Best Ratio of Potential Chemical Energy vs. Cleanliness of Burn

Just wondering what would be the best ratio would be. Diesel has a high energy content but is very dirty. Gas/petrol is lower energy content, but cleaner. Is there any other fuel that would have a better ratio (maybe alcohol, natural gas, propane, bio-fuel, etc.)? I know bio-fuel is essentially zero carbon footprint, but leaving out the whole growing it first takes out CO2 thing...
