international institutions the possibility to setup an open data framework. Here are a few of the institutions we have engaged: </p> <ul> <li> <a href='https://www.who.int/'>WHO</a> - WHO: World Health Organization <li> <a href='https://www.unep.org/'>UNEP</a> - UNEP: United Nation Environmental Program <li> <a href='https://www.unido.org/'>UNIDO</a> - UNIDO: United Nation Industrial Development Organization <li> <a href='https://wmo.int/'>WMO</a> - WMO: World

</section><h2><p>United Data</p></h2><section><p> The objective of the "Open Data Framework" is to provide unlimited and free access the world historical and real-time Air Quality data from the <a href='/sources/'>100</a>+ countries covered on <a href='https://aqicn.org/here/'>aqicn.org</a> and <a href='https://waqi.info/'>waqi.info</a> </p> <p> Everyone - both institutions as well as citizens - agrees that this is not only a good idea, but that it should just happen. </p> </section><h2><p>One for all and all for one</p></h2><section><p> At the end of the day, developing the data-platform requires financial support. </p> <p> Here is our proposal to the Clean Air Fund: <a href='/air/data-platform/docs/osdms-waqi-eoi.pdf'>Open Source Data Management System (OSDMS)</a> </p> <p> If you are
