AdBlue® / DEF/ ARLA 32 Background


Global Warming & Greenhouse Effect
Climate change is one of the most serious environmental threats facing the world today. Its impacts will be felt across the world, as sea level rise threatens the existence of some small island states and puts millions of people at risk. Temperature increases, drought and flooding will affect people's health and way of life, and cause the irreversible loss of many species of plants and animals.

Global Surface Temperatures have Increased

Average global surface temperatures have increased by 0.74°C over the past one hundred years. According to the Intergovernmental Panel on Climate Change (IPCC) the strong warming of the last 50 years cannot be explained by natural climate variations alone, but requires the inclusion of the effects of human emissions.

Greenhouse Gases
​The Global Atmosphere Watch (GAW) programme of the World Meteorological Organization (WMO) promotes systematic and reliable observations of the global atmospheric environment, including studies of the biogeochemical cycles of CO2, CH4, N2O, and other long-lived greenhouse gases. The data on the mixing ratios of greenhouse (CO2, CH4, CFCs, N2O, etc.) and related reactive (O3, CO, NOx, SO2, VOC, etc.) gases in the atmosphere and the ocean are collected and distributed by the World Data Centre for Greenhouse Gases (WDCGG) at the Japan Meteorological Agency. The GAW Scientific Advisory Group for Greenhouse Gases (SAG-GHG) oversees the programme (outline on page 46 to 53 of the GAW Strategic Plan for 2008-2015). GAW also issues the annual Greenhouse Gas Bulletin, which reports on the latest trends and atmospheric burdens of the most influential, long-lived greenhouse gases, carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), as well as a summary of the contributions of the lesser gases.

Key Impacts
​However effective policies are to reduce emissions of greenhouse gases, the world will now experience a significant degree of climate change.

Therefore, in order meet the strict regulation and lower and emission, Many countries and companies are dedicated to developing Biofuel, Hybrid and fuel cell cars for meeting the soaring demand of market.For current hiking fuel’s price, SCR is the best way and will become mainstream system.
