Today, refrigeration and HVAC accounts for 17% of the global electric consumption.
According to IIR estimations the total number of refrigeration, air-conditioning and heat pump systems in operation worldwide is roughly 3 billion. Global annual sales of such equipment amount to roughly 300 billion USD. Almost 12 million people are employed worldwide in the refrigeration sector which consumes about 17% of the overall electricity used worldwide.
Today, refrigeration and HVAC accounts for 8% of the global greenhouse gas.
The global demand for cooling will significantly increase in the next decades due to growing population, urbanization and cold chains, in particular in emerging economies. From now to 2030, HFCs emissions are forecast to more than double even with the positive impact of the Kigagi Amendment.
According to the Food and Agriculture Organization of the United Nations (FAO), 30 to 40% of food produced for human consumption is lost before it can even make it to market in the developing world, namely due to spoilage (37% at consumer level & 63% at production and distribution level). Most spoilage is due to the cold chain. This wastage results in horrendous costs reaching $696Bn:
In fact the planet produces today enough to feed 2/3 more people than it already does.
Such level of inefficiency has serious economic, social and environmental consequences. The carbon footprint alone of food produced and not eaten is estimated to be 3.3 Gtonnes of CO2 equivalent – in other words, food loss and waste would rank as the third top GHG emitter after USA and China if it were a country
Today, 50% of the global population is living in cities. By 2050, we estimate this number to grow to 70% and population by 35%. That means people are living further away from their food sources.
Accordingly, it seems very important to stop wasting food and find a way, safe and respectful for the environment, to bring all the goods from the producers to the consumers; and so be more responsible to ensure the future of the next generations.
