(Eco Business, 9 Nov 2017) Construction materials, buildings and transport are the main emitters of greenhouse gases at the city level - and their carbon footprint should be lowered, says a report.

Cities should try to slash the planet-warming gases pumped out beyond their own boundaries in the production of the vast quantities of goods and services they consume, researchers said.

Upstream emissions – those generated along the global production chain when cars, clothes or building materials roll out of factories around the world – are broadly on a par with those cities generate directly, said a study by scientists from Germany and the United States published by Nature Scientific Reports this week.

Focused on Mexico City, Berlin, Delhi and New York, it found that energy-intensive construction materials including cement and steel, along with transport, are among the biggest producers of emissions along the supply chain.
