Hidden impact of semiconductor manufacturing on climate change
Semiconductor manufacturing contributes to 31% of global greenhouse gas emissions, and the increasing usage of electronic chips drives this upward trend. The production of smart meters and other electronics requires a substantial amount of electricity and fossil fuels. Improving product quality and longevity is crucial to combat the negative impact of product manufacturing on the environment.
toi.in/, Mar. 22, 2023 –
A very promising Annual Union Budget 2023-24 of India continues to focus on infrastructure development. The capital outlay for infrastructure was announced at more than US$ 100 billion, which is ~ 3.3% of GDP. Out of which, it is pledged to invest US$4.3 billion in green technology to clean up the country's economy. This massive investment calls for huge government and also market procurements across sectors.
Global efforts to address climate change: A multidimensional approach
From the Kyoto protocol in 1992 until the recent CoP-27 conference in Sharm el-Sheikh, Egypt in November 2022, over 2,860 laws and policies related to climate change have been implemented by 193 countries and the European Union. These policies include 2,203 measures to reduce emissions, 1,338 provisions for adapting to climate change, and 424 aimed at reducing catastrophic risks. According to the Climate Change Laws of the World (CCLW) database, policymakers' policies related to electricity, forestry, food security, land use, transportation, and energy have received the most attention. It appears that addressing climate change requires a multi-dimensional approach that covers both the supply and demand aspects of decarbonisation to tackle this global crisis effectively.
Backed up by global affluence, our headcount is projected to touch 10 billion by 2060. This entails doubling raw material consumption across economies. Though UN "Sustainable Development Goal (SDG) 12.2" targets efficient use of resources, there is a little conscious realisation of the energy and material consumption that takes place while manufacturing the products. Reports indicate that manufacturing contributes to 31% of global greenhouse gas emissions (~50 billion tons per year). This is more than electricity generation, contributing to 27% of the total emission. There is a continuous increment in the contribution to emissions through manufacturing. Contrary, the demand for steel, the primary metal in our society, is decreasing by 2% annually. Transport on the road and by air is becoming much more efficient. Aircraft nowadays are 70% more efficient than those in 1958.
