A. have amounted to 1,866.7 Teragram CO2 equivalent in 2003, an increase of 24 percent compared to emissions in 1990, while accounting for 27 percent of the ((total sum)) of carbon emissions - redundant expression. Incorrect.

B. have amounted to a ((total sum)) of 1,866.7 Teragram CO2 equivalent in 2003, an increase of 24 percent compared to emissions in 1990, while accounting for 27 percent of the ((total sum)) of carbon emissions - same as A.

C. ((has)) amounted to 1,866.7 Teragram CO2 equivalent in 2003, an increase of 24 percent compared to emissions in 1990, while accounting for 27 percent of the ((total sum)) of carbon emissions - usage of "has" and total sum is incorrect.

D. have amounted to 1,866.7 Teragram CO2 equivalent in 2003, an increase of 24 percent compared to emissions in 1990, while accounting for 27 percent carbon emissions - the errors have been eliminated. Looks good. Hold.

E. have amounted to 1,866.7 Teragram CO2 equivalent in 2003, an ((increase)) of 24 percent ((more)) compared to emissions in 1990, while accounting for 27 percent of the ((total sum)) of carbon emissions - full of redundancy.

Hence, D is the best.

IMO the answer should be D. "Total sum" is redundant expression. Only D removes this redundancy.

1. Carbon emissions are plural, so C is out.
2. Ammount to + sum - redundant -----> B is out.
3. " accounting for 27 percent of the total sum of carbon emissions" makes no sense. We do not need "sum" here -----> A, E are out.
4. "more compared to" in E is wrong. If we want to compare smth with smth we use "more than", "compare to" and so on, but not together.

So, D.

IMO, Ans A

B: Redundancy: "a sum of" unnecessarily repeated

C: SV error

D: Meaning not same as Original: 27% of total sum is not same as 27%

E: Redundancy: Increase + More

Well, in general percentage is always expressed in reference to 'something' as 'x% of something'. That something is missing in D.
