>Tobacco smoking leads directly to the emission of 2 600 000 tonnes of carbon dioxide and about 5 200 000 tonnes of methane.19 Data from 66 low- and middle-income countries showed that tobacco growing and curing caused significant deforestation between 1990 and 1995, amounting to approximately 2000 hectares – on average, 5% of each country’s estimated deforestation during that five-year period.20 Worldwide, approximately 13 000 000 hectares of forest are lost due to agriculture or natural causes each year,21 and of this, at least 200 000 hectares are for tobacco agriculture and curing.1 Deforestation is the second largest anthropogenic source of carbon dioxide to the atmosphere (approximately 20%), after fossil fuel combustion.22 One estimate of the impact of deforestation in tobacco agriculture and curing is that it causes almost 5% of global greenhouse gas production.23
