero GHG emissions by or around 2050. The timeframe provides for adaptability to diverse national contexts.
While some saw the agreement as unsatisfactory, Vanuatu’s climate change minister voiced confidence, arguing that it provides a chance to reduce global warming to 1.5 degrees Celsius. The maritime industry had established a goal of lowering emissions by at least 50% between 2008 and 2050. The majority of cargo ships use harmful diesel fuel.
Pacific island nations advocated for more aggressive targets, including a 50% decrease by 2030 and a 96% reduction by 2040. These requests were supported by wealthy countries, especially the United States. However, because to objections from China, Brazil, Saudi Arabia, and others, “indicative checkpoints” were included instead of firm targets to reduce annual GHG emissions by at least 20%, striving for 30%, by 2030, and by at least 70%, reaching for 80%, by 2040, compared to 2008 levels.
According to critics, the accord falls short of what is required to successfully combat climate change. They believe the targets should have been more aggressive in order to match with the goal of keeping global warming to 1.5 degrees Celsius. The worldwide shipping business emits more than the whole aviation industry, which seeks to reach net-zero emissions by 2050, despite accounting for approximately 3% of global GHG emissions and transporting up to 90% of trade commodities.
According to the International Council on Clean Transportation (ICCT), the new targets are incompatible with the Paris Agreement’s goal of limiting global temperature rise to 1.5 degrees Celsius by 2100. Experts estimate that the shipping industry must reduce emissions by 45% by 2030 and achieve net-zero emissions by 2050 in order to meet the 1.5 degree Celsius objective.
Despite opposition from some parties, efforts to implement an emissions charge to support climate action have been unsuccessful. The emphasis is now on implementing appropriate incentives to meet the agreed-upon targets. Climate activists continue to advocate for a levy that would result in zero emissions by 2050.
