Oceans and seas play a vital role in the context of Sustainable Development Goals (SDGs) as they significantly contribute to the Earth's biosphere's health and the global economy. They are critical to sustaining life on earth, acting as a major source of food and oxygen while also serving as natural carbon sinks that mitigate climate change impacts. SDG 14, "Life Below Water," explicitly acknowledges the importance of conservation and the sustainable use of the world's oceans, seas, and marine resources.
Oceans absorb about 30% of carbon dioxide produced by humans, buffering the impacts of global warming. However, this process has implications such as ocean acidification, negatively impacting marine biodiversity and ecosystems. These impacts, coupled with unsustainable fishing practices and pollution, threaten the health of our oceans and seas. SDG 14 sets targets to prevent and reduce marine pollution of all kinds, sustainably manage and protect marine and coastal ecosystems, and regulate harvesting and end overfishing to restore fish stocks to sustainable levels.
Oceans also support economic wellbeing. Over three billion people depend on marine and coastal biodiversity for their livelihoods. By protecting oceanic ecosystems, the SDGs also support SDG 1, "No Poverty," and SDG 8, "Decent Work and Economic Growth." Furthermore, the oceanic routes are critical for global trade, supporting SDG 9, "Industry, Innovation, and Infrastructure."
Furthermore, by implementing strategies for cleaner and more sustainable use of oceans and seas, it can also contribute to SDG 13, "Climate Action." For instance, developing and implementing new technologies to harness energy from waves and tides can promote renewable energy usage and reduce reliance on fossil fuels, aligning with SDG 7, "Affordable and Clean Energy."
COP26 is the 2021 United Nations annual climate change conference. COP stands for Conference of the Parties. Parties are the signatories of the United Nations Framework Convention on Climate Change (UNFCCC) - a treaty agreed in 1994 which has 197 Parties (196 countries and the EU). The 2021 conference, hosted by the UK, together with our partners Italy, in Glasgow, will be the 26th meeting of the Parties, which is why it's called COP26.

Since the launch of the United Nations (UN) Sustainable Development Goals (SDGs) in 2015, the SDGs have been widely adopted by governments and corporations in an effort to improve their sustainability. There are 17 SDGs, comprising 169 targets, which are measurable against 247 unique indicators. Despite pervasive global pollution from (micro)plastics, there is only one indicator (14.1.1b) under Goal 14, specifically related to reducing impacts from (micro)plastics.
