Biofuels
and the Environment
Leading
investors have joined the growing chorus of concern about governments and
companies rushing into producing biofuels as a solution for global warming,
saying that many involved in the sector could be jeopardising future profits if
they do not consider the long-term impact of what they are doing carefully.
It
is essential to build sustainability criteria into the supply chain of any
green fuel project in order to ensure that there is no adverse effect on the
surrounding environment and social structures. The report produced by the
investors expresses concern that many companies may not be fully aware of the
potential pitfalls in the biofuel sector.
Production
of corn and soya beans has increased dramatically in the last years as an
eco-friendly alternative to fossil fuels but environmental and human rights
campaigners are worried that this will lead to destruction of rain forests.
Food prices could also go up as there is increased competition for crops as
both foodstuffs and sources of fuel. Last week, the UN warned that biofuels
could have dangerous side effects and said that steps need to be taken to make
sure that land converted to grow biofuels does not damage the environment or
cause civil unrest. There is already great concern about palm oil, which is
used in many foods in addition to being an important biofuel, as rain forests
are being cleared in some countries and people driven from their homes to
create palm oil plantations.
An
analyst and author of the investors' report says that biofuels are not a cure
for climate change but they can play their part as long as governments and
companies manage the social and environmental impacts thoroughly. There should
also be greater measure taken to increase efficiency and to reduce demand.
