Projections of future greenhouse gas emissions are highly uncertain. This amounts to about 30% of anthropogenic all carbon dioxide emissions. Capito opposes legislation aimed at capping greenhouse gas emissions. Lower emissions and improved fuel efficiency are achieved. This emission represents the most important individual oceanic emissions of artificial radioactivity ever observed. This is a list of countries by carbon dioxide emissions per capita. Lastly, urbanization curbs pollution emissions by increasing R&D and innovations. This has the added benefit of reducing carbon emissions. There are substantial uncertainties in the measurement of net carbon emissions. The effect of PHEVs on greenhouse emissions is complex. This sector also accounts for 8.4% of Canada's Greenhouse gas emissions. Motor vehicles are responsible for the main atmospheric pollutant emissions. Catalytic converters have proven to be reliable and effective in reducing noxious tailpipe emissions. British Columbia has been making strides with regards to reducing their carbon emissions. The model can further predict future distributions based on environmental emissions data.
