The case for environmental fiscal reforms in Bangladesh

with Dr. Sadiq Ahmed (Vice-Chairman, Policy Research Institute of Bangladesh)


The 2041 Perspective Plan seeks to transform Bangladesh from lower middle income to an upper middle-income country by 2031 and eventually to a high-income country by 2041. These are highly ambitious but laudable targets.  If the government is serious about achieving or even approaching these targets then they must pay attention to increasing the annual average GDP growth rate to 8% plus and sustain this over the longer term.

The sustainability of growth is a serious challenge owing to the severe environmental degradation and the continued heavy toll from natural disasters that are being exacerbated by climate change.  The frequent large losses of capital and income and the continued large poverty incidence in districts that are adversely affected by environmental degradation and climate change are examples of the tasks ahead.

The current growth strategy has taken its toll on the environment and the quality of natural resources in Bangladesh. While combating the disastrous effects of climate change remains a priority, the government also needs to ensure that the adverse impact on the natural environment emerging from domestic policy choices – in particular, economic policies relating to manufacturing, construction and power generation – are minimised. A prudent economic growth policy that minimises such negative externalities may be termed as a ‘green growth’ policy.

Fortunately, there is a growing recognition amongst policymakers in Bangladesh of the environmental damage of continuing with the business-as-usual development strategy and the risk it poses to the sustainability of development. Environmental activism has increased at the public fora and among policymakers. This activism has gained momentum since the global attention to climate change and the recognition in Bangladesh that the country is especially susceptible to the downside risks presented by the interaction of the climate change with geography and the ongoing environmental degradation.

The increasing concern with environmental degradation and the risks of climate change has led the government to adopt a large array of strategies, laws, rules and regulations, and adaptation and mitigation programmes and projects. But the results on the ground suggest that their implementation has been weak. One major problem of the past is the inadequate integration of environmental concerns in the national development strategies and the annual budgets. The Bangladesh Delta Plan and the Perspective Plan 2041 seeks to address this strategic gap.  More fundamentally, the financial and institutional constraints have been paramount in limiting the effectiveness of the implementation of the government’s environmental protection strategy.

Research done for the Perspective Plan 2041 suggests that in order for Bangladesh to implement a green growth strategy to ensure consistency of growth and poverty reduction targets with environmental protection, Bangladesh needs to increase its spending on environmental protection and climate change related programmes from 1% of GDP now to 3% of GDP by FY2031 and to 3.5% of GDP by FY2041.

Towards an environment-focused fiscal policy

According to OECD: “Environmental fiscal reform” (EFR) refers to a range of taxation and pricing measures which can raise fiscal revenues while furthering environmental goals. This includes taxes on natural resource exploitation or on pollution. EFR can directly address environmental problems that threaten the livelihoods and health of the poor. EFR can also free up economic resources or generate revenues that can help to finance access of the poor to water, sanitation and electricity services.”

This general idea of using taxes and subsidies to eliminate the gap between social and private benefits and costs have caught the imagination of environmental economists and policymakers. Since many of the environmental services like clean air and clean surface water bodies (ponds, lakes, rivers) are in the nature of public goods, private producers and households left to themselves would tend to contribute to excessive pollution of these services. In Bangladesh, air pollution and surface water pollution are mainly caused by the irresponsible and unchecked behaviour of factories and households undertaking activities that generate CO2 and other gaseous emissions, release various air pollutants through construction activities, and dump solid and liquid wastes into water bodies that pollute them. By imposing a pollution tax, economic agents will get an incentive to control their behaviour. This “polluter-pays-principle” along with the “beneficiary-pays-principle”, which requires that a beneficiary must pay the full cost of the good and service consumed, has now become common language underlying the application of good-sense economic principles to the design of sound environmental management policies.

At the theoretical level, the rationale for environmental taxation was first developed by the British economist Sir Arthur Pigou.  He argued that when a private producer is not held accountable for all the costs incurred by the producer because some of the costs are not reflected in the financial cost of production (external diseconomies), there will be an over-production of that good and the external cost will be passed on to the society at large. In practice, a Pigouvian tax in developing countries is a realistic proposition. The potential benefits that arise from a shift in incentives and raising additional funding for public spending make it an attractive policy tool, albeit one that has to be carefully designed, and reviewed periodically.

International experience offers valuable lessons

The most use of environmentally related taxes for improving environmental outcomes has happened in OECD countries. In 2005 some 375 such taxes existed in OECD countries, yielding an estimated 2-2.5% of GDP as revenue. Some 90% of these revenues came from taxes on gasoline and motor vehicle taxes. Over time, the average revenue yield has come down, falling to 1.56% of GDP in 2014. Environmental taxation has also caught on in many developing countries including South Africa, China and India.  South Africa has been an active player in using environmental taxes, raising as much as 2.29% of GDP in 2014 (Source: OECD Environmental Taxation Database). In Asia, large emitters of CO2, China and India, are actively seeking to use environmental taxation along with other instruments for improving environmental outcomes.chart_140

Several lessons emerge from the review of experiences with EFR that should inform the debate on the formulation of EFR for Bangladesh. First, the use of EFR requires the presence of appropriate legal framework and adequate institutional arrangements for the design and implementation of adopted instruments.  While the level of readiness can vary by country, a minimum legal and institutional background is essential for adopting EFR. Second, administrative costs of tax collection should be minimized through a proper design such that the taxpayer does not feel harassed or that the transaction costs are high. Third, there is often public scepticism (exploited by political leaders) that environmental taxes are primarily new ways of collecting more taxes rather than improving the environment. Countries have tended to rely on a strong information campaign explaining the rationale for the instrument and the possible benefits for the country as a whole. At the same time, taxes should be used gradually with an initially smaller coverage and low rate.

In conclusion

The rationale for adoption of EFR in Bangladesh is clear. First, EFR can help raise public revenues.  This is especially attractive for Bangladesh that has a very low tax to GDP ratio.  Second, the incidence of air and water pollution in Bangladesh is amongst the worst in the world. Environmental taxes and subsidies aimed at reducing air and water pollution can be very helpful in improving the environment. Third, Bangladesh has a track record of heavily subsidizing fuel oil with adverse fiscal and environmental consequences as well as contributing to inefficient use. Proper pricing of energy and other publicly provided services that are intimately related to environmental protection, such as water supply, sanitation and waste management, can ensure the efficient use of these resources and protect the environment. Finally, the inadequacy of resources in Bangladesh is a major constraint on public funding for critical growth-enhancing programmes like infrastructure; for spending on health, education, water supply and social protection to support poverty reduction; and for funding major environmental improvement programmes like clean air, clean water, slum upgrading and afforestation. The revenues mobilized from EFR can be a major contributor to help augment public spending for these programs.

Global experience suggests that the main constraint to the use of environmental taxation relates to political economy, and is often confounded by equity concerns. These concerns affect taxes of all kinds, and EFRs are no exception. However, the beauty of the EFR is that it has the potential to combine tax with pro-poor public expenditure measures.
