SustMeme Clean Air

Published by SustMeme Top 500

Ranking of Top 500 influencers and players active on Twitter in Clean Air - tackling issues from pollution and urban smog, through to indoor air quality and sick building syndrome. Players listed on the leaderboard range from government bodies and campaigning organisations, to specialist contractors and market-leading engineers; from those concerned with policy and best practice, business strategies and design solutions; to innovators in technology and materials, plus experts in emissions monitoring, measuring and metrics. Weekly update day: Tuesday.

The Leaderboard ranks Players on the basis of scores that measure interactions and influence across all major social-media channels and online, with the metrics provided via leading independent platform Klout.

Curated and Managed by Jim McClelland @SustMeme, the data is published by McClelland Media Ltd, in association with the BESA @BESAGroup. As the UK's leading trade organisation for building engineering services contractors, the Building Engineering Services Association (BESA) is championing the need to monitor and improve the air quality in buildings. BESA represents the interests of firms active in the design, installation, commissioning, maintenance, control and management of engineering systems and services in the built environment.
