Human rights, solidarity, sustainability, stewardship, and justice are all moral values that are important to present and new biofuels. The development of biofuels should not come at the expense of people's fundamental rights (including access to sufficient food and water, health rights, work rights and land entitlements). Biofuels should have a long-term environmental impact. Biofuels should help to reduce total greenhouse gas emissions while also not exacerbating global warming. Biofuels should be developed in accordance with fair trade standards that respect people's rights to reasonable compensation. The costs and benefits of biofuels should be evenly distributed.
