The United Nations Development Programme (UNDP) releasing a climate dictionary is a valuable resource for enhancing understanding and communication about climate-related issues. Climate change and sustainable development are critical global challenges, and having a standardized set of definitions for key terms can promote clarity and effective dialogue among researchers, policymakers, and the general public. A few terms:

• The "blue economy" concept seeks to promote economic development, social inclusion, and the preservation or improvement of livelihoods while at the same time ensuring environmental sustainability of the oceans and coastal areas.
• Carbon removal is the process of removing greenhouse gas emissions from the atmosphere, through natural solutions such as reforestation and soil management or technological solutions like direct air capture and enhanced mineralization.
• Carbon footprint is a measure of the greenhouse gas emissions released into the atmosphere by a particular person, organization, product, or activity. A bigger carbon footprint means more emissions of carbon dioxide and methane, and therefore a bigger contribution to the climate crisis.
• Carbon markets are trading schemes that create financial incentives for activities that reduce or remove greenhouse gas emissions. In these schemes, emissions are quantified into carbon credits that can be bought and sold.
• Circular economy refers to models of production and consumption that minimize waste and reduce pollution, promote sustainable uses of natural resources, and help regenerate nature.
