    "description": "Which factory in my city is the largest emitter of CO2? Which industrial sector is\r\nresponsible for the largest share of a country's contribution to climate change? It\r\nshould not be difficult to answer these questions. Public databases and reporting\r\nrequired by international agreements usually allow us to access this data.\r\n\r\nHowever, trying to access and work with these datasets — or, shall we say, Excel tables\r\n— can be frustrating. UN web pages that prevent easy downloads with a \"security\r\nfirewall\", barely usable frontends, and other issues make it needlessly difficult to\r\ngain transparency about the sources of climate pollution.\r\n\r\nWhile working with official EU datasets, the speaker observed data points that could not\r\npossibly be true. Factories suddenly dropped their emissions by orders of magnitude\r\nwithout any explanation, different official sources report diverging numbers for the\r\nsame emission source, and responsible European and National authorities appear not to\r\ncare that much.\r\n\r\nThe talk will show how to work with relevant greenhouse gas emission data sources and\r\nhow we can access them more easily by converting them to standard SQL tables. Furthermore, we will dig into some of the\r\nstrange issues one may find while investigating emission datasets.\r\n\r\n# Background / Links\r\n\r\n* Why is it needlessly difficult to access UNFCCC Emission Data?
