I've been significantly cutting back on meat and diaries from my diet since last year. It's probably the biggest individual contribution one can make for the environment, in terms of greenhouse-gas and agricultural land required to mantain livestock. Nutritional alternatives are easily accessible both economically and locally, making it much easier to stick to it. But as the studies show, there needs to be a major shift in food production process to curb out global climate change and poverty led malnourishment.
So the question around policy making and decision making needs to be aggressively brought onto the table. Common sense would indicate that it would be met with universal animosity, however, historical evidence around sugar taxes and solidly constructed focus groups would indicate that - with the right messaging - it could be a viable policy with many significative positive impacts. Would meat eating GAF be on board with such measures? How do we get there?
The projected rise in food related greenhouse gas emissions could seriously impede efforts to limit global warming to acceptable levels. Despite that, food production and consumption have long been excluded from climate policies. In part due to concerns about the potential impact on food security. Using a coupled agriculture and health modeling framework, we show that the global climate change mitigation potential of emissions pricing of food commodities could be substantial, and that levying greenhouse gas taxes on food commodities could, if appropriately designed, be a health-promoting climate policy in high income countries, as well as most low and middle income countries. Sparing food groups known to be beneficial from taxation, selectively compensating for income loses associated with tax-related price increases, and using a portion of tax revenues for health promotion are potential policy options that could avert most of the negative health impacts experienced by vulnerable groups, whilst still promoting changes towards diets which are more enviromentally sustainable.

Taxing the meat and dairy industries for their impact on climate would lead to lower emissions and save about half a million lives per year, according to the first global study of the issue, published Tuesday.
A 40 percent fee on beef and a 20 percent fee on dairy would counter the industries' impact on climate change, as livestock release significant greenhouse gases while exacerbating deforestation, and would encourage people to consume less of eachwhich in turn would improve global health, according to the Oxford Martin Program on the Future of Food, part of the University of Oxford.
The study (pdf), published in the journal Nature Climate Change, finds that raising the price of beef by 40 percent would lead to a 13 percent decrease in consumption.
It is also the latest evidence that keeping global emissions below 2°C and preventing widespread irreversible damage cannot happen without global food system reform. Other recent studies have found that not only is Big Agriculture incapable of "feeding the world" as biochemical giants like Monsanto have promised, but that the focus must actually be on empowering local, small-scale farmers.
The United Nations warned last month that millions more people are at risk of being pushed into poverty and starvation by 2030 without radical system change.
"The food system is responsible for more than a quarter of all greenhouse gas (GHG) emissions, most of which are related to livestock," the study states. "[R]educing the GHG emissions related to food production will have to become a critical component of policies aimed at mitigating climate change."
Lead researcher Marco Springmann told the Guardian on Tuesday, "It is clear that if we don't do something about the emissions from our food system, we have no chance of limiting climate change below 2°C."
"f you'd have to pay 40 percent more for your steak, you might choose to have it once a week instead of twice," he said.
The study also recommended a 15 percent tax on lamb, 8.5 percent on chicken, 7 percent on pork, and 5 percent on eggs.
And a widespread drop in consumption would save about half a million people a year from deaths related to malnutrition, such as those from heart disease, diabetes, and obesity. He pointed to the recently enacted soda tax in Mexico, which raised soft drink prices by 10 percent in 2014, leading to a 12 percent drop in consumption by the end of that year; the Los Angeles Times noted last week that the tax is poised to "prevent 189,300 new cases of Type 2 diabetes, 20,400 strokes and heart attacks, and 18,900 deaths among adults 35 to 94 years old."
The researchers assessed what kind of charges would need to be levied to make up for the climate impacts of meat and dairy, which have a heavy carbon footprint due to deforestation, methane emissions, and land and water use associated with feeding and keeping cattle. Exempting healthy food groups and using a system that researchers say would not burden low-income consumers with heavy taxes, while targeting a portion of the revenues for health promotion, would ultimately reduce climate emissions by 1 billion tons a year, the study found.
Springmann acknowledged that a meat tax might be a hard pill to swallow for consumers who get defensive over their food choices. But understanding the mission would help endear the public to the idea, he said.
"If people see any food price rise, they get angry, so you have to explain why you are doing it," he told the Guardian. "Either we have climate change and more heart disease, diabetes, and obesity, or we do something about the food system."

Meat production produces 15% of all greenhouse gases more than all cars, trains, planes and ships combined and halting global warming appears near impossible unless the worlds fast growing appetite for meat is addressed.
The new analysis says this could be done through taxes, increasing vegetarian food in schools, hospitals and the armed forces and cutting subsidies to livestock farmers, all supported by public information campaigns.
The research, from the international affairs thinktank Chatham House and Glasgow University, involved surveys and focus groups in 12 countries and found that even measures restricting peoples behaviour could be accepted if seen as in the public interest, as was seen with smoking bans.
Governments are ignoring what should be a hugely appealing, win-win policy, said lead author Laura Wellesley, at Chatham House.
The idea that interventions like this are too politically sensitive and too difficult to implement is unjustified. Our focus groups show people expect governments to lead action on issues that are for the global good. Our research indicates any backlash to unpopular policies would likely be short-lived as long as the rationale for action was strong.
Increasing appetite for meat and population growth in developing countries mean global meat consumption is on track to increase 75% by 2050, which would make it virtually impossible to keep global warming below the internationally-agreed limit of 2C.
Meat consumption is already well above healthy levels in developed nations and growing fast in other countries, and is linked to rising rates of heart disease and cancer. To get to healthy levels, US citizens would need to cut the meat they eat by two-thirds, those in the UK by a half and those in China by a third.
If the worlds population cuts to healthy levels of meat consumption about 70g per day it would reduce carbon emissions by an amount equivalent to annual output of the US, the worlds second biggest polluter.
The UN climate change summit begins in Paris on 30 November, where the worlds nations aim to seal a deal to tackle climate change.
Most countries have already submitted pledges to cut their emissions, but they are not enough to keep warming below dangerous levels. Cutting meat eating to healthy levels would make up a quarter of that shortfall and is very low cost way of curbing emissions, according to the report, but action to achieve this is non-existent.
Previous calls to cut meat consumption, from the chief of the UNs climate science panel and the economist Lord Stern, or to tax it, have been both rare and controversial.
We are not in any way advocating for global vegetarianism, said Wellesley. We can see massive changes [to emissions] from just converging around healthy levels of meat eating. She said raising awareness of the impact on the climate from meat production was the first step, but was unlikely to shift diets by itself.
