It’s worth arriving at a UN climate summit tooled up with stats: you never know who you might meet on the bus.

Below is a selection of some of the year’s best studies on the green economy, climate finance flows, record temperatures and cooling interest in coal.

They illustrate reasons to be happy (carbon intensity is falling), worried (the oceans are heating up), amazed (half million solar panels were plugged in every day last year) and sad (300 million kids breathe in toxic fumes every year).

9. UNICEF: 300 million children are breathing in toxic air every year, leading to hundreds of thousands of deaths linked to vehicles emissions, waste burning and power plants (Report)


10. ODI: Coal is given too much credit for alleviating extreme poverty – continued investment in the polluting fossil fuel endangers the Sustainable Development Goals (Report)


11. Bloomberg: 62 million households in India lack access to the electricity grid. But with a 92% growth rate, rooftop solar is becoming an affordable answer (Report)
