The Air Pollution Solutions Initiative focuses on mitigation measures to support social and technological transformation of the brick, open burning (crop and waste), cookstove and transportation sectors through pilots and behavioral change campaigns for reducing air pollution. Until December 2019, this Initiative was known as the Bricks Initiative.

ICIMOD’s Air Pollution Solutions Initiative improves local and regional air quality standards, helps ensure economic benefits for communities, and helps reduce adverse impacts on health by improving regional and international coordination and information sharing.
We have been the lead partner for the Climate and Clean Air Coalition Brick Production Initiative and a lead implementer of the Clean Brick Initiative of the Department for International Development (DFID) in Nepal. The brickmaking process is highly energy- and labour-intensive and releases huge amounts of black carbon into the atmosphere, affecting health and visibility, and accelerating the melting of Himalayan snow and ice.
In South Asia, bricks are produced primarily through processes of hand-molding and baking in fixed chimney bull’s trench kilns (FCBTKs). In recent years, mechanized brick making plants and other varieties of kilns – such as tunnel kilns, the Hoffman kiln, the modified FCBTK, the zig-zag, and the vertical shaft brick kiln (VSBK) – have been introduced and have various trade-offs in terms of productivity and emissions.
This construction drawing and guideline document is an output of the design manual and is based on the structural designs of natural and induced draught zig-zag kilns proposed therein. The aim of this document is to provide step-by-step guidance in the construction of such kilns so that they are structurally safe, earthquake-resistant, energy efficient, low on emissions, worker-friendly, and produce better quality bricks.

What's happening in the region in relation to air pollution
The 120,000 brick kilns scattered across South Asia release huge amounts of greenhouse gases and black carbon into the atmosphere. Commonly known as soot, black carbon is the second biggest global warming pollutant after carbon dioxide; it affects health and visibility and accelerates the melting of Himalayan snow and ice.
We have a deep history of work across a broad range of issues enabling sustainable development in the complex environment of the HKH. We have been protecting the pulse for over three decades.
When most people think of air in the context of the environment, they probably think of air pollution – and that’s part of the picture. But air is a dynamic and delicate mix of chemicals in constant motion, flowing from place to place through atmospheric circulation systems.
Mountains may be rugged and majestic, but they’re also fragile environments that are particularly vulnerable to climate change.
