The study highlighted the number of car trips, and the corresponding amount of emissions, saved.
Estimates of emissions saved by using crops for energy should instead focus on biomass that would "maintain or build carbon stocks in plants and soils," it adds.
Gaia also argues that the UN's methodology for assessing whether projects should be granted CDM credits does not take into account the emissions saved by recycling.
Deep problems in Europe's carbon trading scheme – its flagship climate change policy – are set to cancel out over 700m tonnes of emissions saved through renewable energy and energy efficiency efforts, according to a new report.
Alcoa calculates that if established trends in production efficiency, emissions and use of aluminum in vehicles continue, by 2017 the total tonnage of greenhouse gas emissions saved a year by using aluminum in vehicles will exceed the total amount produced by the industry.

The individuals participating in the experiment who were asked the questions to elicit weights reported a difficulty in attaching a value to the attributes described by total hours saved in a year and PM emissions saved in a year.
The purpose of this study is to quantify the total amount of CO2 emissions saved by the method presented in the particular phase of material selection within the life cycle of a building.
