Another trick from the automobile industry?
Despite having the same exhaust system, some diesel cars emit more than twice nitrogen oxide than a trailer of 18 tons. And besides, it is legal. This is the case of Mercedes “C 220 CDI” with a nitrogen oxide emission of 643 mg/km compared to 250 mg/km from the cargo truck “Actros 1848”.
The reason is that to get the truck’s permission of use, a test under real conditions is carried out. By contrast, for the automobile the permission is gotten only by fulfilling theoretical values obtained from the laboratory.

Technology to serve sustainability
Technology aims to serve and ease human beings’ daily activity. This blog has the goal to show how technology, in particular through some “apps”, support the monitoring, control, recommending and/or fostering sustainable habits in the citizens. Some of these apps are:
Each time you do something that shows you made an effort toward sustainability, the app rewards you with badges, points and pins. For instance, if you remember to use a reusable coffee mug versus paper cup, points for you! It works in a community, so that you can compare your performance with that of your friends. Also the bonus feature of JouleBug is the option to sync up to utility bills to see just how much is saved each month.
Available: Android, iOS.

INNOVATION FOR SUSTAINABILITY
In October, it was celebrated the Catalonia Ecodesign Award 2015. Among the projects of interest in the area digital and sustainability, the following can be mentioned:
It’s a compact luminary with LED technology that offers high lighting efficiency and visual comfort on an elegant and compact design. It stands out because of integrating concepts of the circular economy like lengthen the useful lifecycle of the product and its design for dismantle.
It’s a technological system aimed to the optimisation of irrigation at the agricultural and gardening sector. It’s monitors and controls take into account meteorology and therefore provides the necessary water to the plants. It can be used by remote control from a computer, smartphone or tablet.

Strategies to tackle Climate Change
The Climate Summit is over and it has produced what was called a successful agreement among almost all countries in the world. 186 from the 195 participant countries in the summit have already committed to make and implement national plans -and to review them every 5 years- to fight against climate change. The main points treated on the agreement are:
- The global temperature increase must remain below 2°C by the end of the century
- By the mid-century it should be reached an “equilibrium” among emissions and the capability to absorb them, mainly CO2
- It is a legal binding agreement. However the national emission reduction goals will not be binding.
- A finance of around USD 100.000 million for developing countries as of 2020
- It will be reviewed every 5 years
- Every country should made a national inventory of emissions to allow measurement, control and improvement.
According to the national plan strategies set on the table the result of their implementation will be still an increase of 3°C in the global temperature. Therefore the importance of stricter strategies which involve bigger commitment from all stakeholders, including business and civil society; the use of new technologies; and the national 5-year plan reviews. Some strategies from national plans will include some of following elements:
