When we first heard that Calgary is considered the cleanest city in the world, we were a bit skeptical.
The city is, both geographically and economically, at the centre of the country's oil and gas industry, and Alberta's industrial facilities are responsible for48 per cent of Canada's annual industrial greenhouse gas emissions in 2011. According to the Government of Alberta, Alberta leads the country in the per capita disposal of Municipal Solid Waste at 2134 pounds per person.
But the City of Calgary has made great strides over the years in terms of sanitation and eco-initiatives, which are reflected in our sparking aqua rivers and litter-free streets.
The Too Good To Waste program, initiated in 2007 by the province, outlined ways to decrease the amount of waste sent to landfills. More commitment was given to recycling materials left over from Calgary's housing boom, including wood, asphalt, drywall, shingles and concrete. Calgary has also made a commitment to divert 80 per cent of city waste away from landfills by 2020.
The Green Calgary website offers Calgarians advice on how to compost, pack a litterless lunch and what can go in a recycling bin. Additionally, Calgarians face steep fines for littering from cars and chucking cigarette butts on the ground - up to $1,000.
Calgary's mayor, Naheed Nenshi, announced this week he would seek P3 funding from the federal government to finance a $133-million compost facility.
Calgary has consistently ranked in the top three of Mercer Global Financial and HR Consulting's world's cleanest cities for the past five years. The study is based on five factors: water availability and drinkability, waste removal, quality of sewage systems, air pollution and traffic congestion.
