CLP Exxon Mobil Emission Stats

Posted by David Wheeler & Kevin Ummel on the CARMA (Carbon Monitoring For Action) Blog on the 16th of November 2007:

Transparency is central to CARMA’s objective of reducing carbon emissions through public disclosure. So when the CLP Group in China approached us about our figures for their Castle Peak power plant in Hong Kong, we took notice and responded promptly. Indeed, it is CARMA’s policy to replace our data if high-quality, plant-specific, independently verified emission reports are available.

Although not all of CLP’s verified emission reports were plant specific, the company came forward with some previously unavailable data that allowed us to revise our original information for a handful of the company’s plants. In the case of Castle Peak, our original figure was revised downward. In the case of the Yallourn plant, our original estimate was revised upward. The net effect of these changes and others was to adjust CLP Group’s total present emissions from 75.3 million to 67 58.9 million tons. They also pointed out that we had incorrectly included a very small plant in the database that was no longer operational — we have removed it.

We also made adjustments after receiving verified emissions data from two small, related Polish companies (Dalkia Lodz and Dalkia Poznan). The net effect of those changes was to revise their aggregate CO2 emissions from 6 million to 4.5 million tons. We applaud both companies for bringing their independently verified emission reports to our attention, and, in the case of CLP Group, making available information that had not previously been public. We believe they set an excellent example for the rest of the power sector, and we hope more companies open up their plants to independent audits and subsequent posting on CARMA.

Clear The Air also have the figures from CLP Exxon Mobil – 13.3 million tonnes of CO2 are pumped into the air per year in Hong Kong. This is 36,438.36 tonnes of C02 per day / 1,518.26 tonnes per hour / 25.3 tonnes per minute/ or 422 kgs of C02 per second into the HK and adjoining atmosphere.

That’s only tossing 1,401 loaded 40′ x 26 tonne containers of carbon into the air per day or 58.3 per hour, far faster than they can manage in the biggest port in the world.

From their website they also managed in 2006 from Castle Peak alone :

  • 98.63 tonnes of Sulphur Dioxide a day
  • 61.64 tonnes of Nitrous Oxides a day
  • 3.83 tonnes of particulate soot a a day (they do not specify the extremely harmful PM2.5 that our noses cannot filter)
