There are two possible solutions to this problem for a solar collector: (1) find a base fluid which has low emission for long wavelengths and (2) install a cover/glazing over the collector which will trap long-wavelength emitted radiation from leaving the system.
The question is, what is that something?" Natural gas plants have low emissions, but Norris McDonald, the president of the African American Environmentalist Association, said during a break in the hearing that Indian Point had virtually no emissions.
In Brazil, for example, a two-year-old, $250 million program has financed more than 2,000 farming projects to help recover degraded pastures, improve the processing of livestock waste, implement no-till agriculture to increase the life of the soil, plant commercial forests and employ other practices that have low emissions and respond to the changing climate.
Ian Allen from Vauxhall talks about what cars have low emissions while motoring journalist Alistair Weaver say the mayor's plans are very vague.
There may be no software that disables pollution controls, he said — "But it appears they're not necessarily complying with the regulation and its spirit and producing vehicles that actually have low emissions, not only in the laboratory but also on the road".
Low carbon cities are those cities that are self-cleansing or have low emission of carbon.
The 12 new low floor buses will have low emission engines, coach-style seating and increased luggage space.
Biodiesel is fast becoming a popular alternative to fossil fuels, as it is natural, renewable and has low toxic emissions.
Bioenergy is regarded as an attractive, low-carbon energy source because it supports environmentally friendly conversion of biomass to bioenergy, and has low CO2 emissions.
Indonesia also moved up, despite rampant illegal deforestation, because it has low per capita emissions and – according to the report – "improvements can be seen in the renewable and the efficiency scores".
