Nature: Up to one-third of US in compliance with Kyoto accords

24.11.2005


Regions’ GDP equivalent to globe’s second largest economy



Even though the United States does not participate in the Kyoto protocol, about one-quarter of the population lives in states, counties or cities that have adopted climate change policies similar to those of the global initiative, according to a Brief Communication published in the November 17 issue of Nature.

Including regions classified as ’probable’ and ’possible’ adopters, which have pledged to reduce emissions, more than one-third of the U.S. population lives in such areas, say co-authors Brendan Fisher and Robert Costanza of the University of Vermont.


Together, these regions contribute up to half of the US gross domestic product, equivalent of 16.9% of global GDP, a slightly larger share than Japan, the world’s second largest economy.

Although the numbers look promising, Fisher and Costanza caution that "compliance will be a challenge even for current adopters, who have on average increased their carbon dioxide emissions by 14% since 1990." There are no mechanisms to enforce such initiatives, they add.

However, the local nature of these initiatives could make it possible to develop adaptable, site-specific plans for reducing greenhouse-gas emissions.

The United States produces 24% of worldwide greenhouse-gas emissions.

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

Im Focus: Using graphene to create quantum bits

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.

In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
