The retrofit category is also making strides, thanks to the pressing demand to enhance older engines using emission-curtailing technologies.
The new stricter emission norms imposed by the governments are implying that businesses and consumers look for a cost-effective solution, potentially retrofitting (upgrading existing) engines with modern catalytic solutions.
Merchant and environmental regulations are getting stricter, which can be attributed to the negative effects of small engines on the environment and human health, such as air pollution and greenhouse gas emissions, leading to increased demand for emission control catalysts.
Gradual implementation of emission regulations for some categories of small engines Roadblocks to Business Entry in Developing and Emerging Markets, Higher capital requirements and competition in the Small Engine Emission Control Catalyst Market need to be addressed.
