Pelletier N, Pirog R, Rasmussen R (2010). "Comparative life cycle environmental impacts of three beef production strategies in the Upper Midwestern United States", Agricultural Systems 103 (2010) 380–389  This paper compares three US beef rearing systems. Cattle are finished either in: feedlot systems (having received hormone implants); backgrounding systems (also with hormone implants); or on pasture (no implants).

L. Reijnders (2009): Are forestation, bio-char and landfilled biomass adequate offsets for the climate effects of burning fossil fuels?, Energy Policy Volume 37, Issue 8, Pages 2839-2841. Forestation and landfilling purpose-grown biomass are not adequate offsets for the CO2 emission from burning fossil fuels. Their permanence is insufficiently guaranteed and landfilling purpose-grown biomass may even be counterproductive.

In November 2008 the Greater London Authority published a report on London's food related greenhouse gas emissions.

Published by the International Trade Centre in April 2008, Organic Farming and Climate change concludes that organic agriculture has much to offer in both mitigation of climate change through its emphasis on closed nutrient cycles and is a particularly resilient and productive system for adaptation strategies. It also raises the issue of whether organic agriculture should be eligible for carbon credits under voluntary carbon offsetting markets and the Clean Development Mechanism.

A European drive to run vehicles on biofuels instead of petrol and diesel to reduce greenhouse gas emissions is to be reviewed after concerns about its environmental impact.

For a definitive analysis of the impact of aviation on climate change see the Intergovernmental Panel on Climate Change (IPCC) special report Aviation and the Global Atmosphere. The report is attached below.

The Stern Review examines the financial, human and other costs of failing to tackle climate change and concludes that this could amount to trillions of pounds, equivalent to shrinking the global economy by a fifth by 2050.
