In the modern world, problem of environmental pollution with various toxic emissions is growing more and
 more. Exhaust or exhaust gases internal combustion engines are one those man-made factors. All countries
 impose restrictions on concentration hazardous substances, for example: Euro - cars, Tier and Stage
 heavy equipment MARPOL-73/78, which regulates from maritime transport...
Delivering net zero emissions requires changing patterns of energy generation, consumption and land use. Mitigation efforts so far have mostly focused on reducing the intensity energy. Future decarbonisation must look outside sector to disrupt markets, infrastructure, systems behaviour. This study quantifies disruption technological markets individual behaviours embodied in possible pathways fo...
An important source of anthropogenic greenhouse gas (GHG) emissions is the air transport sector, which accounts for approximately 2% of global GHG emissions. Therefore, reducing GHG emissions from aircrafts has become a major challenge for transportation authorities worldwide. In recent years, much research has focused on tax ideas related to the CO2 emissions produced by air transport, such as...
We compare emission cap commitment that restricts total emissions and emission intensity commitment that restricts emissions per unit of output as measures of self-regulation. The monopolist chooses either emission cap commitment or emission intensity commitment and sets the target level under the constraint that the resulting emissions do not exceed the upper limit. We find that profit-maximiz...
Long term measurements in background air (Cape Grim, Tasmania) and firn air (NEEM, Greenland) of the potent long-lived greenhouse gas SF5CF3 show that emissions declined after the late 1990s, having grown since the 1950s, and became indistinguishable from zero after 2003. The timing of this decline suggests that emissions of this gas may have been related to the production of certain fluorochem...
