The carbon footprint of cooling is growing at a rate which is at least three times faster than the global average increase of GHG emissions. However, its impact can be minimised by green cooling technologies. They combine maximised energy efficiency with the use of natural refrigerants.
The Green Cooling Technologies Study tracks global market trends of key refrigeration and air conditioning subsectors. The study illustrates the demand and supply side of AC chillers, unitary air-conditioners and mobile air-conditioning and analyses the potential of green technologies in these sectors. It provides an overview of the global value chain for key RAC subsectors and looks closer at how private and public stakeholders as well as the civil society can drive the dynamics towards a wider penetration of green cooling technologies.
The refrigeration and air conditioning sectors are responsible for about 7% of global greenhouse gas (GHG) emissions today, equivalent to 3.7 Gt CO2eq per year (2014) going up to 8.1 Gt CO2eq (2030). Emissions are growing at a rate which is at least three times faster than the global average increase of GHG emissions. Emissions in the RAC sectors originate from the use of high-global-warming-potential (GWP) refrigerants and the energy consumption of RAC systems. By leapfrogging from high-GWP refrigerants to low-GWP natural refrigerants and applying best in class, highly energy efficient appliances, about 40% of the emissions can be avoided globally by 2030 against the business-as-usual (BAU) scenario.
The study provides best practice case studies which showcase the breakthrough of green cooling technologies (e.g. the GreenFreeze refrigerator) and highlights front runners among the public and private sector as well as from the civil society.
