Stopping Asia-Pacific being the world's worst polluter

How can we use our resources more efficiently to continue to grow our economies in a manner that does not tax our natural environment or generate pollution affecting public health and ecosystem health? There is certainly much room for improvement to make in this area.

Resources such as fossil fuels, biomass, metals and minerals are essential to build economies. However, the region's resource efficiency has regressed in recent years. Asia is unfortunately the least resource-efficient region in the world. In 2015, we used one third more materials to produce each unit of GDP than in 1990. Developing countries use five times as many resources per dollar of GDP in comparison to the rest of the world and 10 times more than industrialised countries in the region. This inefficiency of resource use results in wastage and pollution further affecting the natural resources and public health which are the basic elements for ensuring sustainable economic growth.

As the speed and scale of economic growth continues to accelerate across the region, pollution has become a critical area for action. While the challenge of pollution is a global one, the impacts are overwhelmingly felt in developing countries. About 95% of adults and children who are impacted by pollution-related illnesses live in low and middle-income countries. Asia and the Pacific produces more chemicals and waste than any other region in the world and accounts for the bulk -- 25 out of 30 -- of cities with highest levels of PM2.5, the tiny atmospheric particulate matter that can cause respiratory and cardiovascular diseases and cancer. More than 80% of our rivers are heavily polluted while five of the top land-based ocean plastic sources are from countries in our region. Estimates put the cost of marine pollution to regional economies at a staggering US$1.3 billion.

If left unattended, these trends threaten hard-won economic gains and hamper human development. But while these challenges appear intractable, the region has tremendous strengths and opportunities to draw from. Many countries hold solid track records of successful economic transformation. The capacity for promoting environmental sustainability as an integral pillar of sustainable development must now be developed across all countries in the region

There are some profound changes under way. The region is experiencing the largest rural to urban migration in history. Developing these new urban areas with resource-efficient buildings, waste water and solid waste management systems can do much to advance this agenda. Advancing the "sharing economy" might mean we have better utilisation of assets such as vehicles, houses or other assets, greatly reducing material inputs and pollution. The widespread move to renewable energy should rein in fossil fuel use. And advances in recycling, materials technology, 3D printing and manufacturing could also support greater resource circularity.

Moving to green technologies and eco-innovation offer economic and employment opportunities. Renewable energy provided jobs for 9.8 million people worldwide in 2016. Waste can be converted into economic opportunities, including jobs. In Cebu City, the Philippines, concerted Solid Waste Management has borne fruit: Waste has been reduced by 30% in 2012; treatment of organic waste in neighbourhoods has led to lower transportation costs and longer use period in landfills. The poor have largely benefited from hundreds of jobs that have been created.

At the policy level, it is vital that resource efficiency and pollution prevention targets are integrated into national development agendas, and targeted legal and regulatory measures to enforce resource efficiency standards should be established. For example, China has instituted a national system of legislation, rules and regulations that led to the adoption of a compulsory national cleaner production audit system that has been in place for more than 10 years. The direct economic benefits from this system are estimated to be more than $3 billion annually.

Further, we need an urgent reform of financial instruments. Too little capital is supporting the transition to green and resource-efficient economy -- a major portion of current investments is still in high-carbon and resource-intensive, polluting economies. The polluter-pays principle and environmental externalities are not yet fully integrated into pricing mechanisms and investment models. The availability of innovative financing mechanisms and integrated evaluation methods are important for upscaling and replicating resource-efficient practices. For example, the large-scale promotion of biogas plants in Vietnam was made possible by harnessing global climate finance funds. Several countries in the region, such as Indonesia and Sri Lanka, have developed comprehensive, systemic approaches that embed sustainable finance at the heart of financial market development. We should draw from the lessons learned from these experiences.

Resource efficiency and pollution prevention must be recognised as an important target for action by science, technological and innovation systems. This is vital for the ongoing development of technology, and for scaling up technologies. Research shows developing countries could cut their annual energy demand by over half, from 3.4% to 1.4% over the next 12 years. This would leave energy consumption some 22% lower than it would otherwise have been -- an abatement equivalent to the entire energy consumption in China today.

We need to move to a more resource-efficient and pollution-free growth path that supports and promotes healthy environments. The cost of inaction for managing resources efficiently and preventing pollution is too high and a threat to economies, livelihoods and health across the region.
