Low Carbon Development is in Tanzania has already introduced many low carbon options, for example in the electricity sector. However, these are already included in the estimates above and do not offset the increases in GHG emissions. The study has considered an alternative low carbon pathway for Tanzania, which delivers the same growth levels but reduces emissions. For electricity, this includes the use of alternatives to fossil based generation, including renewables for large-scale generation and the decentralised electricity for rural populations. For households, it includes more efficient use of biomass in addition to higher consumption of other lower carbon fuels, such as renewable electricity and LPG. For the transport sector, it includes improvements in vehicle efficiency, use of biofuels and effective public transport systems. For agriculture, it includes various options to address the emission growth that would occur from agricultural intensification. Many of these options are opportunities, i.e. they have positive economic effects and their benefits outweigh their costs. An example is energy efficiency which saves the individual or company money (e.g. from reduced fuel costs) compared to the current baseline. There are also many low cost options that would enhance economic growth, as well as allowing further access to international carbon credits. These options are shown below, in a marginal abatement cost curve. This shows the cost of emission abatement (left hand axis, in $/tCO2) for increasing total amounts of emissions reduced across the economy (from left to right). Options below the zero line are no regret options, i.e. those that produce cost savings. These options also have wider economic benefits from greater energy security and diversity, reduced air pollution, and reduced environmental impacts. In addition, the forestry sector represents an immediate opportunity, and Tanzania is wellpositioned as a UN-Redd Country.
