Microsoft has created software that allows cities to track their carbon emissions.
Project Two Degrees works by allowing users input data on emission producing activities such as fuel and electricity consumption, vehicle traffic, waste production, industrial processes and air and sea vessel fuel use. The software then converts the data into tons of CO2 equivalent, taking into consideration the source and type of energy and fuel used.
The tool allows governments to then create an action plan to reduce greenhouse gas emissions. Users are also able to provide access for third-party verification of inventory data accuracy. The action plan section allows cities to set parameters to predict future green house gas emissions and establish reduction goals.
Cities can then plan reduction measures and see how those goals will reduce emissions over time.
This type of software could also be useful to businesses, especially if a cap and trade system came into effect. It would also be useful in eradicating claims of greenwashing.
Tuvalu, the world’s forth smallest nation and one of the hardest hit by the effects of climate change, hopes to rely solely on clean energy by 2020.
The island, located between Australia and Hawaii, is seeing rapidly rising sea levels.
The country’s largest football stadium has already been covered in solar panels which now supplies 5% of the energy needed by the country’s capital.
After only 14 months, the first step in Tuvalu’s mission has reduced consumption of generator fuel shipped from New Zealand by 17,000 tons and saved 50 tons of CO2 from being released in the atmosphere.
Experiments in the early 1990s that seeded a region of the Pacific Ocean with iron dust saw a phenomenal 20 fold increase in the local phytoplankton population, with a corresponding decline in atmospheric carbon dioxide by roughly 2,500 tons within a period of 2 weeks.
California-based Planktos Inc. believes this process can be repeated on a large scale to put a serious dent in our excess carbon dioxide problem.Since 1980, global levels of phytoplankton have dropped 25%. This is significant because phytoplankton, tiny floating surface algae, perform 50 percent of Earth’s photosynthesis. The result of this is the production of 50 percent of our oxygen, and removed half of our carbon dioxide. At 1980 levels, this meant the metabolism of 50 gigatons of carbon dioxide each year. Since 1980, the loss in phytoplankton has resulted in a reduction of carbon dioxide metabolism of nearly 3 gigatons; equivilant to approximately half of all industrial and automotive emissions each year.
If this were carried out on a large scale, it could have the effect of reducing our atmospheric carbon dioxide outputs by up to 50 percent and locking it up forever as chalk on the ocean floor. This would need to be done very carefully though, as we still know relatively little about deep ocean ecosystems and the sudden influx of large amounts of calcified algae might have unintended side effects. However, compared with the alternative of unrestrained carbon dioxide emissions, this seems like a very good avenue to explore.
Wissner-Gross estimates every second someone spends browsing a simple web site generates roughly 20 milligrams of C02. Whether downloading a song, sending an email or streaming a video, almost every single activity that takes place in the virtual environment has an impact on the real one.
As millions more go online each year some researchers say the need to create a green Internet ecosystem is not only imperative but also urgent.
“It is part of the whole sustainability picture,” Chris Large, head of research and development at UK-based Climate Action Group, told CNN.
A number of studies have highlighted the growing energy demands of computers. A 2007 report from research firm Gartner, for example, estimates the manufacturing, use and disposal of information and communications technology generates about two percent of the world’s greenhouse gases — similar to the level produced by the entire aviation industry.
