Improving urban weather, climate and air quality

I was sitting in an urban comfort university complex in Montreal, Canada, while drinking coffee from a recycled cup  wrapped by recycled sleeve (Figure 1). I thought, if most of the materials that we use are recycled, there will be more reductions in carbon emissions. This would reduce the impacts of the extremes of climate change such as heatwaves, floods and other air and water related storms. So, I appreciated the business model, which gives attention to recycling.  More than 50% emissions reductions are expected by mid- 21st century. Therefore, there should be continuous recycling as can be seen from Figure 1 where the sleeve is made from 100% recycled material and then near the bottom it redirects the consumer to put it in a recycling trash box so that it will be reused. This continuous reusing reduces the new materials  (e.g., forest products, chemicals, etc) required to make the sleeves and the coffee cups and the environmental benefit cannot be underestimated....
