As every week goes by, a theme emerges or re-emerges in the climate and environment debate. Some of these themes linger others move on quickly. In the last month, a theme has been better measurement. It has been raised in the context of water, national grids and fuel efficiency in cars. The IT industry has sensed an opportunity and groups like IBM and Google are finding ways to make metering smart and in real time. In parts of the car industry telemetrics has been an enduring theme.
