Company Carbon Death Map

, ,

Winner: Transparency Prize

The judges say:

Company Carbon Deathmap hits two audiences: it’s provocative and could be used to apply pressure to industries, equally it helps bring visibility of risk to mainstream investors.

Description

The FTSE 100 group of companies are valued by the market based on expectations about their future earning potential. But the huge assets of fossil fuels owned and used by the companies pose a systemic risk their earning potential. Given that future emissions of carbon dioxide are highly constrained if we are to avoid climate change, companies sitting on large stocks of carbon are likely to see the value of these commodities reduce as they become increasingly difficult to use…

…so how does the current valuation of companies change if we take this into account?

Greensta

,

Description

Investigating the outlook for our standard of living.

We analyse trends of salary inflation vs energy cost increase and general inflation to demonstrate that our standard of living is set to decrease unless:-

  • We personally have above inflation pay rises
  • We reduce the amount we spend on energy/food/products

The details asked during our survey are personal and highlight a real problem in the mid to long term for all of us.

Our current economic system is untenable and we’ll need to make some huge changes in the coming decades.

Kindle Energy Dashboard

Winner: Innovation Prize

The judges say:

We had only one word to describe this innovation: Awesome.

MQTT Kindlet

Description

Making use of an energy-efficient, lightweight, portable, and highly “”glanceable”” device – the e-Ink Amazon Kindle – to connect to energy data delivered over the lightweight MQTT protocol.

The app requires the Kindle to be “jailbroken”, and uses data publically available from bmreports and the realtime carbon site powered by AMEE, via test.mosquitto.org

The idea is to generate dashboard images to use as screensavers on the Kindle when it is “sleeping”.
